WWW::Mechanize::PhantomJS - automate the PhantomJS browser

use WWW::Mechanize::PhantomJS;
my $mech = WWW::Mechanize::PhantomJS->new();
$mech->get('http://google.com');

$mech->eval_in_page('alert("Hello PhantomJS")');
my $png= $mech->content_as_png();

my $mech = WWW::Mechanize::PhantomJS->new();

• autodie

  Control whether HTTP errors are fatal.

    autodie => 0, # make HTTP errors non-fatal
  

  The default is to have HTTP errors fatal, as that makes debugging much easier than expecting you to actually check the results of every action.

• port

  Specify the port where PhantomJS should listen

    port => 8910
  

• log

  Specify the log level of PhantomJS

    log => 'OFF'   # Also INFO, WARN, DEBUG
  

• launch_exe

  Specify the path to the PhantomJS executable.

  The default is phantomjs as found via $ENV{PATH}. You can also provide this information from the outside by setting $ENV{PHANTOMJS_EXE}.

• phantomjs_arg

  Additional command line arguments to phantomjs. (phantomjs -h)

    phantomjs_arg => ["--proxy=$ENV{HTTP_PROXY}"]
  

• launch_ghostdriver

  Filename of the ghostdriver Javascript code to launch. The default is the file distributed with this module.

    launch_ghostdriver => "devel/my/ghostdriver/main.js",
  

• launch_arg

  Specify additional parameters to the Ghostdriver script.

    launch_arg => [ "--some-new-parameter=foo" ],
  

  Some interesting parameters are:

    "--webdriver=$port",
    '--webdriver-logfile=/tmp/webdriver',
    '--webdriver-loglevel=DEBUG',
    '--debug=true',
  
    note: these set config.xxx values in ghostrdriver/config.js
  

• cookie_file

  Cookies are not directly persisted. If you pass in a path here, that file will be used to store or retrieve cookies.

• ignore_ssl_errors

  If you want phantomjs to ignore SSL errors, pass a true value here.

• driver

  A premade Selenium::Remote::Driver object.

• report_js_errors

  If set to 1, after each request tests for Javascript errors and warns. Useful for testing with use warnings qw(fatal).

print $mech->phantomjs_version;

Returns the version of the PhantomJS executable that is used.

print $mech->ghostdriver_version;

Returns the version of the ghostdriver script that is used.

my $selenium= $mech->driver

Access the Selenium::Driver::Remote instance connecting to PhantomJS.

print for $mech->js_alerts();

An interface to the Javascript Alerts

Returns the list of alerts

$mech->clear_js_alerts();

Clears all saved alerts

print $_->{message}
    for $mech->js_errors();

An interface to the Javascript Error Console

Returns the list of errors in the JEC

Maybe this should be called js_messages or js_console_messages instead.

$mech->clear_js_errors();

Clears all Javascript messages from the console

Records a confirmation (which is "1" or "ok" by default), to be used whenever javascript fires a confirm dialog. If the message is not found, the answer is "cancel".

my ($value, $type) = $mech->eval( '2+2' );

Evaluates the given Javascript fragment in the context of the web page. Returns a pair of value and Javascript type.

This allows access to variables and functions declared "globally" on the web page.

This method is special to WWW::Mechanize::PhantomJS.

$mech->eval_in_phantomjs(<<'JS', "Foobar/1.0");
    this.settings.userAgent= arguments[0]
JS

Evaluates Javascript code in the context of PhantomJS.

This allows you to modify properties of PhantomJS.

my @links = $mech->selector('a');
$mech->highlight_node(@links);
print $mech->content_as_png();

Convenience method that marks all nodes in the arguments with

background: red;
border: solid black 1px;
display: block; /* if the element was display: none before */

This is convenient if you need visual verification that you've got the right nodes.

There currently is no way to restore the nodes to their original visual state except reloading the page.

$mech->get( $url  );

Retrieves the URL URL.

It returns a faked HTTP::Response object for interface compatibility with WWW::Mechanize. It seems that Selenium and thus Selenium::Remote::Driver have no concept of HTTP status code and thus no way of returning the HTTP status code.

Note that PhantomJs does not support download of files.

$mech->get_local('test.html');

Shorthand method to construct the appropriate file:// URI and load it into PhantomJS. Relative paths will be interpreted as relative to $0.

This method accepts the same options as ->get().

This method is special to WWW::Mechanize::PhantomJS but could also exist in WWW::Mechanize through a plugin.

Warning: PhantomJs does not handle local files well. Especially subframes do not get loaded properly.

not implemented

Selenium currently does not allow a raw POST message and the code for constructing a form on the fly is not working so this method is not implemented.

$mech->post( 'http://example.com',
    params => { param => "Hello World" },
    headers => {
      "Content-Type" => 'application/x-www-form-urlencoded',
    },
    charset => 'utf-8',
);

Sends a POST request to $url.

A Content-Length header will be automatically calculated if it is not given.

The following options are recognized:

• headers - a hash of HTTP headers to send. If not given, the content type will be generated automatically.
• data - the raw data to send, if you've encoded it already.

$mech->add_header(
    'X-WWW-Mechanize-PhantomJS' => "I'm using it",
    Encoding => 'text/klingon',
);

This method sets up custom headers that will be sent with every HTTP(S) request that PhantomJS makes.

Note that currently, we only support one value per header.

$mech->delete_header( 'User-Agent' );

Removes HTTP headers from the agent's list of special headers. Note that PhantomJS may still send a header with its default value.

$mech->reset_headers();

Removes all custom headers and makes PhantomJS send its defaults again.

my $response = $mech->response(headers => 0);

Returns the current response as a HTTP::Response object.

$mech->get('http://google.com');
print "Yay"
    if $mech->success();

Returns a boolean telling whether the last request was successful. If there hasn't been an operation yet, returns false.

This is a convenience function that wraps $mech->res->is_success.

$mech->get('http://google.com');
print $mech->status();
# 200

Returns the HTTP status code of the response. This is a 3-digit number like 200 for OK, 404 for not found, and so on.

$mech->back();

Goes one page back in the page history.

Returns the (new) response.

$mech->forward();

Goes one page forward in the page history.

Returns the (new) response.

print "We are at " . $mech->uri;

Returns the current document URI.

Returns the document object as a WebElement.

This is WWW::Mechanize::PhantomJS specific.

print $mech->content;
print $mech->content( format => 'html' ); # default
print $mech->content( format => 'text' ); # identical to ->text

This always returns the content as a Unicode string. It tries to decode the raw content according to its input encoding. This currently only works for HTML pages, not for images etc.

Recognized options:

• format - the stuff to return

  The allowed values are html and text. The default is html.

print $mech->text();

Returns the text of the current HTML content. If the content isn't HTML, $mech will die.

print "The content is encoded as ", $mech->content_encoding;

Returns the encoding that the content is in. This can be used to convert the content from UTF-8 back to its native encoding.

$mech->update_html($html);

Writes $html into the current document. This is mostly implemented as a convenience method for HTML::Display::MozRepl.

print $mech->base;

Returns the URL base for the current page.

The base is either specified through a base tag or is the current URL.

This method is specific to WWW::Mechanize::PhantomJS.

print $mech->content_type;

Returns the content type of the currently loaded document

print $mech->is_html();

Returns true/false on whether our content is HTML, according to the HTTP headers.

print "We are on page " . $mech->title;

Returns the current document title.

print $_->text . " -> " . $_->url . "\n"
    for $mech->links;

Returns all links in the document as WWW::Mechanize::Link objects.

Currently accepts no parameters. See ->xpath or ->selector when you want more control.

my @text = $mech->selector('p.content');

Returns all nodes matching the given CSS selector. If $css_selector is an array reference, it returns all nodes matched by any of the CSS selectors in the array.

This takes the same options that ->xpath does.

This method is implemented via WWW::Mechanize::Plugin::Selector.

print $_->{innerHTML} . "\n"
    for $mech->find_link_dom( text_contains => 'CPAN' );

A method to find links, like WWW::Mechanize's ->find_links method. This method returns DOM objects from PhantomJS instead of WWW::Mechanize::Link objects.

Note that PhantomJS might have reordered the links or frame links in the document so the absolute numbers passed via n might not be the same between WWW::Mechanize and WWW::Mechanize::PhantomJS.

The supported options are:

• text and text_contains and text_regex

  Match the text of the link as a complete string, substring or regular expression.

  Matching as a complete string or substring is a bit faster, as it is done in the XPath engine of PhantomJS.

• id and id_contains and id_regex

  Matches the id attribute of the link completely or as part

• name and name_contains and name_regex

  Matches the name attribute of the link

• url and url_regex

  Matches the URL attribute of the link (href, src or content).

• class - the class attribute of the link

• n - the (1-based) index. Defaults to returning the first link.

• single - If true, ensure that only one element is found. Otherwise croak or carp, depending on the autodie parameter.

• one - If true, ensure that at least one element is found. Otherwise croak or carp, depending on the autodie parameter.

  The method croaks if no link is found. If the single option is true, it also croaks when more than one link is found.

print $_->text . "\n"
    for $mech->find_link( text_contains => 'CPAN' );

A method quite similar to WWW::Mechanize's method. The options are documented in ->find_link_dom.

Returns a WWW::Mechanize::Link object.

This defaults to not look through child frames.

print $_->text . "\n"
    for $mech->find_all_links( text_regex => qr/google/i );

Finds all links in the document. The options are documented in ->find_link_dom.

Returns them as list or an array reference, depending on context.

This defaults to not look through child frames.

print $_->{innerHTML} . "\n"
    for $mech->find_all_links_dom( text_regex => qr/google/i );

Finds all matching linky DOM nodes in the document. The options are documented in ->find_link_dom.

Returns them as list or an array reference, depending on context.

This defaults to not look through child frames.

$mech->follow_link( xpath => '//a[text() = "Click here!"]' );

Follows the given link. Takes the same parameters that find_link_dom uses.

Note that ->follow_link will only try to follow link-like things like A tags.

my $link = $mech->xpath('//a[id="clickme"]', one => 1);
# croaks if there is no link or more than one link found

my @para = $mech->xpath('//p');
# Collects all paragraphs

my @para_text = $mech->xpath('//p/text()', type => $mech->xpathResult('STRING_TYPE'));
# Collects all paragraphs as text

Runs an XPath query in PhantomJS against the current document.

If you need more information about the returned results, use the ->xpathEx() function.

The options allow the following keys:

• document - document in which the query is to be executed. Use this to search a node within a specific subframe of $mech->document.

• frames - if true, search all documents in all frames and iframes. This may or may not conflict with node. This will default to the frames setting of the WWW::Mechanize::PhantomJS object.

• node - node relative to which the query is to be executed. Note that you will have to use a relative XPath expression as well. Use

    .//foo
  

  instead of

    //foo
  

• single - If true, ensure that only one element is found. Otherwise croak or carp, depending on the autodie parameter.

• one - If true, ensure that at least one element is found. Otherwise croak or carp, depending on the autodie parameter.

• maybe - If true, ensure that at most one element is found. Otherwise croak or carp, depending on the autodie parameter.

• all - If true, return all elements found. This is the default. You can use this option if you want to use ->xpath in scalar context to count the number of matched elements, as it will otherwise emit a warning for each usage in scalar context without any of the above restricting options.

• any - no error is raised, no matter if an item is found or not.

• type - force the return type of the query.

    type => $mech->xpathResult('ORDERED_NODE_SNAPSHOT_TYPE'),
  

  WWW::Mechanize::PhantomJS tries a best effort in giving you the appropriate result of your query, be it a DOM node or a string or a number. In the case you need to restrict the return type, you can pass this in.

  The allowed strings are documented in the MDN. Interesting types are

    ANY_TYPE     (default, uses whatever things the query returns)
    STRING_TYPE
    NUMBER_TYPE
    ORDERED_NODE_SNAPSHOT_TYPE
  

Returns the matched results.

You can pass in a list of queries as an array reference for the first parameter. The result will then be the list of all elements matching any of the queries.

This is a method that is not implemented in WWW::Mechanize.

In the long run, this should go into a general plugin for WWW::Mechanize.

my @text = $mech->by_id('_foo:bar');

Returns all nodes matching the given ids. If $id is an array reference, it returns all nodes matched by any of the ids in the array.

This method is equivalent to calling ->xpath :

$self->xpath(qq{//*[\@id="$_"], %options)

It is convenient when your element ids get mistaken for CSS selectors.

$mech->click( 'go' );
$mech->click({ xpath => '//button[@name="go"]' });

Has the effect of clicking a button (or other element) on the current form. The first argument is the name of the button to be clicked. The second and third arguments (optional) allow you to specify the (x,y) coordinates of the click.

If there is only one button on the form, $mech->click() with no arguments simply clicks that one button.

If you pass in a hash reference instead of a name, the following keys are recognized:

• selector - Find the element to click by the CSS selector

• xpath - Find the element to click by the XPath query

• dom - Click on the passed DOM element

  You can use this to click on arbitrary page elements. There is no convenient way to pass x/y co-ordinates with this method.

• id - Click on the element with the given id

  This is useful if your document ids contain characters that do look like CSS selectors. It is equivalent to

    xpath => qq{//*[\@id="$id"]}
  

Returns a HTTP::Response object.

As a deviation from the WWW::Mechanize API, you can also pass a hash reference as the first parameter. In it, you can specify the parameters to search much like for the find_link calls.

$mech->click_button( name => 'go' );
$mech->click_button( input => $mybutton );

Has the effect of clicking a button on the current form by specifying its name, value, or index. Its arguments are a list of key/value pairs. Only one of name, number, input or value must be specified in the keys.

• name - name of the button
• value - value of the button
• input - DOM node
• id - id of the button
• number - number of the button

If you find yourself wanting to specify a button through its selector or xpath, consider using ->click instead.

print $mech->current_form->{name};

Returns the current form.

This method is incompatible with WWW::Mechanize. It returns the DOM <form> object and not a HTML::Form instance.

The current form will be reset by WWW::Mechanize::PhantomJS on calls to ->get() and ->get_local(), and on calls to ->submit() and ->submit_with_fields.

open my $fh, '>', 'form-log.txt'
    or die "Couldn't open logfile 'form-log.txt': $!";
$mech->dump_forms( $fh );

Prints a dump of the forms on the current page to the filehandle $fh. If $fh is not specified or is undef, it dumps to STDOUT.

$mech->form_name( 'search' );

Selects the current form by its name. The options are identical to those accepted by the "$mech->xpath" method.

$mech->form_id( 'login' );

Selects the current form by its id attribute. The options are identical to those accepted by the "$mech->xpath" method.

This is equivalent to calling

$mech->by_id($id,single => 1,%options)

$mech->form_number( 2 );

Selects the _number_th form. The options are identical to those accepted by the "$mech->xpath" method.

$mech->form_with_fields(
    'user', 'password'
);

Find the form which has the listed fields.

If the first argument is a hash reference, it's taken as options to ->xpath.

See also "$mech->submit_form".

my @forms = $mech->forms();

When called in a list context, returns a list of the forms found in the last fetched page. In a scalar context, returns a reference to an array with those forms.

The options are identical to those accepted by the "$mech->selector" method.

The returned elements are the DOM <form> elements.

$mech->field( user => 'joe' );
$mech->field( not_empty => '', [], [] ); # bypass JS validation

Sets the field with the name given in $selector to the given value. Returns the value.

The method understands very basic CSS selectors in the value for $selector, like the HTML::Form find_input() method.

A selector prefixed with '#' must match the id attribute of the input. A selector prefixed with '.' matches the class attribute. A selector prefixed with '^' or with no prefix matches the name attribute.

By passing the array reference @pre_events, you can indicate which Javascript events you want to be triggered before setting the value. @post_events contains the events you want to be triggered after setting the value.

By default, the events set in the constructor for pre_events and post_events are triggered.

print $mech->value( 'user' );

Returns the value of the field given by $selector_or_name or of the DOM element passed in.

The legacy form of

$mech->value( name => value );

is also still supported but will likely be deprecated in favour of the ->field method.

For fields that can have multiple values, like a select field, the method is context sensitive and returns the first selected value in scalar context and all values in list context.

Allows fine-grained access to getting/setting a value with a different API. Supported keys are:

pre
post
name
value

in addition to all keys that $mech->xpath supports.

$mech->submit;

Submits the form. Note that this does not fire the onClick event and thus also does not fire eventual Javascript handlers. Maybe you want to use $mech->click instead.

The default is to submit the current form as returned by $mech->current_form.

$mech->submit_form(
    with_fields => {
        user => 'me',
        pass => 'secret',
    }
);

This method lets you select a form from the previously fetched page, fill in its fields, and submit it. It combines the form_number/form_name, set_fields and click methods into one higher level call. Its arguments are a list of key/value pairs, all of which are optional.

• form => $mech->current_form()

  Specifies the form to be filled and submitted. Defaults to the current form.

• fields => \%fields

  Specifies the fields to be filled in the current form

• with_fields => \%fields

  Probably all you need for the common case. It combines a smart form selector and data setting in one operation. It selects the first form that contains all fields mentioned in \%fields. This is nice because you don't need to know the name or number of the form to do this.

  (calls "$mech->form_with_fields()" and "$mech->set_fields()").

  If you choose this, the form_number, form_name, form_id and fields options will be ignored.

$mech->set_fields(
    user => 'me',
    pass => 'secret',
);

This method sets multiple fields of the current form. It takes a list of field name and value pairs. If there is more than one field with the same name, the first one found is set. If you want to select which of the duplicate field to set, use a value which is an anonymous array which has the field value and its number as the 2 elements.

my @frames = $mech->expand_frames();

Expands the frame selectors (or 1 to match all frames) into their respective PhantomJS nodes according to the current document. All frames will be visited in breadth first order.

This is mostly an internal method.

my $last_frame= $mech->current_frame;
# Switch frame somewhere else

# Switch back
$mech->activate_container( $last_frame );

Returns the currently active frame as a WebElement.

This is mostly an internal method.

See also

http://code.google.com/p/selenium/issues/detail?id=4305

Frames are currently not really supported.

my $png_data = $mech->content_as_png();

# Create scaled-down 480px wide preview
my $png_data = $mech->content_as_png(undef, { width => 480 });

Returns the given tab or the current page rendered as PNG image.

All parameters are optional.

• \%coordinates

  If the coordinates are given, that rectangle will be cut out. The coordinates should be a hash with the four usual entries, left,top,width,height.

This method is specific to WWW::Mechanize::PhantomJS.

Currently, the data transfer between PhantomJS and Perl is done Base64-encoded.

print Dumper $mech->viewport_size;
$mech->viewport_size({ width => 1388, height => 792 });

Returns (or sets) the new size of the viewport (the "window").

my $shiny = $mech->selector('#shiny', single => 1);
my $i_want_this = $mech->element_as_png($shiny);

Returns PNG image data for a single element

my $shiny = $mech->selector('#shiny', single => 1);
my $i_want_this= $mech->render_element(
    element => $shiny,
    format => 'pdf',
);

Returns the data for a single element or writes it to a file. It accepts all options of ->render_content.

my $shiny = $mech->selector('#shiny', single => 1);
my ($pos) = $mech->element_coordinates($shiny);
print $pos->{left},',', $pos->{top};

Returns the page-coordinates of the $element in pixels as a hash with four entries, left, top, width and height.

This function might get moved into another module more geared towards rendering HTML.

my $pdf_data = $mech->render( format => 'pdf' );

$mech->render_content(
    format => 'jpg',
    filename => '/path/to/my.jpg',
);

Returns the current page rendered in the specified format as a bytestring or stores the current page in the specified filename.

The filename must be absolute. We are dealing with external processes here!

This method is specific to WWW::Mechanize::PhantomJS.

Currently, the data transfer between PhantomJS and Perl is done through a temporary file, so directly using the filename option may be faster.

my $pdf_data = $mech->content_as_pdf();

$mech->content_as_pdf(
    filename => '/path/to/my.pdf',
);

Returns the current page rendered in PDF format as a bytestring.

This method is specific to WWW::Mechanize::PhantomJS.

Currently, the data transfer between PhantomJS and Perl is done through a temporary file, so directly using the filename option may be faster.

These are methods that are available but exist mostly as internal helper methods. Use of these is discouraged.

my $query = $mech->element_query(['input', 'select', 'textarea'],
                           { name => 'foo' });

Returns the XPath query that searches for all elements with tagNames in @elements having the attributes %attributes. The @elements will form an or condition, while the attributes will form an and condition.

Returns the Javascript fragment to turn a Selenium::Remote::PhantomJS id back to a Javascript object.

As this module is in a very early stage of development, there are many incompatibilities. The main thing is that only the most needed WWW::Mechanize methods have been implemented by me so far.

At least the following methods are unsupported:

• ->find_all_inputs

  This function is likely best implemented through $mech->selector.

• ->find_all_submits

  This function is likely best implemented through $mech->selector.

• ->images

  This function is likely best implemented through $mech->selector.

• ->find_image

  This function is likely best implemented through $mech->selector.

• ->find_all_images

  This function is likely best implemented through $mech->selector.

These functions are unlikely to be implemented because they make little sense in the context of PhantomJS.

• ->clone

• ->credentials( $username, $password )

• ->get_basic_credentials( $realm, $uri, $isproxy )

• ->clear_credentials()

• ->put

  I have no use for it

• ->post

  Selenium does not support POST requests

• Add limit parameter to ->xpath() to allow an early exit-case when searching through frames.
