url 
This is a library that makes working with URLs in Clojure and ClojureScript a little more pleasant.
"Installation"
url is available in Clojars. Add this :dependency to your Leiningen
project.clj:
[com.cemerick/url "0.1.1"]Or, add this to your Maven project's pom.xml:
<repository>
<id>clojars</id>
<url>http://clojars.org/repo</url>
</repository>
<dependency>
<groupId>com.cemerick</groupId>
<artifactId>url</artifactId>
<version>0.1.1</version>
</dependency>Starting with version 0.1.0, url requires Clojure >= 1.5.0. It provides the
same API under ClojureScript (tested with ClojureScript 0.0-1835, and should
work well with any later revision).
Usage
The cemerick.url/url function returns an instance of the
cemerick.url.URL record type that allows you to easily work with each
datum within the provided URL:
=> (require '[cemerick.url :refer (url url-encode)])
nil
=> (-> (url "https://api.stripe.com/v1/charges")
(assoc :username "vtUQeOtUnYr7PGCLQ96Ul4zqpDUO4sOE")
str)
"https://vtUQeOtUnYr7PGCLQ96Ul4zqpDUO4sOE:@api.stripe.com/v1/charges"url will also accept additional paths to be resolved against the path
in the base URL:
=> (url "https://api.twitter.com/")
#cemerick.url.URL{:protocol "https", :username nil, :password nil,
:host "api.twitter.com", :port -1, :path "/", :query nil,
:anchor nil}
=> (url "https://api.twitter.com/" "1" "users" "profile_image" "cemerick")
#cemerick.url.URL{:protocol "https", :username nil, :password nil,
:host "api.twitter.com", :port -1,
:path "/1/users/profile_image/cemerick", :query nil, :anchor nil}
=> (str *1)
"https://api.twitter.com/1/users/profile_image/cemerick"
=> (str (url "https://api.twitter.com/1/users/profile_image/cemerick" "../../lookup.json"))
"https://api.twitter.com/1/users/lookup.json"The :query slot can be a string or a map of params:
=> (str (assoc *3 :query {:a 5 :b 6}))
"https://api.twitter.com/1/users/profile_image/cemerick?a=5&b=6"Note that url does not perform any url-encoding of paths. Use
cemerick.url/url-encode to url-encode any paths/path components prior
to passing them to url. e.g.:
=> (def download-root "http://foo.com/dl")
#'cemerick.test-url/download-root
=> (str (url download-root "/"))
"http://foo.com/"
=> (str (url download-root (url-encode "/")))
"http://foo.com/dl/%2F"
=> (str (url download-root (url-encode "/logical/file/path")))
"http://foo.com/dl/%2Flogical%2Ffile%2Fpath"Need Help?
