Chrome-har
Create HAR files based on Chrome DevTools Protocol data.
Code originally extracted from Browsertime, initial implementation inspired by Chromedriver_har.
Create a new bug report
Make sure to generate a event trace log file that we can use to recreate your issue. If you use Browsertime you can enable the trace with --chrome.collectPerfLog
:
$ browsertime --chrome.collectPerfLog -n 1 https://www.sitespeed.io
Then take the file named chromePerflog-1.json.gz and put it in a gist or make it availible to us in any way you want.
If you use sitespeed.io:
$ sitespeed.io --browsertime.chrome.collectPerfLog -n 1 https://www.sitespeed.io
Support for Response Bodies
If you use Chrome-har standalone (without Browsertime/sitespeed.io) you can use get the response bodies in HARs if they are set on the response object by the caller and if the includeTextFromResponseBody
option is set to true
.
For example:
const harEvents: Array<any> = [];
client.on('Network.requestIntercepted', async (params: any) => {
// Get the response body
const response = await client.send(
'Network.getResponseBodyForInterception',
{ interceptionId: params.interceptionId },
);
// Set the body on the response object
if (params.response != null) {
params.response.body = response.body;
} else {
params.response = response;
}
// Continue the request
await client.send(
'Network.continueInterceptedRequest',
{ interceptionId: params.interceptionId },
);
harEvents.push({ method, params });
});
const har = harFromMessages(harEvents, {includeTextFromResponseBody: true});
