Request
Whenever the page sends a request for a network resource the following sequence of events are emitted by Page:
- page.on("request") emitted when the request is issued by the page.
- page.on("response") emitted when/if the response status and headers are received for the request.
- page.on("requestfinished") emitted when the response body is downloaded and the request is complete.
If request fails at some point, then instead of 'requestfinished'
event (and possibly instead of 'response' event), the page.on("requestfailed") event is emitted.
note
HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with 'requestfinished'
event.
If request gets a 'redirect' response, the request is successfully finished with the 'requestfinished' event, and a new request is issued to a redirected url.

#
request.failureThe method returns null
unless this request has failed, as reported by requestfailed
event.
Example of logging of all the failed requests:
#
request.frame- returns: <Frame>
Returns the Frame that initiated this request.
#
request.headersAn object with HTTP headers associated with the request. All header names are lower-case.
#
request.is_navigation_request()- returns: <bool>
Whether this request is driving frame's navigation.
#
request.method- returns: <str>
Request's method (GET, POST, etc.)
#
request.post_dataRequest's post body, if any.
#
request.post_data_buffer- returns: <NoneType|[Buffer]>
Request's post body in a binary form, if any.
#
request.post_data_jsonReturns parsed request's body for form-urlencoded
and JSON as a fallback if any.
When the response is application/x-www-form-urlencoded
then a key/value object of the values will be returned. Otherwise it will be parsed as JSON.
#
request.redirected_fromRequest that was redirected by the server to this one, if any.
When the server responds with a redirect, Playwright creates a new Request object. The two requests are connected by redirectedFrom()
and redirectedTo()
methods. When multiple server redirects has happened, it is possible to construct the whole redirect chain by repeatedly calling redirectedFrom()
.
For example, if the website http://example.com
redirects to https://example.com
:
- Sync
- Async
If the website https://google.com
has no redirects:
- Sync
- Async
#
request.redirected_toNew request issued by the browser if the server responded with redirect.
This method is the opposite of request.redirected_from:
#
request.resource_type- returns: <str>
Contains the request's resource type as it was perceived by the rendering engine. ResourceType will be one of the following: document
, stylesheet
, image
, media
, font
, script
, texttrack
, xhr
, fetch
, eventsource
, websocket
, manifest
, other
.
#
request.response()Returns the matching Response object, or null
if the response was not received due to error.
#
request.timing- returns: <Dict>
startTime
<float> Request start time in milliseconds elapsed since January 1, 1970 00:00:00 UTCdomainLookupStart
<float> Time immediately before the browser starts the domain name lookup for the resource. The value is given in milliseconds relative tostartTime
, -1 if not available.domainLookupEnd
<float> Time immediately after the browser starts the domain name lookup for the resource. The value is given in milliseconds relative tostartTime
, -1 if not available.connectStart
<float> Time immediately before the user agent starts establishing the connection to the server to retrieve the resource. The value is given in milliseconds relative tostartTime
, -1 if not available.secureConnectionStart
<float> Time immediately before the browser starts the handshake process to secure the current connection. The value is given in milliseconds relative tostartTime
, -1 if not available.connectEnd
<float> Time immediately before the user agent starts establishing the connection to the server to retrieve the resource. The value is given in milliseconds relative tostartTime
, -1 if not available.requestStart
<float> Time immediately before the browser starts requesting the resource from the server, cache, or local resource. The value is given in milliseconds relative tostartTime
, -1 if not available.responseStart
<float> Time immediately after the browser starts requesting the resource from the server, cache, or local resource. The value is given in milliseconds relative tostartTime
, -1 if not available.responseEnd
<float> Time immediately after the browser receives the last byte of the resource or immediately before the transport connection is closed, whichever comes first. The value is given in milliseconds relative tostartTime
, -1 if not available.
Returns resource timing information for given request. Most of the timing values become available upon the response, responseEnd
becomes available when request finishes. Find more information at Resource Timing API.

request.url- returns: <str>
URL of the request.
