On this page
Whenever the page sends a request for a network resource the following sequence of events are emitted by Page :
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.
Methods
Added in: v1.15 request.all_headers
An object with all the request HTTP headers associated with this request. The header names are lower-cased.
Usage
request.all_headers()
Returns
Added in: v1.15 request.header_value
Returns the value of the header matching the name. The name is case-insensitive.
Usage
request.header_value(name)
Arguments
Returns
Added in: v1.15 request.headers_array
An array with all the request HTTP headers associated with this request. Unlike request.all_headers()
, header names are NOT lower-cased. Headers with multiple entries, such as Set-Cookie, appear in the array multiple times.
Usage
request.headers_array()
Returns
Added before v1.9 request.response
Returns the matching Response
object, or null if the response was not received due to error.
Usage
request.response()
Returns
Added in: v1.15 request.sizes
Returns resource size information for given request.
Usage
request.sizes()
Returns
requestBodySize int
Size of the request body (POST data payload) in bytes. Set to 0 if there was no body.
requestHeadersSize int
Total number of bytes from the start of the HTTP request message until (and including) the double CRLF before the body.
responseBodySize int
Size of the received response body (encoded) in bytes.
responseHeadersSize int
Total number of bytes from the start of the HTTP response message until (and including) the double CRLF before the body.
Properties
Added before v1.9 request.failure
The method returns null unless this request has failed, as reported by requestfailed event.
Usage
Example of logging of all the failed requests:
page.on("requestfailed", lambda request: print(request.url + " " + request.failure))
Returns
Added before v1.9 request.frame
Returns the Frame that initiated this request.
Usage
frame_url = request.frame.url
Returns
Details
Note that in some cases the frame is not available, and this method will throw.
request.serviceWorker() to check that.Here is an example that handles all the cases:
Added before v1.9 request.headers
An object with the request HTTP headers. The header names are lower-cased. Note that this method does not return security-related headers, including cookie-related ones. You can use request.all_headers()
for complete list of headers that include cookie information.
Usage
request.headers
Returns
Added before v1.9 request.is_navigation_request
Whether this request is driving frame's navigation.
Some navigation requests are issued before the corresponding frame is created, and therefore do not have request.frame available.
Usage
request.is_navigation_request()
Returns
Added before v1.9 request.method
Request's method (GET, POST, etc.)
Usage
request.method
Returns
Added before v1.9 request.post_data
Request's post body, if any.
Usage
request.post_data
Returns
Added before v1.9 request.post_data_buffer
Request's post body in a binary form, if any.
Usage
request.post_data_buffer
Returns
Added before v1.9 request.post_data_json
Returns 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.
Usage
request.post_data_json
Returns
Added before v1.9 request.redirected_from
Request 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().
Usage
For example, if the website http://example.com redirects to https://example.com:
Sync
Async
response = page.goto("http://example.com")print(response.request.redirected_from.url) # "http://example.com"
response = await page.goto("http://example.com")print(response.request.redirected_from.url) # "http://example.com"
If the website https://google.com has no redirects:
Sync
Async
response = page.goto("https://google.com")print(response.request.redirected_from) # None
response = await page.goto("https://google.com")print(response.request.redirected_from) # None
Returns
Added before v1.9 request.redirected_to
New request issued by the browser if the server responded with redirect.
Usage
This method is the opposite of request.redirected_from :
assert request.redirected_from.redirected_to == request
Returns
Added before v1.9 request.resource_type
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.
Usage
request.resource_type
Returns
Added before v1.9 request.timing
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
.
Usage
Sync
Async
with page.expect_event("requestfinished") as request_info: page.goto("http://example.com")request = request_info.valueprint(request.timing)
async with page.expect_event("requestfinished") as request_info: await page.goto("http://example.com")request = await request_info.valueprint(request.timing)
Returns
startTime float
Request start time in milliseconds elapsed since January 1, 1970 00:00:00 UTC
domainLookupStart float
Time immediately before the browser starts the domain name lookup for the resource. The value is given in milliseconds relative to startTime, -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 to startTime, -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 to startTime, -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 to startTime, -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 to startTime, -1 if not available.
