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', request => {
console.log(request.url() + ' ' + request.failure().errorText);
});
Human-readable error message, e.g. 'net::ERR_FAILED'
.
Returns the Frame that initiated this request.
Usage
const frameUrl = request.frame().url();
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:
if (request.serviceWorker())
console.log(`request ${request.url()} from a service worker`);
else if (request.isNavigationRequest())
console.log(`request ${request.url()} is a navigation request`);
else
console.log(`request ${request.url()} from a frame ${request.frame().url()}`);
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.allHeaders() for complete list of
headers that include cookie
information.
An array with all the request HTTP headers associated with this request. Unlike
request.allHeaders(), header names are NOT
lower-cased. Headers with multiple entries, such as Set-Cookie
, appear in the array multiple times.
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.
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
:
const response = await page.goto('http://example.com');
console.log(response.request().redirectedFrom().url()); // 'http://example.com'
If the website https://google.com
has no redirects:
const response = await page.goto('https://google.com');
console.log(response.request().redirectedFrom()); // null
New request issued by the browser if the server responded with redirect.
Usage
This method is the opposite of request.redirectedFrom():
console.log(request.redirectedFrom().redirectedTo() === request); // true
The Service Worker that is performing the request.
Details
This method is Chromium only. It's safe to call when using other browsers, but it will always be null
.
Requests originated in a Service Worker do not have a request.frame() available.
Returns resource size information for given request.
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
const requestFinishedPromise = page.waitForEvent('requestfinished');
await page.goto('http://example.com');
const request = await requestFinishedPromise;
console.log(request.timing());
Time immediately before the user agent starts establishing the connection to the server to retrieve the resource.

Time immediately before the browser starts the domain name lookup for the resource. The value is given in

Time immediately before the browser starts requesting the resource from the server, cache, or local resource. The

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 to startTime
, -1 if not
available.
Time immediately after the browser receives the first byte of the response from the server, cache, or local
resource. The value is given in milliseconds relative to startTime
, -1 if not available.

Generated using TypeDoc
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.
