Request
Whenever the page sends a request for a network resource the following sequence of events are emitted by Page:
- [
event: Page.request
] emitted when the request is issued by the page. - [
event: Page.response
] emitted when/if the response status and headers are received for the request. - [
event: Page.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 [event: Page.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.
all_headers
def all_headers
An object with all the request HTTP headers associated with this request. The header names are lower-cased.
failure
def failure
The method returns null
unless this request has failed, as reported by requestfailed
event.
Example of logging of all the failed requests:
page.on("requestfailed", ->(request) { puts "#{request.url} #{request.failure}" })
frame
def frame
Returns the Frame that initiated this request.
headers
def 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.
headers_array
def 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.
header_value
def header_value(name)
Returns the value of the header matching the name. The name is case insensitive.
navigation_request?
def navigation_request?
Whether this request is driving frame's navigation.
method
def method
Request's method (GET, POST, etc.)
post_data
def post_data
Request's post body, if any.
post_data_buffer
def post_data_buffer
Request's post body in a binary form, if any.
post_data_json
def 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.
redirected_from
def 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 redirected_from and redirected_to methods. When multiple server redirects has happened, it is possible to construct the whole redirect chain by repeatedly calling redirected_from.
For example, if the website http://github.com
redirects to https://github.com
:
response = page.goto("http://github.com")
puts response.url # => "https://github.com"
puts response.request.redirected_from&.url # => "http://github.com"
If the website https://google.com
has no redirects:
response = page.goto("https://google.com")
puts response.request.redirected_from&.url # => nil
redirected_to
def redirected_to
New request issued by the browser if the server responded with redirect.
This method is the opposite of Request#redirected_from:
request.redirected_from.redirected_to # equals to request
resource_type
def 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
.
response
def response
Returns the matching Response object, or null
if the response was not received due to error.
sizes
def sizes
Returns resource size information for given request.
timing
def 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.
request = page.expect_event("requestfinished") do
page.goto("https://example.com")
end
puts request.timing
url
def url
URL of the request.
