- Inherits:
-
PlaywrightApi
- Object
- PlaywrightApi
- Playwright::Request
- Defined in:
- lib/playwright_api/request.rb
Overview
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.

Instance Method Details
#failure ⇒ Object
The method returns ‘null` unless this request has failed, as reported by `requestfailed` event.
Example of logging of all the failed requests:
“‘js page.on(’requestfailed’, request =>
console.log(request.url() + ' ' + request.failure().errorText);
); “‘
“‘py page.on(“requestfailed”, lambda request: print(request.url + “ ” + request.failure)) “`

#post_data_json ⇒ Object
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 ⇒ Object
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()`.
For example, if the website ‘example.com` redirects to `example.com`:
“‘js const response = await page.goto(’example.com’); console.log(response.request().redirectedFrom().url()); // ‘example.com’ “‘
“‘python async response = await page.goto(“example.com”) print(response.request.redirected_from.url) # “example.com” “`
“‘python sync response = page.goto(“example.com”) print(response.request.redirected_from.url) # “example.com” “`
If the website ‘google.com` has no redirects:
“‘js const response = await page.goto(’google.com’); console.log(response.request().redirectedFrom()); // null “‘
“‘python async response = await page.goto(“google.com”) print(response.request.redirected_from) # None “`
“‘python sync response = page.goto(“google.com”) print(response.request.redirected_from) # None “`
114 115 116 |
# File 'lib/playwright_api/request.rb', line 114 def redirected_from wrap_impl(@impl.redirected_from) end |
#redirected_to ⇒ Object
New request issued by the browser if the server responded with redirect.
This method is the opposite of [‘method: Request.redirectedFrom`]:
“‘js console.log(request.redirectedFrom().redirectedTo() === request); // true “`
“‘py assert request.redirected_from.redirected_to == request “`

# File 'lib/playwright_api/request.rb', line 130 def redirected_to wrap_impl(@impl.redirected_to) end |
#resource_type ⇒ Object
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`.

# File 'lib/playwright_api/request.rb', line 137 def resource_type wrap_impl(@impl.resource_type) end |
#response ⇒ Object
Returns the matching ‘Response` object, or `null` if the response was not received due to error.
142 143 144 |
# File 'lib/playwright_api/request.rb', line 142 def response wrap_impl(@impl.response) end |
#timing ⇒ Object
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](developer.mozilla.org/en-US/docs/Web/API/PerformanceResourceTiming).
“‘js const [request] = await Promise.all([
page.waitForEvent('requestfinished'),
page.goto('http://example.com')
]); console.log(request.timing()); “‘
“‘python async async with page.expect_event(“requestfinished”) as request_info:
await page.goto("http://example.com")
request = await request_info.value print(request.timing) “‘
“‘python sync with page.expect_event(“requestfinished”) as request_info:
page.goto("http://example.com")
request = request_info.value print(request.timing) “‘
