View Source Playwright.Request (playwright v1.44.0-alpha.4)
Playwright.Request
represents a request for a network resource.
Whenever the page sends a request for a network resource, the following sequence of events are emitted by
Playwright.Page
:
Playwright.Page.on/3
for "request": emitted when the request is issued by the page.Playwright.Page.on/3
for "response": emitted when/if the response status and headers are received for the request.Playwright.Page.on/3
for "requestFinished": emitted when the response body is downloaded and the request is complete.
If the request fails at some point, instead of a "requestFinished" event (and possibly "response" as well),
the Playwright.Page.on/3
for "requestFailed" is emitted.
NOTE
HTTP error responses, such as 404 or 503, are still successful responses from an HTTP stanpoint. So, such requests will complete with a "requestFinished" event.
If a request gets a "redirect" response, the request is successfully finished with the "requestFinished" event, and a new request is issued to the target redirected URL.

Types
@type t() :: %Playwright.Request{ failure: term(), frame: term(), guid: term(), headers: term(), initializer: term(), is_navigation_request: term(), listeners: term(), method: term(), parent: term(), post_data: term(), post_data_buffer: term(), post_data_json: term(), redirected_from: term(), redirected_to: term(), resource_type: term(), session: term(), timing: term(), type: term(), url: term() }

Functions
Optional callback implementation for Playwright.SDK.ChannelOwner.init/2
.
If implemented, the callback will receive:
- The newly created "channel owner" struct.
- The
:initializer
received from the Playwright browser server.
The implementation has the option of "patching" the struct as stored in the catalog, and/or binding event handlers.
Example
def init(%{session: session} = owner, _initializer) do
Channel.bind(session, {:guid, owner.guid}, :close, fn event ->
Logger.warning("Closing #{inspect(event.target)}")
end)
{:ok, %{owner | version: "1.2.3"}}
end
Returns
{:ok, struct()}
Arguments
key/name | type | description | |
---|---|---|---|
owner | param | struct() | The newly created channel owner (resource). |
initializer | param | struct() | The initializer received from with the channel owner instance was derived. |
