Method fetch

playwright/async_api/_generated.py:793–863

Route.fetch Performs the request and fetches result without fulfilling it, so that the response could be modified and then fulfilled. **Usage** ```py async def handle(route): response = await route.fetch() json = await response.json(

(
        self,
        *,
        url: typing.Optional[str] = None,
        method: typing.Optional[str] = None,
        headers: typing.Optional[typing.Dict[str, str]] = None,
        post_data: typing.Optional[typing.Union[typing.Any, str, bytes]] = None,
        max_redirects: typing.Optional[int] = None,
        max_retries: typing.Optional[int] = None,
        timeout: typing.Optional[typing.Union[float, datetime.timedelta]] = None,
    )

        )

    async def fetch(
        self,
        *,
        url: typing.Optional[str] = None,
        method: typing.Optional[str] = None,
        headers: typing.Optional[typing.Dict[str, str]] = None,
        post_data: typing.Optional[typing.Union[typing.Any, str, bytes]] = None,
        max_redirects: typing.Optional[int] = None,
        max_retries: typing.Optional[int] = None,
        timeout: typing.Optional[typing.Union[float, datetime.timedelta]] = None,
    ) -> "APIResponse":
        """Route.fetch

        Performs the request and fetches result without fulfilling it, so that the response could be modified and then
        fulfilled.

        **Usage**

        ```py
        async def handle(route):
            response = await route.fetch()
            json = await response.json()
            json[\"message\"][\"big_red_dog\"] = []
            await route.fulfill(response=response, json=json)

        await page.route(\"https://dog.ceo/api/breeds/list/all\", handle)
        ```

        **Details**

        Note that `headers` option will apply to the fetched request as well as any redirects initiated by it. If you want
        to only apply `headers` to the original request, but not to redirects, look into `route.continue_()`
        instead.

        Parameters
        ----------
        url : Union[str, None]
            If set changes the request URL. New URL must have same protocol as original one.
        method : Union[str, None]
            If set changes the request method (e.g. GET or POST).
        headers : Union[Dict[str, str], None]
            If set changes the request HTTP headers. Header values will be converted to a string.
        post_data : Union[Any, bytes, str, None]
            Allows to set post data of the request. If the data parameter is an object, it will be serialized to json string
            and `content-type` header will be set to `application/json` if not explicitly set. Otherwise the `content-type`
            header will be set to `application/octet-stream` if not explicitly set.
        max_redirects : Union[int, None]
            Maximum number of request redirects that will be followed automatically. An error will be thrown if the number is
            exceeded. Defaults to `20`. Pass `0` to not follow redirects.
        max_retries : Union[int, None]
            Maximum number of times network errors should be retried. Currently only `ECONNRESET` error is retried. Does not
            retry based on HTTP response codes. An error will be thrown if the limit is exceeded. Defaults to `0` - no retries.
        timeout : Union[float, None]
            Request timeout in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout.

        Returns
