The google.appengine.api.urlfetch
package provides the following function:
Fetches a document at the URL given in url, and returns an object containing the details of the response. See Response Objects for details about the return value.
Arguments:
http
or https
URL. If the URL is invalid, a InvalidURLError is raised.POST
or PUT
request.GET
, POST
, HEAD
, PUT
, and DELETE
. These values are constants provided by the package.False
and the response data exceeds the maximum allowed response size, a ResponseTooLargeError exception is raised. If True
, no exception is raised, and the response's content
is truncated to the maximum size, and the response object's content_was_truncated
attribute is set to True
. If True
, responses that are HTTP redirects are followed, up to 5 consecutive redirects. The response data is from the final location, as if the data were for the requested location. If False
, redirects are not followed, and a redirect response is returned directly to the application, including the header information that describes the redirect.
Warning: Cookies are not handled upon redirection. If cookie handling is needed, set follow_redirects to False
and handle both cookies and redirects manually.
The fetch action is synchronous. fetch()
will not return until the server responds. A slow remote server may cause your application's own request to time out.
Note: URL fetching cannot authenticate the server of an https
request because there is no certificate trust chain. The proxy accepts all certificates, including self-signed certificates.
For security reasons, the following HTTP headers for outbound HTTP requests cannot be modified by the application.
Content-Length
