Asynchronously invoke this but expect a continuous stream of content.
This means that the body data will not be accumulated and thus you cannot use get_payload
When there is data callback will be called and when the connection is closed or the stream ends callback will
also be called.
If weak_object is disposed during the call then this call will be cancelled. If the call is cancelled then the callback will
be invoked with an error state.
You may unref the call after calling this function since there is an internal reference, or you may unref in the callback.
