Method fetch

tornado/httpclient.py:122–137

Executes a request, returning an `HTTPResponse`. The request may be either a string URL or an `HTTPRequest` object. If it is a string, we construct an `HTTPRequest` using any additional kwargs: ``HTTPRequest(request, **kwargs)`` If an error occurs during the fetch,

(
        self, request: Union["HTTPRequest", str], **kwargs: Any
    )

            self._closed = True

    def fetch(
        self, request: Union["HTTPRequest", str], **kwargs: Any
    ) -> "HTTPResponse":
