flask.Flask.preprocess_request¶
-
Flask.
preprocess_request
()[source]¶ Called before the actual request dispatching and will call each
before_request()
decorated function, passing no arguments. If any of these functions returns a value, it’s handled as if it was the return value from the view and further request handling is stopped.This also triggers the
url_value_processor()
functions before the actualbefore_request()
functions are called.
