For performance reasons, each enabled middleware is initialized only once per server process. That is, __init__() is called only when the server process starts, and is not executed while handling an individual request. For a middleware, the usual reason to define an __init__() method is to check whether it is needed at all.WeChat Official AccountDjangoPythonMiddlewareR&DLearningRequest HandlingArchitecture
