: This article mainly introduces the http get and post encapsulation of the Weibo development 1 client. For more information about PHP tutorials, see. This blog is about how the client encapsulates the Http protocol, and how the client uses the post and get methods, which is one of the core code.
The following is an excerpt from Huangshi Jun's android and PHP development.
