Compared to the traditional JDK urlconnection, it adds ease of use and flexibility (specifically, we'll discuss later), not only is it easier for clients to send HTTP requests, It also facilitates the developer testing interface (based on HTTP protocol), which improves the efficiency of the development and facilitates the robustness of the code. Therefore, the mastery of httpclient is very important compulsory content, Mas
