A basic http request lib, able to send GET/POST request and call the corresponding callback after having received all the body data (assume that there's limited data).

Implemented by simply creating a new thread to perform the request and call the callback function.

Default c lib does not have common data structures like String or Map. And I did't implement one myself. So I need to define buf length as an estimated upper bound or write some other compromised code.

Asynchronous I/O suits the requirement best. There are aio functions in linux but I did't use them in the implementation.

First, need to ensure the server is running. You can run HTTP_server or change the domain name in src/HttpRequestDemo.c to some public domain name. Take an example of GET http://www.baidu.com/index.html, baidu did't close the connection after responding. Actually, it's a keep-alive connection and has "Connection: keep-alive" in the response header, so I need to use Content-Length header to tell if the client has received all the data and close the connection in the client side (see MyHttp.c threadRun_get() function), else my client implementation will keep pending.

1.Open HTTP_request folder with VSCode and open src/HttpRequestDemo.c to run.

2.Or

HTTP_request> gcc src/HttpRequestDemo.c lib/MyHttp.c -I include -o src/HttpRequestDemo
HTTP_request> ./src/HttpRequestDemo
