熟悉Http协议的请求和响应格式，编写一个简单的Http服务器。 基本要求： 1 正确解析Http请求，实现简单的GET请求回应。 2 模拟一个对象（如：文件index.html）的GET回应（如：回应一个字符串），对于其他的对象，则根据Http响应格式回应对象不存在信息。 3 通过浏览器可检测自己的程序。如：输入http://the.ip.of.your.pc:serverPort/index.html，查看其响应结果。 4 对http请求的处理必须采用多进程实现，即主进程负责等待请求连接，每当收到一个请求后，产生一个子进程对该请求做单独处理，主进程继续等待新请求，子进程在处理完其请求后结束自己。详细要求参考课本要求。（多进程编程参考函数fork()） -Http familiar with the agreement of the request and response format, write a simple Http server. Basic requirements: Http parsing a proper request, to achieve a simple GET request to respond. 2 analog an object (such as: file index.html) of the GET response (such as: in response to a string), for other objects, then according to Http response format, the information to respond to the object does not exist. 3 can be detected through the browser s own procedures. Such as: Enter http://the.ip.of.your.pc:serverPort/index.html, see the results of its response. 4 pairs of http request processing must be used to achieve multi-process
