该程序用于实现实现了GET请求的Web服务器程序的方法，通过创建ServerSocket类对象，监听端口8080； 等待、接受客户机连接到端口8080； 创建与socket字相关联的输入流和输出流 然后，读取客户机的请求信息，若请求类型是GET，则从请求信息中获取所访问的HTML文件名，如果HTML文件存在，则打开HTML文件，把HTTP头信息和HTML文件内容通过socket传回给Web浏览器，然后关闭文件。否则发送错误信息给Web浏览器。最后，关闭与相应Web浏览器连接的socket字。 -The program used to implement to achieve the GET request method of Web server program, by creating ServerSocket class object, monitor port 8080　waiting to receive client connections to port 8080　create a word associated with the socket input stream and output stream　then , read the client request information, if the request type is GET, request information from the visit to get the HTML file name, if the HTML file exists, then open the HTML file, the HTTP header information and the HTML file content returned by socket to the Web browser, then close the file. Otherwise, an error message sent to Web browser. Finally, close the Web browser with the corresponding socket connection word.
