我正在编写一个简单的程序来向特定网址发送get请求 badunetworks/about / 。如果我将其发送到 badunetworks ，请求仍然有效，但我需要将其发送到关于页面。

I am writing a simple program to send a get request to a specific url "badunetworks/about/". The request works if I send it to "badunetworks" but I need to send it to the about page.

package badunetworks; import java.io.*; import java.*; public class GetRequest { public static void main(String[] args) throws Exception { GetRequest getReq = new GetRequest(); //Runs SendReq passing in the url and port from the command line getReq.SendReq("www.badunetworks/about/", 80); } public void SendReq(String url, int port) throws Exception { //Instantiate a new socket Socket s = new Socket("www.badunetworks/about/", port); //Instantiates a new PrintWriter passing in the sockets output stream PrintWriter wtr = new PrintWriter(s.getOutputStream()); //Prints the request string to the output stream wtr.println("GET / HTTP/1.1"); wtr.println("Host: www.badunetworks"); wtr.println(""); wtr.flush(); //Creates a BufferedReader that contains the server response BufferedReader bufRead = new BufferedReader(new InputStreamReader(s.getInputStream())); String outStr; //Prints each line of the response while((outStr = bufRead.readLine()) != null){ System.out.println(outStr); } //Closes out buffer and writer bufRead.close(); wtr.close(); } }

推荐答案

如果about页面链接是about.html，那么你已将此行wtr.println（GET / HTTP / 1.1）更改为wtr.println（GET /about.html HTTP / 1.1） ）。

if the about page link is about.html ,then you have change this line wtr.println("GET / HTTP/1.1") into wtr.println("GET /about.html HTTP/1.1").

在套接字创建中删除/ about

in socket creation remove the /about

wtr.println（GET / HTTP / 1.1 ）; --->此行调用您指定的主机的主页。

wtr.println("GET / HTTP/1.1");--->this line call the home page of the host you specified.
