使用Java套接字获取GET请求 [英] GET request with Java sockets

问题描述

我正在编写一个简单的程序来向特定网址发送get请求 http://badunetworks.com/about / 。如果我将其发送到 http://badunetworks.com ，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 "http://badunetworks.com/about/". The request works if I send it to "http://badunetworks.com" but I need to send it to the about page.

package badunetworks;
import java.io.*;
import java.net.*;

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.com/about/", 80);


    }

    public void SendReq(String url, int port) throws Exception {

        //Instantiate a new socket
        Socket s = new Socket("www.badunetworks.com/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.com");
        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.
