java - 使用 Java 连接到 Socket 服务器发送 header

Question

我想在 Java 套接字中打开连接时发送 header 。是否可以？我必须使用 Java EE 的 WebSockets 吗？

Answer 1

你能发布你的代码吗？另外您想发送什么 header ？你必须准确解释你想做什么

类似这样的吗？

    try
    {
        Socket  s = new Socket ();
        s.bind    (new InetSocketAddress (ipFrom, 0));
        s.connect (new InetSocketAddress (ipTo,   80), 1000);

        PrintWriter     writer = new PrintWriter    (s.getOutputStream ());
        BufferedReader  reader = new BufferedReader (new InputStreamReader (s.getInputStream ()));

    writer.print ("GET " + szUrl + " HTTP/1.0\r\n"); 
//Also you can send multiple headers like this

    writer.print ("header1: value1\r\n"); 
    writer.print ("header2: value2\r\n"); 
    writer.print ("header3: value3\r\n"); 

// end the header section
writer.print ("\r\n"); 
        writer.flush ();

        s     .close ();
        reader.close ();
        writer.close ();
    }
