Question

我正在使用套接字来创建给定服务器的POST请求。响应大部分都回来了，我正在使用编码为“UTF-8”的InputStream来读取服务器的响应。大多数响应是有道理的，我能够正确地查看HTML，但是，看似随机，我看到“1ffa”，“6e8”，“1972”，“90”，“0”等代码出现我正在读它的响应单行。这是我创建和阅读响应的方式。

    String hostname = "server";
    SocketFactory socketFactory = SSLSocketFactory.getDefault();
    Socket socket = new Socket(hostname, 8080);
   // Create streams to securely send and receive data to the server
    InputStream in = socket.getInputStream();
    OutputStream out = socket.getOutputStream();
    PrintWriter writer = new PrintWriter(out);
    writer.println("POST /handlerServlet http/1.1");
    writer.println("Host: " + hostname);
    String parameters="params=" + URLEncoder.encode("paramsToEncode", "UTF-8"); 
    writer.println("Content-Length: " + parameters.length());
    writer.println("Content-Type: application/x-www-form-urlencoded");
    writer.println("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
    writer.println("Keep-Alive: 115");
    writer.println("Connection: keep-alive");
    writer.println("\r\n" + parameters + "\r\n");
    writer.flush();
    // Read from in and write to out...
    String input = "";
    BufferedReader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"));
    StringBuffer result = new StringBuffer();
    boolean startWriting = false;
    FileOutputStream outStream1 = new FileOutputStream(new File("/file1.txt"));
    Writer outWriter = new OutputStreamWriter(outStream1, "UTF-8");

    while ( (input = reader.readLine()) != null) {
    result.append(input);
    outWriter.write(input + "\n");
    result.append('\n');
    }
    System.out.println(result.toString());
    outWriter.close();
    // Close the socket
    in.close();

有没有人知道为什么我会看到这样的人物？

正如您所看到的，让这些字符出现在随机位置会导致HTML代码出现一些麻烦行为。

感谢。

你的回复中是否有一个标题是这样的？

Transfer-Encoding: chunked

在这种情况下，最有可能是HTTP Chunked Transfer Encoding。这很正常。

使用套接字的HTTP响应上的随机字符
