为什么Chrome不从套接字输出流渲染它获得的页面?爪哇

这是我的代码：

import java.net.*;
import java.io.*;
class Server
{
     public static void main(String args[])
     {
          try
          {
                ServerSocket svr = new ServerSocket(8900);
                System.out.println("waiting for request");
                Socket s = svr.accept();
                System.out.println("got a request");
                InputStream in = s.getInputStream();
                OutputStream out = s.getOutputStream();
                int x;
                byte data[]= new byte[1024];
                x = in.read(data);
                String response  = "<html><head><title>HTML content via java socket</title></head><body><h2>Hi! Every Body.</h2></body></html>";
                out.write(response.getBytes());
                out.flush();
                s.close();
                svr.close();
                System.out.println("closing all");
          }
          catch(Exception ex)
          {
                System.out.println("Err : " + ex);
          }
     }
}

运行它，我希望能转到Chrome：127.0.0.1:8900并看起来很漂亮的HTML，但实际上Chrome在说以下内容：

This page isn’t working 127.0.0.1 sent an invalid response. ERR_INVALID_HTTP_RESPONSE。

我的Server.java正在按照我的意愿运行。Eclipse中的控制台在连接后很好地说：

waiting for request got a request closing all。

所以我很卡住。请帮助我弄清楚。

您正在编写的响应肯定是Chrome不可读的。因为它不包含有关标题中响应的任何信息

您的代码实际上是发送响应的。您可以使用curl检查它。以下代码将帮助您在Chrome中获取响应。

        ServerSocket svr = new ServerSocket(8900);
        System.out.println("waiting for request");
        Socket s = svr.accept();
        System.out.println("got a request");
        InputStream in = s.getInputStream();
        OutputStream out = s.getOutputStream();
        int x;
        byte data[] = new byte[1024];
        x = in.read(data);
        String t = "HTTP/1.1 200 OKrn";
        byte[] bb = t.getBytes("UTF-8");
        out.write(bb);
        t = "Content-Length: 124rn";
        bb = t.getBytes("UTF-8");
        out.write(bb);
        t = "Content-Type: text/htmlrnrn";
        bb = t.getBytes("UTF-8");
        out.write(bb);
        String response = "<html><head><title>HTML content via java socket</title></head><body><h2>Hi! Every Body.</h2></body></html>";
        out.write(response.getBytes("UTF-8"));
        t = "Connection: Closed";
        bb = t.getBytes("UTF-8");
        out.write(bb);
        out.flush();
        s.close();
        svr.close();
        System.out.println("closing all");

如果更改response，则必须计算Content-Length:，因为它将是您的response字节的长度[]和Connection: Closed字符串的字节[]。
