java.net.UnknownHostException : http://localhost:8082/consume/create

Question

我正在尝试向服务器发送 http post，但在这行代码中收到 java.net.UnknownHostException

Socket socket = new Socket(REST_SERVICE_URI, 8082);

这是接收请求的 Controller

@RequestMapping(value="AddService",method = RequestMethod.POST)
@ResponseBody
 public void addService(@ModelAttribute("servDetForm") xxxx tb) throws IOException{
    //return dataServices.addService(tb);

     Socket socket = new Socket(REST_SERVICE_URI, 8082);
     String request = "GET / HTTP/1.0\r\n\r\n";
     OutputStream os = socket.getOutputStream();
     os.write(request.getBytes());
     os.flush();

     InputStream is = socket.getInputStream();
     int ch;
     while( (ch=is.read())!= -1)
         System.out.print((char)ch);
     socket.close(); 
 }

请问我哪里错了？

Answer 1

您应该使用 URL 类，而不是使用 Socket 类。套接字需要一个主机名，例如 localhost。它不理解 URL

URL url = new URL(REST_SERVICE_URI);
Object content = url.getContent();
