Question

我有一个小测试应用程序：

Socket socket = new Socket("jeck.ru", 80);

PrintWriter pw = new PrintWriter(socket.getOutputStream(), false);
pw.println("GET /ip/ HTTP/1.1");
pw.println("Host: jeck.ru");
pw.println();
pw.flush();

BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));

String str;
while ((str = rd.readLine()) != null) {
    System.out.println(str);
}

它的输出：

HTTP/1.1 200 OK

Content-Type: text/html;charset=utf-8
Transfer-Encoding: chunked
