带有套接字的Couchdb http POST请求

Question

我试图使用套接字向couchdb发出POST请求，但它没有工作，我没有得到任何响应，程序也没有结束。怎么了？

Socket socket = new Socket("127.0.0.1",5984);
    BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF8"));
    wr.write("POST /meteo/ HTTP/1.0\r\n");
    wr.write("Content-Length: 245\r\n");
    wr.write("Content-Type: application/json\r\n");
    wr.write("\r\n");

    wr.write(json.toString());//json is a JsonObject
    wr.flush();

    BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
       String line;
       while ((line = rd.readLine()) != null) {
         System.out.println(line);
       }
    wr.close();
    rd.close();

}
