请问这样向服务器发送请求有什么错

public void Request(final String Strjson) throws IOException {

    new Thread(new Runnable() {
        @Override
        public void run() {
            OkHttpClient client = new OkHttpClient();
            MediaType JSON = MediaType.parse("application/json; charset=utf-8");
            RequestBody body = RequestBody.create(JSON, Strjson);
            Log.i("Json",Strjson);
            Request request = new Request.Builder()
                    .url(url)
                    .post(body)
                    .build();
            Response response = null;

            try {
                response = client.newCall(request).execute();
                //String result = response.body().string();

            } catch (IOException e) {

            }
        }
    }).start();
}

    服务端得不到请求的值，也没有报错

把你的服务端代码也贴出来吧，怀疑是服务端接收的方式不对。
