无法通过 Android 应用程序插入 azure

我正在为我的应用程序进行登录注册，我必须将它们与 microsoft azure 集成在一起。然而，尽管遵循了 microsoft azure 提供的教程，我仍然无法将我的“字符串”插入他们的数据库。代码中也没有错误，因此我不太确定哪里出了问题。下面是我的代码。

}
}

这是一个代码片段，希望对您有所帮助。

1）承载http get服务的函数

   private String SendDataFromAndroidDevice() {
    String result = "";

    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpGet getMethod = new HttpGet("your url + data appended");

        BufferedReader in = null;
        BasicHttpResponse httpResponse = (BasicHttpResponse) httpclient
                .execute(getMethod);
        in = new BufferedReader(new InputStreamReader(httpResponse
                .getEntity().getContent()));

        StringBuffer sb = new StringBuffer("");
        String line = "";
        while ((line = in.readLine()) != null) {
            sb.append(line);
        }
        in.close();
        result = sb.toString(); 


    } catch (Exception e) {
        e.printStackTrace();
    }
    return result;
}

2）扩展AsyncTask的类

   private class HTTPdemo extends
        AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {}

    @Override
    protected String doInBackground(String... params) {
        String result = SendDataFromAndroidDevice();
        return result;
    }

    @Override
    protected void onProgressUpdate(Void... values) {}

    @Override
    protected void onPostExecute(String result) {

        if (result != null && !result.equals("")) {
            try {
                JSONObject resObject = new JSONObject(result);

                } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

3）在你的onCreate方法中

     @Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView("your layout");



    if ("check here where network/internet is avaliable") {

        new HTTPdemo().execute("");
    }

   }

我提供的代码片段按以下方式工作，

1)Android设备发送URL+数据到服务器

2)Server [使用的 Azure 平台] 接收数据并给出确认

现在应该在客户端（Android）编写的代码已提供给您，在服务器接收数据的后续部分是

• 服务器需要接收数据
• 应该使用网络服务来做到这一点
• 在服务器端实现Web服务
• 每当 android 推送 URL+数据时都会调用 Web 服务
• 一旦获得数据，就可以根据需要对其进行操作
