即时为我的应用程序执行登录注册，我必须将它们与microsoft azure集成在一起。但是，尽管遵循了microsoft azure给出的教程，我仍然无法将我的“字符串”插入其数据库中。代码中也没有错误，因此我不确定哪里出错了。以下是我的代码。

这是一段代码片段，希望它能为您提供帮助。
1）一个携带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("");
}
}
我提供的代码段以下列方式工作，
1） Android设备将URL +数据发送到服务器
2）服务器[使用的Azure平台]接收数据并发出确认
现在提供应该在客户端（Android）编写的代码，在服务器上接收该数据的后半部分
