从Android应用程序向Django视图发送POST请求

我正在尝试从android设备读取QRCode，并将提取的ID发送到使用Django构建的web服务器

我遵循教程，数据被正确地发送到教程服务器。 然后我将发送的数据自定义为一个整数（id），并将其发送到我的服务器链接，但view方法根本没有启动

我的代码：

Android代码：

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    if (requestCode == 0) {
        if (resultCode == RESULT_OK) {
            String data = intent.getStringExtra("SCAN_RESULT");
            new HttpAsyncTask().execute("https://bfish.neuro.mpg.de/baierlab/inventory/");

        }
    }
}

private class HttpAsyncTask extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... urls) {

        String test_data = "111";           

        return POST(urls[0],test_data);
    }
    // onPostExecute displays the results of the AsyncTask.
    @Override
    protected void onPostExecute(String result) {
        Toast.makeText(getBaseContext(), "Data Sent!",       Toast.LENGTH_LONG).show();
    }
}

public static String POST(String url, String data){
    InputStream inputStream = null;
    String result = "";
    try {

        HttpClient httpclient = new DefaultHttpClient();

        HttpPost httpPost = new HttpPost(url);

        String json = "";

        JSONObject jsonObject = new JSONObject();
        jsonObject.accumulate("cross_id", data);

        json = jsonObject.toString();

        StringEntity se = new StringEntity(json);

        httpPost.setEntity(se);

        httpPost.setHeader("Accept", "application/json");
        httpPost.setHeader("Content-type", "application/json");

        HttpResponse httpResponse = httpclient.execute(httpPost);

        inputStream = httpResponse.getEntity().getContent();

        if(inputStream != null)
            result = convertInputStreamToString(inputStream);
        else
            result = "Did not work!";

    } catch (Exception e) {
        Log.d("InputStream", e.getLocalizedMessage());
    }       
    return result;
}

我知道我必须从request.body读取数据，但该方法根本没有启动

非常感谢。

有什么错误？@arcegk问题是我的服务器没有收到帖子。我没有收到错误消息或任何其他信息。android应用程序告诉我数据正在发送，但服务器没有接收！

def inventory(request):

    # Just write something on a file to know the method is being fired or not 

    if request.method == 'POST':

        # Try to parse the cross_id from the POST

url(r'^inventory', views.inventory, name='inventory')
