我必须从Android应用程序发送一个Json对象到Azure Rest API，查看我的代码帮助我，使用其他API

Question

我想将json对象{“PersonID”：“124”，“DeviceID”：“123”，“ExpID”：“1234”，“ID”：“4566”}发送到特定的Azure Rest API URL

Ive尝试使用下面的代码它适用于URL-http://hmkcode.appspot.com/jsonservlet，但不适用于我的AZURE REST API的URL

main activity.Java

private String httpPost(String myUrl) throws IOException, JSONException 
   {
    String result = "";

    URL url = new URL(myUrl);

    // 1. create HttpURLConnection
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestMethod("POST");
    conn.setRequestProperty("Content-Type", "application/json; charset=utf-8");

    // 2. build JSON object
    JSONObject jsonObject = buidJsonObject();

    // 3. add JSON content to POST request body
    setPostRequestContent(conn, jsonObject);

    // 4. make POST request to the given URL
    conn.connect();

    // 5. return response message
    return conn.getResponseMessage()+"";
}

private class HTTPAsyncTask extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... urls) {
        // params comes from the execute() call: params[0] is the url.
        try {
            try {
                return httpPost(urls[0]);
            } catch (JSONException e) {
                e.printStackTrace();
                return "Error!";
            }
        } catch (IOException e) {
            return "Unable to retrieve web page. URL may be invalid.";
        }
    }
    // onPostExecute displays the results of the AsyncTask.
    @Override
    protected void onPostExecute(String result) {
        //tvResult.setText(result);
    }
}

public void send(View view) {
    Toast.makeText(this, "Clicked", Toast.LENGTH_SHORT).show();
    // perform HTTP POST request

        new HTTPAsyncTask().execute("URL");
}

private JSONObject buidJsonObject() throws JSONException {

    String w= "test";
    String a=  "ABCD";
    JSONObject jsonObject = new JSONObject();
    jsonObject.put("PersonID",token);
    jsonObject.put("DeviceID", Settings.Secure.ANDROID_ID);
    jsonObject.put("ExpID", w);

    jsonObject.put("ID", a);



    return jsonObject;
}

private void setPostRequestContent(HttpURLConnection conn, JSONObject jsonObject) throws IOException {

    OutputStream os = conn.getOutputStream();
    BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, "UTF-8"));
    writer.write(jsonObject.toString());
    Log.i(MainActivity.class.toString(), jsonObject.toString());
    writer.flush();
    writer.close();
    os.close();
}

activity_main.xml中

<Button
    android:id="@+id/btnSend"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:onClick="send"
    android:text="Send"
    tools:layout_editor_absoluteX="148dp"
    tools:layout_editor_absoluteY="266dp" />

我想将Token id，android id发送到Azure REST API。

我想帮助您，但我需要您提供更多信息。例如，您的代码段是否会抛出任何错误？ conn.getRepsonseMessage()回归了什么？此外，您表示您正在对该网址发帖。点击链接我确实得到了JSON，但当我尝试进行POST时出现500错误，这让我相信端点只接受GET。

我将遵循的步骤是使用像fiddler这样的工具对您的Azure API端点进行POST，并确保在您获得200秒后，该方面没有错误。
