How can I establish a connection between my Android app and a PHP server using HTTPUrlConnection to send data in the output stream and ensure that the server receives it in the $_

When using HttpURLConnection to send a JSON query to a PHP server, I encountered issues with the communication not working as expected.

Despite having a successful connection and receiving proper error responses from the server side, it seems that the PHP server is unable to retrieve the JSON string in the variable $_POST. The JSON data sent looks like this:

{"id":55,"date":"2011111","text":"","latitude":13.0,"longitude":123.0,"share":0,"image":"Image","sound":"sound"}

On the Android side, the code snippet used is quite straightforward:

    // Code snippet

The PHP server-side code appears as follows:

// Server code

Upon conducting some research, I discovered a workaround that involves modifying the server-side code. By making adjustments such as extracting the JSON data from 'php://input', the PHP server can now effectively handle the JSON information received from the Android application.

Unfortunately, the challenge lies in the inability to modify the code on the actual server. This limitation raises questions about why the $_POST variable is not being populated appropriately.

Answer №1

Your data is being transmitted in JSON format, but not within the $_POST array, which is why $_POST appears empty. If you are unable to modify the server-side code, consider using my HttpConnection class as an alternative solution. This should help resolve the issue.

import org.json.JSONException;
import org.json.JSONObject;

// Code for HttpConnection class goes here

To make a POST request, simply utilize the sendRequest method by providing the link and the data to be sent using a HashMap.
