POST Requests Being Converted to GET Requests in Tizen Web Application

Original Created Sep 10, 2018 | Regeneration Apr 22, 2026

Question

I am developing a Tizen Web application that needs to interface with a device requiring POST requests with empty bodies. The following code works fine in a web browser:

this.xhttp = new XMLHttpRequest();
this.xhttp.open("POST", url);
this.xhttp.send('');

However, when I use the same code in a Tizen Web application, it fails. The debug console shows that an HTTP GET request is being sent instead of POST. I also tried using jQuery's AJAX method with the same result:

$.ajax({
  type: "POST",
  url: url,
  data: null
});

Why are these requests being logged as failed GET requests in Tizen?

Answer

Problem Understanding

The issue occurs when making POST requests in a Tizen Web application, where the requests are being converted to GET requests unexpectedly. This behavior differs from standard web browsers where the same code works correctly.

Solution Methods

Check Network Policy Configuration:
- Ensure you have added the necessary network privileges in your config.xml file:
```
<tizen:privilege name="http://tizen.org/privilege/internet"/>
<tizen:access origin="*" subdomains="true"/>
```
Verify Request Headers:
- Explicitly set the Content-Type header in your request:
```
this.xhttp.setRequestHeader("Content-Type", "text/plain");
```
Use Fetch API as Alternative:
- Consider using the modern Fetch API, which might handle requests more reliably:
```
fetch(url, {
  method: 'POST',
  headers: {
    'Content-Type': 'text/plain'
  },
  body: ''
});
```

Code Examples

Here is a complete example with proper configuration:

var xhr = new XMLHttpRequest();
xhr.open("POST", "https://your-api-endpoint.com");
xhr.setRequestHeader("Content-Type", "text/plain");
xhr.send('');

Additional Tips

Ensure your Tizen application has the correct privileges and access policies.
Test your application in the Tizen emulator or on a physical device to verify network behavior.
Check the Tizen documentation for any updates or changes in the XMLHttpRequest implementation.
