Solving the Mystery of Axios PATCH Requests Not Being Recognized as Ajax

In the world of web development, Axios has become a popular choice for making HTTP requests. However, a common issue that developers encounter is related to Axios PATCH requests not being recognized as Ajax. This can lead to unexpected behaviors, particularly when your server makes decisions based on whether a request is an Ajax call. Let's explore the problem and provide step-by-step guidance to effectively address it.

Understanding the Problem

When you send a PATCH request using Axios and the server doesn't acknowledge it as an Ajax request, you might see unexpected responses. For instance, you might execute your Axios request like this:

Despite working correctly, if the server checks for Ajax requests using the ajax() method and doesn’t recognize the request, it can cause issues. The server usually checks for the presence of specific headers to determine the type of request.

Why is Axios Not Recognized as Ajax?

The server-side check often relies on the HTTP_X_REQUESTED_WITH header, which is commonly added to Ajax requests. When using Axios, this header is not automatically included, which is why the server may respond that it's "not ajax."

Why is this Header Important?

Header Significance: Some server-side frameworks differentiate between standard HTTP requests and Ajax requests using this header.

Conditional Logic: Your server-side code might execute different logic based on the request type. If it defaults to non-Ajax behavior, you may not achieve the desired result.

Solution: Manually Add the Ajax Header

The good news is that you can easily solve this issue by manually adding the required header to your Axios requests. Here’s how to implement this solution step-by-step:

Step 1: Set the Header in your JavaScript File

By adding the following line at the top of your JavaScript file, you ensure that every Axios request includes this header:

Step 3: Confirm the Changes on the Server-Side

On the server-side, ensure your controller properly checks for Ajax requests. Here’s how this might look in your PHP controller:

Step 4: Test Your Implementation

Trigger your PATCH request through the button and check the server response.

Confirm if your server now recognizes the request as Ajax.

Conclusion

Axios is a powerful library that simplifies HTTP requests, and by properly configuring your requests, you can avoid hiccups in your application's functionality. Remember that sending the right headers can make all the difference in how your server interprets requests. By adding X-Requested-With to your headers, you can ensure that your PATCH requests are recognized as Ajax and processed correctly.

With this approach, you should be well-equipped to handle Axios PATCH requests without facing the Ajax recognition issue. Happy coding!
