The art of debugging CURL requests in Magento 2

Magento 2 is a powerful e-commerce platform that allows developers to create custom solutions for their online stores. One important aspect of any e-commerce solution is the ability to interact with external APIs and services, and CURL is a common tool used for this purpose. In this post, we’ll explore various ways to check the CURL data that is passed in Magento 2 for debugging purposes, without modifying the env.php file.

It is possible to check the CURL data that is being passed in Magento 2 by using the $this->curl object. The $this->curl object is an instance of the \Magento\Framework\HTTP\Client\Curl class, which is used to make CURL requests in Magento.

You can use the following methods of this class to inspect the CURL data:

• getInfo() method: This method returns an associative array of information about the last transfer, such as the request headers, response headers, and response code.
• getHeaders() method: This method returns the headers of the last transfer as an array.
• getBody() method: This method returns the response body of the last transfer.

You can also call the getOptions() method to get all set options of the current curl instance.

For example:

$curl = $this->curl;
$curl->get('http://example.com');
$response = $curl->getBody();
$headers = $curl->getHeaders();
$info = $curl->getInfo();

You can then use the data returned by these methods to log or inspect the CURL data that is being passed. Keep in mind that you will need to do this inside of a class that extends the class that makes the CURL call.

I hope this tutorial was helpful to you in understanding how to debug CURL request in development world.
