Why 2 classes Magento\Framework\HTTP\Client\Curl and Magento\Framework\HTTP\Adapter\Curl for same purpose?

Question

Magento Framework has 2 classes for Curl operations:

\Magento\Framework\HTTP\Adapter\Curl and

\Magento\Framework\HTTP\Client\Curl

What is specific use-case for each as both are capable of doing same job ?

Answer 1

NOT THE ACTUAL ANSWER

• Both classes are curl based wrapper classes.
• Tasks of the both classes remains the same such as connecting, writing, reading and closing connection to the server but in different way.

Adapter CURL

• Used as connector for Zend_Http_Client which has a internal framework - dependency on request type and response.
• Common method for GET/POST/DELETE/PUT
• First writes the request to the remote server using write() method and read the response using read() method.

Client CURL

• Class to work with HTTP protocol which directly calls curl lib, no dependency on Framework Zend or Laminas.
• Different method for GET/POST, separate methods available get() and post()
• For other methods(PUT/DELETE) one has to trigger - method makeRequest()

I would say to implement the code using Client CURL class only.
