httpresponse

I thought having the request header 'Accept': 'application/json' was what it was talking

问题 I have this code where the client uploads a file to the server through an AJAX POST request and then the server uploads that file to a cloud (cloudinary), and responds to the AJAX request after the upload is completed.

问题 I'm looking for some guidance for the correct response code & message when requesting for a resource that forms part of another resource. For example, a GET request on: users/{id} where the user does not exist would return a 404, with a message of user resource not found.
