Symfony RESTful API: Errors (Course 2)

In course 1, we added our basic endpoints with some nice tests (yes!).

Now, we turn to a huge part of APIs: handling and returning consistent errors. Seriously, this is more important than you might think - which is why we're covering this in episode 2.

So, let's handle errors, and let's do it gracefully:

• Handling Form Validation errors and response
• Disabling csrf_protection
• Introducing the api-problem JSON format
• Exception Listener!
• Consistent errors everywhere: 404's, 500's, oh my!
• Handling "extra fields" in your form

• Validation Errors Test
• Sending back Validation Errors
• PUT Validation and CSRF Tokens
• 99 api/problem+json(s)
• Modeling the Error: ApiProblem Class
• Keeping Problem types Consistent
• The All-Important HttpExceptionInterface
• Creating the Invalid JSON ApiProblem, and then...
• ApiProblemException
• Request Format: Why Exceptions Return HTML
• Global RESTful Exception Handling
• Handling 404's + other Errors
• The Helpful Detail Key
• Debugging and Cleanup
