JSON is the expected content type of modern APIs, and exceptions should be no different. Learn how to build a middleware component that will serialize unhandled exceptions in a friendly way.
- [Instructor] ASP.NET core returns http 500…if an unhandled exception occurs in your API.…This is the right status code to return…but it also returns this html document…which feels a little weird for a JSON on API.…We can improve this behavior by creating an…exception filter that will catch any unhandled exception…and send the error message back to the client…as a nicely formatted JSON response.…To do this, let's make a class that represents…the error message body.…I'll create a folder here called Models.…
And then I'll create a model called ApiError.…We just need a few properties here.…We'll say we have a string property called Message…and another string called Detail.…Now we'll make a folder called Filters.…And create a filter called JsonExceptionFilter.…A filter is a chunk of code that runs before or after…ASP.Net core processes a request.…
Filters that handle errors and exceptions…are called exception filters.…And there's a special interface we can implement here…called IExceptionFitler.…Need to import this name space.…
