.Net Core WebApp API Endpoints don't work once deployed to Azure

Question

I'm having an issue with deploying a WebApp / API to Azure.

When I run it locally on localhost:44385//api/user/getuser/1, it returns the JSON for that user, once deployed to an App Service on Azure, it starts returning a 404.

Its running on the free version as its for a uni assignment. I've spent hours poking around and reading, and cant seem to find where i've gone wrong in the setup. Hoping someone might of had a similar issue.

Have you checked to make sure the server's routing rules are correct and that it's not looking in the directory structure?

Answer 2

Please verify below points:

1. That the Connection String of DB is correctly picked up by your Web API/it's correctly setup and configured.
2. If the DB and table/collection is present when you query and if not then you are creating it through your code.
3. If your data is present at the right place (User with ID = 1 in DB and collection/table you are querying) .
4. If your code is not throwing 404 incorrectly (even in positive scenarios).
