What happens when a 404 error occurs?
A 404 error is often returned when pages have been moved or deleted. 404 errors should not be confused with DNS errors, which appear when the given URL refers to a server name that does not exist. A 404 error indicates that the server itself was found, but that the server was not able to retrieve the requested page.
Should delete throw 404?
If the resource is deleted you can’t DELETE it again (as it doesn’t exist). So a 404 Not Found is appropriate. The DELETE method is idempotent, so the effects should always be the same.
Should you put a 404 return?
In the second case an error should be returned, but not a 404 — possibly a 412 Precondition Failed or maybe just a 400 Bad Request. Thoughts? IMHO from the client perspective you are starting at the root ( / ) and walking down the path. If at any point some path part is not found, you should throw 404 eagerly.
Is it correct to return 404 when a rest resource is not found?
Yes, it is pretty common to return 404 for a resource not being found. Just like a web page, when it’s not found, you get a 404. It’s not just REST, but an HTTP standard.
When do I get a 404 request from the REST API?
the real HTTP 404 when the rest API is not available in the given url, it is thrown by the application server or web-server where the rest API application runs. client get back HTTP 404 as well when there is no data in database based on the where condition of the query.
What does 404 not found mean on MyWebsite?
11. 404 Not Found technically means that uri does not currently map to a resource. In your example, I interpret a request to http://mywebsite/api/user/13 that returns a 404 to imply that this url was never mapped to a resource. To the client, that should be the end of conversation.
Why do I get a 404 error when I type in Fiddler?
You need to use something like Fiddler. free to use, and look at the raw URL at the time of the 404 error. If the URL and the parms on the URL to not match the method to be accessed then it is 404 ‘Not found’. There is something wrong with the URL as to why the method cannot be found, like bad parm.
