javascript - vue+iview upload fails to pass parameters. The cross-domain problem has been solved in the background. It still reports 403. What's going on?

Question

Answer 1

Cross-domain means you can’t get the return value. 403 means you do not have permission to access the interface. Don’t get confused

403 error, indicating that the resource is unavailable. The server understands the client's request but refuses to process it, usually due to a WEB access error caused by the permission settings of the file or directory on the server.
