405 errors may occur in the following situations in web development

1. The request mode at the front end does not match that at the background:

For example, if you use post in the background and get in the front end, a 405 error will appear. So just let them

If you keep consistent, you won’t report an error

2. The request parameters submitted at the front end are inconsistent with those at the back end:

In many cases, we will splice several parameters behind the request path. Once the spliced parameters are consistent with the parameters to be accepted in the front-end controller

Inconsistent parameters (inconsistent names or inconsistent numbers) will also report an error of 405

3. The request path is not written correctly, and sometimes 405 errors may occur
