Preflight not working on put request?

Question

JavaScript

I send a put request using axios, but it says options to me, even though I set "preflight".

this.url.defaults.transformRequest = [(data) =>  JSON.stringify(data)]
 
        return this.url.put('/index.php/rest/' + type + '/signin',{
            number
        })

I did the same thing with post, but "preflight" worked for post

return this.url.post('/index.php/rest/' + post.type + '/signup',{
                "number" : post.number,
                "name" : post.name,
                "city_id" : post.city_id,
            })

Answer 1

If this is a cross-domain request, then you must first process OPTIONS, and then accept POST
Here it is described in detail

Answer 2

OOO, I found what the problem is, it turns out that the server side forbade the put request
