Upload image to imgur failed because of cors

Question

I'm trying to upload an image to imgur with js (browser) and get a CORS error:

Access to XMLHttpRequest at 'https://api.imgur.com/3/upload' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

But preflight request contains Access-Control-Allow-Origin header:

The request itself:

What I'm missing? this is because access-control-allow-credentials set to true ?

Answer 1

问题是与他们的API文档：\\的网址是： https://api.imgur.com/3/image而不是https://api.imgur.com/3/upload为这里说： https：//开头apidocs .imgur.com /＃c85c9dfc-7487-4de2-9ecd-66f727cf3139

Answer 2

according todoc https://api.imgur.com/3/upload doesnt have necessary header ,

but on the right side ,the curl example use https://api.imgur.com/3/image has Access-Control-Allow-Origin header

and somehow they will check your referer, which means if you are in develop mode like webpack dev mode use localhost:8000 it will always return 429 too many request exception
