If that, you can directly call you backend's API. But, what I can see is that you tried to call "https://gateway.../v3/oauth/token" from your frontend, right? It would cause cross-domain error because it violates the policy; browser would not...

@Wayne Theron Since your API is redirecting directly to Blob Storage, CORS has to be setup there as well since the browser makes the call directly. Check the official doc for setting up CORS for Azure Storage for more details. The same can be set from the portal as well like be...

如果服务器否定了"预检"请求,会返回一个正常的HTTP回应,但是没有任何CORS相关的头信息字段。这时,浏览器就会认定,服务器不同意预检请求,因此触发一个错误,被XMLHttpRequest对象的onerror回调函数捕获。控制台会打印出如下的报错信息。 XMLHttpRequest cannot load http://api.alice.com. ...
For example, if your API is hosted on https://{api_id}.execute-api.{region}.amazonaws.com/ and you want to call your API from a web application hosted on example.com, your API must support CORS. If you configure CORS for an API, API Gateway automatically sends a response to pre...
