Generating the request to list the vpc details with IAM token which is kept in authorization header - The request has been generated from React App - 

https://urls.cloud.ibm.com/v1/vpcs?version=2019-08-06&generation=1

Configuration 

config = {
        headers: {
        "Authorization": "Bearer lmtmlmlm",
        "Access-Control-Allow-Origin": "*"
      }
    }

The request was failed during the pre-flight request, it seems that the browser request headers are asking the server for permissions to make the actual request.

Can you suggest to overcome the problem.

The instructions here worked well for me: https://cloud.ibm.com/docs/vpc-on-classic?topic=vpc-on-classic-creating-a-vpc-using-the-rest-apis

I noticed you used the url: https://urls.cloud.ibm.com while these docs suggested https://us-south.iaas.cloud.ibm.com

rias_endpoint="https://us-south.iaas.cloud.ibm.com"
iam_token='Bearer zzzrandomstuff...eyJraWQiOiIyMDE5MDUxMyIsImFsZyI6IlJTMjU2In'
version="2019-05-31"
curl -X GET "$rias_endpoint/v1/vpcs?version=$version&generation=1" -H "Authorization: $iam_token"

  • Yes, i have used the correct URL which is mentioned in the documentation as "https://us-south.iaas.cloud.ibm.com". However, i was requesting it through browser with my own react application, browser itself sends pre-flight request to server to ensure CORS. Hence, the next subsequent request was failing from browser. I was able to execute it well with curl. The problem is generated when it is implemented through UI app like react etc from browser. hope it clarifies. thanks – DEngineer Aug 07 '19 at 05:24
