Azure AD OAuth token refresh gives error AADSTS50000

问题

After successfully authenticating, I want to refresh my authorization token, so I issue the following request

curl -X POST \
  https://login.microsoftonline.com/<my-tenant>/oauth2/v2.0/token \
  -H 'Cache-Control: no-cache' \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -F grant_type=refresh_token \
  -F refresh_token=<my-refresh-token> \
  -F client_id=<my-client-id> \
  -F client_secret=<my-client-secret>

However, instead of returning with a new token, I get the following response:

{
    "error": "server_error",
    "error_description": "AADSTS50000: There was an error issuing a token.\r\nTrace ID: bb72ee21-7df2-4949-8375-e6d97b621300\r\nCorrelation ID: 719ea759-622b-4d63-be17-56fd6c255195\r\nTimestamp: 2018-06-15 09:07:13Z",
    "error_codes": [
        50000
    ],
    "timestamp": "2018-06-15 09:07:13Z",
    "trace_id": "bb72ee21-7df2-4949-8375-e6d97b621300",
    "correlation_id": "719ea759-622b-4d63-be17-56fd6c255195"
}

The tenant, client id and client secret are all the same as those used when obtaining the refresh token. Yet, something is apparently missing or incorrect - but what?

回答1:

You are missing the mandatory scope parameter as described here.

You also need to provide a redirect_uri, although you just make a POST request.

And the redirect_uri must match the redirect_uri used in the original authorization call.

When refreshing an access token you have to provide a scope for which you would like to get the token. Also make sure that you understand you can only refresh the access_token, not the id_token. And access_token always has a purpose (scope).

Everything described in the documentation.
