Answer 1

We could use the accesstoken to access the you azure function api directly, if your azure function authentication level is anonymous or function key is also required.

I get the access token with your mentioned way. According to the Azure Resources portal(https://resources.azure.com/), the default allowedAudiences is

  "https://{functionAppName}.azurewebsites.net/.auth/login/aad/callback"

So I add the https://{functionAppName}.azurewebsites.net/ as allowed aduiences

Then I can use the access token directly. I test it with postman.

We also could use the following way to get easy auth token. The access token is the token that you got.

Post https://xxx.azurewebsites.net/.auth/login/aad
Content-Type:application/json
{
    "access_token":"eyJ0eXAiOix...rtf2H7lyUL-g34HVw"
}

After that we could use the get token to access the azure function api
