ASHNET library enhancement (1.4.184): New function exposed to request a Google API access token based on a private key. This was added specifically to facilitate downloading a file from Google Cloud Storage when the private key is supplied by the owner, but is potentially useful in other contexts as well. The function can be called via DYNLIB as follows:
funcsig$ = "GetGoogleCloudAccessToken(Zziz)i"
xcall DYNLIB, dlctl, funcsig$, prvkey$, token$, sizeof(token$), url, rc
Parameters
prvkey$ (String) [in]
is a json string containing a private key, something like:
{
"type": "service_account",
"project_id": "chilkattest-1350",
"private_key_id": "fa2e36ee26986eab628b59868af8bec1d1c64c38",
"private_key": "-----BEGIN PRIVATE KEY-----\nMII....jSdy\n-----END PRIVATE KEY-----\n",
"client_email": "598922945xxxxxxxxxxxxa@developer.gserviceaccount.com",
"client_id": "5989229452xxxxxxxxxxxxxxxxa.apps.googleusercontent.com",
"auth_uri": "https:!accounts.google.com/o/oauth2/auth",
"token_uri": "https://accounts.google.com/o/oauth2/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/m...com"
}
token$ (String,2048) [out]
receives the access token
cb (Num) [in]
specifies the size of the token$ parameter
url (String) [in]
optional url; default: https://www.googleapis.com/auth/cloud-platform
