请求 Microsoft 图形 API 时出现 SSL 错误

Question

I trying to get integrate Microsoft Graph API into the airflow application docker-compose. And I have a self-signed SSL certificate for my domain.

following is the sample of DAG (pythonOperator): [I'm using the msal pypi package]

app_meta = MicrosoftGraphAPI.get()
app = msal.ConfidentialClientApplication(
   app_meta['client_id'],
   authority=app_meta['authority'],
   client_credential=app_meta['client_credential'],
   token_cache=None,
)

Error:

    WARNING - Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])"))': /d8c857c0-b2da-48fd-9b28-db5792c0d481/v2.0/.well-known/openid-configuration

UPDATE: I don't want to ignore certificate validation. How to fix it

Answer 1

Earlier intermediate CA certificates were optional, but now it is mandatory that you must have all the root and intermediate certificates available in certificate chain. I also faced this issue while connecting to nuget site for downloading packages, so i installed "BaltimoreCyberTrustRoot" , "Microsoft Azure TLS Issuing CA 01" and "DigiCertGlobalRootG2". It worked for me.
