Warum kann ich keine Verbindung zur Uber-API herstellen?

Question

lief ich den Code gemäß der Dokumentation

from uber_rides.session import Session 
from uber_rides.client import UberRidesClient 

session = Session(server_token=<TOKEN>) 
client = UberRidesClient(session) 
response = client.get_products(37.77, -122.41) 

ich aber hinter einem Proxy-Server bin. Und dieser folgende Verbindungsfehler wurde ausgelöst.

Answer 1

Dies wird wahrscheinlich die Unterstützung für einen Proxy auf den Uber Python sdk hinzufügen helfen: How can I open a website with urllib via proxy in Python?
