Why can't I establish a connection to the Uber API?
我按照文档运行代码
1 2 3 4 5 6 | 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) |
不过，我在代理服务器后面。引发了以下连接错误。

这可能有助于向uber python sdk添加对代理的支持：如何通过python中的代理打开带有urllib的网站？
