urllib3.ProxyManager 给出身份验证错误 [英] urllib3.ProxyManager is giving authentication error

问题描述

我正在尝试使用 urllib3.ProxyManager 发送 https 请求.我的代码看起来像这样

I am trying send a https request using urllib3.ProxyManager. My code looks something like this

default_headers = urllib3.util.make_headers(proxy_basic_auth='user:passwd')
http = urllib3.ProxyManager(proxyUrl, headers=default_headers, ca_certs=certifi.where())
http.request('GET', url)

我收到以下错误 -

MaxRetryError(_pool, url, error or ResponseError(cause))
urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='clinicaltrials.gov', port=443): Max retries exceeded with url: /ct2/results?term=Lilly&displayxml=true&count=5000 (Caused by ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 407 Proxy Authentication Required')))

谢谢，亚特里克

推荐答案

我认为你需要在 ProxyManager 中设置 proxy_headers，而不是 headers:

I think you need to set proxy_headers, not headers in ProxyManager:

default_headers = urllib3.util.make_headers(proxy_basic_auth='user:passwd')
http = urllib3.ProxyManager(proxyUrl, proxy_headers=default_headers, ca_certs=certifi.where())
http.request('GET', url)

请参阅文档中的 urllib3.poolmanager.ProxyManager:https://urllib3.readthedocs.io/en/latest/reference/

See urllib3.poolmanager.ProxyManager in the docs: https://urllib3.readthedocs.io/en/latest/reference/
