When using httpx.Client with proxies, authentication fails #779
Description
When doing something like this
proxy = {
'http' : 'http://user:pass@X.X.X.X:YY',
'https' : 'http://user:pass@X.X.X.X:YY'
}
def run_sync(url):
with httpx.Client(verify=False, proxies=proxy) as client:
response = client.get(url)
print(response)
>>> run_sync('http://www.google.com')
<Response [407 Proxy Authentication Required]>
For a private proxy that includes authentication, the request will fail with a "Proxy Authentication Required" error. I think httpx is doing something like this:
>>> from urllib3 import ProxyManager
>>> proxy = urllib3.ProxyManager('http://user:pass@x.x.x.x:yy')
>>> x = proxy.request('GET', 'http://google.com/')
>>> x.status
407
instead of this
>>> from urllib3 import ProxyManager, make_headers
>>> default_headers = make_headers(proxy_basic_auth='user:pass')
>>> proxy = urllib3.ProxyManager('http://x.x.x.x:yy', headers=default_headers)
>>> x = proxy.request('GET', 'http://google.com/')
>>> x.status
200
