Why requests raise this exception “check_hos…

p={
    'http':'http://my correct proxy here',
    'https':'https://my correct proxy here'
    }
self.response=requests.get(url=url,headers=self.headers,timeout=(6,15),proxies=p)

And then it raise the exception:

ValueError: check_hostname requires server_hostname

Please help me solve the problem and the best way is to show me the right code. I am very confused and frustrated for the problem!!

Answer

As I understand, in new urllib3 the main schema of proxy was changed… can read here. This settings help for me (for urllib3=1.26.4).

An old

proxy={
    'http':'8.88.888.8:8888',
    'https':'8.88.888.8:8888'
    }

The new

proxy={
    'https': 'https://8.88.888.8:8888',
    'http': 'http://8.88.888.8:8888',
    }

UPDATED

I have met this issue again for requests 2.26.0, but in this time it works with an old schema…

proxy={
    'http':'8.88.888.8:8888',
    'https':'8.88.888.8:8888'
    }

Why requests raise this exception “check_hostname requires server_hostname”?
