简介在docker容器中使用requests库发送请求出现Python - requests.exceptions.SSLError - dh key too small的错误。

I'm scraping some internal pages using Python and requests. I've turned off SSL verifications and warnings.

requests.packages.urllib3.disable_warnings()
page = requests.get(url, verify=False)

On certain servers I receive an SSL error I can't get past.

Traceback (most recent call last):
  File "scraper.py", line 6, in <module>
    page = requests.get(url, verify=False)
  File "/cygdrive/c/Users/jfeocco/VirtualEnv/scraping/lib/python3.4/site-packages/requests/api.py", line 71, in get    return request('get', url, params=params, **kwargs)
  File "/cygdrive/c/Users/jfeocco/VirtualEnv/scraping/lib/python3.4/site-packages/requests/api.py", line 57, in request    return session.request(method=method, url=url, **kwargs)
  File "/cygdrive/c/Users/jfeocco/VirtualEnv/scraping/lib/python3.4/site-packages/requests/sessions.py", line 475, in request
    resp = self.send(prep, **send_kwargs)
  File "/cygdrive/c/Users/jfeocco/VirtualEnv/scraping/lib/python3.4/site-packages/requests/sessions.py", line 585, in send
    r = adapter.send(request, **kwargs)
  File "/cygdrive/c/Users/jfeocco/VirtualEnv/scraping/lib/python3.4/site-packages/requests/adapters.py", line 477, in send    raise SSLError(e, request=request)
requests.exceptions.SSLError: [SSL: SSL_NEGATIVE_LENGTH] dh key too small (_ssl.c:600)

处理方法：

import requests
import urllib3


requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS = 'ALL:@SECLEVEL=1'
