问题描述
python urlopen 怎么同时使用url，参数，头信息和context？原来的代码是这样的：
req = urllib2.Request(url, obj, headers)
opener = urllib2.urlopen(req)
现在出现[SSL: CERTIFICATE_VERIFY_FAILED]的报错
所以我需要使用下面的代码处理报错：
import ssl
import urllib2
context = ssl._create_unverified_context()
print urllib2.urlopen("https://aa.com/", context=context).read()
请问怎么把这个context加入进去？ 尝试过 print urllib2.urlopen(url=req, context=context).read() 报错： HTTP Error 503: Service Unavailable
我使用下面的代码，也是一样报错HTTP Error 503: Service Unavailable
import sslssl._create_default_https_context = ssl._create_unverified_context
