python无法访问https出现URLError

Question

URLError: "urlopen error [Errno 8] ssl.c:503: EOF occurred in violation of protocol"
直接通过浏览器可以访问，昨天也是好使的，今天就不行了
代码：
url="https://ipaddress/xxx/xxx/xxx"
kw={'xxx':'xxx'}
data = urllib.urlencode(kw)
req = urllib2.Request(url,data)
base64string = base64.encodestring('%s:%s' % ('xxx', 'xxx'))[:-1] #这里最后会自动添加一个\n
authheader = "Basic %s" % base64string
req.add_header("Authorization", authheader)
return_data = urllib2.urlopen(req) #请求url
data = return_data.read() #读取内容
print data
错误：
