Python通过证书调用基于SSL的Webservice
首先，普及一下各种类型的证书知识，以及格式之间的转换方法：http://liuleijsjx.iteye.com/blog/433853
然后就是调用代码了：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
__author__ = 'tan9le'
import urllib2 as u2
from suds.client import Client
from suds.transport.http import HttpTransport, Reply, TransportError
import httplib
class HTTPSClientAuthHandler(u2.HTTPSHandler):
def __init__(self, key, cert):
u2.HTTPSHandler.__init__(self)
self.key = key
self.cert = cert
def https_open(self, req):
#Rather than pass in a reference to a connection class, we pass in
# a reference to a function which, for all intents and purposes,
# will behave as a constructor
return self.do_open(self.getConnection, req)
def getConnection(self, host, timeout=300):
return httplib.HTTPSConnection(host, key_file=self.key, cert_file=self.cert)
class HTTPSClientCertTransport(HttpTransport):
def __init__(self, key, cert, *args, **kwargs):
HttpTransport.__init__(self, *args, **kwargs)
self.key = key
self.cert = cert
def u2open(self, u2request):
tm = self.options.timeout
url = u2.build_opener(HTTPSClientAuthHandler(self.key, self.cert))
if self.u2ver() < 2.6:
socket.setdefaulttimeout(tm)
return url.open(u2request)
else:
return url.open(u2request, timeout=tm)
# These lines enable debug logging; remove them once everything works.
def getClient(url, key, cert):
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.DEBUG)
c = Client(url,transport = HTTPSClientCertTransport(key, cert))
return c
def websevicewithcer(url):
#key文件是从pfx导出的，命令是：openssl pkcs12 -in xxx.pfx -nocerts -nodes -out private.key
key = 'D:/Work/cer/private.key' #这里换成你调用端的私钥文件
#cer是IE导出的，记得要用Base64编码格式的
cert = 'D:/Work/cer/public.cer' #这里换成你要调用的网址的客户端证书文件
client = getClient(url, key, cert)
result = client.service
return result
def 自定义方法(param):
wsdl_url = 'https://ip:port/xxx/services/portname?wsdl'
websev = websevicewithcer(wsdl_url)
#调用方式websev.方法名（参数）
ws = websev.方法名(param)
return ws
if __name__ == '__main__':
result = 自定义方法('参数')
print result
