我们有两个应用程序都在Google App Engine上运行.App1向app2发出请求,作为经过身份验证的用户.通过从Google ClientLogin请求与cookie交换的身份验证令牌来进行身份验证.然后将cookie用于后续请求(如所描述的在这里).App1运行以下代码:

class AuthConnection:

    def __init__(self):            
        self.cookie_jar = cookielib.CookieJar()    
        self.opener = urllib2.OpenerDirector()
        self.opener.add_handler(urllib2.ProxyHandler())
        self.opener.add_handler(urllib2.UnknownHandler())
        self.opener.add_handler(urllib2.HTTPHandler())
        self.opener.add_handler(urllib2.HTTPRedirectHandler())
        self.opener.add_handler(urllib2.HTTPDefaultErrorHandler())
        self.opener.add_handler(urllib2.HTTPSHandler())
        self.opener.add_handler(urllib2.HTTPErrorProcessor())
        self.opener.add_handler(urllib2.HTTPCookieProcessor(self.cookie_jar))
        self.headers = {'User-Agent': 'Mozilla/5.0 (Windows; U; ' +\
                                       'Windows NT 6.1; en-US; rv:1.9.1.2) ' +\
                                       'Gecko/20090729 Firefox/3.5.2 ' +\
                                       '(.NET CLR 3.5.30729)'
                        }

    def fetch(self, url, method, payload=None):
        self.__updateJar(url)
        request = urllib2.Request(url)
        request.get_method = lambda: method
        for key, value in self.headers.iteritems():
            request.add_header(key, value)
        response = self.opener.open(request)
        return response.read()

    def __updateJar(self, url):

        cache = memcache.Client()
        cookie = …
