我正在处理 Anthony Briggs. 给出的示例代码,但是它似乎没有将 cookie 保存回定义的 cookie 文件中。
我修改的代码。我改用 LWPCookieJar 是因为它应该是 fully compatible 并且还将登录代码删除到一个单独的函数中,以便我可以首先测试我是否登录,然后如果不是,则调用登录功能。
如果我使用一个对象登录,获取新的 cookie,保存它们,然后创建一个加载相同文件的新对象,它会恢复为登录前存储的 cookie。
测试代码:
facebookObject = FacebookBrowser(cookie_filename)
#check if authenticated
success=myAuthenticationTest(facebookObject)
if not success:
facebookObject.setupUser(facebookObject.login, facebookObject.password, cookie_filename)
resp = facebookObject.opener.open(testurl) #new cookies should be set
facebookObject.cj.save(cookie_filename)
saved_cookies = facebookObject.cj
facebookObject2 = FacebookBrowser(cookie_filename)
newly_loaded_cookies = facebookObject2.cj
#saved_cookies != newly_loaded_cookies
类(class)代码:
class FacebookBrowser(object):
def __init__(self,cookie_filename):
""" Start up... """
self.login = xxxxx
self.password = yyyyyy
self.cookie_filename = cookie_filename
self.cj = cookielib.LWPCookieJar(cookie_filename)
if os.access(cookie_filename, os.F_OK):
self.cj.load()
self.opener = urllib2.build_opener(
urllib2.HTTPRedirectHandler(),
urllib2.HTTPHandler(debuglevel=0),
urllib2.HTTPSHandler(debuglevel=0),
urllib2.HTTPCookieProcessor(self.cj)
)
self.opener.addheaders = [
('User-agent', ('Mozilla/5.0 (Windows; U; Windows NT 6.1; he; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3'))
]
def setupUser(self, login, password,cookie_filename):
# need this twice - once to set cookies, once to log in...
self.loginToFacebook()
self.loginToFacebook()
self.cj.save()
self.opener = urllib2.build_opener(
urllib2.HTTPRedirectHandler(),
urllib2.HTTPHandler(debuglevel=0),
urllib2.HTTPSHandler(debuglevel=0),
urllib2.HTTPCookieProcessor(self.cj)
)
self.cj.save()
def loginToFacebook(self):
"""
Handle login. This should populate our cookie jar.
"""
login_data = urllib.urlencode({
'email' : self.login,
'pass' : self.password,
})
response = self.opener.open("https://login.facebook.com/login.php", login_data)
return ''.join(response.readlines())
最佳答案
我刚刚在 another forum 上读到我需要在所有 .save() 和 .load() 方法中设置 ignore_discard=True
。
关于python - Cookie Jar Lib 不会将 cookie 保存回文件?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/3630307/
