python requests cookies的处理

兼容性

try:
    import cookielib  # 兼容Python2
except:
    import http.cookiejar as cookielib  # python 3 need import http.cookiejar

创建 session

session = requests.session()  

初始化创建cookies 对象

session.cookies = cookielib.LWPCookieJar(filename="cookies.txt")  # LWP实例化的cookie可直接调用save方法

请求之前,装载cookies

session.cookies.load(ignore_discard=True)

session访问网址

response = session.get("https://www.imooc.com", headers=header)  # more effective

登录成功后,将cookies 写入到指定文件中

session.cookies.save()

对cookie载入成功的判断

try:
    session.cookies.load(ignore_discard=True)
    print("Cookie正常加载")
except:
    print("Cookie未能加载")
