Python在解析数据之前请求登录页面

我想解析页面中的数据，但该数据仅显示注册用户。所以，我必须先登录，然后解析它。解析端并没有问题，但登录端有问题。这是我唯一的登录代码：

我已将私有域名更改为domain.com

如果登录成功，我需要查看

https://domain.com/mesaj/

页面，但由于登录失败，它会再次重定向登录页面

此外，以下是从Google Chrome捕获的登录页面的标题：

with requests.Session() as c:
    url = 'https://domain.com/giris?returnUrl=https://domain.com/'
    USERNAME = 'xxxxxxx@gmail.com'
    PASSWORD = '1111111'
    c.get(url)
    __RequestVerificationToken = c.cookies['__RequestVerificationToken']
    login_data = dict(__RequestVerificationToken=__RequestVerificationToken, UserName=USERNAME, Password=PASSWORD, ReturnUrl='https://domain.com/', RememberMe='false')
    c.post(url, data=login_data, headers={"Referer": "https://domain.com/giris?returnUrl=https%3A%2F%2Fdomain.com%2F"})
    page = c.get('https://domain.com/mesaj/')
    print page.content
