我在这里遇到网站授权问题。我在Selenium上使用无头浏览器PhantomJS。 我做了什么：
driver.get('https://foo.com')
# some instructions to log in
# foo.com makes some requests to https://bar.foo.com and sets cookies for https://bar.foo.com domain
driver.get_cookies()
# no cookies for https://bar.foo.com
# any requests to https://foo.com are not autorized because the cookies from https://bar.foo.com are the ones that are needed, but not provided
有什么解决方法吗？一直在寻找解决问题很长时间没有成功。
还有一点需要注意：例如，chromedriver会将从AJAX请求收到的所有cookie收集到子域，而phantomjs则不会这样做。
