无法使用Selenium & Splinter添加cookie

Question

根据下面的内容，我不知道如何解决这个非常简单的使用场景。

我有一个脚本(我每个月运行一次)，它在功能上做同样的事情，并且在一个月前就开始工作了。

我希望你能给我一些建议，让我开始研究为什么这个方法不起作用。

$ python3
Python 3.6.1 (default, Mar 23 2017, 16:49:06)

>>> from selenium import webdriver
>>> from splinter import Browser
>>> chrome_options = webdriver.ChromeOptions()
>>> browser = Browser('chrome')
>>> browser.cookies.add({'aaa':'bbb'})

Answer 1

您应该先打开url，然后加载cookie，然后可以用cookies.you打开下一个url，如果您想打开相同的url，也可以这样打开：

driver = webdriver.Chrome(executable_path=r'X:\home\xxx\chromedriver.exe')

cookies = pickle.load(open("cookies.pkl", "rb"))
driver.get("https://www.douban.com/")
for cookie in cookies:
    driver.add_cookie(cookie)
driver.get("https://www.douban.com/")

希望这能帮上忙

Answer 2

弗洛伦特B的回答也对我有用，只是想把它放在正确的地方。

需要在某些browser.cookies.add之后调用browser.visit(...)

见Florent的评论：

方法browser.cookies.add绑定到当前域，该域在示例中未定义。您需要首先使用driver.get('http://...')设置域
