Question

如下所示，我不确定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）在功能上做同样的事情，并且使用在一个月前工作。

我很感激有关地方的任何指示，以开始研究为什么这不起作用。

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

Answer 1

您应该先打开url并加载cookie，然后才能打开带有cookie的下一个URL。如果要打开相同的URL，也可以像这样打开：

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/")

希望这会有所帮助

Answer 2

Florent B.的答案也适用于我，只是想把它放到正确的位置。

某些browser.cookies.add

之后需要调用

browser.visit(...)

见Florent的评论：

方法browser.cookies.add绑定到当前域，在您的示例中未定义。您需要先使用driver.get设置域名（＆＃39; http：//...'）

无法使用Selenium＆amp;添加cookie碎片
