如何使用python在selenium webdriver中将cookie设置为特定的域？

Question

各位StackOverflow用户好。我试图实现的是防止当我的测试打开主页时出现烦人的帮助程序框。到目前为止，这是我用来打开主页的方法：

def open_url(self, url):
    """Open a URL using the driver's base URL"""
    self.webdriver.add_cookie({'name' : 'tour.index', 'value' : 'complete', 'domain' : self.store['base'] + url})
    self.webdriver.add_cookie({'name' : 'tour.map', 'value' : 'complete', 'domain' : self.store['base'] + url})
    self.webdriver.get(self.store['base'] + url)

但是，运行测试后返回的结果是：

2014-07-23 15:38:19.453057: X Message: u'You may only set cookies for the current domain' ;

如何在实际加载基本测试域之前设置cookie？

Answer 1

文档建议在设置cookies之前导航到一个虚拟url（例如404页面或图像路径）。然后，设置cookies，然后导航到主页面。

Selenium Documentation - Cookies

... you need to be on the domain that the cookie will be valid for. If you are trying to preset cookies before you start interacting with a site ... an alternative is to find a smaller page on the site ... (http://example.com/some404page)

所以，您的代码可能如下所示：

def open_url(self, url):
    """Open a URL using the driver's base URL"""

    dummy_url = '/404error'
    # Or this
    #dummy_url = '/path/to/an/image.jpg'

    # Navigate to a dummy url on the same domain.
    self.webdriver.get(self.store['base'] + dummy_url)

    # Proceed as before
    self.webdriver.add_cookie({'name' : 'tour.index', 'value' : 'complete', 'domain' : self.store['base'] + url})
    self.webdriver.add_cookie({'name' : 'tour.map', 'value' : 'complete', 'domain' : self.store['base'] + url})
    self.webdriver.get(self.store['base'] + url)
