我正在尝试启动一个曾经加载的网址会提示输入用户名和密码。
问题是，当我通过selenium IDE录制和运行测试用例时，它可以工作。 但是，当我尝试通过代码启动URL时，它变为灰色，并且不显示任何用户名和密码的提示
观察：
当我手动打开网址时
url =http://10.131.14.245:30016/index.html
它会在几秒钟后自动重定向到
http://10.131.14.245:30016/index.html#/Login
，用户名和密码的提示看起来可见。
但是在脚本执行期间，URL不会重定向自身，而且仍然是
url =http://10.131.14.245:30016/index.html
即使我们通过代码添加值'#Login'，它也不起作用
我正在使用 Python 2.7 硒3.6 Firefox 52.4 geckodriver v.018

由于Selenium，geckodriver和Firefox版本之间的不匹配，我发现您所观察到的错误类型。
根据发行说明 Selenium v3.6.0 应与 geckodriver v.0.18.0 （其中 geckodriver v.0.19.0 推荐）。
但是geckodriver v.0.18.0发行说明清楚地提到了以下内容：
geckodriver now recommends Firefox 53 and greater geckodriver compatible with Firefox 56 and greater
将 Firefox 升级到 v53+ 级别肯定会解决您的问题。
根据您的评论，您可以将username字段的定位符更改为以下任意一种：
<强> css_selector
driver.find_element_by_css_selector("input[name=username]")
<强> xpath
driver.find_element_by_xpath("//input[@name='username']")

有可能你的驱动程序试图在第一次加载后获取用户名字段，失败并出现异常并在重定向之前将其关闭。它需要等待。你可以尝试：
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
...
def test_worked2(self):
driver = self.driver
driver.get(base_url)
WebDriverWait(self.driver, 10).until(EC.presence_of_element_located((By.NAME, 'username'))).send_keys("xxx")

我能够通过使用Firefox配置文件来解决这个问题，我不知道它有什么不同，但它确实有效。
创建Firefox个人资料的链接
http://kb.mozillazine.org/Creating_a_new_Firefox_profile_on_Windows
以下是代码
from selenium import webdriver
fp = webdriver.FirefoxProfile('C:/Users/<user name>/AppData/Roaming/Mozilla/Firefox/Profiles/abc3defghij2.ProfileName')
driver = webdriver.Firefox(fp)
driver.get("https://www.example.com/membersarea")
