url是通过selenium IDE正确启动的，而不是通过脚本启动的。

Question

我试图启动一个url，一旦加载将提示用户名和密码。

问题是，当我通过selenium记录和运行测试用例时，它可以工作。然而，当我试图通过代码启动url时，它会变成灰色，并且不会显示任何用户名和密码提示。

观察:

当我手动打开URL时

url =http://10.131.14.245:30016/index.html

它会在几秒钟内自动重定向到

http://10.131.14.245:30016/index.html#/Login

并且用户名和密码的提示看起来是可见的。

但是，在脚本执行期间，URL没有重定向它自己，它仍然是

url =http://10.131.14.245:30016/index.html

即使我们通过代码添加‘#登录’值，它也不起作用。

我使用Python2.7 Selenium 3.6 Firefox 52.4 geckodriverv.018

Answer 1

在我看来，您所观察到的错误类型似乎是由于Selenium、geckodriver和Firefox版本之间的不匹配造成的。

正如发行说明所示，Selenium v3.6.0应该很适合geckodriver v.0.18.0 (推荐使用geckodriver v.0.19.0 )。

但是geckodriver v.0.18.0发行说明清楚地提到了以下几点：

geckodriver now recommends Firefox 53 and greater geckodriver compatible with Firefox 56 and greater

因此，将您的Firefox升级到v53+级别肯定会解决您的问题。

更新：

根据您的注释，您可以将username字段的定位器更改为以下任一项：

1. css_selector driver.find_element_by_css_selector("inputname=username")
2. xpath driver.find_element_by_xpath("//input@name='username'")

Answer 2

您的驱动程序很可能在第一次加载后获取用户名字段，异常失败并在重定向之前关闭它。它需要等待。你可以试试：

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")

Answer 3

我能够通过使用Firefox配置文件来解决这个问题，我不知道它带来了什么不同，但它实际上起了作用。

链接以创建Firefox

Windows

下面的是代码

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")
