Question

我有一个字符串列表，我希望使用selenium和Python 2.7x在密码字段中输入。以下是我的代码：

# album is a URL
def password_attempt(album):
    fp = webdriver.FirefoxProfile()
    fp.set_preference("network.proxy.type", 1)
    fp.set_preference("network.proxy.socks", "127.0.0.1")
    fp.set_preference("network.proxy.socks_port", 9150)
    fp.update_preferences()
    driver = webdriver.Firefox(firefox_profile=fp)
    driver.get(album)
    elem = driver.find_element_by_name("pwd")
    for password in password_list:
        elem.send_keys(password)
        elem.send_keys(Keys.RETURN)
        if album in driver.current_url:
            continue
        else:
            return driver.current_url

此代码无法运行，并且在运行时会返回错误。实质上，当输入列表中的密码时，如果密码不正确，页面只会使用与词干相同的URL和URL末尾的几个随机字符重新加载。然后，我想继续查看列表中的下一个密码并尝试一下。如果确实接受了密码，则该页面会重定向到新网页，其中包含的新网址不包含原始网址中的任何内容。

因此原始网址可能为http://www.myalbum.com，如果输入的密码不正确，则会重定向到http://www.myalbum.com/id=12344。但是，如果输入了正确的密码，则会重定向到http://www.abc124.com

任何帮助？

更新：我重新构建了我的代码，如下所示：

for password in password_list:
    elem = driver.find_element_by_name("pwd")
    elem.send_keys(password)
    elem.send_keys(Keys.RETURN)
    if album in driver.current_url:
        continue
    else:
        return driver.current_url

错误的一部分如下：
