如何使用Selenium Python在Chromedriver中管理/警报消息

我正在使用Selenium从网站获取磁铁链接，但当我单击Chrome Webdriver链接时，它会询问我是否要在uTorrent（打开uTorrent？）中打开磁铁链接，该警报有两个按钮，

打开uTorrent

和

取消

，如图所示

我想知道如何管理

1-如果我可以发送按键，请按chrome上的

左箭头

和

回车

，然后将链接发送到“自动更新”

2-以某种方式使用selenium获取/接收警报，然后按“打开自动更新”

alert=Driver.Alerts（）。单击OK（）

3-更改Chrome webdriver的设置以禁用此警报，并发送所有没有警报的链接

4-或任何其他想法

所有这些都是用Python实现的。在Windows10上使用ChromeWebDriver

######### here is my attempt to manage the alert/notification
alert = driver.switchTo().alert();
alert.send_keys(Keys.ARROW_LEFT)
print("Left")
alert.send_keys(keys.ENTER)
print("ENTER")

print('Send it to uTorrent')
t.sleep(10)
# Close the tab with URL B
driver.close()
######### 

这是完整的代码

它可能不是您想要的，但您可以将磁铁链接保存为字符串，然后使用在torrernt客户端中打开它：

os.startfile（磁铁链接）

设置意外警报行为可能有助于。。。注意：“notify”仅表示抛出异常，这发生在下一个webdriver操作发生之前：（在ChromeDriver选项中设置）

alert = driver.switch_to_alert()
alert.accept()
