问题描述

运行Selenium脚本时，代码能正常执行，但Edge浏览器会自动关闭，同时控制台输出以下错误：

[19796:19404:0905/212543.583:ERROR:fallback_task_provider.cc(124)] Every renderer should have at least one task provided by a primary task provider. If a "Renderer" fallback task is shown, it is a bug. If you have repro steps, please file a new bug and tag it as a dependency of crbug.com/739782.
[19796:19404:0905/212549.269:ERROR:fallback_task_provider.cc(124)] Every renderer should have at least one task provided by a primary task provider. If a "Renderer" fallback task is shown, it is a bug. If you have repro steps, please file a new bug and tag it as a dependency of crbug.com/739782.

运行的代码如下：

from selenium import webdriver
from selenium.webdriver.common.by import By
import time

Browser=webdriver.Edge()

Browser.get("test.site")


Browser.maximize_window()

my_team=Browser.find_element(By.LINK_TEXT,'My Team').click()

time.sleep(3)

解决方法

1. 阻止浏览器自动关闭

浏览器自动关闭的核心原因是脚本执行完毕后，WebDriver会默认终止浏览器进程。只需给Edge添加detach实验选项，就能让浏览器在脚本结束后保持打开状态：

修改后的代码：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.edge.options import Options
import time

# 配置Edge保持会话不自动关闭
edge_options = Options()
edge_options.add_experimental_option("detach", True)

# 传入配置初始化浏览器
Browser = webdriver.Edge(options=edge_options)

Browser.get("test.site")
Browser.maximize_window()

Browser.find_element(By.LINK_TEXT, 'My Team').click()

time.sleep(3)
