浏览器自动化测试时无法打开浏览器,提示无法连接,浏览器版本过低 Selenium、DrissionPage、cdp4j、Puppeteer、Playwright 问题
引言 使用 Selenium、Selenium Grid、DrissionPage、cdp4j、Puppeteer、Playwright 等自动化测试浏览器的时候,在 Windows 11 可能会出现无法连接浏览器、或出现错误提示:Unable to connect to the chrome remote debugging server localhost 9222。通常表示客户端尝试连接 Chrome 浏览器的远程调试端口 (通常是 9222),但未能成功连接。这可能有几种原因: Chrome 未启动或未能:Chrome 浏览器可能没有启动,或者没有以启用远程调试模式启动。 端口未开放:Chrome 可能没有监听端口 9222 或者被防火墙阻止。 其他进程占用端口:端口 9222 可能被其他进程占用。 网络问题:网络配置或本地主机名解析问题。 其他:检查一下浏览器继续后台运行是否关闭,例如:Chrome 在 设置 - 系统 - 关闭 Google Chrome 后继续运行后台应用;Edge 是在 设置 - 系统和性能 - 在 Microsoft Edge...
Upgrading an old laptop Coolpad using RPi Pico and Python
Things used in this project × 1 × 1 × 1 × 1 I had an old laptop Coolpad that I bought about 10 years ago. In addition to adding an RGB light to it, I thought to myself how nice it would be if the laptop could automatically control the coolpad. So therefore, I went through the following steps. I used the psutil and gputil libraries in Python to extract the laptop hardware information, you can see the python script below.
最细节的Flask+echarts+mysql+自动刷新升级版(websocket)_flask echarts mysql_寒暄的大企鹅的博客-CSDN博客
前言 本人于年初基于Flask+echarts+mysql+ajax实现了自动刷新,但由于ajax轮询的弊端(请求必须由客户端向服务端发起,然后服务端进行响应),想看ajax实现的朋友可以看我写的这篇Flask+echarts+mysql+自动刷新。现改用双向传输、推送消息方面能够做到灵活、简便、高效实现方案,即数据库收到数据立刻向客户端发送数据,无需客户端先向数据库发送请求。 一、环境准备 网上已经有许多教程,但由于websocket版本匹配和引入库版本等问题,大部分截至我发文阶段都无法直接实现,经过本人测试更改,以下为实现代码,另附上我的相关版本,以免读者走弯路,如需要查看其他版本的匹配方案,见官方文档 以下为官方包版本匹配说明: 以下为本人操作案例版本: 二、Flask+websocket 服务端app.py: from flask import Flask, render_template from flask_socketio import SocketIO, emit from threading import Lock import random...
