🎈🎈作者主页: 喔的嘛呀🎈🎈 🎈🎈所属专栏:python爬虫学习🎈🎈 ✨✨谢谢大家捧场,祝屏幕前的小伙伴们每天都有好运相伴左右,一定要天天开心哦!✨✨ 目录 helllo,兄弟姐妹们!今天我们接着把第二十二天剩下的十个知识点学完(从第十个开始)。 十、处理动态内容 处理动态加载内容的常见方法是通过模拟用户操作来触发页面加载新内容。对于需要滚动页面加载的情况,可以使用 Selenium 的 execute_script 方法来执行 JavaScript 代码,从而实现滚动页面的效果。下面是一个示例代码,演示如何使用 Selenium 模拟滚动页面来加载更多内容: from selenium import webdriver import time # 启动浏览器 driver = webdriver.Chrome() # 打开网页 driver.get('<https://example.com>') # 模拟滚动页面 scroll_pause_time = 2 # 每次滚动后等待时间 screen_height = driver.execute_script("return...

Bridging Code and Security: Unveiling the Power of DevSecOps
Introduction In the realm of software development, DevOps has revolutionized the way teams create, deploy, and maintain applications, blending development (Dev) and operations (Ops) to improve agility and efficiency. Traditionally, while DevOps enhanced collaboration and speed, security often lagged behind, treated as a checkpoint rather than a core component. This oversight has become increasingly problematic in an era where digital threats are both more sophisticated and more damaging.

centos 安装 ffmpeg 6.1.1 并添加 libx264库
ffmpeg 写在前面,我们为什么要安装 x264 因为对于两个不同的.mp4视频来说,虽然它们的后缀名是一样的,但是两个MP4视频采用的编码格式可能是不一样的,它们可以采用H.264或H.265的编码格式进行编码,也可以采用MPEG-4的编码方式。而对于MP4视频文件的播放,Chrome只支持标准的H.264方式编码。因此如果MP4视频的编码格式不是H.264,那么这个视频文件就无法正常播放~ 那么,为什么Chrome只支持H.264这种编码方式而不支持所有的视频编码方式呢?Google查了一下,网上给出的原因主要是说因为绝大部分的视频编码格式都要付专利费的,Google已经购买了H.264编码格式,而其它的就没有购买了,因此如果一个MP4视频不是H.264格式的,那么Chrome也是不支持播放的~ 软件版本: ffmpeg version 6.1.1 Copyright © 2000-2023 the FFmpeg developers NASM version 2.14 compiled on Feb 1 2024 x264 0.164.3173 4815cca...
