04、Python爬虫——批量爬取douyin视频，下载到本地，半个小时内解决批量下载douyin视频-海口c网

概要

针对批量爬取douyin视频分为两期进行讲解，本期（第一期）内容是讲解如何在上批量下载视频，如何快速的搭建环境，修改参数，让小伙伴们边看边学，半个小时内就可以轻松将douyin视频批量进行下载。第二期内容主要是对代码进行详解，对爬虫感兴趣的小伙伴可以深入了解一下。

代码完整版及结果展示

废话不多说直接放完整版代码，如果有小伙伴不想去研究的太深，直接拿走用就OK，参照下面我所讲解到所需要更换的参数进行修改，就可以批量下载各种各样的douyin视频啦

下面就是爬取到的结果，在代码中对成功下载的视频进行打印，然后在本地文件夹中就可以查看到所爬取到的视频（下面下载的视频只是示例，我在运行不到秒就结束了）在这里要提醒大家一下，如果在爬取时间较长的视频时，尽量在网速比较快的情况下进行爬取

具体操作流程

1、代码环境搭建

运行代码的话，就避免不了使用一个好的环境，下方这个链接中，详细介绍了搭建环境的步骤，大家可以少走弯路直接参考，大家如果根据下方链接的流程进行配置的话10分钟就可以搭建成功。

01、Python爬虫——以爬取官方医院信息为例（超详细讲解，小白完全可以看懂）_python爬取医院信息-CSDN博客https://blog.csdn.net/YCH0309/article/details/138588771?spm=1001.2014.3001.5502

2、代码简单介绍

为了能够快速的让大家掌握，并且调整参数，下面我将分成4步，快速的为大家进行介绍

1、文件的创建

第一步要在刚建立的文件夹下，创建一个Python文件，这个文件是用来存放代码的，同时在这个文件下创建一个新的文件夹，这个文件夹是用来存放下载视频的（在这里要注意一下，这个文件名称要和第四步的名称一样）

2、标头参数

大家可以看到这个标头下，有三个头，分别是Cookie、Referer和User-Agent，在这里我就不详细介绍这三个分别是什么意思了，在第二期内容中会详细进行介绍。这里就用大白话为大家说明一下这三个的作用。这三个标头大家可以理解为，当我们要回家，打开一扇门时，需要一把钥匙，这样才能够正常的进入到房间内，进行一系列的活动

在这里三个标头就是一把钥匙，当我们想要请求服务器的时候，就需要用一把钥匙来证明我们的身份，当我们的身份合法时，就可以获取里面的内容了（在这里只是简单的进行介绍，第二期会详细说明）
