Python爬虫之爬取酷狗音乐歌曲
Python爬虫之爬取酷狗音乐歌曲
1.安装第三方库
在Python的语言库中, 分为Python标准库和Python的第三方库. Python标准库是在你安装Python的时候已经包含在了安装目录下, 而Python第三方库需要使用Python的包管理pip来安装. 在本次代码中, 我们需要用到request库. requests翻译成中文就是请求, 顾名思义, requests是用来模拟用户向服务器发出请求.下面我来介绍如何安装requests库:打开cmd, 输入pip install requests -i https://pypi.tuna.tsinghua.edu.cn/simple, 如果出现黄色字体, 请先执行pip install pip -U -i https://pypi.tuna.tsinghua.edu.cn/simple. 反之, 及下载成功
2.验证下载是否成功.
打开python处理器, 输入import requests, 如果没有出现异常, 即下载成功. 反之, 请检查之前的配置.

下载速度可能有点慢, 请耐心等待. 下载完成后, 歌曲回保存在C:\Users\你的用户名\Music\目录下.运行效果如下:
