此文为python爬虫文章，讲了用python爬取某狗里的歌名并下载（包括vip）后面带exe

2020/8/5

由于本人爬虫经验不足，代码可能会粗糙，有bug，麻烦大佬加个微信QQ一起学吧！代码失效了也给我通知一声（图片如果显示不出来的话请多次刷新，若问题仍存在，请告诉我换源）

老规矩
配置好python
配置好pycharm
再安装依赖的模块：
点这里（感谢大神的文章）
接下来，按下win+R输入cmd-回车！在窗口里输入

1
pip install requests selenium

打开pycharm，
新建项目，（不会的话点这里）
进去后，右键文件夹，

输入个你喜欢的名字，回车！

开始写代码吧！
先打开浏览器
访问某狗音乐下载（不要用ie）
在这里插入图片描述

随便搜索搜索看看网址
以《癞蛤蟆》为例
网址是

1
https://music.liuzhijin.cn/?name=癞蛤蟆&type=kugou

所以搜索的格式是

1
https://music.liuzhijin.cn/?name=歌曲名&type=kugou

好，咱先爬：

from selenium import webdriver
import time

name = input(">")
url = "https://music.liuzhijin.cn/?name=" + name + "&type=kugou"
browser = webdriver.Firefox()
browser.get(url)

这个网站有一点问题，底下有个载入更多，不能直接全部加载，
没有事的。。
按下F12
在出来的控制台的左上角点这个按钮
在这里插入图片描述
点击载入更多

ok，浏览器会定位到这样一条元素，

1
<div class="aplayer-more">载入更多</div>

右击-复制-完整的XPath（火狐是XPath）

time.sleep(3)
while True:
    try:
        browser.find_element_by_xpath("你的XPath").click()
    except:
        break

我的是/html/body/section/div[1]/div/form[2]/div[4]/div/div[4]

一切就绪，获取网页源代码

html = browser.page_source

控制台上看一看

看到一大堆li

现在网站上酷狗失效了（网站上失效的，网站复原了，代码应该也有效）不过网易云还能用，网易云伺候！
写本文时 selenium版本3.141.0

2023/7/28 更新

现在代码仍可用，目前selenium版本4.10.0，火狐115.0.3 (32 位)，geckodriver版本0.33.0放于源码目录下运行，本代码应该不能下载vip曲目，望了解。
