Python网络爬虫与信息提取（12）—— 爬虫批量搜索音乐并下载模拟request请求

前言

之前模拟的是登陆浏览器获取url爬取音乐地址下载，同学改了个模拟request请求的获取下载地址，效果好多了。

代码

import requests
import json
import sys
import re


class MusicSpiwer:
    def __init__(self, music, direction="D://KuGou//"):
        self.music = music
        self.direction = direction

    def getMusicId(self):
        musicId = None
        for i in range(self.dataSource.__len__()):
            try:
                data = {"types": "search", "count": 20, "source": self.dataSource[i], "name": self.music}
                response = requests.post(

        print(filName)
        content = requests.get(musicUrl).content

            f.write(content)

    def run(self):
        musicId = self.getMusicId()
        print(musicId)
        musicUrl = self.getMusicUrl(musicId)
        print(musicUrl)
        self.writeFile(musicUrl)

if __name__ == "__main__":
    music = MusicSpiwer("出山")
    music.run()

输入音乐名字就能下载到本地啦，非常好用快来试试吧
