Python爬虫QQ音乐数据采取，公开数据获取案例之一

本文主要是介绍Python爬虫QQ音乐数据采取，公开数据获取案例之一，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

工具准备

数据来源: QQ音乐
开发环境：win10、python3.7
开发工具：pycharm、Chrome

效果展示

项目思路解析

搜索你需要的歌名或者歌曲
抓取对应的数据包

提取json数据里的歌曲名字，歌曲的mid，歌手名字

for i in range(1, 10):
    url = 'https://c.y.qq.com/soso/fcgi-bin/client_search_cp'
    params = {
        "ct": " 24",
        "qqmusic_ver": " 1298",
        "new_json": " 1",
        "remoteplace": " txt.yqq.song",
        "searchid": " 66595602585102401",
        "t": " 0",
        "aggr": " 1",
        "cr": " 1",
        "catZhida": " 1",
        "lossless": " 0",
        "flag_qc": " 0",
        "p": str(i),
        "n": " 10",
        "w": keyword,
        "g_tk_new_20200303": " 1390029147",
        "g_tk": " 1390029147",
        "loginUin": " 1164153961",
        "hostUin": " 0",
        "format": " json",
        "inCharset": " utf8",
        "outCharset": " utf-8",
        "notice": " 0",
        "platform": " yqq.json",
        "needNewCode": " 0"
    }


    response = requests.get(url, params=params, headers=headers)
    # print(re.findall('callback\((.*)\)', response)[0])
    search_result = eval(re.findall('callback\((.*)\)', response.text)[0])
    song_info_list = search_result['data']['song']['list']
    # print()
    tplt = "{0:<10}\t{1:<10}\t{2:<20}"
    print(tplt.format("序号", "歌手", "歌名"))
    for song_info in song_info_list:
        # print(song_info)
        song_name = song_info['songname']
        song_mid = song_info['songmid']
        singer = song_info['singer'][0]['name']

找到单个音乐的请求数据接口
音乐的播放地址为purl

动态提交的数据来自与同一个js文件

调试js代码请求方法为get

get请求的url地址拼接上post对应的表单参数
因为我们获取的数据只需要数据包含purl的req_1,只需要对应data的req_1的参数，songmid为歌曲的mid

params1 = {
            '_': time.time()*1000,
            'sign': 'zzakgej75pk8w36d82032784bdb9204d99bf6351acb7d',
            "data": '{"req":{"module":"vkey.GetVkeyServer","method":"CgiGetVkey","param":{"guid":"7469768631","songmid":["' + song_mid + '"],"songtype":[0],"uin":"1164153961","loginflag":1,"platform":"20"}}}'
        }
response = requests.get(url1, params=params1, headers=headers)

得到对应的req_1的数据，取出purl值拼接成歌曲播放地址
下载对应歌曲
