項目思路解析

搜索你需要的歌名或者歌曲
抓取對應的數據包

提取json數據里的歌曲名字，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("序號", "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'] 

找到單個音樂的請求數據接口
音樂的播放地址為purl

動態提交的數據來自與同一個js文件

調試js代碼請求方法為get

get請求的url地址拼接上post對應的表單參數
因為我們獲取的數據只需要數據包含purl的req_1,只需要對應data的req_1的參數，songmid為歌曲的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) 

得到對應的req_1的數據，取出purl值拼接成歌曲播放地址
下載對應歌曲
