1.获取数据

1
2
3
keyword = '李健'
search_api = 'http://c.y.qq.com/soso/fcgi-bin/client_search_cp?ct=24&qqmusic_ver=1298&new_json=1&remoteplace=txt.yqq.center&t=0&aggr=1&cr=1&catZhida=1&lossless=0&flag_qc=0&p=1&n=50&w=' + keyword + '&jsonpCallback=searchCallbacksong2020&format=json&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq&needNewCode=0'
response = requests.get(search_api).text

即歌曲就在json.loads(response)['data']['song']['list']中

2.分析数据

首先我们来看一个解析后的url：

1
'http://streamoc.music.tc.qq.com/M800000PLHrM2luXiz.mp3?vkey=CA23BC73FA35144644BAD2C8E3026425F724AD8AA117AD079FB5812177575B59044EF642A3B422F3A9E7FEFF185839FC163444AD015BB875&guid=DreamWalkerXZ&uin=123456&fromtag=8'

然后把它的参数给分离出来

1
'http://streamoc.music.tc.qq.com/' + prefix + mid + extension + '?vkey=' + vkey + '&guid=' + guid + '&uin=' + uin + '&fromtag=8'

prefix与extension

prefix是音频格式的前缀，与extension相对应

quality	prefix	extension
dts	D00A	.flac
ape	A000	.ape
flac	F000	.flac
320	M800	.mp3
aac	C600	.m4a
ogg	O600	.ogg
128	M500	.mp3

至于如何判断是否有此品质，只需要在第一步的搜索结果中的json.loads(response)['data']['song']['list'][歌曲位置]['file']中判断size_128, size_320, size_aac, size_ape, size_dts, size_flac, size_ogg这几个项的值是否为0即可（为0则代表无此品质）

mid

mid是QQ音乐中每一首歌曲的唯一标识符

mid即json.loads(response)['data']['song']['list'][歌曲位置]['mid']的值

uin与guid

guid和uin随意填充即可, 但是要与后面生成vkey时所填的一致

vkey

vkey是一个通过算法生成的具有时效性的字符串

生成算法如下：

1
2
3
vkey = json.loads(requests.get('http://c.y.qq.com/base/fcgi-bin/fcg_music_express_mobile3.fcg?g_tk=0&loginUin=' + uin + '&hostUin=0&format=json&inCharset=utf8&outCharset=utf-8&notice=0&platform=yqq&needNewCode=0&cid=205361747&uin=' + uin + '&songmid=003a1tne1nSz1Y&filename=C400003a1tne1nSz1Y.m4a&guid=' + guid).text)['data']['items'][0]['vkey']
# 1.注意uin与guid在生成vkey和拼接直链时要一致
# 2.如果服务器在国外，请使用国内的HTTP代理来访问此接口，否则会因为版权问题无法解析
