python利用网易云音乐接口搭建的音乐推荐，根据单曲歌名推荐相关用户喜爱的歌曲

一、网易云音乐的相关接口

这边我想要的数据接口有：

* 网易的搜索功能，根据歌名获取歌曲的id

* 歌曲相关的评论用户接口

* 用户的相关数据包括歌单或听歌记录，这边听歌记录的接口好像不能用，所以我就用的歌单接口

关于每个接口大家可以自己F12网易官网看看是长什么样子，网易的新接口加密方式我也是在网上找的资料。

这边就是接口部分的代码：

return res
def getPlaylistDetail(self, id):

singer = ''
for author in detail['ar']:
singer += author['name']+','
music.append({'id':detail['id'],'name':detail['name'],'singer':singer, 'playCount':musicCount[detail['id']]})
return music

二、推荐的逻辑

这边我获取这首歌的所有热门评论用户以及他们的歌单，在获取所有歌单的数据，将歌单中的所有歌曲根据歌单的听取次数、订阅人数、歌曲的听取次数等等进行加权评分，奖所有的歌曲按照分数高低选取其中前30首进行推荐

下面就是评分的代码:

from __future__ import division
import time
from NetEaseAPI import *
class musicRecom():
def getSongId(self,musicTitle):
res = NetEaseAPI().search(musicTitle)
return res['
4000
result']['songs'][0]['id']
def musicRank(self,musicDict):
maxSubCount = 0
maxLsitCount = 0
maxMusicCount = 0
for music in musicDict:
if musicDict[music]['listSubscribedCount'] > maxSubCount :
maxSubCount = musicDict[music]['listSubscribedCount']
if musicDict[music]['listCount'] > maxLsitCount :
maxLsitCount = musicDict[music]['listCount']
if musicDict[music]['musicPlayCount'] > maxMusicCount :
maxMusicCount = musicDict[music]['musicPlayCount']
for music in musicDict:
musicDict[music]['score'] = musicDict[music]['listSubscribedCount'] / maxSubCount + musicDict[music]['listCount'] / maxLsitCount + musicDict[music]['musicPlayCount'] / maxMusicCount
return sorted(musicDict.items(), key = lambda d:d[1]['score'], reverse = True)

三、界面

为了可以方便输入某首歌名从而进行推荐，我写了一个简单的操作界面，tkinter库，比较丑，这个库不怎么会用，没有怎么写过界面

界面以及事件代码：

from __future__ import division
from Tkinter import *
import Tkinter
import ttk
from musicRecom import *
import threading
class GUI(Frame):
def __init__(self, master = None):
Frame.__init__(self, master)
self.pack()
self.create()
def progress(self,count1,count2):
self.len1.set(count1)
self.len2.set(count2)
def search(self):
musicTitle = self.musicTitle.get()
if musicTitle == '':
print "Please input the music title!"
else:
self.len1 = StringVar()
self.len2 = StringVar()
self.scale1 = Scale(self,from_ = 0,
to = 100,
resolution = 0.1,
orient = HORIZONTAL,
variable = self.len1,
length = 500
).grid(row = 2,column=0, columnspan=4, padx = 5)
self.scale2 = Scale(self,from_ = 0,
to = 100,
resolution = 0.1,
orient = HORIZONTAL,
variable = self.len2,
length = 500
).grid(row = 3,column=0, columnspan=4, padx = 5)
threading.Thread(target = self.musicRecom).start()
def musicRecom(self):
self.searchButton.destroy()
musicTitle = self.musicTitle.get()
res = dict()
songId = musicRecom().getSongId(musicTitle)
time.sleep(1)
comment = NetEaseAPI().getComment(songId)
time.sleep(1)
count1 = 0
for user in comment:
count1 = count1 + 1
uid = user['user']['userId']
playlist = NetEaseAPI().getPlaylist(uid)
time.sleep(1)
count2 = 0
for table in playlist:
count2 = count2 + 1
musicDetail = NetEaseAPI().getPlaylistDetail(table['id'])
time.sleep(1)
self.progress(count1/len(comment)*100,count2/len(playlist)*100)
for music in musicDetail:
res[music['id']]={'id':music['id'],'name':music['name'],'singer':music['singer'],'musicPlayCount':int(music['playCount']),'listCount':int(table['playCount']),'listSubscribedCount':int(table['subscribedCount'])}
self.res = musicRecom().musicRank(res)
self.maxPage = 4
self.page = 1
self.nextButton = Button(self, text='Pre', command=self.Pre)
self.nextButton.grid(row = 4,column = 1, padx=5, pady=5)
self.nextButton = Button(self, text='Next', command=self.Next)
self.nextButton.grid(row = 4,column = 2, padx=5, pady=5)
self.frame = Frame(self)
self.frame.grid(row = 5,columnspan=4)
self.getCont()
def getCont(self):
index = 1
num = 0
self.frame.destroy()
self.frame = Frame(self)
self.frame.grid(row = 5,columnspan=4)
for item in self.res:
num = num + 1
if num > self.page * 15:
break
if num <= self.page * 15 and num > (self.page - 1) * 15:
Label(self.frame, text=index + (self.page - 1) * 15).grid(row = index + 4,column=0)
Label(self.frame, text=item[1]['name'].encode('utf8')).grid(row = index + 4,column=1)
Label(self.frame, text=item[1]['id']).grid(row = index + 4,column=2)
Label(self.frame, text=item[1]['singer'].encode('utf8')).grid(row = index + 4,column=3)
index = index + 1
def Next(self):
if self.page < self.maxPage:
self.page = self.page + 1
else:
self.page = 1
self.getCont()
def Pre(self):
if self.page > 1:
self.page = self.page - 1
else:
self.page = self.maxPage
self.getCont()
def create(self):
self.labelName = Label(self, text = "Please input the music name:")
self.labelName.grid(row = 0, column = 0)
self.musicTitle = StringVar()
self.inputName = Entry(self, textvariable = self.musicTitle, width=50)
self.inputName.grid(row = 0, column = 1, columnspan=3, padx=5, pady=5)
self.searchButton = Button(self, text='Search', command=self.search)
self.searchButton.grid(row = 1,column = 1, padx=5, pady=5)

四、主调度

#!/usr/bin/env python
# -*- coding: UTF-8 -*-

# from Crawler import *
import sys
from GUI import *
default_encoding = 'utf-8'
if sys.getdefaultencoding() != default_encoding:
reload(sys)
sys.setdefaultencoding(default_encoding)

def main():
root = Tkinter.Tk()
app = GUI(root)
root.geometry('640x560')
root.resizable(False, False)
app.master.title('网易云音乐的歌曲推荐')
app.mainloop()

if __name__ == "__main__":
main()

五、测试结果
