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

转载自：

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：

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['result']['songs'][0]['id']def musicRank(self,musicDict):maxSubCount = 0maxLsitCount = 0maxMusicCount = 0for 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'] / maxMusicCountreturn 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 = 0for user in comment:count1 = count1 + 1uid = user['user']['userId']playlist = NetEaseAPI().getPlaylist(uid)time.sleep(1)count2 = 0for table in playlist:count2 = count2 + 1musicDetail = 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 = 4self.page = 1self.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 = 1num = 0self.frame.destroy()self.frame = Frame(self)self.frame.grid(row = 5,columnspan=4)for item in self.res:num = num + 1if num > self.page * 15:breakif 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 + 1def Next(self):if self.page < self.maxPage:self.page = self.page + 1else:self.page = 1self.getCont()def Pre(self):if self.page > 1:self.page = self.page - 1else:self.page = self.maxPageself.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
