昨天晚上坐在電腦面前，想著一邊擼代碼，一邊聽音樂。搜了搜自己想聽的歌，奈何好多歌曲都提示需要版權(quán)，無法播放！
沒辦法，想聽歌還是得靠自己解決！今天就一起用python自制一款炫酷的音樂播放器吧~
首先一起來看看最終實現(xiàn)的音樂播放器效果：
下面，我們開始介紹這個音樂播放器的制作過程。
一、核心功能設(shè)計
總體來說，我們首先需要設(shè)計UI界面，對播放器的畫面布局進(jìn)行排版設(shè)計；其次我們的這款音樂播放器的主要功能包括根據(jù)關(guān)鍵字搜索自動爬取音樂，獲取音樂列表，能進(jìn)行音樂播放。
當(dāng)然還少不了一些附加功能，例如播放方式列表循環(huán)、單曲循環(huán)、隨機播放，當(dāng)前上一首下一首播放，播放暫停開始，音量增加減少，播放歷史查看等。
拆解需求，大致可以整理出核心功能如下：
UI設(shè)計排版布局
頭部主要包括關(guān)鍵字搜索和音樂來源選擇，以及窗體最小化，最大化，關(guān)閉功能
中間主體包含左右兩側(cè)，左側(cè)用來顯示播放音樂封面圖，右側(cè)用來進(jìn)行音樂列表顯示
底部主要來顯示當(dāng)前播放音樂，播放進(jìn)度條，音量控制，上一首/下一首，暫停/開始，播放方式等附加功能
關(guān)鍵字音樂列表爬蟲
通過輸入的搜索關(guān)鍵字和選擇的音樂來源，自動爬取對應(yīng)的音樂數(shù)據(jù)
將爬取獲取的音樂名進(jìn)行列表顯示，顯示在中間主體搜索頁
音樂播放
音樂列表中我們需要雙擊某一首歌，對爬取的歌曲封面圖和歌曲進(jìn)行下載
下載成功，對音樂文件根據(jù)播放進(jìn)度條進(jìn)行播放
附加功能
播放音樂時，我們還需要有播放暫停和啟動功能
音量控制提高或者降低
當(dāng)前播放歌曲上一首、下一首
音樂列表播放方式，列表循環(huán)、單曲循環(huán)、隨機播放
二、實現(xiàn)步驟
1. UI設(shè)計排版布局
基于功能點，我們首先考慮進(jìn)行簡單的UI布局設(shè)計，這里我們使用的是pyqt5。核心設(shè)計代碼如下：
def init_ui(self):
global type
self.setFixedSize(1025, 750)
self.main_widget = QWidget() # 創(chuàng)建窗口主部件
self.main_layout = QGridLayout() # 創(chuàng)建主部件的網(wǎng)格布局

self.close_widget = QWidget() # 創(chuàng)建關(guān)閉側(cè)部件
self.close_widget.setObjectName('close_widget')
self.close_layout = QGridLayout() # 創(chuàng)建左側(cè)部件的網(wǎng)格布局層
self.close_widget.setLayout(self.close_layout) # 設(shè)置左側(cè)部件布局為網(wǎng)格

實現(xiàn)效果如下：
2. 關(guān)鍵字音樂列表爬蟲
我們可以根據(jù)輸入的關(guān)鍵字和音樂來源進(jìn)行音樂爬取。這里我們需要通過多線程，將歌曲、歌手、歌曲url地址全都獲取。核心代碼如下：
def run(self):
qmut.lock()
try:
global paing
global stop
global lrcs
global urls
global songs
global name
global songid
global proxies
global pic
global tryed
paing = True
print('搜索軟件{}'.format(type))
print('開始搜索')
name = name
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.110.430.128 Safari/537.36',
'X-Requested-With': 'XMLHttpRequest'
}
urls = []
songs = []
pic = []
lrcs = []
pages = 5
print(pages)
for a in range(0, pages):
if not stop:
urlss = ['http://music.9q4.cn/', 'https://defcon.cn/dmusic/','http://www.xmsj.org/',
'http://music.laomao.me/']
print (tryed)
if tryed >3:
tryed = 0
url = urlss[tryed]
else:
url = urlss[tryed]
print (urlss[tryed])
params = {'input': name,
'filter': 'name',
'type': type,
'page': a
}
if not stop:
try:
res = post(url, params, headers=headers, proxies=proxies)
html = res.json()
for i in range(0, 10):
try:
title = jsonpath(html, '$..title')[i]
author = jsonpath(html, '$..author')[i]
url1 = jsonpath(html, '$..url')[i] # 取下載網(wǎng)址
pick = jsonpath(html, '$..pic')[i] # 取歌詞
lrc = jsonpath(html, '$..lrc')[i]
print(title, author)
lrcs.append(lrc)
urls.append(url1)
pic.append(pick)
songs.append(str(title) + ' - ' + str(author))
except:
pass
except:
stop = False
paing = False
self.trigger.emit(str('finish'))
else:
self.trigger.emit(str('finish'))
else:
self.trigger.emit(str('clear'))
pass
stop = False
paing = False
except:
print('爬取歌曲出錯')
self.trigger.emit(str('unfinish'))
stop = False
paing = False
qmut.unlock()
爬取代碼寫好了，我們還需要將爬取的這些音樂數(shù)據(jù)列表顯示到畫面中搜索頁面中。代碼如下：
def repite(self, name, type):
global tryed
global paing
global stop
self.listwidget.clear()
self.listwidget.addItem('搜索中')
self.listwidget.item(0).setForeground(Qt.white)
try:
if paing:
stop = True
self.listwidget.clear()
self.work2 = PAThread()
self.work2.start()
self.work2.trigger.connect(self.seafinish)
else:
self.work2 = PAThread()
self.work2.start()
self.work2.trigger.connect(self.seafinish)
except:
tryed = tryed + 1
get_info('https://www.kuaidaili.com/free/inha')
self.listwidget.addItem('貌似沒網(wǎng)了呀`(*>﹏<*)′,再試一遍吧~')
self.listwidget.item(0).setForeground(Qt.white)
效果如下：
3. 音樂播放
關(guān)鍵字搜索音樂列表完成之后，接下來我們需要實現(xiàn)音樂播放功能。首先需要從爬取的url下載待播放的歌曲，這里還是通過多線程進(jìn)行。核心代碼如下：
class WorkThread(QThread):
trigger = pyqtSignal(str)
def __int__(self):
# 初始化函數(shù)
super(WorkThread, self).__init__()
# 進(jìn)度條
def cbk(self, a, b, c):
'''''回調(diào)函數(shù)
@a:已經(jīng)下載的數(shù)據(jù)塊
@b:數(shù)據(jù)塊的大小
@c:遠(yuǎn)程文件的大小
'''
per = 100.0 * a * b / c
if per > 100:
per = 100
# print ('%.2f%%' % per)
self.trigger.emit(str('%.2f%%' % per))
def run(self):

for content in r.iter_content(chunk_size=1024):

至此，我們的音樂播放器已經(jīng)可以正常播放音樂了。
4. 附加功能
主要功能已經(jīng)完成了，下面我們還可以添加一些附加功能，例如播放方式列表循環(huán)、單曲循環(huán)、隨機播放，當(dāng)前上一首下一首播放，播放暫停開始，音量增加減少等等。
播放模式：
（1）隨機播放：
def shui(self):
global num
global songs
if bo == 'boing':
q = int(len(songs) - 1)
num = int(randint(1, q))
elif bo == 'love':
q = int(len(loves) - 1)
num = int(randint(1, q))
else:
q = int(len(songed) - 1)
num = int(randint(0, q))
try:
print('隨機播放下一首')
mixer.init()
self.Timer = QTimer()
self.Timer.start(500)
# self.Timer.timeout.connect(self.timercontorl)#時間函數(shù)，與下面的進(jìn)度條和時間顯示有關(guān)
if bo == 'boing':
self.label.setText(songs[num])
elif bo == 'love':
self.label.setText(loves[num])
else:
self.label.setText(songed[num])
self.bofang(num, bo) # 播放音樂
except:
pass
（2） 上一首、下一首：
def last(self):
global num
global songs
if num == 0:
print('冇')
num = len(songs) - 1
else:
num = num - 1
try:
self.bofang(num)
self.label.setText(songs[num])
except:
pass
#下一首
def next(self):
print ('nexting')
global num
global songs
if num == len(songs) - 1:
print('冇')
num = 0
else:
num = num + 1
try:
self.label.setText(songs[num])
self.bofang(num)
except:
print ('next error')
pass
（3）單曲循環(huán)：
def always(self):
try:
if bo == 'boing':
self.label.setText(songs[num])
else:
self.label.setText(songed[num])
self.bofang(num, bo) # 播放音樂
except:
pass
（4） 播放模式選擇：
def playmode(self):
global play
try:
if play == 'shun':
play = 'shui'
print('切換到隨機播放')
self.label2.setText("當(dāng)前為隨機播放")
try:
self.console_button_6.setIcon(icon('fa.random', color='#3FC89C', font=18))
print('done')
except:
print('none')
pass
# self.left_shui.setText('切換為單曲循環(huán)')
elif play == 'shui':
play = 'always'
print('切換到單曲循環(huán)')
self.label2.setText("當(dāng)前為單曲循環(huán)")
try:
self.console_button_6.setIcon(icon('fa.retweet', color='#3FC89C', font=18))
print('done')
except:
print('none')
# self.left_shui.setText('切換為順序播放')
elif play == 'always':
play = 'shun'
print('切換到順序播放')
self.label2.setText("當(dāng)前為順序播放")
try:
self.console_button_6.setIcon(icon('fa.align-center', color='#3FC89C', font=18))
print('done')
except:
print('none')
# self.left_shui.setText('切換為隨機播放')
except:
print('模式選擇錯誤')
pass
播放暫停/開始：
def pause(self):
global pause
if pause:
try:
mixer.music.unpause()
except:
pass
self.console_button_3.setIcon(icon('fa.pause', color='#3FC89C', font=18))
pause = False
else:
try:
mixer.music.pause()
except:
pass
self.console_button_3.setIcon(icon('fa.play', color='#F76677', font=18))
pause = True
音量提高/降低：
def voiceup(self):
try:
print('音量加大')
global voice
voice += 0.1
if voice > 1:
voice = 1
mixer.music.set_volume(voice)
k = Decimal(voice).quantize(Decimal('0.00'))
self.label3.setText('音量：{}'.format(str(k * 100) + '%'))
except:
pass
def voicedown(self):
try:
print('音量減少')
global voice
voice -= 0.1
if voice < 0:
voice = 0
mixer.music.set_volume(voice)
k = Decimal(voice).quantize(Decimal('0.00'))
self.label3.setText('音量：{}'.format(str(k * 100) + '%'))
except:
pass
至此，這款音樂播放器就基本完成啦~ 一起來看看效果吧！
三、結(jié)束語
當(dāng)然這款音樂播放器還有待完善的功能尚未完成：
音樂本地下載保存
播放本地音樂
添加我喜愛的音樂功能
歌詞播放
音樂進(jìn)度跳播
后面有時間這些功能也會繼續(xù)完善下！今天我們就到這里，明天繼續(xù)努力！
從推公式到寫代碼：代碼是聯(lián)系理論和現(xiàn)實的橋梁，本書通過代碼實現(xiàn)*化算法，將理論與實踐相結(jié)合，在編程中思考算法的計算過程，并通過代碼將算法應(yīng)用在實際問題中，以達(dá)到解決問題的目的。
