前言
晚上坐在電腦面前,想著一邊擼代碼,一邊聽(tīng)音樂(lè)。搜了搜自己想聽(tīng)的歌,奈何好多歌曲都提示需要版權(quán),無(wú)法播放!
沒(méi)辦法,想聽(tīng)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(lè)播放器吧~
下面,我們開(kāi)始介紹這個(gè)音樂(lè)播放器的制作過(guò)程。
一、核心功能設(shè)計(jì)
總體來(lái)說(shuō),我們首先需要設(shè)計(jì)UI界面,對(duì)播放器的畫(huà)面布局進(jìn)行排版設(shè)計(jì);其次我們的這款音樂(lè)播放器的主要功能包括根據(jù)關(guān)鍵字搜索自動(dòng)爬取音樂(lè),獲取音樂(lè)列表,能進(jìn)行音樂(lè)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(jī)播放,當(dāng)前上一首下一首播放,播放暫停開(kāi)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(jì)排版布局
頭部主要包括關(guān)鍵字搜索和音樂(lè)來(lái)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(lái)顯示播放音樂(lè)封面圖,右側(cè)用來(lái)進(jìn)行音樂(lè)列表顯示
底部主要來(lái)顯示當(dāng)前播放音樂(lè),播放進(jìn)度條,音量控制,上一首/下一首,暫停/開(kāi)始,播放方式等附加功能
關(guān)鍵字音樂(lè)列表爬蟲(chóng)
通過(guò)輸入的搜索關(guān)鍵字和選擇的音樂(lè)來(lái)源,自動(dòng)爬取對(duì)應(yīng)的音樂(lè)數(shù)據(jù)
將爬取獲取的音樂(lè)名進(jìn)行列表顯示,顯示在中間主體搜索頁(yè)
音樂(lè)播放
音樂(lè)列表中我們需要雙擊某一首歌,對(duì)爬取的歌曲封面圖和歌曲進(jìn)行下載
下載成功,對(duì)音樂(lè)文件根據(jù)播放進(jìn)度條進(jìn)行播放
附加功能
播放音樂(lè)時(shí),我們還需要有播放暫停和啟動(dòng)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(lè)列表播放方式,列表循環(huán)、單曲循環(huán)、隨機(jī)播放
二、實(shí)現(xiàn)步驟
1. UI設(shè)計(jì)排版布局
基于功能點(diǎn),我們首先考慮進(jìn)行簡(jiǎn)單的UI布局設(shè)計(jì),這里我們使用的是pyqt5。核心設(shè)計(jì)代碼如下:

2. 關(guān)鍵字音樂(lè)列表爬蟲(chóng)
我們可以根據(jù)輸入的關(guān)鍵字和音樂(lè)來(lái)源進(jìn)行音樂(lè)爬取。這里我們需要通過(guò)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(kāi)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(cuò)’) self.trigger.emit(str(‘unfinish’)) stop = False paing = False qmut.unlock()
爬取代碼寫(xiě)好了,我們還需要將爬取的這些音樂(lè)數(shù)據(jù)列表顯示到畫(huà)面中搜索頁(yè)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(méi)網(wǎng)了呀`(*>﹏<*)′,再試一遍吧~’) self.listwidget.item(0).setForeground(Qt.white)
3. 音樂(lè)播放
關(guān)鍵字搜索音樂(lè)列表完成之后,接下來(lái)我們需要實(shí)現(xiàn)音樂(lè)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(guò)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): try: global number global path global downloading try: proxies = { ‘http’: ‘http://124.72.109.183:8118’, ‘ Shttp’: ‘http://49.85.1.79:31666’

except: pass
if type == ‘kugou’ and len(aqq) - 1 == 6: aqqe = str(aqq[0]) + str(‘//’) + str(aqq[2]) + str(‘/’) + str(aqq[3]) + str(‘/’) + str( ‘400’) + str(‘/’) + str(aqq[5]) + str(‘/’) + str(aqq[6]) print(aqqe) elif type == ‘netease’ and len(aqq) - 1 == 4: aqn = aq.split(‘?’) b = ‘?param=500x500’ aqqe = (str(aqn[0]) + str(b)) print(aqqe) else: aqqe = pic[num] req = get(aqqe)
checkfile = open(str(data + ‘/ls1.png’), ‘w+b’) for i in req.iter_content(100000): checkfile.write(i)

音樂(lè)播放模塊:
def bofang(self, num, bo): print(‘嘗試進(jìn)行播放’) try: import urllib global pause global songs global music global downloading downloading = True self.console_button_3.setIcon(icon(‘fa.pause’, color=‘#F76677’, font=18)) pause = False try: mixer.stop() except: pass mixer.init() try: self.Timer = QTimer() self.Timer.start(500) except: pass try: self.label.setText(‘正在尋找文件...’) self.work = WorkThread() self.work.start() self.work.trigger.connect(self.display) except: print(‘無(wú)法播放,歌曲下載錯(cuò)誤’) downloading = False pass except: sleep(0.1) print(‘播放系統(tǒng)錯(cuò)誤’) # self.next() pass

至此,我們的音樂(lè)播放器已經(jīng)可以正常播放音樂(lè)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(jī)播放,當(dāng)前上一首下一首播放,播放暫停開(kāi)始,音量增加減少等等。
播放模式:
(1)隨機(jī)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(jī)播放下一首’) mixer.init() self.Timer = QTimer() self.Timer.start(500) # self.Timer.timeout.connect(self.timercontorl)#時(shí)間函數(shù),與下面的進(jìn)度條和時(shí)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(lè) 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(lè)
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(jī)播放’) self.label2.setText(“當(dāng)前為隨機(jī)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 = ‘a(chǎn)lways’ 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 == ‘a(chǎn)lways’: 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(jī)播放’) except: print(‘模式選擇錯(cuò)誤’) pass
播放暫停/開(kāi)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(lè)播放器就基本完成啦~ 一起來(lái)看看效果吧!
三、結(jié)束語(yǔ)
當(dāng)然這款音樂(lè)播放器還有待完善的功能尚未完成:
音樂(lè)本地下載保存
播放本地音樂(lè)
添加我喜愛(ài)的音樂(lè)功能
歌詞播放
音樂(lè)進(jìn)度跳播
后面有時(shí)間這些功能也會(huì)繼續(xù)完善下!今天我們就到這里,明天繼續(xù)努力!
