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：

defrun(self):

qmut.lock()

try:

globalpaing

globalstop

globallrcs

globalurls

globalsongs

globalname

globalsongid

globalproxies

globalpic

globaltryed

paing=True

print('搜索軟件{}'.format(type))

print('開始搜索')

name=name

headers={

'User-Agent':'Mozilla/5.0(WindowsNT10.0;Win64;x64)AppleWebKit/537.36(KHTML,likeGecko)Chrome/121.110.430.128Safari/537.36',

'X-Requested-With':'XMLHttpRequest'

urls=[]

songs=[]

pic=[]

lrcs=[]

pages=5

print(pages)

forainrange(0,pages):

ifnotstop:

urlss=['/','/dmusic/','/',

'http://music.laomao.me/']

print(tryed)

iftryed3:

tryed=0

url=urlss[tryed]

else:

url=urlss[tryed]

print(urlss[tryed])

params={'input':name,

'filter':'name',

'type':type,

'page':a

ifnotstop:

try:

res=post(url,params,headers=headers,proxies=proxies)

html=res.json()

foriinrange(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：

defrepite(self,name,type):

globaltryed

globalpaing

globalstop

self.listwidget.clear()

self.listwidget.addItem('搜索中')

self.listwidget.item(0).setForeground(Qt.white)

try:

ifpaing:

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('/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行。核心代碼如下：

classWorkThread(QThread):

trigger=pyqtSignal(str)

def__int__(self):

#初始化函數(shù)

super(WorkThread,self).__init__()

#進度條

defcbk(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

ifper100:

per=100

#print('%.2f%%'%per)

self.trigger.emit(str('%.2f%%'%per))

defrun(self):

try:

globalnumber

print(aqqe)

eliftype=='netease'andlen(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')

foriinreq.iter_content(100000):

checkfile.write(i)

checkfile.close()

plan=(content_size/total_size)*100

#print(int(plan))

self.trigger.emit(str(develop))

makedirs('downloadmusic',exist_ok=True)

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：

defshui(self):

globalnum

globalsongs

ifbo=='boing':

q=int(len(songs)-1)

num=int(randint(1,q))

elifbo=='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)，與下面的進度條和時間顯示有關(guān)

ifbo=='boing':

self.label.setText(songs[num])

elifbo=='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：

deflast(self):

globalnum

globalsongs

ifnum==0:

print('冇')

num=len(songs)-1

else:

num=num-1

try:

self.bofang(num)

self.label.setText(songs[num])

except:

pass

defnext(self):

print('nexting')

globalnum

globalsongs

ifnum==len(songs)-1:

print('冇')

num=0

else:

num=num+1

try:

self.label.setText(songs[num])

self.bofang(num)

except:

print('nexterror')

pass

（3）單曲循環(huán)：

defalways(self):

try:

ifbo=='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：

defplaymode(self):

globalplay

try:

ifplay=='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)')

elifplay=='shui':

play='always'
