全部原始碼在最下面
先上效果圖
之前沒事幹，看windows10自帶的播放器有一(億)點點不順眼，然後想寫一個播放器，
正好有學了點pyqt5，然後就整了個離線播音樂放器，耗時4天，現在差不多也算是最終版本了吧，
如果接下來有時間的話也會繼續更新下去，連結：離線播放器連結
然後最近沒有事情要做，就寫了一個網路音樂播放器，結構跟離線版本差不多主要更新了邏輯，添加了爬蟲模組
快不多說，先上程式碼
首先是爬取搜尋的歌曲，歌手和url，由於要使用多執行緒，所以新開了一個類
class PAThread(QThread): # 自定義訊號物件。引數str就代表這個訊號可以傳一個字串 trigger = pyqtSignal(str) def __int__(self): # 初始化函式 super(PAThread, self).__init__() def get_info(self,url): global proxies global tryed print ('start get info') print (tryed) headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/491.10.2623.122 Safari/537.36' } web_data = requests.get(url, headers=headers) soup = BeautifulSoup(web_data.text, 'lxml') ranks = soup.select('#list > table > tbody > tr:nth-child({}) > td:nth-child(1)'.format(str(tryed))) titles = soup.select('#list > table > tbody > tr:nth-child({}) > td:nth-child(2)'.format(str(tryed))) times = soup.select('#list > table > tbody > tr:nth-child({}) > td:nth-child(6)'.format(str(tryed))) for rank, title, time in zip(ranks, titles, times): data = { 'IP': rank.get_text(), 'duan': title.get_text(), 'time': time.get_text() } q = str('http://' + str(rank.get_text()) + '/' + str(title.get_text())) proxies = { 'http': q } print(proxies)
然後就是從爬取的url下載歌曲
class WorkThread(QThread): # 自定義訊號物件。引數str就代表這個訊號可以傳一個字串 trigger = pyqtSignal(str) def __int__(self): # 初始化函式 super(WorkThread, self).__init__() def run(self): try: global number global path global downloading headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36', 'X-Requested-With': 'XMLHttpRequest'} url1 = urls[num] print(url1) os.makedirs('music', exist_ok=True) number = number +1 path = 'music\{}.mp3'.format(number) urlretrieve(url1, path) # 下載函式的使用 downloading = False self.trigger.emit(str('finish')) except: self.trigger.emit(str('nofinish'))
下面就是QListwidge的點選和播放模組
def bofang(self, num): print ('try bofang') try: import urllib global pause global songs global music global downloading downloading = True self.console_button_3.setIcon(qtawesome.icon('fa.pause', color='#F76677', font=18)) pause = False # QMessageBox.information(self, "ListWidget", "你選擇了: "+item.text())# 顯示出訊息提示框 try: pygame.mixer.stop() except: pass pygame.mixer.init() try: self.Timer = QTimer() self.Timer.start(500) except: pass try: self.label.setText('下載中')#呼叫開頭的多執行緒下載歌曲 self.work = WorkThread() self.work.start() self.work.trigger.connect(self.display) except: print ('song download error') downloading = False pass except: time.sleep(0.1) print ('system error') #self.next() pass #用於接收返回的訊號 def display(self,sd): if sd == 'finish': self.label.setText(songs[num]) print ('music\{}.mp3'.format(number)) pygame.mixer.music.load('music\{}.mp3'.format(number)) # 載入音樂 pygame.mixer.music.play() # 播放音樂 else: self.label.setText('下載錯誤')
下面是雙擊播放和上一首還有下一首
#QlistWidget的雙擊事件
def change_func(self, listwidget):
global num
item = QListWidgetItem(self.listwidget.currentItem())
print(item.text())
num = int(listwidget.currentRow())
self.label.setText(songs[num])
print(listwidget.currentRow())
self.bofang(num)
#下一首按鈕
def nextion(self):
try:
if play == 'shun':
print('shuning')
self.next()
elif play == 'shui':
print('shuiing')
self.shui()
elif play == 'always':
print('alwaysing')
self.next()
except:
print('no')
pass
下面自動播放，有迴圈，隨機和單曲迴圈，加上下一首，上一首，
#隨機播放
def shui(self):
global num
global songs
q = int(len(songs) - 1)
num = int(random.randint(1, q))
try:
print('shui')
pygame.mixer.init()
self.Timer = QTimer()
self.Timer.start(500)
# self.Timer.timeout.connect(self.timercontorl)#時間函式，與下面的進度條和時間顯示有關
self.label.setText(songs[num])
self.bofang(num) # 播放音樂
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
#單曲迴圈
def always(self):
try:
self.bofang(num)
self.label.setText(songs[num])
except:
pass
#上一首
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
下面是播放模式選擇和迴圈判斷是否要自動下一首
由於每秒鐘判斷一次，所以要使用多執行緒
'''
在init裡面的迴圈判斷開啟方法
t1 = threading.Thread(target=self.action)
t1.setDaemon(True)
t1.start()
'''
#選擇播放模式
def playmode(self):
global play
try:
if play == 'shun':
play = 'shui'
print('隨機播放')
self.label2.setText("當前為隨機播放")
try:
self.console_button_6.setIcon(qtawesome.icon('fa.random', color='#3FC89C', font=18))
print('done')
except:
print('none')
pass
# self.left_shui.setText('切換為單曲迴圈')
elif play == 'shui':
play = 'always'
print('單曲迴圈')
self.label2.setText("當前為單曲迴圈")
try:
self.console_button_6.setIcon(qtawesome.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('順序播放')
self.label2.setText("當前為順序播放")
try:
self.console_button_6.setIcon(qtawesome.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('error')
pass
#迴圈判斷
def action(self):
a = 1
global num
while a < 2:
# print ('checking')
try:
time.sleep(1)
if not pygame.mixer.music.get_busy() and pause == False and not downloading:
if play == 'shun':
print('shuning')
self.next()
elif play == 'shui':
print('shuiing')
self.shui()
elif play == 'always':
print('alwaysing')
self.always()
except:
print('no')
pass
else:
pygame.mixer.music.stop()
