先上效果图
之前没事干，看windows10自带的播放器有一(亿)点点不顺眼，然后想写一个播放器，
正好有学了点pyqt5，然后就整了个离线播音乐放器，耗时4天，现在差不多也算是最终版本了吧，
如果接下来有时间的话也会继续更新下去，链接：离线播放器链接
然后最近没有事情要做，就写了一个网络音乐播放器，结构跟离线版本差不多主要更新了逻辑，添加了爬虫模块
快不多说，先上代码
首先是爬取搜索的歌曲，歌手和url，由于要使用多线程，所以新开了一个类
class PAThread(QThread):
# 自定义信号对象。参数str就代表这个信号可以传一个字符串
trigger = pyqtSignal(str)
def __int__(self):
# 初始化函数
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)
然后就是从爬取的url下载歌曲
class WorkThread(QThread):
# 自定义信号对象。参数str就代表这个信号可以传一个字符串
trigger = pyqtSignal(str)
def __int__(self):
# 初始化函数
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) # 下载函数的使用
downloading = False
self.trigger.emit(str(‘finish‘))
except:
self.trigger.emit(str(‘nofinish‘))
下面就是QListwidge的点击和播放模块
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", "你选择了: "+item.text())# 显示出消息提示框
try:
pygame.mixer.stop()
except:
pass
pygame.mixer.init()
try:
self.Timer = QTimer()
self.Timer.start(500)
except:
pass
try:
self.label.setText(‘下载中‘)#调用开头的多线程下载歌曲
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
#用于接收返回的信号
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)) # 载入音乐
pygame.mixer.music.play()
# 播放音乐
else:
self.label.setText(‘下载错误‘)
下面是双击播放和上一首还有下一首
#QlistWidget的双击事件
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)
#下一首按钮
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
下面自动播放，有循环，随机和单曲循环，加上下一首，上一首，
#随机播放
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)#时间函数，与下面的进度条和时间显示有关
self.label.setText(songs[num])
self.bofang(num) # 播放音乐
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
#单曲循环
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
下面是播放模式选择和循环判断是否要自动下一首
由于每秒钟判断一次，所以要使用多线程
‘‘‘
在init里面的循环判断打开方法
t1 = threading.Thread(target=self.action)
t1.setDaemon(True)
t1.start()
‘‘‘
#选择播放模式
def playmode(self):
global play
try:
if play == ‘shun‘:
play = ‘shui‘
print(‘随机播放‘)
self.label2.setText("当前为随机播放")
try:
self.console_button_6.setIcon(qtawesome.icon(‘fa.random‘, color=‘#3FC89C‘, font=18))
print(‘done‘)
except:
print(‘none‘)
pass
# self.left_shui.setText(‘切换为单曲循环‘)
elif play == ‘shui‘:
play = ‘always‘
print(‘单曲循环‘)
self.label2.setText("当前为单曲循环")
try:
self.console_button_6.setIcon(qtawesome.icon(‘fa.retweet‘, color=‘#3FC89C‘, font=18))
print(‘done‘)
except:
print(‘none‘)
# self.left_shui.setText(‘切换为顺序播放‘)
elif play == ‘always‘:
play = ‘shun‘
print(‘顺序播放‘)
self.label2.setText("当前为顺序播放")
try:
self.console_button_6.setIcon(qtawesome.icon(‘fa.align-center‘, color=‘#3FC89C‘, font=18))
print(‘done‘)
except:
print(‘none‘)
# self.left_shui.setText(‘切换为随机播放‘)
except:
print(‘error‘)
pass
#循环判断
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()
