喜欢的歌曲不在一个平台怎么办？你需要一个自己专属的音乐播放器c/c++qq46614154的博客-

前言

网易云音乐，QQ音乐，酷狗音乐，是我们经常会用到的音乐软件，当然有时候我们因为一首歌，需要在各大音乐平台上跳转，那么我们完全可以使用python自己打造一款音乐播放器

知识点：
1.python基础知识
2.requests库
3.time
4.pygame
5.tkinter
6.线程

环境:

windows + pycharm + python3

适合零基础的同学

1、导入工具

 from PyQt5 import QtWidgets,QtGui,QtCore from PyQt5.QtMultimedia import QMediaContent,QMediaPlayer import qtawesome as qta import requests,traceback

2、创建一个类

 class Music(QtWidgets.QMainWindow):     def __init__(self):         super().__init__()         # 窗口大小         self.setFixedSize(400,200)         # 标题         self.setWindowTitle("Mark")         # 初始化界面         self.init_ui()         # 设置样式         self.custom_style()         #         self.playing = False # 播放状态初始化为否         self.player = QMediaPlayer(self)          self.timer = QtCore.QTimer()         self.timer.setInterval(1000)         self.timer.start()         self.timer.timeout.connect(self.check_music_status)

3、设置样式

 def custom_style(self):         self.setStyleSheet('''             #main_widget{                 border-radius:5px;             }             #play_btn,#pervious_btn,#next_btn{                 border:none;             }             #play_btn:hover,#pervious_btn:hover,#next_btn:hover{                 background:gray;                 border-radius:5px;                 cursor:pointer;             }         ''')         self.close_btn.setStyleSheet('''             QPushButton{                 background:#F76677;                 border-radius:5px;                 }             QPushButton:hover{                 background:red;                 }''')         self.status_label.setStyleSheet('''             QLabel{                 background:#F7D674;                 border-radius:5px;                 }         ''')

4、初始化UI界面

 def init_ui(self):         # 窗口布局         self.main_widget = QtWidgets.QWidget()         self.main_widget.setObjectName("main_widget")         self.main_layout = QtWidgets.QGridLayout()         self.main_widget.setLayout(self.main_layout)          # 标题         self.title_lable = QtWidgets.QLabel("乐者，音之所由生也")          # 关闭按钮         self.close_btn = QtWidgets.QPushButton("")  # 关闭按钮         self.close_btn.clicked.connect(self.close_btn_event)         self.close_btn.setFixedSize(15,15)          # 音乐状态按钮         self.status_label = QtWidgets.QLabel("")         # self.swith_btn.clicked.connect(self.swith_background)         self.status_label.setFixedSize(15,15)          # 播放按钮         play_icon = qta.icon("fa.play-circle",)         self.play_btn = QtWidgets.QPushButton(play_icon,"")         self.play_btn.setIconSize(QtCore.QSize(80, 80))         self.play_btn.setFixedSize(82,82)         self.play_btn.setObjectName("play_btn")         self.play_btn.clicked.connect(self.play_music)          # 下一首按钮         next_icon = qta.icon("fa.play-circle-o")         self.next_btn = QtWidgets.QPushButton(next_icon,"")         self.next_btn.setIconSize(QtCore.QSize(80,80))         self.next_btn.setFixedSize(82,82)         self.next_btn.setObjectName("next_btn")         self.next_btn.clicked.connect(self.next_music)          # 进度条         self.process_bar = QtWidgets.QProgressBar()         self.process_value = 0         self.process_bar.setValue(self.process_value)         self.process_bar.setFixedHeight(5)         self.process_bar.setTextVisible(False)          self.main_layout.addWidget(self.close_btn,0,0,1,1)         self.main_layout.addWidget(self.title_lable,0,1,1,1)         self.main_layout.addWidget(self.status_label,1,0,1,1)         self.main_layout.addWidget(self.play_btn, 1, 1, 1, 1)         self.main_layout.addWidget(self.next_btn, 1, 2, 1, 1)         self.main_layout.addWidget(self.process_bar,2,0,1,3)          self.setCentralWidget(self.main_widget)          # self.setWindowOpacity(0.9) # 设置窗口透明度         # self.setAttribute(QtCore.Qt.WA_TranslucentBackground)  # 设置窗口背景透明         self.setWindowFlag(QtCore.Qt.FramelessWindowHint)  # 隐藏边框

5、播放器各功能设置

 # 关闭程序     def close_btn_event(self):         self.close()      # 鼠标长按事件     def mousePressEvent(self, event):         if event.button() == QtCore.Qt.LeftButton:             self.m_drag = True             self.m_DragPosition = event.globalPos() - self.pos()             event.accept()             self.setCursor(QtGui.QCursor(QtCore.Qt.OpenHandCursor))      # 鼠标移动事件     def mouseMoveEvent(self, QMouseEvent):         if QtCore.Qt.LeftButton and self.m_drag:             self.move(QMouseEvent.globalPos() - self.m_DragPosition)             QMouseEvent.accept()      # 鼠标释放事件     def mouseReleaseEvent(self, QMouseEvent):         self.m_drag = False         self.setCursor(QtGui.QCursor(QtCore.Qt.ArrowCursor))      # 播放音乐     def play_music(self):         try:             # 播放音乐             if self.playing is False:                 self.playing = True # 设置播放状态为是                 self.play_btn.setIcon(qta.icon("fa.pause-circle")) # 设置播放图标                 player_status = self.player.mediaStatus() # 获取播放器状态                 # print("当前播放状态：",player_status)                 if player_status == 6:                     # 设置状态标签为绿色                     self.status_label.setStyleSheet('''QLabel{background:#6DDF6D;border-radius:5px;}''')                     self.player.play()                 else:                     self.next_music()             # 暂停音乐             else:                 # 设置状态为蓝色                 self.status_label.setStyleSheet('''QLabel{background:#0099CC;border-radius:5px;}''')                 self.playing = False                 self.play_btn.setIcon(qta.icon("fa.play-circle"))                 self.player.pause()         except Exception as e:             print(repr(e))      # 下一首音乐     def next_music(self):         try:             # 设置状态为黄色             self.status_label.setStyleSheet('''                 QLabel{                     background:#F7D674;                     border-radius:5px;                     }             ''')             self.playing = True  # 设置播放状态为是             self.play_btn.setIcon(qta.icon("fa.pause-circle"))  # 修改播放图标             self.process_value = 0  # 重置进度值              # 获取网络歌曲             self.get_music_thread = GetMusicThread()             self.get_music_thread.finished_signal.connect(self.init_player)             self.get_music_thread.start()         except Exception as e:             print(traceback.print_exc())      # 设置播放器     def init_player(self,url):         # print("获取到音乐链接：",url)         content = QMediaContent(QtCore.QUrl(url))         self.player.setMedia(content)         self.player.setVolume(50)         self.player.play()         self.duration = self.player.duration()  # 音乐的时长         # 设置状态为绿色         self.status_label.setStyleSheet('''             QLabel{                 background:#6DDF6D;                 border-radius:5px;                 }         ''')          # 进度条计时器         self.process_timer = QtCore.QTimer()         self.process_timer.setInterval(1000)         self.process_timer.start()         self.process_timer.timeout.connect(self.process_timer_status)      # 定时器     def check_music_status(self):         player_status = self.player.mediaStatus()         player_duration = self.player.duration()         # print("音乐时间：",player_duration)         # print("当前播放器状态",player_status)         if player_status == 7:             self.next_music()          if player_duration > 0:             self.duration = player_duration      # 进度条定时器     def process_timer_status(self):         try:             if self.playing is True:                 self.process_value += (100 / (self.duration/1000))                 # print("当前进度：",self.process_value)                 self.process_bar.setValue(self.process_value)         except Exception as e:             print(repr(e))

运行代码， 效果如下图：
