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：
