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,traceback2、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：
