如何使用PyQT在图形用户界面中播放MP3

from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
from PyQt5.QtMultimedia import QMediaPlayer, QMediaContent
from PyQt5.QtCore import QUrl

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("MP3 Player")

        self.button = QPushButton("Play", self)
        self.button.clicked.connect(self.play_mp3)
        self.setCentralWidget(self.button)

    def play_mp3(self):
        # 在这里编写播放MP3的代码

def play_mp3(self):
    player = QMediaPlayer()
    media = QMediaContent(QUrl.fromLocalFile("path/to/mp3/file.mp3"))
    player.setMedia(media)
    player.play()

if __name__ == "__main__":
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()
