真机测试音乐不能继续播放，会从开头重新播放，编辑工具测试正常

let bgAudioManager = wx.getBackgroundAudioManager(),

postId = this.data.postId,

postsData = this.data.postsData

if (this.data.isPlayingMusic) {

bgAudioManager.pause()

this.setData({

isPlayingMusic: false

})

} else {

bgAudioManager.title = postsData[postId].music.title

bgAudioManager.coverImgUrl = postsData[postId].music.coverImg

// 设置了 src 之后会自动播放

bgAudioManager.src = postsData[postId].music.url

this.setData({

isPlayingMusic: true

})

}
