在我的反应应用程序中使用SC.stream,我只是试图从soundcloud API播放一首曲目.这是我的代码：
SC.initialize({
client_id: '12xxx' // my client ID
});
//[...]
console.log(this.props.track.trackId); // I get here successfully the trackId from the song I'd like to play
SC.stream('/tracks/'+this.props.track.trackId,function(track){
track.play();
console.log(track); // I successfully get the track object here. playState attribute is on 1
});
不幸的是,曲目从未开始播放.我在控制台中没有错误.
编辑：问题仅在Chrome上,它在firefox和safari上完美运行.我现在更加困惑.
编辑2：它似乎与不在Chrome上运行的HTML5播放器相关联：当您在chrome：// plugins /重新启用Flash播放器时,通过选中“始终允许运行”,它可以正常工作
解决方法
当你有track.play()时,我不确定代码中的“track”是什么意思.如果它是音频div那么这应该有帮助.
class PlayerCtrlRender extends React.Component {
render() {
let index = this.state.playIndex;
let currentTrack = this.state.randomOn ? this.state.shuffledQueue[index] : this.props.queue[index];
let source = 'http://192.168.0.101:3950/play/' + currentTrack.location;
let title = currentTrack.title;
let progressData = {count: this.state.progressCount * 100,index: this.state.progressIndex * 100};
return (
<div id='PlayerCtrlSty' style={PlayerCtrlSty}>
<div className='FlexBox'>
<div style={timerLeftSty}>{this.state.progressIndex}</div>
<PlayerActions playing={this.state.isPlaying} clickHandler={this.clickHandler}/>
<div style={timerRightSty}>{this.state.progressCount}</div>
</div>
<JProgressBar data={progressData} position='none' />
<div id="title" style={{textAlign: 'center'}}>{title}</div>
<audio
ref="audioDiv"
src={source}
onDurationChange={this.onDurationChange}
onTimeUpdate={this.onTimeUpdate}
onEnded={this.nextSong}
/>
</div>
);
}
}
export default class PlayerCtrl extends PlayerCtrlRender {
constructor() {
super();
this.state = {
playIndex: 0,queueLength: 1,isPlaying: false,progressCount: 0,progressIndex: 0,shuffledQueue: [{title: '',location: ''}],randomOn: false
};
}
componentDidMount = () => {
let queue = knuthShuffle(this.props.queue.slice(0));
this.setState({queueLength: queue.length,shuffledQueue: queue});
this.refs.audioDiv.volume = .1;
}
clickHandler = (buttonid) => {
this.refs.audioDiv.autoplay = false;
switch (buttonid) {
case 'play': this.refs.audioDiv.play(); this.setState({isPlaying: true}); break;
case 'pause': this.refs.audioDiv.pause(); this.setState({isPlaying: false}); break;
case 'back': this.refs.audioDiv.currentTime = 0; break;
case 'next': this.nextSong(); break;
case 'random': this.refs.audioDiv.autoplay = this.state.isPlaying;
this.setState({randomOn: !this.state.randomOn}); break;
}
}
nextSong = () => {
this.refs.audioDiv.autoplay = this.state.isPlaying;
this.refs.audioDiv.currentTime = 0;
let newIndex = this.state.playIndex + 1;
if (newIndex == this.state.queueLength) newIndex = 0;
this.setState({playIndex: newIndex});
}
onDurationChange = () => {
let duration = this.refs.audioDiv.duration;
duration = getTime(Math.floor(duration));
this.setState({progressCount: duration})
this.setState({progressIndex: 0})
}

currentTime = getTime(Math.floor(currentTime));
this.setState({progressIndex: currentTime})
