前景:
框架:应用 umijs 比拟全面框架,react 栈。问题前景:对于 audio 不能自动播放,这里我就不反复了,我的问题就是在 iPhone 机(v11.3.x)上曾经点击了按钮(和页面交互了),还是报了 Unhandled Rejection (NotAllowedError): The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.
排查问题:
1. 通过一直排查,在交互上 audio.play() 是没有问题的
如下是失常播放的
<button onClick={() => {clickEgg(1)}}> 播放 </button>
const clickEgg = (index) => {let audioEle = document.getElementById('bg-music')
audioEle.play()};
报错状况, 很多状况下,咱们须要申请接口再做某个音响播放的。就是这个同步申请就报错了
<button onClick={() => {clickEgg(1)}}> 播放 </button>
let audioEle = document.getElementById('bg-music')
const clickEgg = async (index) => {
// 这里有个申请
const isLogin = await getIsLoginAsync().catch(err => {setShowLoginDialog(true)
})
if (!isLogin) {setShowLoginDialog(true)
return;
}
audioEle.play()};
解决问题:
<button onClick={() => {clickEgg(1)}}> 播放 </button>
let audioEle = document.getElementById('bg-music')
const clickEgg = async (index) => {
audioEle.muted = true
let p = audioEle.play()
audioEle.currentTime = 0;
// 这里有个申请
const isLogin = await getIsLoginAsync().catch(err => {setShowLoginDialog(true)
})
if (!isLogin) {setShowLoginDialog(true)
return;
}
// 为了兼容 iphone
if (p !== undefined) {p.then(() => {
audioEle.muted = false
audioEle.pause()
setTimeout(() => {audioEle.play()
}, 0)
}).catch((e) => {console.log(e)
})
}
};
