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)
})
}
};
