client.join()导致ReferenceError:未定义窗口

Question

我想使用AgoraRTC SDK开发React和Next.js的视频通话应用程序。

AgoraRTC.createClient((、AgoraRTC.createStream((、client.int((都是成功的。

但是，client.join((不成功，并且发生了以下错误。

ReferenceError: window is not defined

根据我的消息来源，以下条件分支解决了这个错误，但这些方法没有解决它

if (process.browser) {}

或

if (typeof window !== "undefined") {}

脚本如下。

import React, { useEffect } from 'react'
import styled from 'styled-components'
import { useLocation } from 'react-router-dom'
import AgoraRTC from 'agora-rtc-sdk'
import { RtcTokenBuilder, RtcRole } from 'agora-access-token'
const Live: React.FC = () => {
const appID = "**********";
const channelName = '**********';
const user_id = useLocation().search.substr(6);
useEffect(() => {
async () => {
const token = await function(){
const appCertificate = "**********";
const role = RtcRole.PUBLISHER;
const expirationTimeInSeconds = 36000;
const currentTimestamp = Math.floor(Date.now() / 1000);
const privilegeExpiredTs = currentTimestamp + expirationTimeInSeconds;
const token = RtcTokenBuilder.buildTokenWithUid(appID, appCertificate, channelName, user_id, role, privilegeExpiredTs);
return token
};

let client = AgoraRTC.createClient({
mode: "rtc",
codec: "vp8",
});

let localStream = AgoraRTC.createStream({
audio: false,
video: true,
});
client.init(appID);
client.join(token(), channelName, user_id, (uid) => {
localStream.init(()=>{
localStream.play("me");
client.publish(localStream, handleError);
}, handleError);
client.on("stream-added", function(evt){
client.subscribe(evt.stream, handleError);
});
client.on("stream-subscribed", function(evt){
let stream = evt.stream;
let streamId = String(stream.getId());
addVideoStream(streamId);
stream.play(streamId);
});
client.on("stream-removed", function(evt){
let stream = evt.stream;
let streamId = String(stream.getId());
stream.close();
removeVideoStream(streamId);
});
client.on("peer-leave", function(evt){
let stream = evt.stream;
let streamId = String(stream.getId());
stream.close();
removeVideoStream(streamId);
});
}, handleError);
}
});
return (
<Container>
<div id="me"></div>
<div id="container"></div>
</Container>
);
};
const Container = styled.div`
...
`
export default function Index(){
return (
<div>
<Live />
</div>
);
}

看起来next.js确实在尝试进行SSR。

关于这个问题，有一些很好的答案，你都试过了吗？
