请教， workers 如何中转 WebSocket

我的想法：

async function handleRequest(request) { const webSocketPair = new WebSocketPair() const [client, server] = Object.values(webSocketPair) server.accept() const proxy = new WebSocket('wss://abc.com:9443'); // 这个 API 不能用 proxy.Onmessage= msg => { client.send(msg); } server.Onmessage= msg => { proxy.send(msg); } return new Response(null, { status: 101, webSocket: client }); } 

new WebSocket 抛异常了，怎么办
