| 云函数处理 WebSocket 长连接 |
{{ $frontmatter.title }}
特殊函数名 websocket
如果需要使用 WebSocket 需要创建一个云函数并且命名为 __websocket__,这个云函数并不会运行之后销毁,会一直存在,专为 WebSocket 存在的云函数!
以下是云函数中处理 WebSocket 示例:
export async function main(ctx: FunctionContext) {
if (ctx.method === "WebSocket:connection") {
ctx.socket.send('hi connection succeed')
}
if (ctx.method === 'WebSocket:message') {
const { data } = ctx.params;
console.log(data.toString());
ctx.socket.send("I have received your message");
}
}
更多用法请参考: https://github.com/websockets/ws
客户端 WebSocket 连接
const wss = new WebSocket("wss://your-own-appid.laf.run/__websocket__");
wss.onopen = (socket) => {
console.log("connected");
wss.send("hi");
};
wss.onmessage = (res) => {
console.log("收到了新的信息......");
console.log(res.data);
};
wss.onclose = () => {
console.log("closed");
};
