Reconnection of Client when server reboots in WebSocket

Question

I am using web socket using PHP5 and the Chrome browser as client. I have taken the code from the site http://code.google.com/p/phpwebsocket/.

I run the server, and

Answer 1

Finally, I make ws auto reconnect in vue+ts, similar as following:

private async mounted() {
    // Connect to WebSocket
    const sn = "sb1234567890";
    const host =
        window.location.protocol == "https:"
            ? "wss://www.xxx.net"
            : process.env.DEV_TYPE === "fullstack"
            ? "ws://10.0.0.14:8528"
            : "ws://www.xxx.net:8528";
    const wsUri = host + "/feed-home/" + sn;
    await this.startWs(wsUri, sn);
    // !!!Deprecated: failed to reconnect
    // let ws = new WebSocket();
    // console.log(ws);
    // ws.onopen = async function(event) {
    //     console.log(event, "openEvent");
    //     clearInterval(that.timer);
    // };
    // ws.onclose = async function(event) {
    //     console.log(event, "close");
    //     that.timer = setInterval(() => {
    //         console.log("Heart Beat");
    //         ws.send("HeartBeat");
    //         // ws = new WebSocket("ws://10.0.0.14:8528/feed-home/" + sn);
    //         console.log(ws);
    //     }, 60000);
    // };
    // ws.onmessage = async function(event) {
    //     console.log(event, "ws");
    //     alert("get it!");
    //     await alert("please update!");
    //     await that.getHome(sn);
    // };
}
private wsReconnected: boolean = false; // check whether WebSocket is reconnected
private async startWs(uri: string, sn: string) {
    let that = this;
    let ws = new WebSocket(uri);
    ws.onopen = async () => {
        if (that.wsReconnected) {
            await that.getHome(sn); // Refresh api data after reconnected
        }
        ws.send("Current client version: " + window.version);
    };
    ws.onmessage = async evt => {
        await that.getHome(sn);
        that.$message({
            type: "success",
            message: evt.data,
            showClose: true,
            center: true,
            duration: 20 * 1000
        });
    };
    ws.onclose = async () => {
        that.wsReconnected = true;
        await that.startWs(uri, sn);
        const sleep = (seconds: number) => {
            return new Promise(resolve =>
                setTimeout(resolve, seconds * 1000)
            );
        };
        await sleep(10); // Try to reconnect in 10 seconds
        // !!!Deprecated: Use timer will cause multiply ws connections
        // if (!that.wsTimer) {
        //     // Try to reconnect in 10 seconds
        //     that.wsTimer = setInterval(async () => {
        //         console.log("reconnecting websocket...");
        //         await that.startWs(uri, sn);
        //     }, 10 * 1000);
        // }
    };
}
