#鸿蒙通关秘籍#跟服务器实时通信的话用的比较多的是socket技术吧？next中简单实现一个socket 来做测试都需要哪些代码？？

import { webSocket } from '@kit.NetworkKit';
import { BusinessError } from '@kit.BasicServicesKit';

let defaultIpAddress = "ws://";
let ws = webSocket.createWebSocket();
ws.on('open', (err: BusinessError, value: Object) => {
    console.log("11111:" + JSON.stringify(value));
    ws.send("3", (err: BusinessError, value: boolean) => {
        if (!err) {
            console.log("success");
        } else {
            console.log(JSON.stringify(err));
        }
    });
});
ws.on('message', (err: BusinessError, value: string | ArrayBuffer) => {
    console.log("on message, message:" + value);
    if (value === 'bye') {
        ws.close((err: BusinessError, value: boolean) => {
            if (!err) {
                console.log("success");
            } else {
                console.log(JSON.stringify(err));
            }
        });
    }
});
ws.on('close', (err: BusinessError, value: webSocket.CloseResult) => {
    console.log("value.code + ", reason is " + value.reason);
});
ws.on('error', (err: BusinessError) => {
    console.log(JSON.stringify(err));
});
ws.connect(defaultIpAddress, (err: BusinessError, value: boolean) => {
    if (!err) {
        console.log("success");
    } else {
        console.log(JSON.stringify(err));
    }
});
