const RECONNECT_INTERVAL = 5000; // 重連間隔帜消，5秒

在main.js里

// 掛載到全局
Vue.prototype.BASE_WebSocketURL = "wss://xxxxxxxxxxxxxxx/websocket/"

在App.vue里

import WebSocketService from '@/common/js/websocket.js'

    if (uni.getStorageSync('Storage_Token')) {
        let webSocketURL = this.BASE_WebSocketURL+uni.getStorageSync('Storage_Token')

        WebSocketService.createWebSocket(webSocketURL);
    } else {
        WebSocketService.closeWebSocket();
    }
},

在login.vue登錄成功

uni.setStorageSync('Storage_UserID','1846378319125213186');
const WebSocketService = require('@/common/js/websocket.js').default;
let webSocketURL = this.BASE_WebSocketURL + uni.getStorageSync('Storage_Token')

在退出登錄里

const WebSocketService = require('@/common/js/websocket.js').default;
WebSocketService.closeWebSocket();
