uniapp怎么设置app自启动

import Vue from 'vue';
import App from './App';

Vue.config.productionTip = false;

// 入口文件初始化
App.mpType = 'app';
const app = new Vue(App);
app.$mount();

// 启动自启动
import APPPLUS from '@/uni_modules/app-plus/js_sdk/app-plus.js';

// plus事件配置
let vueConfig = {
    data() {
        return {
            onPlusReady: []
        };
    },
    mounted() {
        document.addEventListener('plusready', this.plusReady, false);
    },
    methods: {
        plusReady() {
            let len = this.onPlusReady.length;
            for (let i = 0; i < len; i++) {
                this.onPlusReady[i]();
            }
            this.onPlusReady = [];
        },
        onPlusReady(fn) {
            if (typeof fn === 'function') {
                if (window.plus) {
                    fn();
                } else {
                    this.onPlusReady.push(fn);
                }
            }
        }
    }
};
Vue.mixin(vueConfig);


// app自启动
app.$on('onLaunch', () => {
    APPPLUS.startupAutoLaunch(true);
});
