3 修改路由 index.js

5 修改global.css

/* 全局样式 */

    }
    .ql-editor{
        min-height: 300px;

    // axios请求拦截
    axios.interceptors.request.use(config => {
        // 为请求头对象，添加 Token 验证的 Authorization 字段
        config.headers.Authorization = window.sessionStorage.getItem('token')
        return config
    })
    Vue.prototype.$http = axios
    
    
    Vue.config.productionTip = false
    // 注册 TreeTable 组件
    Vue.component('tree-table', TreeTable)
    // 注册 富文本编辑器 组件为全局可用组件
    Vue.use(VueQuillEditor)
    // 添加时间过滤器
