element ui 中 使用v-loading 的加载效果
背景图如下 自取：
产生报错的原因可能如下
1 css预处理使用的是sass，可能没有安装
2 svg图标在vue中的使用，可能没有安装
3 去除空格的工具函数文章来源：https://www.toymoban.com/news/detail-508079.html
src\utils\validate.js文章来源地址https://www.toymoban.com/news/detail-508079.html
export function validUsername(str) {
const valid_map = ['admin', 'editor']
return valid_map.indexOf(str.trim()) >= 0
