消息函数：
- 定义了
msgSuccess、msgError、msgWarning和msgInfo方法，用于显示不同类型的消息。日期格式化：
_parseTime函数根据给定的模式格式化日期，支持多种输入类型。排序：
_sortBy函数允许根据指定字段对对象数组进行升序或降序排序。数字格式化：
_formatNumber方法格式化数字，添加千分位分隔符。随机数生成：
_mathRandom1000函数生成一个介于 0 到 999 之间的随机整数。移动设备检测：
_isMobile方法根据用户代理字符串检查用户是否在移动设备上。
示例用法
可以提供一个安装和使用该插件的示例，以帮助用户理解如何在 Vue 应用中使用它。以下是简单的示例：
import Vue from 'vue';
import MyPlugin from './path/to/my-plugin';Vue.use(MyPlugin);// 现在你可以在组件中使用这些方法
this.msgSuccess('操作成功！');
