/**
|
||
* 路由全局前置守卫模块
|
||
*
|
||
* 提供完整的路由导航守卫功能
|
||
*
|
||
* ## 主要功能
|
||
*
|
||
* - 登录状态验证和重定向
|
||
* - 动态路由注册和权限控制
|
||
* - 菜单数据获取和处理(前端/后端模式)
|
||
* - 用户信息获取和缓存
|
||
* - 页面标题设置
|
||
* - 工作标签页管理
|
||
* - 进度条和加载动画控制
|
||
* - 静态路由识别和处理
|
||
* - 错误处理和异常跳转
|
||
*
|
||
* ## 使用场景
|
||
*
|
||
* - 路由跳转前的权限验证
|
||
* - 动态菜单加载和路由注册
|
||
* - 用户登录状态管理
|
||
* - 页面访问控制
|
||
* - 路由级别的加载状态管理
|
||
*
|
||
* ## 工作流程
|
||
*
|
||
* 1. 检查登录状态,未登录跳转到登录页
|
||
* 2. 首次访问时获取用户信息和菜单数据
|
||
* 3. 根据权限动态注册路由
|
||
* 4. 设置页面标题和工作标签页
|
||
* 5. 处理根路径重定向到首页
|
||
* 6. 未匹配路由跳转到 404 页面
