一、前提

我们使用的是require.context方法导入,在vite创建的项目内使用会报错"require not found",所以必须用webpack创建项目。或者有大能可以说说vite怎么解决这个问题。
2021年5月17日,经过几天测试,vite2的自动导入搞定了

二、规则

我们使用的规则是,搜索src/views/路径下的所有目录和子目录,搜索文件名叫做"index.vue"的文件,使用上级目录的名字作为组件名,进行注册。结构如下:
在这里插入图片描述
和公共组件注册一样,我们只注册index.vue组件,其他名称的组件不进行注册。

三、webpack项目导入

// src/router/index.ts

import {createRouter, createWebHashHistory, createWebHistory, RouteRecordRaw} from 'vue-router'
import store from "@/store";
import daxie from "@/util/upper";		// 引入一个方法,将字符串的首字母进行大写,我习惯将pathname首字母大写

// 路由自动化注册
const routerList:any = []
const requireComponent = require.context('@/views', true, /index.vue$/) // 找到views路径下的所有文件
const dynamic_route = requireComponent.keys().filter(fileName => {
    return true
})
// 现在文件数组是乱序的,我们首先进行排序,父级路由在前面,如果是子级路由在前面,结果父级理由还没有创建,就会报错
// console.log(dynamic_route,"排序前")
dynamic_route.sort(function (a,b):number{
    const jieguoa:any = a.split("").filter((item:string)=>{
        return "/" == item
    })
    const jieguob:any = b.split("").filter((item:string)=>{
        return "/" == item
    })
    if(jieguoa.length<jieguob.length){return -1}
    if(jieguoa.length>jieguob.length){return 1}
    return 0
})

// console.log(dynamic_route,"排序后")


dynamic_route.forEach(fileName => {
    const path = fileName.replace(".", "")
    const namelist = fileName.replace(".", "").replace("index.vue", "").split("/").filter((i:any) => {
        return i
    })
    // 测试配置
    const componentConfig = requireComponent(fileName)
    // 组件可以随意添加任何属性,目前添加一个canshu属性,是一个数组,里面存放着需要的动态参数
    // console.log(componentConfig.default,"组件配置2")
    // 每一层都需要手动指定,只做三层吧
    if(namelist.length == 1){
        routerList.push({
            path:"/"+ namelist[namelist.length - 1],
            name: daxie(namelist[namelist.length-1]),
            component:()=>import(`../views${path}`),
            children:[],
        })
    }else if(namelist.length == 2){
        routerList.forEach((item:any)=>{
            if(item.name == daxie(namelist[0])){
                // 判断组件是否需要参数
                const canshu = componentConfig.default.canshu || []
                if(canshu){
                    for (let i=0;i<canshu.length;i++){
                        canshu[i] = "/:"+canshu[i]
                    }
                    item.children.push({
                        path: namelist[namelist.length-1] + canshu.join(""),
                        name: daxie(namelist[namelist.length-1]),
                        component:()=>import(`../views${path}`),
                        children:[],
                    })
                }else{
                    item.children.push({
                        path: namelist[namelist.length-1],
                        name: daxie(namelist[namelist.length-1]),
                        component:()=>import(`../views${path}`),
                        children:[],
                    })
                }
            }
        })
    }else if(namelist.length == 3){
        routerList.forEach((item:any)=>{
            if(item.name == daxie(namelist[0])){
                item.children.forEach((yuansu:any)=>{
                    if(yuansu.name == daxie(namelist[1])){
                        // 判断是不是需要参数
                        const canshu = componentConfig.default.canshu || []
                        if(canshu){
                            for (let i=0;i<canshu.length;i++){
                                canshu[i] = "/:"+canshu[i]
                            }
                            yuansu.children.push({
                                path: namelist[namelist.length - 1]+canshu.join(""),
                                name: daxie(namelist[namelist.length-1]),
                                component:()=>import(`../views${path}`),
                            })
                        }else {
                            yuansu.children.push({
                                path: namelist[namelist.length - 1],
                                name: daxie(namelist[namelist.length-1]),
                                component:()=>import(`../views${path}`),
                            })
                        }
                    }
                })
            }
        })
    }
})
const routes: Array<RouteRecordRaw> = [
    {
        path: '/',
        name: 'Home',
        component: ()=>import("@/views/shouye/shouye.vue")
    },
    {
        path: '/about',
        name: 'About',
        component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
    },
    ...routerList,
    {
        path: '/404',
        name: '404',
        component: () => import('@/views/404.vue')
    },
    {
        path: '/:pathMatch(.*)',
        redirect: '/404'
    },
]
// 注意顺序,根据最新的路由匹配规则,404页面必须在最后,
console.log(routes,"查看路由表内容")

const router = createRouter({
    history: createWebHistory(),
    // history: createWebHashHistory(),
    routes
})

export default router

这样,只需要根据规则创建组件,就会被自动注册到路由里面。免去手动注册的繁琐操作。

四、vite2项目导入

import {createRouter, createWebHashHistory, createWebHistory, Router, RouteRecordRaw} from 'vue-router'
import daxie from "@/util/upper"
import {isMainThread} from "worker_threads";
// 路由自动化注册
const routerList:any = []
// 第一层的都是特殊用途的组件,例如404.vue等,手动输入到router里面了
// 第二层
const modulesFiles1:any = import.meta.globEager('../views/*/index.vue')
const modulesname1  = Object.keys(modulesFiles1).filter((item:any)=>true)
modulesname1.forEach((item:string)=>{
    const name = item.split("/")[2]
    const canshu = modulesFiles1[item].default.canshu || ""
    // 如果有参数
    if(canshu){
        let casnhulist = ""
        canshu.forEach((item:string)=>{
            casnhulist = casnhulist + "/:" + item
        })
        routerList.push({
            name:daxie(name),
            path:"/" + name + canshu,
            component:()=>import(`../views/${name}/index.vue`),
            children:[],
        })
    }else {
        // 如果没有参数
        routerList.push({
            name: daxie(name),
            path: "/" + name,
            component: () => import(`../views/${name}/index.vue`),
            children: [],
        })
    }
})
// 第三层
const modulesFiles2:any = import.meta.globEager('../views/*/*/index.vue')
const modulesname2  = Object.keys(modulesFiles2).filter((item:any)=>true)
modulesname2.forEach((item:string)=>{
    const namelist = item.split("/")
    const name = namelist[3]
    const parentname = namelist[2]
    const canshu = modulesFiles2[item].default.canshu || ""
    routerList.forEach((item:any)=>{
        if(item.name == daxie(parentname)){
            // 如果有参数
            if(canshu){
                let casnhulist = ""
                canshu.forEach((item:string)=>{
                    casnhulist = casnhulist + "/:" + item
                })
                item.children.push({
                    name:daxie(name),
                    path:"/" + name + casnhulist,
                    component:()=>import(`../views/${parentname}/${name}/index.vue`),
                    children:[],
                })
            }else{
                // 没有参数
                item.children.push({
                    name:daxie(name),
                    path:"/" + name,
                    component:()=>import(`../views/${parentname}/${name}/index.vue`),
                    children:[],
                })
            }
        }
    })
})
// 如果有第四层,就再加一个,真是又臭又长啊
console.log(routerList,"kankan")
const routes: Array<RouteRecordRaw> = [
    {
        path:"/",
        redirect:"/login",
    },
    ...routerList,
    {
        path: '/404',
        name: '404',
        component: () => import('@/views/404.vue')
    },
    {
        path: '/:pathMatch(.*)',
        redirect: '/404'
    },
]

console.log(routes,"路由表")

const router = createRouter({
    history: createWebHistory(),
    // history: createWebHashHistory(),
    routes
})
// 在VUE中路由遇到Error: Avoided redundant navigation to current location:报错显示是路由重复
const originalPush = router.push
router.push = function push(location) {
    return originalPush.call(this, location).catch(err => err)
}

export default router
