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
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:
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。
// 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$/) // 找到views路径下的所有文件
const dynamic_route = requireComponent.keys().filter(fileName => {
return true
})
// 现在文件数组是乱序的,我们首先进行排序,父级路由在前面,如果是子级路由在前面,结果父级理由还没有创建,就会报错
// console.log(dynamic_route,"排序前")
dynamic_route.sort(function (a,b):number{
const jieguoa:any = a.split("").filter((item:string)=>{
return "/" == item
})
const jieguob:any = b.split("").filter((item:string)=>{
return "/" == item
})
if(jieguoa.lengthjieguob.length){return 1}
return 0
})
// console.log(dynamic_route,"排序后")
dynamic_route.forEach(fileName => {
const path = fileName.replace(".", "")
const namelist = fileName.replace(".", "").replace("index.vue", "").split("/").filter((i:any) => {
return i
})
// 测试配置
const componentConfig = requireComponent(fileName)
// 组件可以随意添加任何属性,目前添加一个canshu属性,是一个数组,里面存放着需要的动态参数
// console.log(componentConfig.default,"组件配置2")
// 每一层都需要手动指定,只做三层吧
if(namelist.length == 1){
routerList.push({
path:"/"+ namelist[namelist.length - 1],
name: daxie(namelist[namelist.length-1]),
component:()=>import(`../views${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;iimport(`../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;iimport(`../views${path}`),
})
}else {
yuansu.children.push({
path: namelist[namelist.length - 1],
name: daxie(namelist[namelist.length-1]),
component:()=>import(`../views${path}`),
})
}
}
})
}
})
}
})
const routes: Array = [
{
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。
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
