taro3.x: tarojs-router

npm install tarojs-router

简单实现：

github: https://github.com/lblblong/tarojs-router

创建router配置目录src/router

src/router/middleware/author-check.ts

import storage from '@/utils/storage'
import Taro from '@tarojs/taro'
import { IMiddlware } from "tarojs-router"
import { toLogin } from '../router'


export const AuthCheck: IMiddlware<{ mustLogin: boolean }> = async (ctx, next) => {
  if (ctx.route.ext?.mustLogin) {
    const token = storage.getItem('token')
    if (!token) {
      const { confirm } = await Taro.showModal({
        title: '提示',
        content: '请先登录'
      })

      if (confirm) {
        toLogin()
      }
      throw Error('该页面必须要登陆：' + ctx.route.url)
    }
  }

  await next()
}

src/router/index.ts

import { Router } from 'tarojs-router'
import { AuthCheck } from './middleware/author-check'

export * from './router'

Router.config({
  middlewares: [AuthCheck]

    if (IS_H5) {
        url = `/login/phone/index`
    } else {
        url = `/login/index`
    }
    if (type) {
        Router.navigate(

            }
        )
    } else {
        Router.navigate(
            { url },
            { type: NavigateType.redirectTo }

export const navigateHouseModule = (module: string, params: any = {}, data: any = {}) => {

        beforeRouteEnter: [HasLoginBack],

        ext: {

            checkLogin: true,

            type: 'navigateTo'

        }

    }

}

 src/middleware/auth-check.ts -> hasLoginback:

import storage from '@/utils/storage'
import { toUrlParam } from '@/utils/urlHandler'
import { IMiddlware } from "tarojs-router"
import { toLogin } from '../router'

interface ILoginBack {
  checkLogin: boolean

      const backUrl = `${ctx.route.url}${toUrlParam(ctx.params)}`
      toLogin({ backUrl: encodeURIComponent(backUrl), isTab }, ctx.route.ext?.type)

　　　　throw Error('该页面必须要登陆：' + ctx.route.url) // 不加h5会继续跳转

} } await next() }
