新建一个auth.js
/**
* @description 权限存储函数
*/
const authorizationKey = 'Authorization'
export function getAuthorization() {
return uni.getStorageSync(authorizationKey)
}
export function setAuthorization(authorization) {
return uni.setStorageSync(authorizationKey, authorization)
}
export function removeAuthorization(authorization) {
return uni.removeStorageSync(authorizationKey)
}
新建route.js
import { getAuthorization } from '@/utils/auth.js'
// 白名单
const whiteList = [
'/', // 注意入口页必须直接写 '/'
'/pages/Login/Login'
]
export default async function() {
const list = ['navigateTo', 'redirectTo', 'reLaunch', 'switchTab']
// 用遍历的方式分别为,uni.navigateTo,uni.redirectTo,uni.reLaunch,uni.switchTab这4个路由方法添加拦截器
list.forEach(item => {
uni.addInterceptor(item, {
invoke(e) {
// 获取要跳转的页面路径（url去掉"?"和"?"后的参数）
const url = e.url.split('?')[0]
console.log('url', url)
// 判断当前窗口是白名单，如果是则不重定向路由
let pass
if (whiteList) {
pass = whiteList.some((item) => {
if (typeof (item) === 'object' && item.pattern) {
return item.pattern.test(url)
}
return url === item
})
}
// 不是白名单并且没有token
if (!pass && !getAuthorization()) {
uni.showToast({
title: '请先登录',
icon: 'none'
})
uni.navigateTo({
url: "/pages/Login/Login"
})
return false
}
return e
},
fail(err) { // 失败回调拦截
console.log(err)
}
})
})
}
APP.vue
import routingIntercept from '@/router/route.js'
export default {
onLaunch: function() {
console.log('App Launch');
// 对路由进行统一拦截，实现路由导航守卫 router.beforeEach 功能
routingIntercept()
},
onShow: function() {
console.log('App Show')
},
onHide: function() {
console.log('App Hide')
}
}
