使用elementuiadmin去掉默认mock权限控制的设置
elementuiadmin去掉默认mock权限控制的设置
一般前后端分离的项目,前端都很少通过mock模拟数据来调用测试,因为后期api出来后,可能还得修改结构,颇为麻烦。
本文从实践中总结,完全去掉默认的mock控制。
1.找到vue.config.js文件,去掉mock的加载
devServer: {
port: port,
open: true,
overlay: {
warnings: false,
errors: true
}
// before: require('./mock/mock-server.js') // 注释掉这一行
}
2.找到main.js,注释掉相关mock
// if (process.env.NODE_ENV === 'production') {
// const { mockXHR } = require('../mock')
// mockXHR()
// }
3.login.vue登录页面,直接调用api/user.js下的方法。
先引用login和reg进来,否则用默认的登录接口会再调用用户详情接口
import { login, reg } from '@/api/user'
把原来的登录方法注释掉,直接调用成功后,把登录token值set到js-cookie里
handleLogin() {
this.$refs.loginForm.validate(valid => {
if (valid) {
this.loading = true
login(this.loginForm).then((res) => {
if (res && res.code === 0 && res.data && res.data.token) {
setToken(res.data.token)
this.$router.push({ path: this.redirect || '/', query: this.otherQuery })
this.loading = false
}
}).catch(() => {
this.loading = false
})
// this.$store.dispatch('user/login', this.loginForm)
// .then(() => {
// this.$router.push({ path: this.redirect || '/', query: this.otherQuery })
// this.loading = false
// })
// .catch(() => {
// this.loading = false
// })
} else {
console.log('error submit!!')
return false
}
})
},
4.登录后就是菜单的展示问题了,找到/layout/components/Sidebar/index.vue文件,去掉权限控制permission_routes参数,改为:
<sidebar-item v-for="route in getRouterList" :key="route.path" :item="route" :base-path="route.path" />
import routesArr from '@/router/index'
export default {
components: { SidebarItem, Logo, routesArr },
computed: {
getRouterList() {
return routesArr.options.routes
},
...mapGetters([
// 'permission_routes', // 注释掉
'sidebar'
]),
OK!完美!
vue-elementui-admin的动态权限控制
最近打算仔细的学习一下vue-elemnetui-admin的代码,一是工作需要用到,需要加工一些东西,还有一个就是打算之后好好学习vue,看看源码啥的,所以先从这个框架学起来。
都是一些自己的学习笔记,做一些记录,有不对的地方恳请大家指出,可以一起讨论。
学习了一下permission文件夹下的role.js,用来控制不同用户能够查看菜单的权限
