简单回顾vue
首先强调：
修改源：
npm config set registry https://registry.npm.taobao.org
创建脚手架：
vue init webpack Vue项目名称
#记得把route的这个设置为yes,其他的设置为no 比如: Install vue-router? Yes
插件：
axios，发送Ajax请求
vuex，保存所有组件共用的变量
vue-cookies，操作cookie
流程详细
1、创建脚手架
#可以用淘宝源来下载，这样下载的快
npm config set registry https://registry.npm.taobao.org
vue init webpack
#吧route的那一个设置为yes,其他的设置为no
2、运行
cd Vue项目名称
npm run dev
3、显示组件
# 用于点击查看组件
首页
# 组件显示的位置
4、路由配置
index.js
import Vue from 'vue'
import Router from 'vue-router'
import Index from '@/components/Index'
import Login from '@/components/Login'
import Course from '@/components/Course'
import Micro from '@/components/Micro'
import News from '@/components/News'
import CourseDetail from '@/components/CourseDetail'
import NotFound from '@/components/NotFound'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'index',
component: Index
},
{
path: '/index',
name: 'index',
component: Index
},
{
path: '/course',
name: 'course',
component: Course
},
{
path: '/course-detail/:id/',
name: 'courseDetail',
component: CourseDetail
},
{
path: '/micro',
name: 'micro',
component: Micro
},
{
path: '/news',
name: 'news',
component: News
},
{
path: '/login',
name: 'login',
component: Login
},
{
path: '*',
component: NotFound
}
],
mode: 'history'
})
# 定义路由
{
path: '/course-detail/:id/',
name: 'courseDetail',
component: CourseDetail
},
{
path: '/login',
name: 'login',
component: Login
},
{
path: '*',
component: NotFound
}
# router-link参数
{{item.name}}
首页
# 获取传过来的参数
this.$route.params.id
# 重定向
this.$router.push('/index')
注意
我们访问的时候url一般会带有‘#’,如果不想有，在路由后面加上 mode: 'history'
5、写组件
组件写在src/components下
登录页面
6、发送ajax请求：axios
#发送ajax请求需要安装axios组件
npm install axios
npm install axios
main.js
import Vue from 'vue'
import App from './App'
import router from './router'
import axios from 'axios'
Vue.prototype.$axios = axios
Vue.config.productionTip = false
...
组件使用：
this.$axios.request({
url: 'http://127.0.0.1:8000/login/',
method: 'POST',
data: {
username: this.username,
password: this.password
},
responseType: 'json'
}).then(function (response) {
console.log(response.data)
that.$router.push('/index')
})
PS：重定向 that.$router.push('/index')
7、vuex：保存所有组件共用的变量
安装
npm install vuex
具体步骤：
a、先创建一个文件夹，store----store.js
b、要先使用就先导入
c、实例化一个对象，并且让别人可以用
d、这样每一个组件都可以用username和token了
npm install vuex
main.js
import Vue from 'vue'
import App from './App'
import router from './router'
import axios from 'axios'
import store from './store/store' # vuex
Vue.prototype.$axios = axios
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
store, # vuex
router,
components: { App },
template: '8、vue-cookies：操作cookie
npm install vue-cookies
npm install vue-cookies
Cookie.get('username')
Cookie.set('username', data.username, '20min')
Cookie.remove('username')
src/store/store.js
import Vue from 'vue'
import Vuex from 'vuex'
import Cookie from 'vue-cookies' # vue-cookies
Vue.use(Vuex)
export default new Vuex.Store({
// 组件中通过 this.$store.state.username 调用
state: {
username: Cookie.get('username'), # vue-cookies
token: Cookie.get('token') # vue-cookies
},
mutations: {
// 组件中通过 this.$store.commit(参数) 调用
saveToken: function (state, data) {
state.username = data.username
state.token = data.token
Cookie.set('username', data.username, '20min') # vue-cookies
Cookie.set('token', data.token, '20min')
},
clearToken: function (state) {
state.username = null
state.token = null
Cookie.remove('username') # vue-cookies
Cookie.remove('token')
}
}
})
三、代码实现
前端代码
index.html
s6vue
index.html
main.js
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import store from './store/store' //
import axios from 'axios' // 要是用axios，就得先导入
Vue.prototype.$axios = axios //注册，以后就可以用$axios来定义了
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
store,
router,
components: { App },
template: 'app.vue
router -- index.js
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Index from '@/components/Index'
import Login from '@/components/Login'
import Micro from '@/components/Micro'
import News from '@/components/News'
import Course from '@/components/Course'
import CourseDetail from '@/components/CourseDetail'
import NotFound from '@/components/NotFound'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'HelloWorld',
component: HelloWorld
},
{
path: '/index',
name: 'index',
component: Index
},
{
path: '/login',
name: 'Login',
component: Login
},
{
path: '/course',
name: 'Course',
component: Course
},
{
path: '/course-detail/:id/',
name: 'CourseDetail',
component: CourseDetail
},
{
path: '/micro/',
name: 'Micro',
component: Micro
},
{
path: '/course-detail/:id/',
name: 'CourseDetail',
component: CourseDetail
},
{
path: '/news/',
name: 'News',
component: News
},
{
path: '*',
component: NotFound
}
],
mode:'history'
})
router ---index.js
组件components
Index.vue
{{ msg }}
Index.vue
Login.vue
登录页面
用户名：

保存全局使用的变量store
store.js
import Vue from 'vue'
import Vuex from 'vuex'
import Cookie from 'vue-cookies'
Vue.use(Vuex)
export default new Vuex.Store({
//组件中通过this.$store.state.username 调用
state:{
username:Cookie.get('username'),
token:Cookie.get('token')
},
mutations:{
//组件中通过this.$store.commit(参数)调用
saveToken:function (state,data) { //存放用户名和token的函数
state.username = data.username //data代指从后端返回过来的数据
state.token = data.token
Cookie.set('username',data.username,'20min') //吧用户名和token存放到cookie中
Cookie.set('token',data.token,'20min')
},
//清空token和cookie
clearToken:function (state) {
state.username=null
state.token= null
Cookie.remove('username')
Cookie.remove('token')
}
}
})
store.js
后台代码
urls.py
"""day145vue和restful配合 URL Configuration
