  • Vue+restfulframework示例

     一、简单回顾vue

    前不久我们已经了解了vue前端框架,所以现在强调几点：

    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

    二、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
<router-link to="/index">首页</router-link>
                
# 组件显示的位置
<router-view/>

    4、写路由

     1 import Vue from 'vue'
 2 import Router from 'vue-router'
 3 import Index from '@/components/Index'
 4 import Login from '@/components/Login'
 5 import Course from '@/components/Course'
 6 import Micro from '@/components/Micro'
 7 import News from '@/components/News'
 8 import CourseDetail from '@/components/CourseDetail'
 9 import NotFound from '@/components/NotFound'
10 
11 Vue.use(Router)
12 
13 export default new Router({
14   routes: [
15     {
16       path: '/',
17       name: 'index',
18       component: Index
19     },
20     {
21       path: '/index',
22       name: 'index',
23       component: Index
24     },
25     {
26       path: '/course',
27       name: 'course',
28       component: Course
29     },
30     {
31       path: '/course-detail/:id/',
32       name: 'courseDetail',
33       component: CourseDetail
34     },
35     {
36       path: '/micro',
37       name: 'micro',
38       component: Micro
39     },
40     {
41       path: '/news',
42       name: 'news',
43       component: News
44     },
45     {
46       path: '/login',
47       name: 'login',
48       component: Login
49     },
50     {
51       path: '*',
52       component: NotFound
53     }
54   ],
55   mode: 'history'
56 })
    View Code
     1 # 定义路由
 2                     {
 3                       path: '/course-detail/:id/',
 4                       name: 'courseDetail',
 5                       component: CourseDetail
 6                     },
 7                     {
 8                       path: '/login',
 9                       name: 'login',
10                       component: Login
11                     },
12                     {
13                       path: '*',
14                       component: NotFound
15                     }
16                 
17                 
18                 # router-link参数
19                     <router-link :to="{'path':'/course-detail/'+item.id }">{{item.name}}</router-link>
20                     <router-link to="/index">首页</router-link>
21     
22                 # 获取传过来的参数
23                     this.$route.params.id
24                 # 重定向
25                     this.$router.push('/index')
26
    View Code

    注意：

    如果不想在url显示#，可以在路由里面加上这样一个参数

      mode: 'history'

    5、写组件

     1 <template>
 2 
 3   <div>
 4     <h1>登录页面</h1>
 5     <div>
 6       <input type="text" v-model="username" placeholder="用户名">
 7       <input type="text" v-model="password" placeholder="密码">
 8       <a @click="doLogin">提交</a>
 9     </div>
10   </div>
11 </template>
12 
13 <script>
14 
15 export default {
16   # 定义局部字段
17   data () {
18     return {
19       username: '',
20       password: ''
21     }
22   },
23   # 加载时执行
24   mounted:function(){
25   },
26   # 定义局部方法
27   methods:{
28     doLogin() {
29       var that = this
30       this.$axios.request({
31         url: 'http://127.0.0.1:8000/login/',
32         method: 'POST',
33         data: {
34           username: this.username,
35           password: this.password
36         },
37         responseType: 'json'
38       }).then(function (response) {
39         console.log(response.data)
40         // 找到全局变量，把用户名和token赋值到其中。
41         that.$store.commit('saveToken',response.data)
42         // 重定向到index
43         that.$router.push('/index')
44       })
45     }
46   }
47 }
48 </script>
49 
50 <!-- Add "scoped" attribute to limit CSS to this component only -->
51 <style scoped>
52 
53 </style>
    View Code

    6、发送ajax请求：axios

    #发送ajax请求需要安装axios组件
npm install axios
     1 npm install axios
 2 
 3 main.js 
 4     import Vue from 'vue'
 5     import App from './App'
 6     import router from './router'
 7     
 8     import axios from 'axios'
 9     
10     Vue.prototype.$axios = axios
11 
12     Vue.config.productionTip = false
13     ...
14 
15 组件使用：
16     this.$axios.request({
17     url: 'http://127.0.0.1:8000/login/',
18     method: 'POST',
19     data: {
20       username: this.username,
21       password: this.password
22     },
23     responseType: 'json'
24   }).then(function (response) {
25     console.log(response.data)
26     
27     that.$router.push('/index')
28   })
29 
30 PS：重定向 that.$router.push('/index')
    View Code

    7、vuex：保存所有组件共用的变量

    安装  
npm install vuex

     如果想用vuex需要做这么几件事：

    • 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
     1 npm install vuex 
 2 
 3 main.js 
 4 import Vue from 'vue'
 5 import App from './App'
 6 import router from './router'
 7 import axios from 'axios'
 8 
 9 import store from './store/store'    # vuex
10 
11 Vue.prototype.$axios = axios
12 
13 Vue.config.productionTip = false
14 
15 /* eslint-disable no-new */
16 new Vue({
17   el: '#app',
18   store,                            # vuex
19   router,
20   components: { App },
21   template: '<App/>'
22 })
23 
24 src/store/store.js
25 import Vue from 'vue'
26 import Vuex from 'vuex'
27 import Cookie from 'vue-cookies'
28 
29 Vue.use(Vuex)
30 
31 export default new Vuex.Store({
32   // 组件中通过 this.$store.state.username 调用
33   state: {
34     username: Cookie.get('username'),
35     token: Cookie.get('token')
36   },
37   mutations: {
38     // 组件中通过 this.$store.commit(参数)  调用
39     saveToken: function (state, data) {
40       state.username = data.username
41       state.token = data.token
42       Cookie.set('username', data.username, '20min')
43       Cookie.set('token', data.token, '20min')
44 
45     },
46     clearToken: function (state) {
47       state.username = null
48       state.token = null
49       Cookie.remove('username')
50       Cookie.remove('token')
51     }
52   }
53 })
    View Code

    8、vue-cookies：操作cookie

    安装
npm install vue-cookies
     1 npm install vue-cookies 
 2 
 3 
 4 Cookie.get('username')
 5 
 6 Cookie.set('username', data.username, '20min')
 7 Cookie.remove('username')
 8 
 9 
10 src/store/store.js
11 import Vue from 'vue'
12 import Vuex from 'vuex'
13 import Cookie from 'vue-cookies'    # vue-cookies
14 
15 Vue.use(Vuex)
16 
17 export default new Vuex.Store({
18   // 组件中通过 this.$store.state.username 调用
19   state: {
20     username: Cookie.get('username'),    # vue-cookies
21     token: Cookie.get('token')            # vue-cookies
22   },
23   mutations: {
24     // 组件中通过 this.$store.commit(参数)  调用
25     saveToken: function (state, data) {
26       state.username = data.username
27       state.token = data.token
28       Cookie.set('username', data.username, '20min')    # vue-cookies
29       Cookie.set('token', data.token, '20min')    
30 
31     },
32     clearToken: function (state) {
33       state.username = null
34       state.token = null
35       Cookie.remove('username')    # vue-cookies
36       Cookie.remove('token')
37     }
38   }
39 })
    View Code

    三、代码实现

     前端代码：

15 </html>
    index.html
     1 // The Vue build version to load with the `import` command
 2 // (runtime-only or standalone) has been set in webpack.base.conf with an alias.
 3 import Vue from 'vue'
 4 import App from './App'
 5 import router from './router'
 6 import store from './store/store'  //
 7 import axios from 'axios'    // 要是用axios，就得先导入
 8 Vue.prototype.$axios = axios  //注册，以后就可以用$axios来定义了
 9 
10 Vue.config.productionTip = false
11 
12 /* eslint-disable no-new */
13 new Vue({
14   el: '#app',
15   store,
16   router,
17   components: { App },
18   template: '<App/>'
19 })
    main.js
