使用vue-ci配合wekpack創(chuàng)建目錄

• 使用命令行進入某個磁盤目錄如E:\VueStudy

• 輸入vue init webpack vue-router-demo創(chuàng)建目錄

• 進入vue-router-demo目錄輸入npm install安裝依賴

• 修改config目錄下index.js的dev端口為80

• 輸入npm run dev運行項目，打開http://localhost掂铐，看到Vue主頁logo即成功

• ctrl+c退出批處理狀態(tài)

-##### 在package.json的依賴文件罕拂，加入axios依賴

"dependencies": {
    "vue": "^2.5.2",
    "vue-router": "^3.0.1",
    "axios": "^0.18.0"
  }

• 在命令行輸入npm install安裝axios依賴（每次添加依賴都需輸入命令，否則依賴無效）

• main.js文件引入axios

import Vue from 'vue'
import App from './App'
import router from './router'
import axios from 'axios'

Vue.config.productionTip = false
Vue.prototype.$http = axios

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

• components目錄中創(chuàng)建一些vue組件全陨，如圖

• 配置路由爆班，router目錄的index.js文件

import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)

export default new Router({
    // 去除#的hash模式
    mode: "history",
    routes: [
        {
            //我的班課
            path: '/',
            name: 'Index',
            component: resolve => require(['../components/Index.vue'], resolve)
        },
        {
            //任務(wù)中心
            path: '/task',
            name: 'Task',
            component: resolve => require(['../components/Task.vue'], resolve)
        },
        {
            //庫管理
            path: '/lib',
            name: 'Lib',
            component: resolve => require(['../components/Lib.vue'], resolve)
        },
        {
            //個人中心
            path: '/ucenter',
            name: 'UCenter',
            component: resolve => require(['../components/UCenter.vue'], resolve)
        },
        {
            //新建班課
            path: '/new_course',
            name: 'NewCourse',
            component: resolve => require(['../components/NewCourse.vue'], resolve)
        },
        {
            //班課詳情
            path: '/course/:id',
            name: 'CourseDetail',
            component: resolve => require(['../components/CourseDetail.vue'], resolve)
        }
    ]
})

• 路由跳轉(zhuǎn)例子：

無參跳轉(zhuǎn)

<router-link to="/">
    <img src="./assets/logo.png" class="logo"/>
</router-link>
<router-link to="/task" class="nav-item">任務(wù)中心</router-link>

路徑傳參跳轉(zhuǎn)：

<router-link :to="'/course/' + course.courseId">
    <img :src="course.cover" />
</router-link>

js跳轉(zhuǎn)：

_this.$router.push('/');

• GET請求示例

var _this = this;
        this.$http.get('http://localhost:8080/api/courses').then(function(response) {
            _this.courses = response.data;
});

<script>
export default {
    name: 'CourseDetail',
    data() {
        return {
            id: this.$route.params.id,
            course: {}
        };
    },
    created() {
        var _this = this;
        this.$http.get('http://localhost:8080/api/course/' + this.id).then(function(response) {
            _this.course = response.data;
        });
    }
};
</script>

• POST請求示例

<script>
export default {
    name: 'NewCourse',
    data() {
        return {
            loginUserId: 1,
            course: {
                courseName: '',
                courseClass: '',
                cover: ''
            }
        };
    },
    methods: {
        addCourse: function(course) {
            var _this = this;
            this.$http({
                method: 'post',
                url: 'http://localhost:8080/api/course',
                data: {
                    userId: _this.loginUserId,
                    courseName: course.courseName,
                    courseClass: course.courseClass,
                    cover: course.cover,
                    finished: 0
                }
            }).then(function() {
                alert('新增班課成功');
                _this.$router.push('/');
            });
        }
    }
};
</script>

• DELETE請求示例

deleteCourse: function(courseId,index) {
            var _this = this;
            this.$http({
                method: 'delete',
                url: 'http://localhost:8080/api/course/' + courseId
            }).then(function() {
                alert('班課刪除成功');
                 _this.courses.splice(index,1);
            });
        }
