Laravel + Vue 开发单页应用

开发环境:
Homestead + Laravel5.3 + vue2 + vue-resource1 + vue-router2 + vuex2

源码放在 github 上面,源码地址

环境安装就不做介绍了,由于 5.3 自带 vue2 和 vue-resource,但是需要安装 vue-route 和 vuex
在 package.json 中添加

“vue-router”: “^2.0.1”,

}
执行 npm install 安装

介绍下开发的需求,主要有三个页面:

  1. 首页展示推荐新闻
  2. 新闻列表
  3. 新闻详情

import Vue from ‘vue’;
import VueResource from ‘vue-resource’;
Vue.use(VueResource);
import VueRouter from ‘vue-router’;
Vue.use(VueRouter);
import store from ‘./store/’; // vuex 数据存储所需对象
import routes from ‘routes’; // 路由配置文件
// 实例化路由
const router = new VueRouter({
routes
});
// 实例化 Vue
var vm = new Vue({
store,
router
}).$mount(‘#app’);

数据vuex

vuex 我们使用多模块的开发模式,这在项目中设计十分有必要的,如果把所有的数据一个实例上面,管理显得还是十分的混乱。

import Vue from ‘vue’;
import Vuex from ‘vuex’;
import news from ‘./news’;
Vue.use(Vuex);
export default new Vuex.Store({
// 可以设置多个模块
modules: {
news
}
});

书写 news 模块代码
resources/asserts/store/news.js

import api from ‘../api’; // 主要是异步调用接口文件,下面有介绍
export default{
state: {
recommend: [], // 存储推荐列表
lists: [], // 存储列表
detail: {} // 存储详情
},
mutations: {
// 注意,这里可以设置 state 属性,但是不能异步调用,异步操作写到 actions 中
SETRECOMMEND(state, recommend) {
state.recommend = recommend;
},
SETLISTS(state, lists) {
state.lists = lists;
},
SETDETAIL(state, detail) {
state.detail = detail;
}
},
actions: {
GETDETAIL({commit}, id) {
// 获取详情,并调用 mutations 设置 detail
api.getNewsDetail(id).then(function(res) {
commit(‘SETDETAIL’, res.data);
document.body.scrollTop = 0;
});
},
GETRECOMMEND({commit}) {
// 获取推荐,并调用 mutations 设置 recommend
api.getNewsRecommend().then(function(res) {
commit(‘SETRECOMMEND’, res.data);
});
},
GETLISTS({commit}) {
// 获取列表,并调用 mutations 设置 lists
api.getNewsLists().then(function(res) {
commit(‘SETLISTS’, res.data);
});
}
}
};

看到上面的代码中引入了 api ,我将接口的请求全部放到 api.js 中,便于管理,其实这里也可以分成模块。

import Vue from ‘vue’;

Vue.use(VueResource);
// 设置 Laravel 的 csrfToken
Vue.http.interceptors.push((request, next) => {
request.headers.set(‘X-CSRF-TOKEN’, Laravel.csrfToken);
next();
});
const API_ROOT = ; // 可以根据自己的开发环境设置
export default({
// 首页推荐信息
getNewsRecommend: function() {
return Vue.resource(API_ROOT + ‘/news’).get();
},
// 列表信息
getNewsLists: function() {
return Vue.resource(API_ROOT + ‘/newslist’).get();

getNewsDetail: function(id) {

});

服务端 API

服务端的 api 只是一个数据的模拟,没有做深入的开发

return [

‘title’ => ‘news’,
‘content’ => ‘content’,
‘created_at’ => date(‘Y-m-d H:i:s’)
];
});

运行

2
php artisan serve // 开启 web
gulp // 打包前端资源,开发的时候用 gulp watch 监听实时浏览

打开浏览器,访问 http://localhost:8000 查看效果。

这个例子只是简单的使用了 Laravel 和 vue,详细开发请查看官方文档。
