ps：這個(gè)簡(jiǎn)單小項(xiàng)目只提供一個(gè)小小小的骨架，需要向“它”身上具體加多少“肉”，需要大家考慮好功能和布局后進(jìn)行完善。

主頁(yè)分析：大體上分為上（header）、中（body或content）、下（footer）三部分，中間body部分是由若干個(gè)相同的li組成的“列表”，所以我們可將li定義為一個(gè)組件。

詳情頁(yè)分析：也分為上、中、下三部分。

在src文件夾（也就是我們碼農(nóng)主要工作區(qū)）下，創(chuàng)建assets文件夾（用來(lái)保存項(xiàng)目所需圖片）、components（存組件commonFooter.vue、DetailHeader.vue、homeHeader.vue、list.vue）、pages（存頁(yè)面goodsDetail.vue、home.vue）和main.js文件。詳情請(qǐng)看下圖：

ps: 1.具體文件夾以及文件名稱(chēng)可根據(jù)自己項(xiàng)目進(jìn)行“自擬”。 2.這里的每一個(gè)*.vue文件都是一個(gè)組件。

主頁(yè)商品信息及圖片， 是從服務(wù)器端返回的json數(shù)據(jù)，不可能所以商品都“寫(xiě)死”。故這里需要模擬后臺(tái)建立了一個(gè)數(shù)據(jù)文件。在根目錄下建立一個(gè)goods.json文件用來(lái)放“偽數(shù)據(jù)”，如下圖：

注意json里不能帶有注釋和其他文字,不然會(huì)項(xiàng)目跑不起來(lái),出錯(cuò)

使用node中的express,
安裝express和axios

在main.js里配置axios到原型鏈中
注意標(biāo)記的那兩行

import Vue from "vue"

import App from "./App"

import router from "./router"

import axios from "axios" //注意這行

Vue.prototype.$http = axios; //注意這行

Vue.config.productionTip = false

new Vue({

el: "#app",

router,

components: { App },

template: ""

})

在build>>webpack.dev.conf.js配置express并設(shè)置路由規(guī)則

如圖:

代碼如下:

"use strict"

const utils = require("./utils")

const webpack = require("webpack")

const config = require("../config")

const merge = require("webpack-merge")

const baseWebpackConfig = require("./webpack.base.conf")

const HtmlWebpackPlugin = require("html-webpack-plugin")

const FriendlyErrorsPlugin = require("friendly-errors-webpack-plugin")

const portfinder = require("portfinder")

/* datura_lj 增加express 20171126 */

const express = require("express")

const app = express()

var appData = require("../goods.json")/*加載本地?cái)?shù)據(jù)文件*/

var goods = appData.goods

var apiRoutes = express.Router()

app.use("/api", apiRoutes)

/* 增加express end */

const devWebpackConfig = merge(baseWebpackConfig, {

module: {

rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap, usePostCSS: true })

},

// cheap-module-eval-source-map is faster for development

devtool: config.dev.devtool,

// these devServer options should be customized in /config/index.js

devServer: {

clientLogLevel: "warning",

historyApiFallback: true,

hot: true,

compress: true,

host: process.env.HOST || config.dev.host,

port: process.env.PORT || config.dev.port,

open: config.dev.autoOpenBrowser,

overlay: config.dev.errorOverlay ? {

warnings: false,

errors: true,

} : false,

publicPath: config.dev.assetsPublicPath,

proxy: config.dev.proxyTable,

quiet: true, // necessary for FriendlyErrorsPlugin

watchOptions: {

poll: config.dev.poll,

},

/* datura_lj 增加express 20171126 */

before(app) {

app.get("/api/goods", (req, res) => {

res.json({

code: 0,

data: goods

})

})

}

/* datura_lj 增加路由規(guī)則 end */

},

plugins: [

new webpack.DefinePlugin({

"process.env": require("../config/dev.env")

}),

new webpack.HotModuleReplacementPlugin(),

new webpack.NamedModulesPlugin(), // HMR shows correct file names in console on update.

new webpack.NoEmitOnErrorsPlugin(),

// https://github.com/ampedandwired/html-webpack-plugin

new HtmlWebpackPlugin({

filename: "index.html",

template: "index.html",

inject: true

}),

]

})

module.exports = new Promise((resolve, reject) => {

portfinder.basePort = process.env.PORT || config.dev.port

portfinder.getPort((err, port) => {

if (err) {

reject(err)

} else {

// publish the new Port, necessary for e2e tests

process.env.PORT = port

// add port to devServer config

devWebpackConfig.devServer.port = port

// Add FriendlyErrorsPlugin

devWebpackConfig.plugins.push(new FriendlyErrorsPlugin({

compilationSuccessInfo: {

messages: [`Your application is running here: http://${config.dev.host}:${port}`],

},

onErrors: config.dev.notifyOnErrors

? utils.createNotifierCallback()

: undefined

}))

resolve(devWebpackConfig)

}

})

})

npm run dev 之后,測(cè)試是否該數(shù)據(jù)可用，在瀏覽器地址欄中輸入：http://localhost:8080/api/goods ，在瀏覽器中展示出如下圖數(shù)據(jù)，代碼數(shù)據(jù)數(shù)取成功：

配置config/index.js:解決跨域問(wèn)題

在proxTable對(duì)象里寫(xiě):

proxyTable: {

"/api": {

target: "http://127.0.0.1:8080/api",

changeOrigin: true,

pathRewrite: {

"^/api": "/"

//寫(xiě)"/api"就等于寫(xiě)"http://127.0.0.1:8080/api"

//到時(shí)候?qū)?/api/goods"就等于寫(xiě)"http://127.0.0.1:8080/api/goods"

}

}

}

原來(lái)參考教程有些地方需要修改:

home.vue里的獲取數(shù)據(jù)要改成這樣才對(duì):

2.修改list.vue里的價(jià)格顯示那行代碼

3.在home.vue里修改組件 : v-for="(item, index) in items" :key="index" 這樣就可以運(yùn)行了

期待擴(kuò)寫(xiě)功能:實(shí)現(xiàn)點(diǎn)擊商品列表的某一項(xiàng)(商品列表為請(qǐng)求數(shù)據(jù)循環(huán)輸出),傳參到詳情頁(yè),詳情頁(yè)根據(jù)傳過(guò)來(lái)的參數(shù)去請(qǐng)求數(shù)據(jù)回來(lái)填充到頁(yè)面.
