Vue.use(VueResource) 3、在webpack.dev.conf配置express并设置路由规则 #webpack.dev.conf.js
// 首先在const portfinder require(portfinder)后添加// nodejs开发框架express用来简化操作
const express require(express)
// 创建node.js的express开发框架的实例
const app express()
// 引用的json地址
var appData require(../data.json)
// json某一个key
var goods appData.resultvar apiRoutes express.Router()
app.use(/api, apiRoutes) 1get请求配置 #webpack.dev.conf.js
// 在devServer选项中添加以下内容
before(app) {app.get(/api/someApi, (req, res) {res.json({// 这里是你的json内容})})
} 注意 修改配置文件完毕后需要重新运行命令npm run dev即可。 2post请求配置。如果要配置post请求需要在该文件夹配置如下 #webpack.dev.conf.js
apiRoutes.post(/foods, function (req, res) { //注意这里改为post就可以了res.json({error: 0,data: foods});
})
// 在组件里面
#...vue
created () {this.$http.post(http://localhost:8080/api/foods).then((res) {console.log(res)})
} 3完整配置 use strict
const utils require(./utils)
const webpack require(webpack)
const config require(../config)
const merge require(webpack-merge)
const path require(path)
const baseWebpackConfig require(./webpack.base.conf)
const CopyWebpackPlugin require(copy-webpack-plugin)
const HtmlWebpackPlugin require(html-webpack-plugin)
const FriendlyErrorsPlugin require(friendly-errors-webpack-plugin)
const portfinder require(portfinder)const HOST process.env.HOST
const PORT process.env.PORT Number(process.env.PORT)//增加express --start
const express require(express)
const app express()
var appData require(../goods.json)
var goods appData.goods
var apiRoutes express.Router()
app.use(/api, apiRoutes)
//增加express --endconst devWebpackConfig merge(baseWebpackConfig, {module: {rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap, usePostCSS: true })},// cheap-module-eval-source-map is faster for developmentdevtool: config.dev.devtool,// these devServer options should be customized in /config/index.jsdevServer: {clientLogLevel: warning,historyApiFallback: {rewrites: [{ from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, index.html) },],},hot: true,contentBase: false, // since we use CopyWebpackPlugin.compress: true,host: HOST || config.dev.host,port: 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 FriendlyErrorsPluginwatchOptions: {poll: config.dev.poll,},//增加express --startbefore(app) {app.get(/api/goods, (req, res) {res.json({code: 0,data: goods})})}//增加express --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-pluginnew HtmlWebpackPlugin({filename: index.html,template: index.html,inject: true}),// copy custom static assetsnew CopyWebpackPlugin([{from: path.resolve(__dirname, ../static),to: config.dev.assetsSubDirectory,ignore: [.*]}])]
})module.exports new Promise((resolve, reject) {portfinder.basePort process.env.PORT || config.dev.portportfinder.getPort((err, port) {if (err) {reject(err)} else {// publish the new Port, necessary for e2e testsprocess.env.PORT port// add port to devServer configdevWebpackConfig.devServer.port port// Add FriendlyErrorsPlugindevWebpackConfig.plugins.push(new FriendlyErrorsPlugin({compilationSuccessInfo: {messages: [Your application is running here: http://${devWebpackConfig.devServer.host}:${port}],},onErrors: config.dev.notifyOnErrors? utils.createNotifierCallback(): undefined}))resolve(devWebpackConfig)}})
}) 4、检测 npm run dev 后在浏览器地址栏中输入http://localhost:8080/api/goods即可看到数据 注意新建goods.json引入时候的路径 在使用中有个粗心的位置就是npm run dev的时候总是报错missing scripts dev导致项目启动不了。 考虑到可能是package.json文件里的scripts里面没有dev导致所以查看结果却有 最后就是粗心导致的问题原来我是在 cd vueCli 这个目录下去 npm run dev 的所以肯定会missing scripts dev改成cd exprice目录下去 npm run dev 就行了。所以一定得细心啊。 转载于:https://www.cnblogs.com/goloving/p/8695346.html
