<span>Axios.defaults.baseURL = 'https://api.example.com';//配置你的接口请求地址 Axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;//配置token,看情况使用 Axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';//配置请求头信息。</span>
<br><span>vue 访问本地json文件的数据测试配置方法<br>第一步，准备json数据<br>json文件位置：src/data/data.json<br>第二步，配置webpack.dev.conf.js 文件<br>在webpack.dev.config.js 里面添加如下代码：<br></span>
// webpack.dev.conf.js // 通过express导入路由 const express = require('express') const app = express() var appData = require('../src/data/data.json') // json卖家数据 var seller = appData.seller // json商品数据 var goods = appData.goods // json评论数据 var ratings = appData.ratings // 编写路由 var apiRoutes = express.Router() // 所有通过接口相关的api都会通过api这个路由导向到具体的路由 app.use('/api', apiRoutes) //devServer下写入如下代码： before(app) { app.get('/api/seller', (req, res) => { res.json({ errno: 0, data: seller })//接口返回json数据，上面配置的数据seller就赋值给data请求后调用 }), app.get('/api/goods', (req, res) => { res.json({ errno: 0, data: goods }) }), app.get('/api/ratings', (req, res) => { res.json({ errno: 0, data: ratings }) }) }
按照如上配置就大功告成了，webpack.dev.config.js 完整代码如下：
'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') // webpack.dev.conf.js // 通过express导入路由 const express = require('express') const app = express() var appData = require('../src/data/data.json') // json卖家数据 var seller = appData.seller // json商品数据 var goods = appData.goods // json评论数据 var ratings = appData.ratings // 编写路由 var apiRoutes = express.Router() // 所有通过接口相关的api都会通过api这个路由导向到具体的路由 app.use('/api', apiRoutes) const HOST = process.env.HOST const PORT = process.env.PORT && Number(process.env.PORT) 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: { 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 FriendlyErrorsPlugin watchOptions: { poll: config.dev.poll, }, before(app) { app.get('/api/seller', (req, res) => { res.json({ errno: 0, data: seller })//接口返回json数据，上面配置的数据seller就赋值给data请求后调用 }), app.get('/api/goods', (req, res) => { res.json({ errno: 0, data: goods }) }), app.get('/api/ratings', (req, res) => { res.json({ errno: 0, data: ratings }) }) } }, 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 }), // copy custom static assets new CopyWebpackPlugin([ { from: path.resolve(__dirname, '../static'), to: config.dev.assetsSubDirectory, ignore: ['.*'] } ]) ] }) 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: ${devWebpackConfig.devServer.host}:${port}`], }, onErrors: config.dev.notifyOnErrors ? utils.createNotifierCallback() : undefined })) resolve(devWebpackConfig) } }) })
main.js完整代码如下：
