Vue config配置文件index 中代理设置
我们使用脚手架创建的项目，可以在config项目中看到
其中我们打开index.js文件
'use strict'
// Template version: 1.3.1
// see http://vuejs-templates.github.io/webpack for documentation.
const path = require('path')
module.exports = {
dev: {
// Paths
assetsSubDirectory: 'static',
assetsPublicPath: '/',
proxyTable: {
'/api': {
target: 'http://192.168.0.173:8080',
changeOrigin:true,//允许跨域
pathRewrite: {
'^/api': '/api'
}
}
},
// Various Dev Server settings
host: '0.0.0.0', // 代理会映射到本地的一个ip地址。这里我们可以通过改成根基的ip地址或者0.0.0.0然后通过手机就可以看到项目
port: 8080, // 这里是我们本地设置的一个端口号
autoOpenBrowser: false,
errorOverlay: true,
notifyOnErrors: true,
poll: false, // https://webpack.js.org/configuration/dev-server/#devserver-watchoptions-
/**
* Source Maps
*/
// https://webpack.js.org/configuration/devtool/#development
devtool: 'cheap-module-eval-source-map',
// If you have problems debugging vue-files in devtools,
// set this to false - it *may* help
// https://vue-loader.vuejs.org/en/options.html#cachebusting
cacheBusting: true,
cssSourceMap: true
},
build: {
// Template for index.html
index: path.resolve(__dirname, '../dist/index.html'),
// Paths
assetsRoot: path.resolve(__dirname, '../dist'),
assetsSubDirectory: 'static',
assetsPublicPath: '/',
/**
* Source Maps
*/
productionSourceMap: true,
// https://webpack.js.org/configuration/devtool/#production
devtool: '#source-map',
// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`, make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,
productionGzipExtensions: ['js', 'css'],
// Run the build command with an extra argument to
// View the bundle analyzer report after build finishes:
// `npm run build --report`
// Set to `true` or `false` to always turn it on or off
bundleAnalyzerReport: process.env.npm_config_report
}
}
其中proxyTable就是创建项目所自带的代理，当我们运行dev的时候，就会通过访问代理来间接访问我们的api。只需要添加属性changeOrigin:true 就可以实现跨域访问。同时可以提高安全系数。也省去了我们自定义请求文件时，所添加的主域！
