基于vue cli 通过命令行传参实现多环境配置

const webpack = require('webpack')
const environment = require('./build/environment')
module.exports = {
 baseUrl: '/wxperp/',
 configureWebpack: {
 plugins: [
 new webpack.DefinePlugin({
 'process.env.STAGE': JSON.stringify(environment.stage),
 'process.env.LOCAL_URL': JSON.stringify(environment.localUrl)
 })
 ]
 }
}

const os = require('os')
// 获取命令行变量
const configArgv = JSON.parse(process.env.npm_config_argv)
const original = configArgv.original.slice(1)
const stage = original[1] ? original[1].replace(/-/g, '') : ''
// 本地ip地址
let localUrl
try {
 const network = os.networkInterfaces()
 localUrl = network[Object.keys(network)[0]][1].address
} catch (e) {
 localUrl = 'localhost'
}
localUrl = 'http://' + localUrl + '/'

module.exports = {
 stage, localUrl
}

(() => {
 const urlMap = {
 local: process.env.LOCAL_URL + 'api',
 sit: 'http://xxx.xxx.xxx:xxxx/sit/api',
 uat: 'http://xxx.xxx.xxx:xxxx/uat/api',
 prod: 'http://xxx.xxx.xxx:xxxx/prod/api'
 }
 //sit,uat,prod
 let stage = process.env.STAGE
 //development,production
 const nodeEnv = process.env.NODE_ENV
 //nodeEnv为production并且stage不存在默认为生产环境
 if (nodeEnv === 'production' && !stage) {
 stage = 'prod'
 } else {
 //stage不存在默认为本地开发环境
 stage = stage || 'local'
 }
 console.log('ip:' + urlMap[stage])
})()
