Select different domain names according to the environment parameter passing method

This time I will introduce to you the methods of selecting different domain names according to the environment parameter passing method and selecting different domain names according to the environment passing parameter method. During project development, the front-end is very troubled when configuring the back-end api domain name. It often appears:

Local development environment: api-dev.demo.com

Test environment: api-test.demo.com

Online production environment: api.demo.com,

This time it is packaged in the Vue.js project, and I will teach you how to do it:

Use

, according to the passed parameter xxx to determine different environments and give different domain name configurations.

Added: HOST: '"dev"'

'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')
module.exports = merge(prodEnv, {
 NODE_ENV: '"development"',
 HOST: '"dev"'
})

Get the parameters passed in:

'use strict'
let HOST = process.argv.splice(2)[0] || 'prod';
console.log(HOST);
module.exports = {
 NODE_ENV: '"production"',
 HOST: '"'+HOST+'"'
}

/**
** 设置API接口域名
**/
let apiUrl = '';
// 根据 process.env.HOST 的值判断当前是什么环境
// 命令：npm run build -- test ，process.env.HOST就设置为：'test'
let HOST = process.env.HOST;
HOST = HOST === 'prod' ? '' : '-' + HOST;
apiUrl = 'http://api'+HOST+'.demo.com';
axios.defaults.baseURL = apiUrl;

Note – Yes 2 horizontal bars, followed by parameters, so process.env.HOST will get the parameter 'test',

apiUrl = 'http://api-test.demo.com'

If prod is released and packaged online,

<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">apiUrl = 'http://api.demo.com'</pre><div class="contentsignin">Copy after login</div></div> I believe you have mastered the method after reading the case in this article.
