Vue environment passes parameters to package different domain name code analysis

This time I will bring you an analysis of the code for packaging different domain names when passing parameters in the vue environment. What are the precautions for packaging different domain names when passing parameters in the vue environment? The following is a practical case, let's take a look.

Test environment: api-test.demo.com

Online production environment: api.demo.com,

This time it is packaged in the Vue.js project, Let me teach you how to do this:

Use

npm run build -- xxx to determine different environments and give different domain name configurations based on the passed parameter xxx.

1. Modification of /config/dev.env.js in the project:

Added: HOST: '"dev"'

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

2. Modification of /config/prod.env.js in the project:

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+'"'
}

3. Modification of ajax encapsulation in the project ：

/**
** 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;

4. Finally type the command:

npm run build -- test

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,

npm run build -- prod

apiUrl = 'http://api.demo.com'
