axios를 사용하여 Ajax 요청을 구현하는 방법(자세한 튜토리얼)

// filename: content-type.js
module.exports = {
 formData: 'application/x-www-form-urlencoded; charset=UTF-8',
 json: 'application/json; charset=UTF-8'
}

// filename: api-sdk-conf.js
import contentType from './content-type'
export default {
 baseURL: 'http://192.168.40.231:30412',
 apis: [
 {
  name: 'login',
  path: '/api/security/login?{{id}}',
  method: 'post',
  contentType: contentType.formData,
  status: {
  401: '用户名或者密码错误'
  }
 }
 ]
}

// request.js
import axios from 'axios'
import qs from 'qs'
import contentType from '@/config/content-type'
import apiConf from '@/config/api-sdk-conf'
var api = {}
// render 函数用来渲染路径上的变量, 算是一个微型的模板渲染工具
// 例如render('/{{userId}}/{{type}}/{{query}}', {userId:1,type:2, query:3})
// 会被渲染成 /1/2/3
function render (tpl, data) {
 var re = /{{([^}]+)?}}/
 var match = ''
 while ((match = re.exec(tpl))) {
 tpl = tpl.replace(match[0], data[match[1]])
 }
 return tpl
}
// fire中的this, 会动态绑定到每个接口上
function fire (query = {}, payload = '') {
 // qs 特别处理 formData类型的数据
 if (this.contentType === contentType.formData) {
 payload = qs.stringify(payload)
 } 
 // 直接返回axios实例，方便调用then,或者catch方法
 return axios({
 method: this.method,
 url: render(this.url, query),
 data: payload,
 headers: {
  contentType: this.contentType
 }
 })
}
apiConf.apis.forEach((item) => {
 api[item.name] = {
 url: apiConf.baseURL + item.path,
 method: item.method,
 status: item.status,
 contentType: item.contentType,
 fire: fire
 }
})
export default api

import api from '@/apis/request'
...
  api.login.fire({id: '?heiheihei'}, {
  username: 'admin',
  password: 'admin',
  namespace: '_system'
  })
...
