可以用配置解决的问题，请勿硬编码
姊妹篇 jQuery进阶：用最优雅的方式写ajax请求

axios是Vue官方推荐的ajax库, 用来取代vue-resource。

优点：

• 增加一个ajax接口，只需要在配置文件里多写几行就可以

• 统一管理配置

1. content-type配置

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

2. api 配置

// 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'
      }
    }
  ]
}

3. request.js 方法

// 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 = {}

function render (tpl, data) {
  var re = /{{([^}]+)?}}/
  var match = ''

  while ((match = re.exec(tpl))) {
    tpl = tpl.replace(match[0], data[match[1]])
  }

  return tpl
}

function fire (query = {}, payload = '') {
  // qs 特别处理 formData类型的数据
  if (this.contentType === contentType.formData) {
    payload = qs.stringify(payload)
  }

  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

4. 在组件中使用

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

浏览器结果：

Request URL:http://192.168.40.231:30412/api/security/login??heiheihei
Request Method:POST
