1、api.request.js

import axios from 'axios'
// import store from '@/store'

/*添加错误监控*/
const addErrorLog = errorInfo => {
  const { statusText, status, request: { responseURL } } = errorInfo
  let info = {
    type: 'ajax',
    code: status,
    mes: statusText,
    url: responseURL
  }
  if (!responseURL.includes('save_error_logger')) {
    // 上报错误信息
    // store.dispatch('addErrorLog', info)
    console.log(info)
  }
}

class HttpRequest {
  constructor (baseUrl = baseURL) {
    this.baseUrl = baseUrl
    this.queue = {} //请求队列控制标记
  }
  getInsideConfig () {
    const config = {
      baseURL: this.baseUrl,
      headers: {
        //
        'Content-Type': 'application/json;charset=UTF-8'
      }
    }
    return config
  }
  destroy (url) {
    delete this.queue[url]
    if (!Object.keys(this.queue).length) {
      // Spin.hide()
    }
  }
  interceptors (instance, url) {
    // 请求拦截
    instance.interceptors.request.use(config => {
      // 添加全局的loading...
      if (!Object.keys(this.queue).length) {
        // Spin.show() // 请求中Loading效果不建议开启，因为界面不友好
      }
      this.queue[url] = true
      return config
    }, error => {
      return Promise.reject(error)
    })
    // 响应拦截
    instance.interceptors.response.use(res => {
      this.destroy(url)
      const { data, status } = res
      return { data, status }
    }, error => {
      this.destroy(url)
      let errorInfo = error.response
      if (!errorInfo) {
        const { request: { statusText, status }, config } = JSON.parse(JSON.stringify(error))
        errorInfo = {
          statusText,
          status,
          request: { responseURL: config.url }
        }
      }
      addErrorLog(errorInfo)
      return Promise.reject(error)
    })
  }
  request (options) {
    const instance = axios.create()
    options = Object.assign(this.getInsideConfig(), options)
    this.interceptors(instance, options.url)
    return instance(options)
  }
}
export default HttpRequest

2、axios.js

import HttpRequest from '@/libs/axios'
// import config from '@/config'
// const baseUrl = process.env.NODE_ENV === 'development' ? config.baseUrl.dev : config.baseUrl.pro
const baseUrl = process.env.NODE_ENV === 'development' ? 'http://localhost:8090/' : '/';

const axios = new HttpRequest(baseUrl)
export default axios

3、调用示例 user.js

import axios from './lib/api.request'

export const Login = (userName, password) => {
    return axios.request({
        url: 'user/login',
        data: {
            userName,
            password
        }
    })
}
