Axios全局接口防抖、节流封装

import axios from 'axios'

function request(config) {
  const instance = axios.create({
    baseURL: 'http://localhost:3000/api',
    timeout: 10000
  })

// 防抖
const debounceTokenCancel = new Map()
instance.interceptors.request.use(config => {
  const tokenKey = `${config.method}-${config.url}`
  const cancel = debounceTokenCancel.get(tokenKey)
  if (cancel) {
    cancel()
  }
  return new Promise(resolve => {
    const timer = setTimeout(() => {
      clearTimeout(timer)
      resolve(config)
    }, 800)
    debounceTokenCancel.set(tokenKey, () => {
      clearTimeout(timer)
      resolve(new Error('取消请求'))
    })
  })
}, error => {
  console.log(error)
  return Promise.reject(error)
})

instance.interceptors.response.use(response => {
  return response
}, error => {
  console.log(error)
  return Promise.reject(error)
})

// 节流
let lastTime = new Date().getTime()
instance.interceptors.request.use(config => {
  const nowTime = new Date().getTime()
  if (nowTime - lastTime < 1000) {
    return Promise.reject(new Error('节流处理中，稍后再试'))
  }
  lastTime = nowTime
  return config
}, error => {
  console.log(error)
  return Promise.reject(error)
})

return instance(config)
}

export default request
