axios分布式返回数据接口

对比常规请求与分布式请求：

export function doPackage(params) {return axios.post(package_url,params || {} )}
// 调用封装函数stepRequset()
export function doPackage (params, stepCallback, lastCallback, timeoutCallback) {
　　stepRequest(package_url, params || {}, stepCallback, lastCallback, 3600000, timeoutCallback)
}

分布拉取数据封装：

// import axios from 'axios';
import axios from './axios.js'

function makeUuid () {
  var s = []
  var hexDigits = '0123456789abcdef'
  for (var i = 0; i < 36; i++) {
    s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1)
  }
  // bits 12-15 of the time_hi_and_version field to 0010
  s[14] = '4'
  // bits 6-7 of the clock_seq_hi_and_reserved to 01
  s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1)
  s[8] = s[13] = s[18] = s[23] = '-'

  var uuid = s.join('')
  return uuid
}

export const getResponseStepList = (uuid, seqid) =>
  axios.post('/response/steplist', {
    step_track_uuid: uuid,
    step_next_seqid: seqid
  }).then(function (response) {
    return response
  })

class TimeoutChecker {
  constructor (timeoutMs) {
    this.timeoutMs = timeoutMs || 3600000
    this.restart()
  }

  restart () {
    this.startTime = this.getNowMs()
  }

  isTimeout () {
    return this.getNowMs() - this.startTime > this.timeoutMs
  }

  getNowMs () {
    return new Date().getTime()
  }
}

//
export const stepRequest = (
  url, // 要封装调用接口路径
  data, // 封装调用接口请求数据
  stepCallback, // 中间步骤response回调,参数为response json
  lastCallback, // 调用最后response回调,参数为response json
  timeoutMs, // 执行超时时间
  timeoutCallback // 超时回调,无参数
) => {
  let nextSeqid = 0
  let isSuccDone = false
  let timeoutChecker = new TimeoutChecker(timeoutMs)

  let uuid = makeUuid()

  data['step_track_uuid'] = uuid

  const doMainRequest = () => axios({
    url: url,
    method: 'post',
    data: data,
    timeout: 3600000
  }).then(function (response) {
    return response
  })

  const handleResponseList = (stepRes) => {
    for (let response of stepRes.data.response_list) {
      // eslint-disable-next-line
      stepCallback(eval('(' + response + ')'))
    }
  }

  const handleTimeout = () => {
    if (timeoutCallback) {
      let func = timeoutCallback
      timeoutCallback = null
      func()
    }
  }

  let interval = setInterval(() => {
    if (isSuccDone) {
      clearInterval(interval)
      handleTimeout()
    } else {
      if (timeoutChecker.isTimeout()) {
        clearInterval(interval)
        handleTimeout()
      } else {
        getResponseStepList(uuid, nextSeqid).then((stepRes) => {
          if (isSuccDone) {
            clearInterval(interval)
          } else {
            nextSeqid = stepRes.data.next_seqid
            handleResponseList(stepRes)
          }
        })
      }
    }
  }, 2000)

  doMainRequest().then(res => {
    if (!timeoutChecker.isTimeout()) {
      isSuccDone = true
      clearInterval(interval)
      getResponseStepList(uuid, nextSeqid).then((stepRes) => {
        handleResponseList(stepRes)
        lastCallback(res.data)
      })
    } else {
      handleTimeout()
    }
  })
}

引用：

import {stepRequest} from 'service/stepreq.js'

实际使用：

    doPackageHandle () {
      Var logMsg = ‘’ // 数组push也行
      var param = {//this.form
        'gitpath': this.form.gitpath,
        'branch': this.form.branch,
        'desc': this.form.desc,
      }

      var stepCallback = (res) => {
        if (res.err_code === '0') {
          // console.log(res,”正在打包中...");
          logMsg += res.info
        } else {
          logMsg = ‘打包失败’+res.err_desc
        }
      }
      var lastCallback = (res) => {
        if (res.err_code === '0') {
          // console.log(res,"成功”);
          logMsg += res.info
        } else {
          // console.log(res,"失败”);
          logMsg = ‘打包失败’+res.err_desc       
        }
      }

      var timeoutCallback = (res) => {
        // console.log(res,”超时");
      }

      doPackage(param, stepCallback, lastCallback, timeoutCallback)
    }
