使用|usage

var retryPromise = require('simple-promise-retry') 
  //要重试的事情封装到一个无参数函数中，函数返回对应操作的Promise即可
  function getPromise(){
    return new Promise((resolve,reject)=>{
      setTimeout(function(){
        var result = Math.random()>0.9
        console.log(result)
        if(result){
          resolve(true)
        }else{
          reject(false)
        }
      },1000)
    })
  }
  //使用本库
  retryPromise(getPromise,5).then((result)=>{
    console.log(['succ',result])
  },(err)=>{
    console.log(['err:',err])
