节点存档在AWS Lambda中不起作用

Question

此代码在本地运行良好。但是，它在aws lambda环境中的行为并不奇怪。没有错误发生。 但是，它实际上不起作用。 （lambda） 不会引发节点归档器的输入和进度事件。有什么问题吗？

如有必要，我可以将代码推送到GitHub。

环境

• 节点v8.10
• 在Aws Lambda中
• 使用无服务器

'use strict';

const axios= require('axios')
const archiver= require('archiver')
const AWS = require('aws-sdk')

const { log } = console
const logging = value => log(value)
const errorHandler = logging

const loggingW = (value, b) => v2 => {
  if(b) console.log(value,v2)
}

const stream2 = (Bucket, Key) => {
  const stream = require('stream');
  const Body = new stream.PassThrough();
  s3.upload({
    Bucket, Key, Body,
  }, errorHandler)
  return Body
}

const s3 = new AWS.S3({
  accessKeyId: '===', secretAccessKey: '===' // ur key
})

const hello = async (event, context) => {

  const res = await axios({
    url: 'some image', // some image url
    responseType: 'stream'
  })

  const archive = archiver('zip')

  archive
    .on('entry', loggingW('a-e', true))
    .on('progress', loggingW('a-p', true))
    .on('warning', loggingW('a-w', true))
    .on('fininsh', loggingW('a-finish', true))
    .on('end', loggingW('a-end', true))
    .on('close', loggingW('a-close', true))
    .on('error', function(err) {
      console.log('archie', err)
      throw err;
    });

  const dest = stream2('bucket', 'ttt.zip')
  dest
    .on('drain', loggingW('a-d', false))
    .on('pipe', loggingW('s-p', false))
    .on('unpipe', loggingW('s-up', false))
    .on('close', loggingW('close', false))
    .on('finish', loggingW('s-f', false))
    .on('end', loggingW('end'))
    .on('error', loggingW('error', true))

  archive.pipe(dest)
  archive.append(res.data, { name: '/ok/tt.jpg' }).finalize()

  return {
    statusCode: 200,
    body: JSON.stringify({
      message: '1',
      input: event,
    }),
  };

  // Use this code if you don't use the http event with the LAMBDA-PROXY integration
  // return { message: 'Go Serverless v1.0! Your function executed successfully!', event };
};

module.exports.hello = hello

// hello()
