Node.js npm streaming-s3，从request.get（）流式传输图像

我正在测试，并试图通过请求上传基本教程。开始工作

目前，它一直处于停滞状态，从未启动、崩溃或发生任何事情

我的代码：

var elem = list.shift();
  console.log(elem._id+" "+elem.main_img); //elem contains exactly what it should
  var rStream = request.get(elem.main_img);
  uploader = new StreamingS3(rStream, {accessKeyId:'XXXXXX', secretAccessKey:'XXXXXXX',region:"eu-west-1"},
    {
      Bucket: 'xxxxxx-myimages',
      Key: elem._id,
      ContentType: 'image/jpeg',
      ACL:'public-read'
    },
    {
      concurrentParts: 2,
      waitTime: 10000,
      retries: 1,
      maxPartSize: 10*1024*1024,
    }
  );

  uploader.begin(); // important if callback not provided.

  uploader.on('data', function (bytesRead) {
    console.log(bytesRead, ' bytes read.');
  }).on('part', function (number) {
    console.log('Part ', number, ' uploaded.');
  }).on('uploaded', function (stats) {
    console.log('Upload stats: ', stats);
  }).on('finished', function (resp, stats) {
    console.log('Upload finished: ', resp);
  }).on('error', function (e) {
    console.log('Upload error: ', e);
  });

它基本上是一个填空的复制粘贴。。。是什么导致它不工作，也不显示任何输出？我检查了请求，它回复了200状态码。Console.log上传程序显示所有已正确填写的内容…

您确定列表中已设置所有内容吗？以下是我的控制台输出：

下面是我如何修改您的文件，基本上添加了一个静态元素，并更改了从shell获取的访问信息：

var list = [{main_img: 'http://cdn.sstatic.net/stackoverflow/img/sprites.png?v=3c6263c3453b', _id: '123'}];

var request = require('request');
var StreamingS3 = require('streaming-s3');
var elem = list.shift();
console.log(elem._id+" "+elem.main_img); //elem contains exactly what it should
var rStream = request.get(elem.main_img);
uploader = new StreamingS3(rStream, {accessKeyId:process.env.S3_ACCESS_KEY, secretAccessKey:process.env.S3_SECRET,region:process.env.S3_REGION},
    {
        Bucket: process.env.S3_BUCKET,
        Key: elem._id,
        ContentType: 'image/jpeg',
        ACL:'public-read'
    },
    {
        concurrentParts: 2,
        waitTime: 10000,
        retries: 1,
        maxPartSize: 10*1024*1024,
    }
);

uploader.begin(); // important if callback not provided.

uploader.on('data', function (bytesRead) {
    console.log(bytesRead, ' bytes read.');
}).on('part', function (number) {
    console.log('Part ', number, ' uploaded.');
}).on('uploaded', function (stats) {
    console.log('Upload stats: ', stats);
}).on('finished', function (resp, stats) {
    console.log('Upload finished: ', resp);
}).on('error', function (e) {
    console.log('Upload error: ', e);
});

你在windows或其他什么系统上吗？

不，是Unix。。。奇怪的是，我在KnoxS3库中遇到了类似的问题，当我使用http模块而不是请求时，这两个问题都消失了。。。http.get流到s3，而不是request.get。请求的版本是什么？嗯，我从npm得到了最新的。我修改过的程序对你有用吗？也许试一下，然后一行一行地换，看看哪里断了。首先设置环境变量，如

S3\u BUCKET=mybucket S3\u ACCESS\u KEY=xxxxxxx S3\u SECRET=xxxxxxx S3\u REGION=us-east-1 node script.js

var list = [{main_img: 'http://cdn.sstatic.net/stackoverflow/img/sprites.png?v=3c6263c3453b', _id: '123'}];

var request = require('request');
var StreamingS3 = require('streaming-s3');
var elem = list.shift();
console.log(elem._id+" "+elem.main_img); //elem contains exactly what it should
var rStream = request.get(elem.main_img);
uploader = new StreamingS3(rStream, {accessKeyId:process.env.S3_ACCESS_KEY, secretAccessKey:process.env.S3_SECRET,region:process.env.S3_REGION},
    {
        Bucket: process.env.S3_BUCKET,
        Key: elem._id,
        ContentType: 'image/jpeg',
        ACL:'public-read'
    },
    {
        concurrentParts: 2,
        waitTime: 10000,
        retries: 1,
        maxPartSize: 10*1024*1024,
    }
);

uploader.begin(); // important if callback not provided.

uploader.on('data', function (bytesRead) {
    console.log(bytesRead, ' bytes read.');
}).on('part', function (number) {
    console.log('Part ', number, ' uploaded.');
}).on('uploaded', function (stats) {
    console.log('Upload stats: ', stats);
}).on('finished', function (resp, stats) {
    console.log('Upload finished: ', resp);
}).on('error', function (e) {
    console.log('Upload error: ', e);
});
