如何将远程pdf文件上传到s3服务器

Question

我想将远程pdf文件上传到s3服务器。

我正在使用streaming-s3包。虽然它适用于其他网站但不适用于特定网站。（https://arxiv.org/pdf/1611.10012.pdf）

当我尝试从https://arxiv.org网站上传pdf文件时，它无法在s3服务器上传。

这是我将pdf文件上传到s3服务器的代码

var streamingS3 = require('streaming-s3');
  var awsHeader = {
        Bucket: bucket,
        Key: '1611.10012.pdf',
        ContentType: 'application/pdf',
        ACL: 'public-read'
    };

var url = "https://arxiv.org/pdf/1611.10012.pdf";

    var fileReadStream = request.get(url);
   console.log("parsing url : " + url);         
   uploadFile(fileReadStream, awsHeader, cb);


var uploadFile = function (fileReadStream, awsHeader, cb) {   

    //set options for the streaming module
    var options = {
        concurrentParts: 2,
        waitTime: 20000,
        retries: 2,
        maxPartSize: 10 * 1024 * 1024
    };
    //call stream function to upload the file to s3
    var uploader = new streamingS3(fileReadStream, config.aws.accessKey, config.aws.secretKey, awsHeader, options);
    //start uploading
    uploader.begin();// important if callback not provided.

    // handle these functions
    uploader.on('data', function (bytesRead) {
        //console.log(bytesRead, ' bytes read.');
    });

    uploader.on('part', function (number) {
        //console.log('Part ', number, ' uploaded.');
    });

    // All parts uploaded, but upload not yet acknowledged.
    uploader.on('uploaded', function (stats) {
        //console.log('Upload stats: ', stats);
    });

    uploader.on('finished', function (response, stats) {
        console.log(response);
        cb(null, response);
    });

    uploader.on('error', function (err) {
        console.log('Upload error: ', err);
        cb(err);
    });

};

我也试过这个网站的其他代码，但它也没有将文件上传到s3服务器。

var options = {
    url: 'https://arxiv.org/pdf/1611.10012.pdf',
    headers: {
        'Referer': 'https://arxiv.org',
        'User-Agent': 'stagefright/1.2 (Linux;Android 5.0)'
    }
}

request(options, function (error, response, body) {
  console.log('error:', error);
  console.log('statusCode:', response && response.statusCode);
  uploadFile(body, awsHeader, cb);
});

任何想法为什么s3上传不适用于特定网站（https://arxiv.org/pdf/1611.10012.pdf）？
