file-upload - 在node.js上使用knox将八位位组流从请求流传输到S3

我正在尝试使用node.js上的knox将八位字节流直接流到S3。八位字节流是从浏览器上传的XHR文件。我以为我可以将请求流式传输到putStream中，并且一切都可以正常工作，但是可惜没有。

这是我的代码:

var client = knox.createClient({
           // AWS credentials here
         });
if (req.headers['content-type'].match(/application\/octet-stream/i)) {

  var filename = '/'+req.headers['x-file-name'];

  client.putStream(req, filename, function(err, res){
    // TODO: Catch errors
    body = '{"success":"true"}'
    res.writeHead(200,
      { 'Content-Type':'text/html'
      , 'Content-Length':body.length
      })
    res.end(body)
  });

}

和我收到的错误:

TypeError: Bad argument
    at Object.stat (fs.js:354:11)
    at Client.putStream (./lib/knox/client.js:181:6)

最佳答案

我正在做这样的事情:

app.post('/uploadAmazon', function(req, res) {
var params = req.query;

var request = client.request("PUT", '/' + req.header('x-file-name') + '?partNumber=' + params.partNumber
        + '&uploadId=' + params.uploadId, {
    'Content-Length' : req.header('Content-Length')
} );

req.on('data', function(data){
    request.write(data);
});


request.on('response', function(response) {
    console.log('Partial ' + params.partNumber + ' statusCode: ' + response.statusCode);
    if (response.statusCode== 200) {
        uploadMap[params.id].currentSize++;
        uploadMap[params.id].completeXmlArray[+(params.partNumber) - 1] = '<Part><PartNumber>' + params.partNumber + '</PartNumber><ETag>' + response.headers.etag + '</ETag></Part>' ;

        if (uploadMap[params.id].currentSize == uploadMap[params.id].totalSize) {
            uploadMap[params.id].uploadId = params.uploadId;
            completeSend(uploadMap[params.id]);
        }
    }
}).end();

res.end();

});

假设我从帖子中收到了文件名，部件号和uploadId。
