Help request: Sending stream with unknown length about form-data HOT 4 CLOSED

Where are you sending the file? FormData could be bent to send stream of data without final length, it's done using chunked encoding. But when I tested it, only node.js server were able to receive POST upload with chunked encoding. Otherwise you need to provide Content-Length header, so receiving end would accept it.

Thanks for the quick reply Alex.

I posted a request for help over at Busboy too. This was the developer's response

"There is no Content-Length for individual files/parts. That's what multipart is, parts separated by boundaries, not separated by pre-defined content lengths."

I'm sure that what I'm trying to do should be possible but I'm lost as to how to do it.

@m1sta looks like they confused multipart and chunked encoding. Former one allows to send different parts (pieces of the content with separate headers, content-types, etc), but you still need to provide content-length for the whole request – this is what FormData does. Latter allows to split request (multipart or not) into chunks (not necessary chunk per file/part, but more like streaming) and send request to the receiver without specifying total content-length, but rather prepend each chunk with it's own size.

Now the question is can the receiver end (server where you're trying to upload your stuff) understand (and accept) POST request with chunked encoding (many servers don't).

Do you have any simplified test you can share with me?
If I remember correctly FormData can send stuff out in chunked encoding without too many changes (if it's not already there), so it's matter of understanding what side is causing problems. :)

Because it's been a while, I'm going to close this pull request.
Please don't hesitate to continue discussion here whenever you have time.
Thank you.
