How to generate "Content-Type: application/octet-stream" with Zinc client

This post was updated on .

I thank in advance if anyone can help me.

The code below:

ZnClient new
url: 'http://127.0.0.1:5001/add?stream-channels=true';
addPart: (ZnMimePart fieldName: 'file' fileNamed: 'file.txt');
post.

generates the following response using netcat:

nc -l 5001
POST /add?stream-channels=true HTTP/1.1
User-Agent: Zinc HTTP Components 1.0
Content-Length: 194
Host: 127.0.0.1:5001
Content-Type: multipart/form-data;boundary=Boundary-Zn-IDMNDZTQ
Accept: */*

--Boundary-Zn-IDMNDZTQ
Content-Disposition: form-data;name="file";filename="file.txt"
Content-Length: 16
Content-Type: text/plain;charset=utf-8

file.txt content
--Boundary-Zn-IDMNDZTQ--

however I would like to get:

nc -l 5001
POST /add?stream-channels=true HTTP/1.1
User-Agent: Zinc HTTP Components 1.0
Content-Length: 194
Host: 127.0.0.1:5001
Content-Type: multipart/form-data;boundary=Boundary-Zn-IDMNDZTQ
Accept: */*

--Boundary-Zn-IDMNDZTQ
Content-Type: application/octet-stream
Content-Disposition: form-data;name="file";filename="file.txt"
Content-Length: 16

file.txt content
--Boundary-Zn-IDMNDZTQ--

I not figured out how to get the extra line "Content-Type: application / octet-stream" using Zinc.

Hi,

That is an odd request.

Can you produce it with curl ?

You could try to make your part something like this:

| part |
part := ZnMimePart fieldName: 'file' value: '123'.
part headers at: 'Content-Type' add: ZnMimeType imageJpeg.
part.

This creates two values for Content-Type.

Thanks Sven for your reply.

The curl I want reproduce with Zinc is:

curl 'http://localhost:5001/api/v0/add?stream-channels=true' \
-H 'content-type: multipart/form-data; boundary=a831rwxi1a3gzaorw1w2z49dlsor' \
-H 'Connection: keep-alive' \
--data-binary $'--a831rwxi1a3gzaorw1w2z49dlsor\r\nContent-Type: application/octet-stream\r\nContent-Disposition: file; name="file"; filename="file.txt"\r\n\r\nfile.txt contents--a831rwxi1a3gzaorw1w2z49dlsor--' --compressed

It is like an example in https://github.com/ipfs/js-ipfs-api#tooling.

I want to implement the ipfs add command in my project http://smalltalkhub.com/#!/~chicoary/SmallIPFS/.

Hello!

Here is a code snippet:

At the trivial pülace you can set whatever mime type yout think will work for you.

I hope this helps.

Robert

--------------------------------------------------------------

sendFile

|contents stream |

stream := FileStream readOnlyFileNamed: self file.

stream binary.

contents := stream contents.

stream close.

self requestContext respond: [ :response |

response

contentType: 'application/x-msdownload';

document: contents;

attachmentWithFileName: self fileName

OK. I'm an idiot. This is server code, so, another business....

Re: How to generate "Content-Type: application/octet-stream" with Zinc client

In reply to this post by chicoary

From your netcat output I inferred that you wanted two content-type headers, but I don't think you do, I guess you just want to control the content-type.

When creating a ZnPart based on a file, the content-type is inferred automatically from the filename's extension.

The simplest solution is to use an unknown file type, like .bin or .dat which will result in a content-type of application/octet-stream (the default).

ZnMimePart fieldName: 'file' fileNamed: '/tmp/foo.bin'.

You could try setting the content-type after creation.

| part |
part := ZnMimePart fieldName: 'file' fileNamed: '/tmp/foo.txt'.
part headers contentType: ZnMimeType default.
part.

The methods #setContentType: could be added to ZnMimePart, I guess.

Re: How to generate "Content-Type: application/octet-stream" with Zinc client

This post was updated on .

Sven, with the code you suggested inserted in context of my project SmallIPFS

add: aFilePath
^ZnClient new
url: prefix , '/add?stream-channels=true';
addPart: ((ZnMimePart fieldName: 'file' fileNamed: aFilePath) headers contentType: ZnMimeType default);
post.

and invoking

ipfs add: 'file.txt'

I get

nc -l 5001
POST /api/v0/add?stream-channels=true HTTP/1.1
User-Agent: Zinc HTTP Components 1.0
Content-Length: 176
Host: 127.0.0.1:5001
Content-Type: multipart/form-data;boundary=Boundary-Zn-BCJQCIUT
Accept: */*

--Boundary-Zn-BCJQCIUT
Content-Disposition: form-data;name="file";filename="file.txt"
Content-Length: 16
Content-Type: application/octet-stream

--Boundary-Zn-BCJQCIUT--

Very good!

Thanks a lot.
