Difficulty with adding files using HTTP request on meteor server side

Good day,

I’ve spent some time trying to upload file to ipfs using http request (from meteor).

Meteor.startup(() => {
  // code to run on server at startup
                "getFile": function(){
                        var results = HTTP.get('', {timeout:5000, params:
                        {"arg": "QmcNHzJeDphzamLVgKq1R3wmFXqw8EbWLVS6qhAPGohobM",
                        "encoding": "json"}});
                        return (results)
                "uploadFile": function(){
                        var results = HTTP.post("", {timeout:5000, params:{
                        "path": "/home/shultzi/trial.txt",
                        "stream-channels": "true",
                        "arg": "/home/shultzi/trial.txt",
                        //"Content-Type": "multipart/mixed",
                        //"file": "trial.txt"
                        //"Content-Type": "multipart/form-data"

                        }, header: {
                        //"Content-Type": "application/octet-stream",
                        "enctype": "multipart/form-data",
                        "Content-Type": "multipart/form-data",
                    return (results)


The first http request (getFile) works just fine, but when I’m trying to upload the file I constantly get the error message “File argument ‘path’ is required”. I’ve tried to modify my http request in many ways, adding stream-channels and changing multipart, but nothing seems to work.

I know there’re some js apis out there, but I really want to work with my own http requests.

I’ll highly appreciate any type of help, suggestion or insight you might have!

The way I’d go to debug this is tcpdump using curl -F file=@/home/shultzi/trial.txt... to upload that file and then do the same using your code. Compare both dumps and see where is the difference.

The error would suggest that there is no “file” field in your multipart form-data, but would need to tcpdump to be sure…
