Multipart data (json +file)

General
1

Hello
I want to send HTTP post request that has json + file upload. Can I do it in one shot? Or I have to send json first and then attachment (file)?

Can someone please guide?

Search the forum for multipart.

Here is one such example : Form-data multipart-encoded request with pdf file attached into the body

`I have referred the page you have recommended. Can you please tell me whats going wrong?

[{"id":"a12f24af.f30b98","type":"function","z":"5b4e4e9f.708f4","name":"","func":"msg.headers = {\n 'content-type' : 'multipart/form-data'\n}\n\nmsg.payload = {\n file: {\n field: 'file',\n data: msg.payload.byteArray,\n type: 'binary',\n name: msg.payload.fname\n },\n formOptions: {\n ideaName: 'idea1',\n problemDescription:'problem1'\n }\n}","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":,"x":370,"y":340,"wires":[["412c3b14.67b054"]]}]

I am using fileinject which passes msg.payload to a function. My function looks like this

var fileData = msg.payload;
var msg1,msg2

var data={ "ideaName": "idea1",
"problemDescription":"test"};
msg.headers = {'Content-Type': 'multipart/form-data'};

msg1 = {payload: {JSONString: JSON.stringify(data)}} ;

msg2={payload:{

'image' : {
    'value': fileData,
    'options': {
        'filename': 'mytest.txt'
    }
}

}

}

return[msg,[msg1,msg2]];

But this sends only file paylod to HTTP request.

Any guidance?

That won't be multipart.

Check this other thread (that I found by searching multipart)...
