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](https://discourse.nodered.org/t/form-data-multipart-encoded-request-with-pdf-file-attached-into-the-body/44749)

</div>

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** )...

> That isn't 100% true. The HTTP In node does support file uploads now - select Post and tick the box to enable file uploads. To send a multipart upload from the HTTP Request node is more work, but doable. Here's a Function that will construct a suitable message to pass to the HTTP Request node: msg.headers = { "Content-Type": "multipart/form-data; boundary=------------------------d74496d66958873e" } msg.payload = '--------------------------d74496d66958873e\r\n'+ 'Content-Disposition: fo…
