How to post multipart/form-data with node.js superagent

Question

I am trying to send the content-type in my superagent post request to multipart/form-data.

var myagent = superagent.agent();

myagent
  .post(\'http://localhost/         


        

Answer 1

Here is what worked for me. I had a single field form, that was uploading a file. I turned the form into a HTML5 FormData element and then did it as follows:

var frm = new FormData(document.getElementById('formId'));
var url =  'url/here';

superagent.post(url)                    
.attach('fieldInFormName', frm.get('fieldInFormName'))                                        
.end( function (error, response) {
    //handle response
});

Please note, I tried various ways of setting the 'Content-Type' manually in superagent, and it never worked correctly because of the multipart identifier needed in the Content-Type.
