empty request bodies with file upload to Node/Expr

Question

I'm using ng-flow to upload a picture.

I need to set my upload to content type application/json: Node (Express) request body empty but how?

I'm basing my code off the sample here:

https://github.com/flowjs/flow.js/tree/master/samples/Node.js

I'm guessing its in the header configuration, but I'm guessing. here is my $scope.image object:

    { 
    image:  { 
    support: true
    supportDirectory: true
    files: 
    [  { 
    flowObj:  { 
    $ref: $
     } 
    file:  { 
    webkitRelativePath: 
    lastModifiedDate:  {  } 
    name: super-phillip (1).gif
    type: image/gif
    size: 931802
     } 
    name: super-phillip (1).gif

     }  ]

     }

     }

the newest express bodyParser() doesn't allow multipart-formdata anymore so you have to use a middleware, like connect-multiparty or multer https://github.com/expressjs/multer
