How to use AngularJS $http to send FormData

The FormData interface provides a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XHR Send method. It uses the same format a form would use if the encoding type were set to multipart/form-data.

var formData = new FormData();

formData.append('type', type);
formData.append('description', description);
formData.append('photo', photo); 

return $http({
    url: PATH_REST_SERVICES + '/nomeServizio',
    headers: {"Content-Type": undefined },
    data: formData,
    method: "PUT"
});

It is important to set the content type header to undefined. Normally the $http service sets the content type to application/json. When the content type is undefined, the XHR API will automatically set the content type to multipart/form-data with the proper multi-part boundary.
