Hi.

I try use some post requests for another server (no, problem in not in cors-ajax)

var obj ={
    username: "admin",
    password: "admin"
}

wade.postObject( 'url/login', obj, function(callback){console.log(callback)} );

Recepient server work on node and wait json request:but what is:

wade.postObject send object as a plain text - it is feature or bug?

And how i can set custom headers to request?

I think is bag becasue jQuery same request 

$.ajax({
        url  :'url/login',
        type    :'POST',
        dataType:'json',
        data    : JSON.stringify(obj),
        contentType:"application/json",
        success: function(data, xhr){
            console.log(data)
        },
        error:function(xhr, ajaxOptions, thrownError){
           console.log(xnr)
        }
 });

Content-Type:application/json

And my API return true object
