https ajax cross,javascript - Cross Domain AJAX POST / HTTPS / Header Authentication? - Stack Overfl...

I have to issues:

1) I've tried using JsonP, but can't get POSTing to work. Essentially, I'm trying to authenticate with an API, passing a Base64-encoded namevaluepair in the header over HTTPS.

2) How do I pass this key/value in the header? Any help would be appreciated! Here is an example of what I want, though this obviously doesn't work:

// where does this go?

var headerString = 'user=' + encodeURIComponent(username + ':' + password);

$.ajax({

type: "POST",

url: "https://anotherurl.on.another.server/LOGIN",

data: "I have no data, I'm logging in with header authentication",

dataType: "json",

success: function(data) {

},

error: function(data){

}

});
