PHP应该生成什么来回馈jQuery AJAX请求？

Question

Perhaps it's a syntax error, but I never assume that. I have a -dead- simple AJAX test set up:

http://www.mcphersonindustries.com/bucket/api.php is a file with simply:

<?php echo "test"; ?>

And I have Apache as localhost with this jQuery bit running:

$(document).ready(function() {

function doAjaxPost() {  
    $.ajax({  
       type: "POST",  
       url: "http://www.mcphersonindustries.com/bucket/api.php",  
       data: "null",  
       success: function(resp){   
           console.log("Response: '" + resp + "'");  
       },  
       error: function(e){  
           console.log('Error: ' + e);  
       }  
    });  
}  

doAjaxPost();

});

So Firebug spits out Response: '' each time, but nothing's coming through the request. Do I need to declare a header in PHP? Am I making a boneheaded mistake somewhere?

Thanks for the insights, as always.

You can't do cross-site AJAX without that domain authorizing you:
