我想从jQuery向AJAX POST请求添加自定义标头.

我试过这个:

$.ajax({
    type: 'POST',
    url: url,
    headers: {
        "My-First-Header":"first value",
        "My-Second-Header":"second value"
    }
    //OR
    //beforeSend: function(xhr) { 
    //  xhr.setRequestHeader("My-First-Header", "first value"); 
    //  xhr.setRequestHeader("My-Second-Header", "second value"); 
    //}
}).done(function(data) { 
    alert(data);
});

当我发送此请求并使用FireBug观看时,我看到此标题:

选项xxxx/yyyy HTTP/1.1
主机:127.0.0.1:6666
User-Agent:Mozilla/5.0(Windows NT 6.1; WOW64; rv:11.0)Gecko/20100101 Firefox/11.0
接受:text/html,application/xhtml + xml, application/xml; q = 0.9,/ ; q = 0.8
Accept-Language:fr,fr-fr; q = 0.8,en-us; q = 0.5,en; q = 0.3
Accept-Encoding:gzip,deflate
Connection:keep -alive
Origin:null
Access-Control-Request-Method:POST
Access-Control-Request-Headers:my-first-header,my-second-header
Pragma:no-cache
Cache-Control:no-cache

为什么我的自定义标题会转到Access-Control-Request-Headers:

Access-Control-Request-Headers:my-first-header,my-second-header

我期待像这样的标头值:

My-First-Header:第一个值
My-Second-Header:第二个值

可能吗？
