jquery美元。ajax自定义http头问题

I'm querying a REST webservice which uses custom http headers for authentication.

我正在查询一个使用自定义http头进行身份验证的REST web服务。

If I perform a POST without the headers I'm getting the expected error, but when I add the headers I get a 404 error instead of what I actually need.

如果我执行一个没有标题的帖子，我将得到预期的错误，但是当我添加标题时，我将得到一个404错误，而不是我实际需要的错误。

This is my code

这是我的代码

$.ajax({
  type: 'POST',
  url: 'http://server.com/service',
  beforeSend: function (xhr) { xhr.setRequestHeader('CUSTOM-HEADER-KEY', 'CUSTOM-HEADER-VALUE') },
  success: function(data) {    
    alert('success.');
  }
});

Here's the firebug headers output:

下面是firebug头输出:

OPTIONS /service HTTP/1.1 Host: server.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0.1) Gecko/20100101 Firefox/8.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Connection: keep-alive Origin: null Access-Control-Request-Method: POST Access-Control-Request-Headers: custom-header-key Pragma: no-cache Cache-Control: no-cache

选项/服务HTTP/1.1主机:server.com用户代理:Mozilla/5.0 (Windows NT 6.1;WOW64;Gecko/20100101 Firefox/8.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9，/;q=0.8 Accept- language: en-us,en

and the smae headers when performing the post with poster, which returns desired result.

以及smae在使用海报执行贴子时的标题，它返回期望的结果。

POST /service HTTP/1.1 Host: server.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0.1) Gecko/20100101 Firefox/8.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Connection: keep-alive CUSTOM-HEADER-KEY: CUSTOM-HEADER-VALUE Pragma: no-cache Cache-Control: no-cache Content-Length: 0

POST /service HTTP/1.1 Host: server.com用户代理:Mozilla/5.0 (Windows NT 6.1;WOW64;Gecko/20100101 Firefox/8.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9，/;q=0.8 Accept- language: en-us,en

The difference is pretty obvious, but I don't know what I'm doing wrong in the jquery code.

差别是很明显的，但是我不知道jquery代码中我做错了什么。

Could anyone help me please?

In a cross domain request if the header is not allowed by the service browser will simply remove it

在跨域请求中，如果服务浏览器不允许页眉，则只需删除它

At first browser browser will make an OPTION call to check for the allowed (Origin, Headers, Methods)

首先浏览器会发出一个选项调用来检查允许的(来源、标题、方法)
