jquery - 在 jQuery AJAX GET 调用中传递请求 header

Question

我正在尝试使用 jQuery 在 AJAX GET 中传递请求 header 。在接下来的 block 中，“数据”自动传递查询字符串中的值。有没有一种方法可以改为在请求 header 中传递该数据？

$.ajax({
         url: "http://localhost/PlatformPortal/Buyers/Account/SignIn",
         data: { signature: authHeader },
         type: "GET",
         success: function() { alert('Success!' + authHeader); }
      });

下面的也不行

$.ajax({
         url: "http://localhost/PlatformPortal/Buyers/Account/SignIn",
         beforeSend: { signature: authHeader },
         async: false,                    
         type: "GET",
                    success: function() { alert('Success!' + authHeader); }
      });

从 jQuery 1.5 开始，有一个 headers 哈希，您可以按如下方式传入:

$.ajax({
    url: "/test",
    headers: {"X-Test-Header": "test-value"}
});

来自 http://api.jquery.com/jQuery.ajax :

headers (added 1.5): A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.
