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？

我试图在另一个应用程序(spring-boot应用程序)上调用REST端点(angularjs).应用程序在以下主机和端口上运行.

• REST应用程序,使用spring boot, http://localhost:8080
• HTML应用程序,使用angularjs, http://localhost:50029

我也在使用spring-securityspring-boot应用程序.从HTML应用程序,我可以对REST应用程序进行身份验证,但此后,我仍然无法访问任何REST端点.例如,我有一个如下定义的angularjs服务.

adminServices.factory('AdminService', ['$resource', '$http', 'conf', function($resource, $http, conf) {
    var s = {};
    s.isAdminLoggedIn = function(data) {
        return $http({
            method: 'GET',
            url: 'http://localhost:8080/api/admin/isloggedin',
            withCredentials: true,
            headers: {
                'X-Requested-With': 'XMLHttpRequest'
            }
        });
    };
    s.login = function(username, password) {
        var u = 'username=' + encodeURI(username);
        var p = 'password=' + encodeURI(password);
        var r = 'remember_me=1';
        var data = u + '&' + p + '&' + r;

        return $http({
            method: 'POST',
            url: 'http://localhost:8080/login',
            data: …
