【问题描述】：

我进行 Ajax 调用：

Ext.Ajax.request(
            url : 'http://apps.dhis2.org/demo/dhis-web-commons-security/login.action',
            callbackKey : 'callback',
            method : 'POST',
            params : 
                j_username : username,
                j_password : password
            ,
            withCredentials : true,
            useDefaultXhrHeader : false,

            success : function(response) 
                var text = response.responseText;
                Ext.Msg.alert('Success', "Success login", Ext.emptyFn);
            ,

            failure : function(response) 
                var text = response.responseText;
                Ext.Msg.alert('Error', "Failure login", Ext.emptyFn);
            
        );

有响应头：

Connection:Keep-Alive
Content-Length:0
Content-Type:text/plain
Date:Fri, 21 Jun 2013 01:23:51 GMT
Keep-Alive:timeout=5, max=100
Location:http://apps.dhis2.org/demo/
Set-Cookie:JSESSIONID=2E5D7C7235BE37150F1FE7B30EA0244D; Path=/demo/; HttpOnly
Vary:cookie

我怎样才能获得 Location 标头？

当我尝试这样做时：

Ext.Ajax.on('requestcomplete',
        function(conn, response, options, eOpts) 
            var location = options.headers['Location'];
            Ext.Msg.alert('Success', location, Ext.emptyFn);
        , this);

我有错误

无法读取未定义的属性“位置”

            params : 
                j_username : username,
                j_password : password
            ,
            withCredentials : true,
            useDefaultXhrHeader : false,

            success : function(response) 

                var Location = response.getResponseHeader('Location');
            ,

            failure : function(response) 
                Ext.Msg.alert('Error', "Failure login", Ext.emptyFn);
            
        );
