CORS在Firefox中不起作用

Question

我试图通过ajax将数据加载到jQuery对话框中,但Firefox中的请求失败(34.0.5).工作正常,我在Chrome和Safari中没有任何抱怨.

我的apache conf包含:

Header set Access-Control-Allow-Origin "*" 
Header set Access-Control-Allow-Methods: "PUT, GET, POST, DELETE, OPTIONS"
Header set Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept"

jQuery很简单:

$('#dialog').load('example.php', function() { $('#dialog').dialog('open'); });

Firefox响应以下控制台错误:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://www.example.com/example.php. This can be fixed by moving the resource to the same domain or enabling CORS.

检查来自ajax请求的响应头,它们似乎都是完整的,并且与apache中声明的内容一致.我是否应该包含一些其他指令或以某种方式更改配置以使其工作？

更新:问题的根源是我喜欢这两个example.com并且www.example.com功能相同的事实.有问题的站点在<base href="www.example.com" />两个实例的标头中始终都有一个标记,因为这是默认站点框架的一部分.我已经发现删除此链接允许ajax请求在example.com上工作,即使它仍然专门从www子域调用资源.

有趣的是,删除此标记时,请求和响应标头的许多方面都会发生变化.对于任何可能对这里的含义有所了解的人我都会在下面粘贴请求和响应标头.

以下是已<base>删除标记的标头.在这种情况下,ajax调用成功:

Answer 1

根据MDN，您不能将通配符用于“凭据请求”，因此您的请求可能属于该类别。
