Question

我正在尝试通过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请求的响应标头，它们似乎都完整无缺，并与在apache中声明的内容一致。我是否应该包含其他指令或以某种方式更改配置才能使其正常工作？

更新：问题的根源在于我同时希望example.com和www.example.com都发挥作用。有问题的网站在两个实例中的标头<base href="www.example.com" />中始终都有一个标记，因为这是默认网站框架的一部分。我发现删除此链接允许ajax请求在example.com上运行，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。对于任何可能对此处的含义有所了解的人，我都会粘贴下面的请求和响应标题。

以下是已移除<base>标记的标头。在这种情况下，ajax调用成功：

以下是<base>标记完整的标题。这些标头反映了ajax调用失败的情况。值得注意的是“地点”。响应标题中的字段表示＆＃39; https＆＃39;即使这不是通过https连接发生的：

Answer 1

根据MDN，您不能将通配符用于“凭证请求”，因此您的请求可能属于该类别。

CORS在Firefox中不起作用
