C# 在Firefox中对启用AJAX的WCF服务启用Windows身份验证不工作

我的网站启用了

Windows身份验证

和

匿名身份验证

，数据库连接也使用Windows身份验证（基于用户登录）

我调用了支持AJAX的WCF服务，它是匿名身份验证的

在IE上一切正常。但当我用Firefox打开它时，引发了一个异常：

用户“NT授权\匿名登录”登录失败

Web.config

我想这一页可以帮助你

每当您试图通过javascript或jquery调用跨域WCF服务时，它在不同的浏览器中的行为会有所不同。当您想使用jquery/javascript或ajax对跨域wcf服务或普通服务执行“POST”或“GET”请求时，浏览器实际上会向wcf服务发送一个“选项”动词调用，而wcf方法属性中没有提到该调用
