asp.net-mvc-3 – 使用Razor视图抛出有关DotNetOpenAuth.IEmbeddedResourc

当我的Razor视图调用@ Html.OpenIdSelector时(…我得到一个InvalidOperationException：

The current IHttpHandler is not one of
types: System.Web.UI.Page,
DotNetOpenAuth.IEmbeddedResourceRetrieval.
An embedded resource URL provider must
be set in your .config file.

我应该在配置文件中设置什么？

解决方法

>在解决方案资源管理器中右键单击Web项目的引用
>添加库包参考…
>单击“在线”选项卡.
>在搜索框中键入dotnetopenauth
>单击“安装”

一切都将自动设置,正确的组件将从互联网上下载并作为参考添加.

以下是执行此操作后web.config文件的外观：

更新：

您可以实现自定义资源检索提供程序：

public class CustomResourceProvider : IEmbeddedResourceRetrieval
{
    public Uri GetWebResourceUrl(Type someTypeInResourceAssembly,string manifestResourceName)
    {
        return new Uri("http://www.google.com");
    }
}

然后在web.config中注册它：

<dotNetOpenAuth>
    <webResourceUrlProvider type="AppName.CustomResourceProvider,AppName" />
    ...
</dotNetOpenAuth>

但我建议您使用openid-selector库生成登录表单.
