Question

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

目前的IHttpHandler不是其中之一类型：System.Web.UI.Page， DotNetOpenAuth.IEmbeddedResourceRetrieval。嵌入式资源URL提供程序必须在你的.config文件中设置。

我应该在config文件中设置什么？

Answer 1

~~只需NuGet DotNetOpenAuth个套件。它将在配置文件中设置您需要的所有内容：~~

右键单击解决方案资源管理器中的Web项目的References

Add Library Package Reference...

点击Online标签。

在搜索框中输入dotnetopenauth

点击Install

将自动设置所有内容，并从互联网上下载正确的程序集并添加为参考。

以下是执行此操作后web.config文件的样子：

<?xml version="1.0" encoding="utf-8"?>  <configuration> <configSections> <section name="uri" type="System.Configuration.UriSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> <section name="dotNetOpenAuth" type="DotNetOpenAuth.Configuration.DotNetOpenAuthSection" requirePermission="false" allowLocation="true" /> </configSections> <connectionStrings> <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" /> </connectionStrings> <appSettings> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> </appSettings> <system.web> <compilation debug="true" targetFramework="4.0"> <assemblies> <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </assemblies> </compilation> <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication> <membership> <providers> <clear /> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" /> </providers> </membership> <profile> <providers> <clear /> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" /> </providers> </profile> <roleManager enabled="false"> <providers> <clear /> <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" /> <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" /> </providers> </roleManager> <pages> <namespaces> <add namespace="System.Web.Helpers" /> <add namespace="System.Web.Mvc" /> <add namespace="System.Web.Mvc.Ajax" /> <add namespace="System.Web.Mvc.Html" /> <add namespace="System.Web.Routing" /> <add namespace="System.Web.WebPages" /> </namespaces> </pages> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true" /> </system.webServer> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0" /> <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0" /> </dependentAssembly> </assemblyBinding> <legacyHMACWarning enabled="0" /> </runtime> <uri>  <idn enabled="All" /> <iriParsing enabled="true" /> </uri> <system.net> <defaultProxy enabled="true" /> <settings>   </settings> </system.net> <dotNetOpenAuth>   <openid> <relyingParty> <security requireSsl="false" /> <behaviors>  <add type="DotNetOpenAuth.OpenId.Behaviors.AXFetchAsSregTransform, DotNetOpenAuth" /> </behaviors> </relyingParty> </openid> <messaging> <untrustedWebRequest> <whitelistHosts>   </whitelistHosts> </untrustedWebRequest> </messaging>  <reporting enabled="true" /> </dotNetOpenAuth> </configuration>

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注册：

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

但我建议您使用openid-selector库生成登录表单。

当我试图让NerdDinner OpenID为MVC3 / razor工作时，我遇到了这个问题。对我有用的解决方案是：

在您的解决方案中创建此类:(这在NerdDinner构建中找到 - http://nerddinner.codeplex.com/SourceControl/changeset/view/55257#1328982（感谢JasonHaley）由于某种原因，此文件不在NerdDinner MVC3 / Razor的最新版本中

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DotNetOpenAuth;
namespace <Your App>.Services
{
    public class EmbeddedResourceUrlService : IEmbeddedResourceRetrieval
    {

        private static string pathFormat = "{0}/{1}/Resource/GetWebResourceUrl?assemblyName={2}&typeName={3}&resourceName={‌4}";
        //private static string pathFormat = "{0}/Resource/GetWebResourceUrl";

        public Uri GetWebResourceUrl(Type someTypeInResourceAssembly, string manifestResourceName)
        {
            if (manifestResourceName.Contains("http"))
            {
                return new Uri(manifestResourceName);
            }
            else
            {
                var assembly = someTypeInResourceAssembly.Assembly;

                // HACK
                string completeUrl = HttpContext.Current.Request.Url.ToString();
                string host = completeUrl.Substring(0,
                    completeUrl.IndexOf(HttpContext.Current.Request.Url.AbsolutePath));

                var path = string.Format(pathFormat,
                            host,
                            HttpContext.Current.Request.ApplicationPath.Substring(1),
                            HttpUtility.UrlEncode(assembly.FullName),
                            HttpUtility.UrlEncode(someTypeInResourceAssembly.ToString()),
                            HttpUtility.UrlEncode(manifestResourceName));

                return new Uri(path);
            }
        }
    }
}

然后在您的web.config中添加以下行：

<webResourceUrlProvider type="<Your App>.Services.EmbeddedResourceUrlService, <Your App>" />

只需输入DotNetOpenAuth部分

您还需要设置此路线：（Html.OpenIdSelectorScripts helper method throwing NullReferenceException）

    routes.MapRoute(
        "OpenIdDiscover",
        "Auth/Discover"
    );

使用Razor视图抛出有关DotNetOpenAuth.IEmbeddedResourceRetrieval的InvalidOperationException
