Question

我正在使用MVCReportViewer来显示SSRS 2012报告。我通过Nuget安装，它适用于初始加载。但是，如果单击视图，无论是否更改参数，加载对话框都不会关闭，报表永远不会呈现。检查请求我发现XHR请求失败。它实际上显示了状态代码200，但检查响应会产生以下结果......

报表查看器Web控件HTTP处理程序尚未在应用程序的web.config文件中注册。添加到web.config文件的system.web / httpHandlers部分，或添加到Internet Information Services 7或更高版本的system.webServer / handlers部分。

以下是我的httphandler部分......

  <system.web>
    <httpHandlers>
      <!-- Required by Microsoft ReportViewer control -->
      <add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
    </httpHandlers>
  </system.web>

  <system.webServer>
    <handlers>
      <!-- Required by Microsoft ReportViewer control -->
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
      <remove name="ReportViewerWebControlHandler" />
      <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
  <system.webServer>

我无法弄清楚它在初始加载时是如何工作的，但在以下请求中失败了。这在VS 2012开发服务器上本地工作，但在IIS7上失败。

感谢任何帮助。

MVCReportViewer后续请求错误
