找不到CrystalImageHandler.aspx

Question

我在MVC3应用程序中的普通ASP.NET aspx页面上使用Crystal报表查看器.在控制器操作中,我只是重定向到aspx页面,报告显示正常.但问题在于动态图像.我找到了最简单的解决方案,将图像路径作为报表参数传递,并将此参数设置为图像源.在Visual Studio预览中,这工作正常但在执行时我在页面上看到此错误.

"NetworkError:404 Not Found - server /ReportWebForms/CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_4fbcb73a-e001-4365-84fc-164788dd1605.png"

所以我假设,以前没有水晶报告的经验,问题出在CrystalImageHandler.aspx中.我在Web.config中有这些条目:

  <httpHandlers><add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/></httpHandlers></system.web>
  <handlers><add name="CrystalImageHandler.aspx_GET" verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" preCondition="integratedMode"/></handlers></system.webServer>

这是MVC类型的问题吗？有人可以帮忙吗？

谢谢

Answer 1

我有同样的问题,但幸运的是我有一些Crystal Reports的经验.

您只需要更改Web.config,因为"path"属性设置为site root.如果您在浏览器中打开URL并从中删除ReportWebForms,它将起作用.

实际上我刚添加了2行配置:

<system.web>
    <httpHandlers>
      <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" />
      <!-- Added -->
      <add verb="GET" path="Reports/CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" />
      <add verb="GET,HEAD" path="asset.axd" validate="false" type="Telerik.Web.Mvc.WebAssetHttpHandler, Telerik.Web.Mvc" />
    </httpHandlers>
</system.web>

<system.webServer>
    <handlers>
      <add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
      <add name="CrystalImageHandler.aspx_GET" verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" preCondition="integratedMode" />
      <!-- Added -->
      <add name="CrystalImageHandler.aspx_GETR" verb="GET" path="Reports/CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" preCondition="integratedMode" />
      <remove name="asset" />
      <add name="asset" preCondition="integratedMode" verb="GET,HEAD" path="asset.axd" type="Telerik.Web.Mvc.WebAssetHttpHandler, Telerik.Web.Mvc" />
    </handlers>
</system.webServer>

最后,您必须为MVC应用程序添加一个忽略规则:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
// Here is added new ignore rule
routes.IgnoreRoute("Reports/{resource}.aspx/{*pathInfo}");

在我的例子中,我有一个名为Reports的文件夹,其中放置了.aspx文件.我想你应该在你的情况下将其更改为ReportWebForms.

在我的情况下,我只需要忽略MVC的路由.要添加到@Hovhannes解决方案.您应该将此规则添加到Routeconfig.cs

routes.IgnoreRoute("{*allaspx}", new { allaspx = @".*(CrystalImageHandler).*" });

使用此代码作为 CrystalImageHandler.aspx：

<%@ Page Language="C#" AutoEventWireup="true" %>

<script runat="server" language="c#" >
    protected void Page_Load(object sender, EventArgs e)
    {
        CrystalDecisions.Web.CrystalImageHandler handler = new CrystalDecisions.Web.CrystalImageHandler();
        handler.ProcessRequest(this.Context);            
    }
</script>
