Crystal Reports 图像和 ASP.Net MVC [英] Crystal Reports Images and ASP.Net MVC

问题描述

在使用 CrystalImageHandler.aspx 的图表和图像时，我遇到了 Crystal Reports 的问题.图像无法显示，我怀疑这是由于 MVC 路由问题.

I am having trouble with Crystal Reports when using charts and images which use CrystalImageHandler.aspx. The image cannot display and I suspect this is due to a problem with MVC routing.

path图片路径类似这样:

The path image path is similar to this:

src="/CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_a8301f51-26de-4869-be9f-c3c9ad9cc85e.png"

src="/CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_a8301f51-26de-4869-be9f-c3c9ad9cc85e.png"

与此类似的网址:

localhost:01234/ViewCrystalReports.aspx?id=50

localhost:01234/ViewCrystalReports.aspx?id=50

可能无法找到该图像，因为它正在一个不存在的目录中查找.如何更改 CrystalImageHandler.aspx 所在的路径?我认为如果我从根目录引用问题将得到解决，但我在 Web.Config 中所做的任何更改都无法正常工作.

The image cannot be found prumably because it's looking in a non-existant directory. How can I change the path CrystalImageHandler.aspx is located at? I think if I were to reference from the root the problem would be solved but anything I change in Web.Config fails to work.

我应该提到这是在传统的 aspx 页面上，而不是视图等

I should mention this is on a conventional aspx page, not a view etc

推荐答案

想通了.路由干扰了正在生成的 CrystalImageHandler.aspx 链接.Global.aspx 有以下行告诉路由引擎忽略资源文件:

Figured it out. The routing was interfering with the CrystalImageHandler.aspx link that was being generated. Global.aspx has the following line to tell the routing engine to ignore resource files:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

但这不是传统的资源文件，出于某种原因它是一个 aspx 文件(有人知道为什么吗?)

but this isn't a conventional resource file, it's an aspx file for some reason (anyone know why?)

添加此修复它:

  routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
