对于我的MVC 4网站，我使用ImageResizer进行服务器端图像大小调整。我发现这是一个很棒的插件，但我遇到了一个小问题。
我通过NuGet工具安装了ImageResizer并自定义了web.config文件，以使用SqlReader插件从我的SQLDatabase中检索图像blob。我面临的问题是，当我在URL中包含查询字符串时，图像被很好地检索，但是当它只是图像名称和扩展名时，我从IIS收到404错误。
这会返回一张图片： 〜/内容/图像/ ef2dfaa8-5eb8-e411-827a-543530365cbe.jpg？W = 100
这将返回404错误，其详细信息如下： 〜/内容/图像/ ef2dfaa8-5eb8-e411-827a-543530365cbe.jpg
详细错误信息： 模块IIS Web核心 通知MapRequestHandler 处理程序StaticFile 错误代码0x80070002 请求的网址https://localhost:44300/content/images/ef2dfaa8-5eb8-e411-827a-543530365cbe.jpg 物理路径E：\ Work \ website \ website_site \ website \ website \ content \ images \ ef2dfaa8-5eb8-e411-827a-543530365cbe.jpg 登录方法匿名 登录用户匿名 请求跟踪目录C：\ Users \Gabriël\ Documents \ IISExpress \ TraceLogFiles \ WEBSITE（6）
我已经研究过这个问题，我唯一合乎逻辑的结论是它与注册虚拟路径或访问权限有关。我不知道从哪里开始。任何人都可以帮助引导我朝着正确的方向解决这个问题吗？
web.config的配置部分如下所示
<resizer>
<plugins>
<add name="MvcRoutingShim" />
<add name="SqlReader"
prefix="~/content/images/"
connectionString="ConnectionStringByName"
idType="UniqueIdentifier"
blobQuery="SELECT FileData From ContentFiles WHERE Id=@id"
modifiedQuery="SELECT UploadTime,UploadTime From ContentFiles WHERE Id=@id"
existsQuery="SELECT COUNT(Id) From ContentFiles WHERE Id=@id"
requireImageExtension="false"
cacheUnmodifiedFiles="false"
extensionPartOfId="false"
checkForModifiedFiles="false"
vpp="true"
untrustedData="false" />
</plugins>
我在VS2012和IIS8.5上使用MVC4进行本地调试。

The following plugin assemblies are loaded but do not seem to be in use. You should remove them (and especially their dependencies (unless used elsewhere)) from the /bin folder to improve application load times:
ImageResizer.Plugins.DiskCache Assembly: 3.4.3.103 File: 3.4.3.103 Info: 3-4-3 Commit: bf92fd7
Reference list of plugin dependencies - so you know what additional dlls to remove when removing a plugin. (may not be up-to-date, see plugin docs):
The FreeImage plugin has the following dependencies: FreeImage.dll and FreeImageNET.dll
The Logging plugin depends on: NLog.dll
The AdvancedFilters, RedEye, and WhitespaceTrimmer plugins depend on: AForge.dll, AForge.Math.dll, and AForge.Imaging.dll
The PsdReader and PsdComposer plugins depend on: PsdFile.dll
The S3Reader plugin depends on: LitS3.dll
The BatchZipper plugin depends on: Ionic.Zip.Reduced.dll
The PdfRenderer plugin depends on gsdll32.dll or gdsll32.dll
The RedEye plugin depends on several dozen files... see the plugin docs.

更改我的web.config文件条目
cacheUnmodifiedFiles="true"
似乎可以解决问题。

在.NET 4.0中，StaticFileHandlers的行为已发生变化;它们不再处理可通过VirtualPathProvider访问的请求。
恢复旧行为的解决方法 - 编辑web.config：
<system.webServer>
<handlers>
<add name="StaticGifImages" path="*.gif" verb="*" type="System.Web.StaticFileHandler" />
<add name="StaticPngImages" path="*.png" verb="*" type="System.Web.StaticFileHandler" />
<add name="StaticJpgImages" path="*.jpg" verb="*" type="System.Web.StaticFileHandler" />
</handlers>
</system.webServer>
