MVC4 routing parameter with point filename suffix causes an error

Error description

Recently in the study of Office Online previews, the use of Mvc4 Apicontroller requires that the parameter is a file name, such as Test.docx causing the error "The specified directory or file does not exist on the WEB server",

The requested path, such as: Api/wopi/files/test.docx?access_token=access_token. As follows:

Route configuration in Project:

 Public Static classWebapiconfig { Public Static voidRegister (httpconfiguration config) {//Office Web AppsCONFIG. Routes.maphttproute (Name:"Contents", Routetemplate:"wopi/files/{name}/contents", defaults:New{controller ="Files", action ="GetFile" }             ); Config. Routes.maphttproute (Name:"FileInfo", Routetemplate:"Api/wopi/files/{name}", defaults:New{controller ="Files", action ="GetFileInfo", name =routeparameter.optional}); Config. Routes.maphttproute (Name:"Defaultapi", Routetemplate:"Api/{controller}/{id}", defaults:New{id =routeparameter.optional}); //uncomment the following line of code to enable query support for operations that have a IQueryable or iqueryable<t> return type. //to avoid handling unexpected queries or malicious queries, use the validation settings on Queryableattribute to validate incoming queries. //For more information, please visithttp://go.microsoft.com/fwlink/?LinkId=279712. //CONFIG. Enablequerysupport ();        }    }

Controller method, note that this is apicontroller.

 Public classFilescontroller:apicontroller { PublicCheckfileinfo GetFileInfo (stringNamestringAccess_token) {            string_access_token =Access_token; varFile = Hostingenvironment.mappath ("~/app_data/"+ name);//get the name file from the hard diskFileInfo Info=NewFileInfo (file); if(!info.

Solutions

Add node <modules runallmanagedmodulesforallrequests= "true"/> under node system.webserver node in Webconfig; and set the IIS mode to Integrated mode (iis-> application pool, find your website right-click "Advanced Settings", set into integrated mode).

The system.webserver setting takes effect only if IIS is in Integrated mode.

<system.webServer> "extensionlessurlhandler-integrated-4.0"/> <remove name="Optionsverbhandler"/> <remove name="Traceverbhandler"/> <add name="extensionlessurlhandler-integrated-4.0"Path="*."verb="*"type="System.Web.Handlers.TransferRequestHandler"Precondition="integratedmode,runtimeversionv4.0"/> "true"/> </system.webServer>
