c# - ServiceStack: Serving Static files from a directory when present? -

i in process of converting stand-alone home grown web server use servicestack serving pages , resources.

i see question

serving static file servicestack

that easy serve single static file service stack.

in home grown implementation, after checking see if url matches particular handler (equivalent servicestack routes), default handler checks static file in httpdata directory serve matching url.

if file not exist, generates 404 error.

what best pattern use servicestack serve files file system if no other service matched? note using in standalone mode without iis.

these files can html, png, js, , small handful of other content types.

note: see servicestack.razor package may assist requiredments, cannot find documentation on it. put in separate question that.

edit: found reference in question

create route root path, '/', servicestack

indicating

register iapphost.catchallhandlers - gets called un-matched requests.

so far, have not found documentation or example on how to registration. note: running stand-alone, needs done in c#, not xml.

after research, have found following seems effective.

configuration

in apphost constructor:

                catchallhandlers.add(                     (httpmethod, pathinfo, filepath) =>                          tims.support.staticfilehandler.factory(                             params.instance.httpdatadir,                              "/",                              pathinfo                     )                 ); 

the factory

checks existance of file, , returns appropriate handler, or returns null if not handling file (because not exist). important other urls (such /metadata continue work.

handler

the core method of actual handler simple. overriding processrequest , returnign bytes of file appropriate resource type, job done. version, simplicity, not include date handling caching purposes.

sample code

public class staticfilehandler : endpointhandlerbase {     protected static readonly dictionary<string, string> extensioncontenttype;      protected fileinfo fi;      static staticfilehandler()     {         extensioncontenttype = new dictionary<string, string>       (stringcomparer.invariantcultureignorecase)          {             { ".text", "text/plain" },             { ".js", "text/javascript" },             { ".css", "text/css" },             { ".html", "text/html" },             { ".htm", "text/html" },             { ".png", "image/png" },             { ".ico", "image/x-icon" },             { ".gif", "image/gif" },             { ".bmp", "image/bmp" },             { ".jpg", "image/jpeg" }         };     }      public string basedirectory { protected set; get; }     public string prefix { protected set; get; }      public staticfilehandler(string basedirectory, string prefix)      {                     basedirectory = basedirectory;         prefix = prefix;     }      private staticfilehandler(fileinfo fi)     {         this.fi = fi;     }      public static staticfilehandler factory(string basedirectory, string prefix, string pathinfo)     {         if (!pathinfo.startswith(prefix, stringcomparison.invariantcultureignorecase))         {             return null;         }          var fn = basedirectory + "/" + pathinfo.after(prefix.length);          var fi = new system.io.fileinfo(fn);          if (!fi.exists)         {             return null;         }         return new staticfilehandler(fi);     }         public override void processrequest(ihttprequest httpreq, ihttpresponse httpres, string operationname)     {         using (var source = new system.io.filestream(fi.fullname, system.io.filemode.open))         {             var bytes = source.readallbytes();             httpres.outputstream.write(bytes, 0, bytes.length);         }          // timestamp = fi.lastwritetime;                                  httpres.addheader("date", datetime.now.tostring("r"));         httpres.addheader("content-type", extensioncontenttype.safeget(fi.extension) ?? "text/plain");                            }      public override object createrequest(ihttprequest request, string operationname)     {         return null;     }      public override object getresponse(ihttprequest httpreq, ihttpresponse httpres, object request)     {         return null;     } }
