Get Nancy Request Information

Question

I just started looking at Nancy and I was using a Sinatra Video (what Nancy is based on) from Tekpub, to see what it could do. One of the things demonstrated in the video was outputting the request information back to the browser (request method, request path, etc...). When I use ASP.Net Web Forms I can get to that information in the Request object, but I didn't see anything in the documentation that showed me how to do this in Nancy. I know there is a Headers field in the Nancy.Request object, but it didn't give me all the information I was looking for. Below is the original Sinatra Code that I want to convert to C# and Nancy:

class HelloWorld
     def call(env)
          out = ""
          env.keys.each {|key| out+="#{key}=#{env[key]}"}
          ["200",{"Content-Type" => "text/plain"}, out]
     end
 end

 run HelloWorld.new

Solution

You mean something like this?

Get["/test"] = _ =>
{
    var responseThing = new
    {
        this.Request.Headers,
        this.Request.Query,
        this.Request.Form,
        this.Request.Session,
        this.Request.Method,
        this.Request.Url,
        this.Request.Path
    };

    return Response.AsJson(responseThing);
};

This would give you an output like:

{
   "Form":{

   },
   "Headers":[
      {
         "Key":"Cache-Control",
         "Value":[
            "max-age=0"
         ]
      },
      {
         "Key":"Connection",
         "Value":[
            "keep-alive"
         ]
      },
      {
         "Key":"Accept",
         "Value":[
            "text/html;q=1",
            "application/xhtml+xml;q=1",
            "application/xml;q=0.9",
            "*/*;q=0.8"
         ]
      },
      {
         "Key":"Accept-Encoding",
         "Value":[
            "gzip,deflate,sdch"
         ]
      },
      {
         "Key":"Accept-Language",
         "Value":[
            "en-US,en;q=0.8"
         ]
      },
      {
         "Key":"Host",
         "Value":[
            "localhost:2234"
         ]
      },
      {
         "Key":"User-Agent",
         "Value":[
            "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.29 Safari/537.36"
         ]
      }
   ],
   "Method":"GET",
   "Path":"/test",
   "Query":{
      "23423":"fweew"
   },
   "Session":[

   ],
   "Url":{
      "BasePath":null,
      "Fragment":"",
      "HostName":"localhost:2234",
      "IsSecure":false,
      "Path":"/test",
      "Port":null,
      "Query":"23423=fweew",
      "Scheme":"http",
      "SiteBase":"http://localhost:2234"
   }
}
