简介

Nancy 是一个轻量级的，简单粗暴的framework用来构建基于HTTP的各种服务，兼容.Net和Mono。它的返回值也是多种多样的，适应各种不同的情况。包括Response.AsFile()、Response.AsRedirect()、 Response.AsImage()、 Response.AsJson()、Response.AsText()、 Response.AsXml()等

一：string

Get["/get"] = parameters =>{   return "Nancy";}

二：返回视图，像MVC一样，需要有Views/Home/index.html网页才能成功

Get["/get"] = parameters => { return View["/home/index.html"]; }

 

 

三：Response

Post["/GetMore"] = p =>{  Product pd = new Product();  pd.Id = 10;  pd.Address = "北京超越";  pd.Name = "苹果手机";  pd.Price = 1000; return Response.AsJson(pd);  return Response.AsXml(pd); }

四：Response返回值源码

public static implicit operator Response(HttpStatusCode statusCode)    {        return new Response { StatusCode = statusCode };    }    public static implicit operator Response(int statusCode)    {        return new Response { StatusCode = (HttpStatusCode)statusCode };    }    public static implicit operator Response(string contents)    {        return new Response { Contents = contents, ContentType = "text/html", StatusCode = HttpStatusCode.OK };    }    public static implicit operator string(Response response)    {        return response.Contents;    }

 五：Contents源码

public static class FormatterExtensions{    public static Response AsJson
     
      (this IResponseFormatter formatter, TModel model)    {        return new JsonResponse
      
       (model);    }    public static Response AsXml
       
        (this IResponseFormatter formatter, TModel model)    {        return new XmlResponse
        
         (model);    }    public static Response Image(this IResponseFormatter formatter, string imagePath)    {        return new ImageResponse(imagePath);    }}
        
       
      
     

 

public static Action
     
       Static(this IViewEngine engine, string virtualPath)    {        return stream => {            var path = HostingEnvironment.MapPath(virtualPath);            using (var reader = new StreamReader(path))            {                using(var writer = new StreamWriter(stream))                {                    writer.Write(reader.ReadToEnd());                    writer.Flush();                }            }        };    }，
     

六、自定义返回值

Get["/get"] = parameters =>            {                var path = AppDomain.CurrentDomain.BaseDirectory + "/Views/home/index.html";                Response response = new Response();                response.ContentType = "text/html";                response.Contents = stream =>                {                    using (var reader = new StreamReader(path))                    {                        using (var writer = new StreamWriter(stream))                        {                            writer.Write(reader.ReadToEnd());                            writer.Flush();                        }                    }                };                return response;            };
