NancyFx 2.0的開源框架的使用-Authentication

新建一個空的項目

新建好了空的項目以後，接著通過NuGet安裝一下三個包

• Nancy
• Nancy.Hosting.Aspnet
• Nancy.ViewEnglines.Razor

然後在項目中添加Models，Module，Views三個文件夾，併在Models中添加UserModel類

        public string  Username { get; set; }
        public UserModel(string username)
        {
            this.Username = username;
        }

然後往Module文件夾裡面添加MainModule類

 Get("/", Lexan => { return View["index.cshtml"]; });
            Get("/login", Lexan => { return View["login.cshtml",this.Request.Query.returnUrl]; });

再繼續添加SecureModule類，AnotherVerySecureModule類

        public SecureModule():base("/secure")
        {
            this.RequiresAuthentication();
            Get("/",Lexan=>
            {
                var model = new UserModel(this.Context.CurrentUser.Identity.Name);
                return View["secure.cshtml",model];
            });
        }

 public AnotherVerySecureModule():base("/superSecure")
        {
            this.RequiresClaims(Lexan=>Lexan.Type==ClaimTypes.Role&&Lexan.Value=="SuperSecure");
            Get("/",Lexan=> 
            {
                var model = new UserModel(this.Context.CurrentUser.Identity.Name);
                return View["superSecure.cshtml",model];
            });
        }

根目錄添加AuthenticationBootstrapper類

        protected override void ApplicationStartup(TinyIoCContainer container, IPipelines pipelines)
        {
            base.ApplicationStartup(container, pipelines);
            pipelines.BeforeRequest += ctx =>
              {
                  var username = ctx.Request.Query.username;
                  if (username.HasValue)
                  {
                      ctx.CurrentUser = new ClaimsPrincipal(new ClaimsIdentity(BuildClaims(username), "querystring"));
                  }
                  return null;
              };
            pipelines.AfterRequest += ctx =>
              {
                  if (ctx.Response.StatusCode==HttpStatusCode.Unauthorized)
                  {
                      ctx.Response = new RedirectResponse("/login?retutnUrl="+ Uri.EscapeDataString(ctx.Request.Path));
                  }
              };
        }
        private static IEnumerable<Claim> BuildClaims(string userName)
        {
            var claims = new List<Claim>();
            if (String.Equals(userName,"Lexan",StringComparison.OrdinalIgnoreCase))
            {
                claims.Add(new Claim(ClaimTypes.Role,"SuperSecure"));
            }
            return claims;
        }

繼續在Views里添加視圖index，login，secure，superSecure

再然後修改一下Web.config如下圖

運行如下圖
