NancyFx 2.0的开源框架的使用-ModelBinding(实现绑定)

NancyFx框架中使用绑定模型

新建一个空的Web程序

然后安装Nuget库里面的包

Nancy
Nancy.Hosting.Aspnet
Nancy.ViewEnglines.Spark

并在Web应用程序里面添加Models，Module，Views三个文件夹

继续往Models文件夹里面添加Database，ModelBinders

然后往Models文件夹里面添加Customer类

        public int Id { get; set; }

        public string Name { get; set; }

        public DateTime RenewalDate { get; set; }

继续往Models文件夹里面添加Event类

        public int Id { get; set; }

        public string Title { get; set; }

        public string Location { get; set; }

        public IEnumerable<int> Venues { get; set; }

        public DateTime Time { get; set; }

        public Event()

        {

            this.Title = "Lexan";

            this.Location = "Lexan";

            this.Time = DateTime.Now;

        }

继续往Models文件夹里面添加User类

        public string Name { get; set; }

        public string Address { get; set; }

然后往Database文件夹里面添加DB类

        public static List<Event> Events { get; private set; }

        public static List<Customer> Customer { get; private set; }

        static DB()

        {

            Events = new List<Models.Event>();

            Customer = new List<Models.Customer>();

        }

然后往ModelBinders文件夹里面添加CustomerModelBinder类

//是否可以绑定到给定的模型类型

        public bool CanBind(Type modelType)

        {

            return modelType == typeof(Customer);

        }

        //绑定到给定的模型类型

        public object Bind(NancyContext context,Type modelType, object instance,BindingConfig configuration,params string[] blackList)

        {

            var customer = (instance as Customer) ?? new Customer();

            customer.Name = customer.Name ?? context.Request.Form["Name"];

            customer.RenewalDate = customer.RenewalDate == default(DateTime) ? context.Request.Form["RenewalDate"] : customer.RenewalDate;

            return customer;

        }

然后往Module里添加MainModule类

 public MainModule()

        {

            Get("/", Lexan =>

            {

                return "<a href='/events'>Events (默认模型绑定)</a><br><a href='/customers'>Customers (自定义模型绑定)</a><br><a href='/bindjson'>Users (JSON)</a></a><br><a href='/bindxml'>Users (XML)</a><br>";

            });

        }

然后往Module里添加CustomersModule类

 public CustomersModule() : base("/customers")

        {

            Get("/",Lexan=>

            {

                var model = DB.Customer.OrderBy(e=>e.RenewalDate).ToArray();

                return View["Customers",model];

            });

            Post("/",Lexan=>

            {

                Customer model = this.Bind();

                var models = this.Bind<Customer>();

                DB.Customer.Add(model);

                DB.Customer.Add(models);

                return this.Response.AsRedirect("/Customers");

            });

        }

然后往Module里添加EventsModule类

 public EventsModule():base("/events")

        {

            Get("/",Lexan=>

            {

                var model = DB.Events.OrderBy(x=>x.Time).ToArray();

                return View["Events",model];

            });

            Post("/",Lexan=>

            {

                Event model = this.Bind();

                var models = this.Bind<Event>("Location");

                DB.Events.Add(model);

                DB.Events.Add(models);

                return this.Response.AsRedirect("/Events");

            });

        }

然后往Module里添加JsonModule类

  public JsonModule()

        {

            Get("/bindjson",Lexan=>

            {

                return View["PostJson"];

            });

            Post("/bindjson",Lexan=>

            {

                User model = this.Bind();

                var sb = new StringBuilder();

                sb.AppendLine("绑定模型:");

                sb.Append("类型:");

                sb.AppendLine(model.GetType().FullName);

                sb.Append("名字:");

                sb.AppendLine(model.Name);

                sb.Append("地址:");

                sb.AppendLine(model.Address);

                return sb.ToString();

            });

        }

然后往Module里添加XmlModule类

 public XmlModule()

        {

            Get("/bindxml",Lexan=>

            {

                return View["PostXml"];

            });

            Post("/bindxml",Lexan=>

            {

                var model = this.Bind<User>(x=>x.Name);

                var sb = new StringBuilder();

                sb.AppendLine("绑定模型:");

                sb.Append("类型:");

                sb.AppendLine(model.GetType().FullName);

                sb.Append("名字:(这将是空的, 因为它被忽略)");

                sb.AppendLine(model.Name);

                sb.Append("地址:");

                sb.AppendLine(model.Address);

                return sb.ToString();

            });

        }

然后往根目录里面添加Bootstrapper类

然后往Views文件夹里面添加Customers.txt文件

然后把Customers.txt改成Customers.spark

添加如下内容

<viewdata model="ModelBindingDemo.Models.Customer[]"/>

<html>

  <head>

    <title>客户</title>

  </head>

  <body>

    <h1>客户</h1>

    <p>客户被添加了两次, 一个使用动态活页夹适配器, 另一个使用通用的.</p>

    <p>当前客户:</p>

    <ul>

      <li each="var v in Model">

        <a href="customer/${v.Id}"> ${v.Name} - ${v.RenewalDate.ToShortDateString()} </a>

      </li>

    </ul>

    <h2>添加另一个</h2>

    <form method="POST" action="/customers">

      <label for="Name">名字</label>

      <input type="text" name="Name" />

      <label for="Location">更新日期</label>

      <input type="text" name="RenewalDate" />

      <input type="submit"/>

    </form>

  </body>

</html>

同样的做法添加Event.txt添加成功后改成Event.spark

并添加如下内容

<viewdata model="ModelBindingDemo.Models.Event[]"/>

<html>

  <head>

    <title>事件</title>

  </head>

  <body>

    <h1>事件</h1>

    <p>事件被添加两次, 一个使用动态活页夹适配器, 另一个使用通用的.</p>

    <p>第二个有 ' 位置 ' 标记为黑名单, 因此应该显示为 ' 默认 '</p>

    <p>当前事件:</p>

    <ul>

      <li each="var v in Model">

        <a href="event/${v.Id}"> ${v.Title} - ${v.Location} </a> ${v.Time}

      </li>

    </ul>

    <h2>Add another</h2>

    <form method="POST" action="/events">

      <label for="Name">标题</label>

      <input type="text" name="Title" />

      <label for="Location">位置</label>

      <input type="text" name="Location" />

      <input type="checkbox" name="Venues" value="">地点 </input>

      <input type="checkbox" name="Venues" value="">地点 </input>

      <input type="checkbox" name="Venues" value="">地点 </input>

      <input type="checkbox" name="Venues" value="">地点 </input>

      <label for="EventDate">时间</label>

      <input type="text" name="Time" value="${System.DateTime.Now}"/>

      <input type="submit"/>

    </form>

  </body>

</html>

然后继续再Views文件夹里面添加PostJson.html

<html>

<head>

    <title>JSON Post Test</title>

    <script type="text/javascript">

         $(function () {

             var dat = "{\"Name\":\"This is the name\", \"Address\":\"This is the address\"}";

             alert("将以下数据粘贴到 /bindjson:\n\n" + dat);

             $.ajax({

                 type: "POST",

                 url: "/bindjson",

                 contentType: "application/json",

                 data: dat,

                 success: function (data) {

                     alert("Response:\n" + data);

                 }

             });

         });

    </script>

</head>

<body>

    JSON Post

</body>

</html>

继续添加PostXml.html页面

<html>

<head>

    <title>XML Post Test</title>

    <script type="text/javascript">

         $(function () {

             var dat = "<User><Name>这是名字</Name><Address>这是地址</Address></User>";

             alert("将以下数据粘贴到 /bindxml:\n\n" + dat);

             $.ajax({

                 type: "POST",

                 url: "/bindxml",

                 contentType: "application/xml",

                 data: dat,

                 success: function (data) {

                     alert("Response:\n" + data);

                 }

             });

         });

    </script>

</head>

<body>

    XML Post

</body>

</html>

最后修改Web.config配置文件

    <httpRuntime targetFramework="4.5.2"/>

      <httpHandlers>

      <add verb="*" type="Nancy.Hosting.Aspnet.NancyHttpRequestHandler" path="*" />

    </httpHandlers>

  </system.web>

    <system.webServer>

    <modules runAllManagedModulesForAllRequests="true" />

    <validation validateIntegratedModeConfiguration="false" />

    <handlers>

      <add name="Nancy" verb="*" type="Nancy.Hosting.Aspnet.NancyHttpRequestHandler" path="*" />

    </handlers>

  </system.webServer>

现在我们看看运行的结果

到这里就结束了，感谢你的欣赏，这篇也算介绍完了NancyFx2.0版本的基本使用，后期看看如果有空的话会继续更新，我们不见不散，哈哈哈！
