这次自己实现了类似jQuery中ajax调用的方法，并且针对RESTFul进行了改造和集成，实现的A2D AJAX接口如下： 

$.ajax.RESTFulGetCollection("/api/Users", function (data) { alert(data[5].FirstName); });$.ajax.RESTFulGetOne("/api/Users/1", function (data) { alert(data.UserID); });$.ajax.RESTFulDelete("/api/Users/1", function (data) { alert("deleted"); });$.ajax.RESTFulPost("/api/Users", { UserID: 0, FirstName: "aa", LastName: "bbb"}, function (data) { alert("added"); });$.ajax.RESTFulPut("/api/Users/1", { UserID: 0, FirstName: "aa", LastName: "bbb"}, function (data) { alert(data); });

 

我们再深入点，要是别人恶意访问Delete的url呢？比如CSRF攻击。普通webform或者普通MVC方式可以比较方便的阻止攻击, 方法参考的A8章节

答案：使用http header来传递token。步骤如下（以A2D与ASP.NET WEBAPI配合为例）：

@functions{        public string TokenHeaderValue()        {            string cookieToken, formToken;            AntiForgery.GetTokens(null, out cookieToken, out formToken);            return cookieToken + ":" + formToken;                        }    }    $.ajax.Config.CSRFToken="@TokenHeaderValue()";    //把生成的token赋给A2D的ajax    $.ajax.RESTFulGetCollection("/api/Users", function (data) { alert(data[5].FirstName); });    $.ajax.RESTFulGetOne("/api/Users/1", function (data) { alert(data.UserID); });    $.ajax.RESTFulDelete("/api/Users/1", function (data) { alert("deleted"); });    $.ajax.RESTFulPost("/api/Users", { UserID: 0, FirstName: "aa", LastName: "bbb"}, function (data) { alert("added"); });    $.ajax.RESTFulPut("/api/Users/1", { UserID: 0, FirstName: "aa", LastName: "bbb"}, function (data) { alert(data); });

 

然后编写webapi的handler：

public class CSRFHandler : DelegatingHandler    {        protected override System.Threading.Tasks.Task
     
       SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken)        {            if (request.Method == HttpMethod.Post ||                request.Method == HttpMethod.Put ||                request.Method == HttpMethod.Delete)//这里csrf只针对这3种请求才会验证            {                ValidateRequestHeader(request);            }            return base.SendAsync(request, cancellationToken);        }        private void ValidateRequestHeader(HttpRequestMessage request)        {            string cookieToken = "";            string formToken = "";            IEnumerable
      
        tokenHeaders;            if (request.Headers.TryGetValues("A2D-CSRFToken", out tokenHeaders)) //这个header值要和A2D框架中的一致            {                string[] tokens = tokenHeaders.First().Split(':');                if (tokens.Length == 2)                {                    cookieToken = tokens[0].Trim();                    formToken = tokens[1].Trim();                }            }            AntiForgery.Validate(cookieToken, formToken);        }    }
      
     

 

最后在WebApiConfig中注册这个handler

public static class WebApiConfig    {        public static void Register(HttpConfiguration config)        {            config.MessageHandlers.Add(new CSRFHandler());            config.Routes.MapHttpRoute(                name: "DefaultApi",                routeTemplate: "api/{controller}/{id}",                defaults: new { id = RouteParameter.Optional }            );        }    }

 

好了，都搞定了。
