将JSON对象发布到WCF服务对象始终为空

Question

我在'post'.am获取用户对象始终为空时遇到问题..我在我的智慧结束并且一直在研究这些好几天，所以如果有人有任何想法，请帮帮我！在此先感谢

我的Jquery看起来像WCF这样

$(document).ready(function() { 
     $("#register").click(function (e) { 
      e.preventDefault(); //stop the submit event for the submit button 
      var Name = $("#register_username").val(); 
      var Email = $("#register_email").val(); 
      var Password = $("#register_password").val(); 
      var Contact = $("#register_contactNumber").val(); 
      var Adress = "Seteelte Town"; 
      var chkUserType = document.getElementById("identity_type_2").checked; 
      var userinfo = { "request": { "Action": { "Address": Adress, "Children": [], "CityId": 0, "Email": Email, "HomeUser": chkUserType, "ImagePath": "", "IpAdress": "", "IsActive": false, "LastLogin": "", "Name": Name, "Password": Password, "PhoneNumber": Contact, "ProfileHit": 0, "ShowEmail": false, "ShowPhoneNumber": false, "SubscribeNews": false, "UserID": 0}} }; 

      alert("Input: " + JSON.stringify(userinfo)); 
      $.ajax({ 
       type: "POST", 
       url: '/Services/Membership.svc/AccountAdd', 
       data: JSON.stringify(userinfo), 
       dataType: 'json', 
       contentType: "application/json; charset=utf-8", 
       success: function (data) { 
        alert(data.Result); 
       }, 
       error: onError 
      }); 
     }); 
    }); 

我的C＃代码是

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    public class Membership : IMembership 
    { 

     public SMProcessResponse<bool> AccountAdd(SMProcess<User> request) 
     { 
      return new SMProcessResponse<bool>(MembershipController.AccountAdd(request.Action)); 
     } 
} 

用于处理请求的C＃代码是

[DataContract(Namespace = "")] 
    public class SMProcess<T> : BaseRequest 
    { 

     public SMProcess(T obj) 
     { 
      // TODO: Complete member initialization 
      this.Action = obj; 

     } 
     [DataMember] 
     public T Action { get; set; } 
    }

Answer 1

您的JSON请求应该是这样的

[OperationContract] 
     [WebInvoke(UriTemplate = "AccountAdd", Method = "POST")] 
     SMProcessResponse<bool> AccountAdd(SMProcess<User> request); 

和你的JSON数据

var userinfo = { "request": { "Action": { "Address": Adress, "Children": [], "CityId": 0, "Email": "waheed@gmail.com", "HomeUser": true, "ImagePath": "C:/Waheed.jpg", "IpAdress": "192.168.1.3", "IsActive": true, "LastLogin": "\/Date(1358852299323+0500)\/", "Name": "Waheed Iqbal", "Password": "111111", "PhoneNumber": "+923226270150", "ProfileHit": 10, "ShowEmail": true, "ShowPhoneNumber": true, "SubscribeNews": true, "UserID": 1}} } 

后编辑的Web.config

<behavior name="Services.webHttpBehavior"> 
      <webHttp defaultOutgoingResponseFormat="Json" automaticFormatSelectionEnabled="true" defaultBodyStyle="WrappedRequest" /> 
     </behavior>

您需要将正确的WebInvoke属性应用于WCF操作。看你的JSON请求，我相信它应该像

[OperationContract] 
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json))] 
SMProcessResponse<bool> AccountAdd(SMProcess<User> request) 

注意包裹体风格（或WrappedRequest）需要使输入JSON将被视为包裹一个（即参数名称将是对财产传入的JSON）。

除此之外，您可能会遇到问题与您的SMProcess<T>反序列化，因为它没有任何参数少构造函数。

无论如何，我会建议你做一个简单的服务声明（和实现）如

public SMProcessResponse<bool> AccountAdd(User request) 
{ 
    return new SMProcessResponse<bool>(MembershipController.AccountAdd(request)); 
} 

，然后开始添加额外的嵌套等
