將JSON對象發布到WCF服務對象始終為null

Question

我在使用“ post”時遇到麻煩。am使User Object始終為null。我不知所措，並且已經對此進行了數天的研究，因此，如果有人有任何想法，請提供幫助！ 提前致謝

我的jQuery看起來像這樣

$(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WCF的C＃代碼是

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

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

流程請求的C＃代碼為

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

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

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

這是我的Web.config

<configuration>
        <connectionStrings>
   //here is connection string
  </connectionStrings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />

             maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10"
             applicationName="/" />
      </providers>
    </membership>

    <profile>
      <providers>
        <clear/>
        <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/"/>
      </providers>
    </profile>

    <roleManager enabled="false">
      <providers>
        <clear/>
        <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" />
        <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" />
      </providers>
    </roleManager>

      <service name="SelectionMall.Services.Membership">

Answer 1

您需要將正確的WebInvoke屬性應用於WCF操作。 查看您的JSON請求，我相信應該是這樣的

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

注意，需要使用包裝的主體樣式（或WrappedRequest ），以便將輸入JSON視為包裝的樣式（即，參數名稱將是傳入JSON的屬性）。

除此之外，您可能會遇到SMProcess<T>反序列化的問題，因為它沒有減少構造函數的參數。

無論如何，我建議您從簡單的服務聲明（和實現）開始，例如

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

然后開始添加額外的嵌套等

Answer 2

您的JSON請求應該是這樣的

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

和你的JSOn數據

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}} }

編輯Web.config之后

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