Question

我在'post'.am上遇到问题时，用户对象总是为空。我在我的智慧结束并且已经研究了好几天，所以如果有任何想法，请帮助！提前致谢

我的Jquery看起来像这样

$(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WCF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));
        }
}

流程请求的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; }
    }

这是我的Web.config

<configuration>
        <connectionStrings>
   //here is connection string
  </connectionStrings>

Answer 1

您需要将正确的WebInvoke属性应用于WCF操作。看看你的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)

请注意，需要包装的正文样式（或WrappedRequest），以便将输入JSON视为包装的（即参数名称将是传入JSON的属性）。

除此之外，您可能会遇到SMProcess<T>反序列化的问题，因为它没有任何参数较少的构造函数。

无论如何，我建议你从简单的服务声明（和实现）开始，例如

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。

您的JSON请求应该是这样的

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

和您的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}} }

编辑Web.config后

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

欢呼声

将JSON对象发布到WCF服务对象始终为null
