c# - wcf方法参数中的反序列化json为空

Question

我有一个 wcf 服务和一个发送插入或更新客户请求的角度应用程序。 wcf 服务收到请求，调用正确的方法，但方法参数值为空。我曾尝试将 WebMessageBodyStyle 更改为 Bare，但该方法本身甚至没有被调用。我尝试使用 [FromBody] 属性，同时使用对象和字符串参数。都进入了方法但是参数值还是null。我没主意了。帮助将不胜感激。

        [ServiceContract]
    public interface ICustomerService
    {
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest,
            RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        [OperationContract]
        bool InsertOrUpdateCustomer(Customer customer);

    }
    [DataContract]
    public class Customer
    {
        [DataMember]
        public CustomerType Type { get; set; }
        [DataMember]
        public String Name { get; set; }
        [DataMember]
        public string Email { get; set; }
        [DataMember]
        public String Password { get; set; }
        [DataMember]
        public String NewPassword { get; set; }
        [DataMember]
        public virtual IList<Address> Addresses { get; set; }
        [DataMember]
        public virtual IList<CustomerLicense> CustomerLicenses { get; set; }
    }

    public enum CustomerType
    {
        Organizational = 0,
        Individual = 1
    }
    [DataContract]
    public class Address
    {
    }
    [DataContract]
    public class CustomerLicense
    {
    }

    public class Service : ICustomerService
    {

        public bool InsertOrUpdateCustomer(Customer customer)
        {
            try
            {
                if (customer == null)
                    throw new ArgumentNullException(nameof(customer));
                //do work for insert/update
                return true;
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine(ex.Message);
                return false;
            }
        }
    }

下面我将请求 Angular 应用程序发送到 wcf 服务:

{"Password":"passwordtest","Name":"nametest","NewPassword":"newPasswordTest","Type":1,"Email":"test@test.be"}

Answer 1

您正在使用包装请求，像这样包装您的 JSON:

{"customer":{"Password":"passwordtest","Name":"nametest","NewPassword":"newPasswordTest","Type":1,"Email":"test@test.be", "Addresses":"null", "CustomerLicenses":"null" }}
