Question

我有一个wcf服务和一个角度应用程序，它发送插入或更新客户的请求。 wcf服务接收请求，调用正确的方法但方法参数值为null。我已尝试将WebMessageBodyStyle更改为Bare，但后来甚至没有调用方法本身。我尝试了[FromBody]属性，包括对象和字符串参数。两者都输入方法但参数值仍为null。我没有想法。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：

Host: localhost:49258

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

Answer 1

您正在使用包装请求，请将您的JSON打包为：

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

在wcf方法参数中反序列化json为null
