关于WCF接收AJAX请求,Json数据的解析。

 $('#btn4').bind('click', function () {
var did = { ID: 99999, Name: 'aaa' }; $.ajax({ url: uri + 'GetPersonByPerson', type: 'get', dataType: 'jsonp', contentType: "application/json", data: did, cache: false, timeout: 10000, success: function (data) { alert(data.Name); } }); });

前端页面调用wcf接口,入参是引用类型。

    [DataContract]
    public class Person
    {
        [DataMember]
        public int ID { get; set; }

        [DataMember]
        public string Name { get; set; }
    }


  public interface IServices
    {
        [OperationContract]
        [WebGet(ResponseFormat=WebMessageFormat.Json)]
        Person GetPersonByPerson(Person person);
    }

但是wcf接收到请求后,解析不出Person的值。person一直为null。为什么person会是null呢,ajax请求的时候,已经有入参   var did = { ID: 99999, Name: 'aaa' };为什么呢?求园友帮忙。

 

 public class TestServices : IServices
    {   
        public Person GetPersonByPerson(Person person)//这里始终是person==null
        {
            if (person != null)
                person.Name = "i am No." + person.ID.ToString();
            else
                person = new Person() { ID=-1,Name="i am No.-1" };

            return person;
        }
    }

下面是我的WCF的配置。

已经解决是,是json入参的问题。这样写就没问题了。但是如果层次比较深的话,又是个麻烦吧。

var did = { person: '{ "ID": 99999, "Name": "aaa" }' };
