废话不多说，直接入正题，供各位朋友参考~！
注意：服务器使用wcf rest风格，传递数据使用Json格式，但是并没有包装该格式，因为都是实现单参，双参必须要包装，当然单参也可以包装 ^_^
服务器端代码
wcf接口：
namespace Test{ // 注意: 如果更改此处的接口名称 "IService1"，也必须更新 Web.config 中对 "IService1" 的引用。 [ServiceContract] public interface IService1 { [OperationContract] [WebInvoke(UriTemplate="contact_entity",RequestFormat=WebMessageFormat.Json,ResponseFormat=WebMessageFormat.Json,Method="POST")] Person contact_entity(Person ps); [OperationContract] [WebInvoke(UriTemplate = "contact_entity_return_string", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, Method = "POST")] string contact_entity_return_string(Person ps); [OperationContract] [WebInvoke(UriTemplate = "test1", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, Method = "POST")] string test1(string pass_string); }} wcf接口实现
namespace Test{ // 注意: 如果更改此处的类名“Service1”，也必须更新 Web.config 和关联的 .svc 文件中对“Service1”的引用。 public class Service1 : IService1 { #region IService1 成员 public Person contact_entity(Person ps) { // throw new NotImplementedException(); ps.username = "successful"; return ps; } public string contact_entity_return_string(Person ps) { // throw new NotImplementedException(); if (ps.username == "jwc") { return "successful"; } else { return "failth"; } } public string test1(string pass_string) { pass_string = pass_string.Replace("{", "").Replace("}", "").Trim(); string[] arry = pass_string.Split(new char[1] { ':' }); if (arry[1] == "jwc") { return "successful"; } else { return "faith"; } } #endregion }} Person代码：
namespace Test{ [DataContract] public class Person { [DataMember] public int id { get; set; } [DataMember] public string username { get; set; } [DataMember] public string password { get; set; } }} web.config
