WCF服务端与使用HttpClient的Android客户端简单示例
WCF服务端
Contract
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using System.Web;
namespace Contract
{
///
/// 服务接口
///
///
/// WebInvoke - 指示服务操作在逻辑上就是调用操作，而且可由Web编程模型调用
/// WebGet - 指示服务操作在逻辑上就是检索操作，而且可由Web编程模型调用
/// UriTemplate - 用于服务操作的统一资源标识符（URI）模版。URI模版可以将一个URI或一组URI映射到服务操作
/// Method - 与操作关联的写作方法，默认为 POST
/// ResponseFormat - 指定从服务操作发出的响应的格式。Xml或Json
/// BodyStyle - 指定body里面的封装
///
[ServiceContract]
public interface IWcfService
{
///
/// GET - 无参数 - 返回值为字符串数组
///
/// GetStudentNames();
///
/// GET - 无参数 - 返回值为自定义类型的数组
