c# EasyHttp (http请求库)

介绍:EasyHttp

      EasyHttp http请求类库，支持net4.0++
      github:https://github.com/EasyHttp/EasyHttp

使用：

环境：net4.0 、EasyHttp（1.7版本）

准备工作：准备webapi调用接口

public class UnityController : ApiController
    {
        private IUserService _userService = null;
        public UnityController(IUserService userService)
        {
            _userService = userService;
        }

        // GET api/<controller>
        public IEnumerable<Student> Get()
        {
            //return UnityFactoryUtil.GetServer<IUserService>().GetList();
            return _userService.GetList();
        }



        // POST api/<controller>
        public string Post([FromBody]string value)
        {
