解决方法：
[HttpGet]
public HttpResponseMessage getsystemtime()
{
cltime time = new cltime();
time.datetime = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
string relsut = JsonConvert.SerializeObject(time);
var resp = new HttpResponseMessage { Content = new StringContent(relsut, System.Text.Encoding.UTF8, "application/json") };
return resp;
}
