MVC 控制器中直接访问url 的方式

public void ShowDetailsImg()
{
//生成MD5码
string path = @"D:\其他\Test\WebApplication2\WebApplication2\Image\123\";
string md5 = StringExtensions.ToMD5Hash(path);
string url = string.Format("http://172.16.9.53:8012/Handler2.ashx?path={0}&md5={1}", path, md5);

string jsonResult = new HttpClient().GetStringAsync(url).Result;

System.Web.HttpContext.Current.Response.Write(jsonResult);
System.Web.HttpContext.Current.Response.End();

//JToken jtoken = JToken.Parse("");

//return Json(new { a= 1});
}
