注意： controllerContext.Request.Content.ReadAsFormDataAsync().Result 和 controllerContext.Request.Content.ReadAsStringAsync().Result; 只能取，并且取完，后面子类中就获取不到了，必须就得重新赋值进去，这是我觉得很怪异的地方。

StringContent content = new StringContent(postContentData, Encoding.UTF8, contentType);
controllerContext.Request.Content = content;
