新建JsonNetResult类:JsonResult
public class JsonNetResult: JsonResult { public JsonNetResult() { Settings = new JsonSerializerSettings { ReferenceLoopHandling=ReferenceLoopHandling.Ignore, DateFormatString= "yyyy-MM-dd HH:mm:ss", ContractResolver=new Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver()//json中属性开头字母小写的驼峰命名 }; } public JsonSerializerSettings Settings { get; private set; } public override void ExecuteResult(ControllerContext context) { if (context == null) throw new ArgumentNullException("context"); //不允许GET请求 if (this.JsonRequestBehavior == JsonRequestBehavior.DenyGet && string.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase)) throw new InvalidOperationException("JSON GET is not allowed"); HttpResponseBase response = context.HttpContext.Response; response.ContentType = string.IsNullOrEmpty(this.ContentType) ? "application/json" : this.ContentType; if (this.ContentEncoding != null) response.ContentEncoding = this.ContentEncoding; if (this.Data == null) return; var scriptSerializer = JsonSerializer.Create(this.Settings); scriptSerializer.Serialize(response.Output, this.Data); } }
新建JsonNetActionFilter过滤器:
public class JsonNetActionFilter: IActionFilter { public void OnActionExecuted(ActionExecutedContext filterContext) { if (filterContext.Result is JsonResult && !(filterContext.Result is JsonNetResult)) { JsonResult jsonResult = (JsonResult)filterContext.Result; JsonNetResult jsonNetResult = new JsonNetResult(); jsonNetResult.ContentEncoding = jsonResult.ContentEncoding; jsonNetResult.ContentType = jsonResult.ContentType; jsonNetResult.Data = jsonResult.Data; jsonNetResult.JsonRequestBehavior = jsonResult.JsonRequestBehavior; jsonNetResult.MaxJsonLength = jsonResult.MaxJsonLength; jsonNetResult.RecursionLimit = jsonResult.RecursionLimit; filterContext.Result = jsonNetResult; } } public void OnActionExecuting(ActionExecutingContext filterContext) { } }
在Global中添加
GlobalFilters.Filters.Add(new JsonNetActionFilter());
控制器:
[HttpGet] public ActionResult TestJson() { return View(); } [HttpPost] public ActionResult TestJson(FormCollection fc) { Dog dog = new Dog() { BirthDay = DateTime.Now, Id = 5, Name = "旺财" }; return Json(dog); //return new JsonNetResult() { Data = dog }; }
前端:
<script type="text/javascript"> $(function () { $("#btn1").click(function () { $.ajax({ url: "/Home/TestJson", dataType: "json", type: "post", success: function (data) { alert(data.name); alert(data.birthDay); }, error: function () { alert("ajax错误"); } }); }); }); </script>
