我试图让我的动作返回一个JsonResult它全部的性能在驼峰。
我有一个简单的模型:
public class MyModel
{
public int SomeInteger { get; set; }
public string SomeString { get; set; }
}
而一个简单的控制器操作:
public JsonResult Index()
{
MyModel model = new MyModel();
model.SomeInteger = 1;
model.SomeString = "SomeString";
return Json(model, JsonRequestBehavior.AllowGet);
}
调用这个动作方法现在返回一个包含下列数据的JsonResult:
{"SomeInteger":1,"SomeString":"SomeString"}
对于我的应用我需要的行动返回驼峰的数据,在某种程度上是这样的:
{"someInteger":1,"someString":"SomeString"}
是否有任何优雅的方式来做到这一点?
我一直在寻找到可能的解决方案在这里,发现MVC3 JSON序列:如何控制房地产的名字呢? 在那里设置数据成员定义到模型的每一个属性,但我真的不希望这样做。
此外,我发现,他们说,这是可能的解决正是这种问题的链接: http://www.asp.net/web-api/overview/formats-and-model-binding/json-and-xml-系列化#json_camelcasing 。 它说:
写骆驼外壳JSON属性名,在不改变你的数据模型,设置串行的CamelCasePropertyNamesContractResolver:
var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
在这个博客上的一个条目http://frankapi.wordpress.com/2012/09/09/going-camelcase-in-asp-net-mvc-web-api/也mentiones该解决方案,并指出,你可以简单地把它添加到RouteConfig.RegisterRoutes来解决这个问题。 我试过,但我不能使它工作。
难道你们有我在那里做错了任何想法?
控制器的JSON函数只是包装器创建JsonResults:
protected internal JsonResult Json(object data)
{
return Json(data, null /* contentType */, null /* contentEncoding */, JsonRequestBehavior.DenyGet);
}
protected internal JsonResult Json(object data, string contentType)
{
return Json(data, contentType, null /* contentEncoding */, JsonRequestBehavior.DenyGet);
}
protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding)
{
return Json(data, contentType, contentEncoding, JsonRequestBehavior.DenyGet);
}
protected internal JsonResult Json(object data, JsonRequestBehavior behavior)
{
return Json(data, null /* contentType */, null /* contentEncoding */, behavior);
}
protected internal JsonResult Json(object data, string contentType, JsonRequestBehavior behavior)
{
return Json(data, contentType, null /* contentEncoding */, behavior);
}
protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding, JsonRequestBehavior behavior)
{
return new JsonResult
{
Data = data,
ContentType = contentType,
ContentEncoding = contentEncoding,
JsonRequestBehavior = behavior
};
}
JsonResult内部使用JavaScriptSerializer,所以你不要有关于序列化过程控制:
public class JsonResult : ActionResult
{
public JsonResult()
{
JsonRequestBehavior = JsonRequestBehavior.DenyGet;
}
public Encoding ContentEncoding { get; set; }
public string ContentType { get; set; }
public object Data { get; set; }
public JsonRequestBehavior JsonRequestBehavior { get; set; }
/// <summary>
/// When set MaxJsonLength passed to the JavaScriptSerializer.
/// </summary>
public int? MaxJsonLength { get; set; }
/// <summary>
/// When set RecursionLimit passed to the JavaScriptSerializer.
/// </summary>
public int? RecursionLimit { get; set; }
public override void ExecuteResult(ControllerContext context)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
if (JsonRequestBehavior == JsonRequestBehavior.DenyGet &&
String.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
{
throw new InvalidOperationException(MvcResources.JsonRequest_GetNotAllowed);
}
HttpResponseBase response = context.HttpContext.Response;
if (!String.IsNullOrEmpty(ContentType))
{
response.ContentType = ContentType;
}
else
{
response.ContentType = "application/json";
}
if (ContentEncoding != null)
{
response.ContentEncoding = ContentEncoding;
}
if (Data != null)
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
if (MaxJsonLength.HasValue)
{
serializer.MaxJsonLength = MaxJsonLength.Value;
}
if (RecursionLimit.HasValue)
{
serializer.RecursionLimit = RecursionLimit.Value;
}
response.Write(serializer.Serialize(Data));
}
}
}
你必须创建自己的JsonResult,写自己的Json控制器的功能(如果你需要/想这一点)。 您可以创建新的或改写现有的,它是由你。 这种链接也可能会感兴趣。
如果你想从你的行动将附着于驼峰表示法你必须做什么返回一个JSON字符串是创建一个JsonSerializerSettings实例,并把它作为JsonConvert.SerializeObject(A,B)方法的第二个参数。
public string GetSerializedCourseVms()
{
var courses = new[]
{
new CourseVm{Number = "CREA101", Name = "Care of Magical Creatures", Instructor ="Rubeus Hagrid"},
new CourseVm{Number = "DARK502", Name = "Defence against dark arts", Instructor ="Severus Snape"},
new CourseVm{Number = "TRAN201", Name = "Transfiguration", Instructor ="Minerva McGonal"}
};
var camelCaseFormatter = new JsonSerializerSettings();
camelCaseFormatter.ContractResolver = new CamelCasePropertyNamesContractResolver();
return JsonConvert.SerializeObject(courses, camelCaseFormatter);
}
