使用Json.Net代替最简单的方法就是使用下面的JsonNetResult 来作为 ActionResult返回。
但是比较麻烦,还有很多其他方法。下面使用我研究的最没有“侵入性”的方法(什么是“侵入性”?
引入这个技术对系统的改动量),知道原理、会照着配置即可,不用记住。
下面这种做法是体现了“一夫当关万夫莫开”的AOP的思想。
1) Install-Package newtonsoft.json
2) 创建一个JsonNetResult继承自JsonResult(相当于自定义ActionResult)
public class JsonNetResult : JsonResult ???{ ???????public JsonNetResult() ???????{ ???????????Settings = new JsonSerializerSettings ???????????{ ???????????????ReferenceLoopHandling = ReferenceLoopHandling.Ignore,//忽略循环引用,如果设置为Error,则遇到循环引用的时候报错(建议设置为Error,这样更规范) ????????????????DateFormatString = "yyyy-MM-dd HH:mm:ss",//日期格式化,默认的格式也不好看 ????????????????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"); ???????????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); ???????} ???}
