很多时候（如Ajax）我们需要从Web应用中得到标准的反馈以便进行数据分析。

为此，我将各类返回标准化封装，客户端将统一得到 JSON：[{"status":200,"message":"success","data":[Object]}]，有利于建立统一的数据处理模型。

public class ReturnStd
{
public class ReturnJson
{
public string Status { get; set; }
public string Message { get; set; }
public object Data { get; set; }
}
public static ReturnJson ComJson(string responseMessage, string responseCode, object rtnData = null)
{
ReturnJson returnJson = new ReturnJson()
{
Status = responseCode,
Message = responseMessage,
Data = rtnData ?? string.Empty
};
return returnJson;
} public static ReturnJson Success(object rtnData = null)
{
ReturnJson returnJson = new ReturnJson()
{
Status = "200",
Message = string.Empty,
Data = rtnData?? string.Empty
};
return returnJson;
} public static ReturnJson Error(string responseMessage, string responseCode = "400", object rtnData = null)
{
ReturnJson returnJson = new ReturnJson()
{
Status = responseCode,
Message = responseMessage ?? string.Empty,
Data = rtnData ?? string.Empty
};
return returnJson;
} public static ReturnJson ModelError(ModelStateDictionary modelState, string responseCode = "400", object rtnData = null)
{
string messages = string.Join("; ", modelState.Values.SelectMany(x => x.Errors).Select(x => x.ErrorMessage)); ReturnJson returnJson = new ReturnJson()
{
Status = responseCode,
Message = messages,
Data = rtnData ?? string.Empty
};
return returnJson;
} public static ReturnJson NotAuthorize(string responseMessage, string responseCode = "90", object rtnData = null)
{
ReturnJson returnJson = new ReturnJson()
{
Status = responseCode,
Message = responseMessage ?? string.Empty,
Data = rtnData ?? string.Empty
};
return returnJson;
} }

如何使用？

[HttpGet]
public JsonResult GetUsers(long lastUpdateTicks=0)
{
List<SYS_User_OnCloud> rtnData = _context.SYS_User_OnClouds.Where(u => ((long?)u.LastUpdateTicks?? 0) >= lastUpdateTicks).ToList();
return Json(ReturnStd.Success(rtnData));
}
