newtonsoft.json 指定某个属性使用特定的时间格式

intro

newtonsoft.json 是 .net 下最受欢迎 json 操作库,原为 json.net 后改名为 newtonsoft.json,之前一直推荐大家使用,除了性能好之外,主要是功能丰富,基本满足所有的可能用到的场景(不区分小写,现在还不行,,)。

遇到这样一个需求,全局使用一种时间格式,某些属性使用特殊的时间格式,这里以一个日期为例

solution

解决办法:自定义一个 converter,针对某一个属性使用,datetimeformatconverter源码:

using newtonsoft.json.converters;

namespace weihanli.common.json
{
  public class datetimeformatconverter : isodatetimeconverter
  {
    public datetimeformatconverter(string format)
    {
      datetimeformat = format;
    }
  }
}

在需要设置格式的属性上设置 converter https://github.com/weihanli/activityreservation/blob/dev/activityreservation.helper/viewmodels/reservationviewmodel.cs#l8

[display(name = "预约日期")]
[jsonconverter(typeof(datetimeformatconverter), "yyyy-mm-dd")]
public datetime reservationfordate { get; set; }

请求 api 地址 https://reservation.weihanli.xyz/api/reservation?pagenumber=1&pagesize=5,返回的数据如下所示:

{
    "data": [
        {
            "reservationfordate": "2019-06-10",
            "reservationfortime": "08:00~09:50",

            "reservationtime": "2019-06-11 12:45:14",
            "reservationstatus": 0
        },
        {
            "reservationfordate": "2019-06-17",
            "reservationfortime": "14:00-16:00",
            "reservationpersonphone": "138****3883",

        {
            "reservationfordate": "2019-06-17",
            "reservationfortime": "08:00-10:00",
            "reservationpersonphone": "132****4545",

            "reservationtime": "2019-06-10 01:44:52",
            "reservationstatus": 2
        },
        {
            "reservationfordate": "2019-06-22",
            "reservationfortime": "10:00~11:50",
            "reservationpersonphone": "132****3333",
            "reservationpersonname": "测**",
            "reservationunit": "测试",
            "reservationplacename": "多媒体工作室",
            "reservationactivitycontent": "测试",
            "reservationid": "27d0fb7a-ce14-4958-8636-dd10e5526083",
            "reservationtime": "2019-06-18 10:57:06",
            "reservationstatus": 1
        }
    ],
    "pagenumber": 1,
    "pagesize": 5,
    "totalcount": 18,
    "pagecount": 4,
    "count": 5
}

可以看到 reservationfordate 序列化之后返回的格式如我们指定的格式了~
