关于web api 中 日期格式问题解决方案

在构造函数或者 全局开始的时候调用这个

        public BossApiController()
        {
            JsonMediaTypeFormatter jsonFormatter = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
            JsonSerializerSettings jSettings = new Newtonsoft.Json.JsonSerializerSettings()
            {
                Formatting = Formatting.Indented,
                DateTimeZoneHandling = DateTimeZoneHandling.Utc
            };
            jSettings.Converters.Add(new MyDateTimeConvertor());
            jsonFormatter.SerializerSettings = jSettings;
        }

相关类有：

    public class MyDateTimeConvertor : DateTimeConverterBase
    {
        public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
        {
            return DateTime.Parse(reader.Value.ToString());
        }

        public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
        {
            writer.WriteValue(((DateTime)value).ToString("yyyy-MM-dd HH:mm:ss"));
        }
    }
