//新建DateTimeJsonConverter 类
public class DateTimeJsonConverter : JsonConverter<DateTime>
    {
        public override DateTime Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
        {
            return DateTime.Parse(reader.GetString());
        }

        public override void Write(Utf8JsonWriter writer, DateTime value, JsonSerializerOptions options)
        {
            writer.WriteStringValue(value.ToString("yyyy-MM-dd HH:mm:ss"));
        }
    }

// startup写的  
 services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Latest).AddJsonOptions(option =>
            {
              //格式化返回日期去除T
                option.JsonSerializerOptions.Converters.Add(new DateTimeJsonConverter());
            });
