解决.net core 3.1 json日期带T的问题

///添加一个扩展类  

public class DatetimeJsonConverter : JsonConverter<DateTime>
{
public override DateTime Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
{
if (reader.TokenType == JsonTokenType.String)
{
if (DateTime.TryParse(reader.GetString(), out DateTime date))
return date;
}
return reader.GetDateTime();
}

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

//最后在容器中注入下 Startup.cs

services.AddControllers().AddJsonOptions(opt =>
{
opt.JsonSerializerOptions.Converters.Add(new DatetimeJsonConverter());
});
