.net Core how to solve the problem of returning time format with T in WebAPI
This article mainly introduces the relevant knowledge of ".net Core how to solve the problem of returning time format T in WebAPI". The editor shows you the operation process through an actual case. The method of operation is simple, fast and practical. I hope this article ".net Core how to solve the problem of returning time format T in WebAPI" can help you solve the problem.
The problem of returning time format with T is encountered in the project development, as shown in the figure:
Directly return this result to the front end, the front end is very difficult to deal with this time format problem, so the back end needs to process this format when the data is returned.
Create a new Order class:
Using System;namespace WebApiTest {public class Order {public int ID {get; set;} public DateTime OrderTime {get; set;}
Create a new formatting class DatetimeJsonConverter, inherit from JsonConverter, and override the methods in it:
Using System;using System.Text.Json;using System.Text.Json.Serialization Namespace WebApiTest {/ public class DatetimeJsonConverter: JsonConverter {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"));}
Then modify the ConfigureServices method of the Startup class
Public void ConfigureServices (IServiceCollection services) {# region solves the problem of returning time with T services.AddControllers () .AddJsonOptions (configure = > {configure.JsonSerializerOptions.Converters.Add (new DatetimeJsonConverter ());}); # endregion}
Return the result
