ASP.NET Core默认提供了三种Serializer的实现:JsonSerializer、XmlSerializer和Formatters。它们都是从抽象类InputFormatter和OutputFormatter派生而来。我们可以根据需要自定义Serializer。
下面是一个使用JsonSerializer自定义Serializer的示例:
首先,创建一个实现InputFormatter和OutputFormatter的类CustomJsonSerializer。
using Microsoft.AspNetCore.Mvc.Formatters;
using Newtonsoft.Json;
public class CustomJsonSerializer : InputFormatter, IOutputFormatter
{
private readonly JsonSerializerSettings _settings;
public CustomJsonSerializer(JsonSerializerSettings settings)
{
_settings = settings;
SupportedMediaTypes.Add("application/json");
}
protected override bool CanReadType(Type type)
{
return true; // 可以处理任何类型
}
protected override Task
然后,在Startup类中注册CustomJsonSerializer。
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Newtonsoft.Json;
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(options =>
{
options.InputFormatters.Insert(0, new CustomJsonSerializer(new JsonSerializerSettings
{
Formatting = Formatting.Indented,
ContractResolver = new CamelCasePropertyNamesContractResolver()
}));
options.OutputFormatters.Insert(0, new CustomJsonSerializer(new JsonSerializerSettings
{
