我正在使用.NET最小API，并且遇到了枚举的JSON序列化/反序列化行为的问题。尽管我尝试改变使用字符串而不是整数的行为，但Swashbuckle.AspNetCore的Swagger文档仍然将枚举表示为整数。

using System.Text.Json.Serialization;

var builder = WebApplication.CreateBuilder(args);

// Docs: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/minimal-apis?view=aspnetcore-7.0#configure-json-deserialization-options-globally
builder.Services.ConfigureHttpJsonOptions(options =>
{
    options.SerializerOptions.Converters.Add(new JsonStringEnumConverter());
});

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.MapPost("/api/v1/test", (TestRequest request) => Results.Ok(request));

app.Run();

public enum GridType
{
    Arithmetic,
    Geometric
}

public class TestRequest
{
    public required string Name { get; init; }
    public required GridType Type { get; set; }
}

字符串
但是当Swagger UI打开时，我仍然会得到一个枚举的整数：

{
  "name": "string",
  "type": 0
}

型
预期输出为：

{
  "name": "string",
  "type": "Arithmetic"
}

型
