Csharp 在路由中使用枚举

在使用控制器时，您可以在路径中使用枚举，但您必须添加以下内容

builder.Services.AddControllers();
    .AddJsonOptions(options =>
        options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter()));

或

builder.Services.ConfigureHttpJsonOptions(options =>
{
    options.SerializerOptions.Converters.Add(new JsonStringEnumConverter());
});
builder.Services.Configure<Microsoft.AspNetC或e.Mvc.JsonOptions>(options =>
{
    options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());
});

示例控制器

public enum Location
{
    London
}

[ApiController]
[Route("[controller]")]
public class WeatherF或ecastController : ControllerBase
{
    [HttpGet("{location}")]
    public IEnumerable<WeatherF或ecast> Get(Location location)
    {
        ....
    }
}

After that enums resolve c或rectly in swagger/openapi

"parameters": [
  {
    "name": "location",
    "in": "path",
    "required": true,
    "schema": {
      "$ref": "#/components/schemas/Location"
    }
  }
],

但是当我在最小的API中做同样的事情时

public enum Location
{
    London
}

app.MapGet("/weatherf或ecast/{location}", (Location location) =>
{
    ...
})
.WithName("GetWeatherF或ecast")
.WithOpenApi();

并添加相同的

builder.Services.ConfigureHttpJsonOptions(options =>
{
    options.SerializerOptions.Converters.Add(new JsonStringEnumConverter());
});
builder.Services.Configure<Microsoft.AspNetC或e.Mvc.JsonOptions>(options =>
{
    options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());
});

It just treats the route parameter as a string instead of a enum

"parameters": [
  {
    "name": "location",
    "in": "path",
    "required": true,
    "style": "simple",
    "schema": {
      "type": "string"
    }
  }
],

有没有办法配置最少的API来以相同的方式解析路由中的枚举？
