C# 没有为ApicController调用Midleware

ASP.NET Core 3.1项目有一个自定义中间件，它根据请求url域注入路由数据值

public class IdentificationMiddleware {
    private readonly RequestDelegate _next;

    public IdentificationMiddleware(RequestDelegate next)
    {
        this._next = next ?? throw new ArgumentNullException(nameof(next));
    }

    public async Task InvokeAsync(HttpContext context) {
       var identification = ...;  
       if (!identification) {
           context.abort();
       } else {
          var routeData = context.GetRouteData();
          routeData.Values.Add("identification", identification); 
       }
       await _next(context);
    }
}

中间件已在启动中注册：

app.UseRouting();

app.UseMiddleware<IdentificationMiddleware>();

app.UseEndpoints(endpoints =>
{
});

为什么在api控制器中调用操作之前不调用中间件？有可能叫人来吗？如何修复它？

您的

ApiAction（）

方法签名中不需要

[FromRoute]字符串标识吗？谢谢。这就不同了。
[Route("api/some")]
[ApiController]
public sealed class SomeApiController : ControllerBase
{
    [HttpGet("apiAction")]
    public async Task<IActionResult> ApiAction(
        string identification,
        [FromQuery] long id)
    {
    }
 }

{
    "type":"https://tools.ietf.org/html/rfc7231#section-6.5.1",
    "title":"One or more validation errors occurred.",
    "status":400,
    "traceId":"guid",
    "errors":{
        "identification":["The identification field is required."]
    }
}
