Asp.net web api 404找不到在使用Asp.net核心中间件和.map时获取响应

下面是我编写的一个中间件的代码片段，它接收api请求并验证它，然后发送响应

但当请求在那个时候有效时，它不调用API，它显示404NotFound错误

中间件代码段

启动

控制器代码段

它是一个简单的API，没有任何身份验证属性

    [Route("api/[controller]")]
public class MoviesAPIController : Controller
{
    IMovies _IMovies;
    public MoviesAPIController(IMovies imovies)
    {
        _IMovies = imovies;
    }

    // GET: api/values
    [HttpGet]
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    // GET api/values/5
    [HttpGet("{id}")]
    public string Get(int id)
    {
        return "value";
    }

    // POST api/values
    [HttpPost]
    public List<MoviesTB> Post([FromQuery]string key)
    {
        return _IMovies.GetMusicStore();
    }

输出

依照

Map*扩展用作管道分支的约定。映射根据给定请求路径的匹配来分支请求管道。如果请求路径以给定路径开始，则执行分支

你需要像这样注册你的中间件

app.UseMiddleware<ApiKeyValidatorsMiddleware>();

或者也可以在地图中添加mvc。或者改用UseWhen。

    [Route("api/[controller]")]
public class MoviesAPIController : Controller
{
    IMovies _IMovies;
    public MoviesAPIController(IMovies imovies)
    {
        _IMovies = imovies;
    }

    // GET: api/values
    [HttpGet]
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    // GET api/values/5
    [HttpGet("{id}")]
    public string Get(int id)
    {
        return "value";
    }

    // POST api/values
    [HttpPost]
    public List<MoviesTB> Post([FromQuery]string key)
    {
        return _IMovies.GetMusicStore();
