.net core 3.0 中是否有任何功能可以将 url 与其路由匹配

Question

我有一个包含 URL 的字符串，我想获得匹配此 URL 的路由。

假设 URL 字符串包含值

http://localhost/PerformOperation/accountId/Operation/operationId

并且我有一条名为 "PerformOperations" 的路线与此 url

相匹配

PerformOperation/{accountId}/{action}/{operationId}.

如何获得这条路线？ MVC 显然会根据每个请求执行此操作，但我不知道如何手动执行此操作。我有一个路线列表，我必须从 URL 中找到匹配的路线。

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseEndpointRouting();

    //Your custom middleware that does something with routing data
    app.Use((context, next) =>
    {
    // let assume we are asking for http://localhost:18159/home/index/22
    var endpointFeature = context.Features[typeof(Microsoft.AspNetCore.Http.Features.IEndpointFeature)]
                                            as Microsoft.AspNetCore.Http.Features.IEndpointFeature;

    Endpoint endpoint = endpointFeature?.Endpoint;

    if (endpoint != null)
    {
        var routePattern = (endpoint as Microsoft.AspNetCore.Routing.RouteEndpoint)?.RoutePattern
                                                                                    ?.RawText;

        // Example result : Name: AdRaker.Core.Web.Tracker.Controllers.HomeController.Index (AdRaker.Core.Web.Tracker) 
        var info1 = $"Name: {endpoint.DisplayName}";
        // Example result: Route Pattern: Home/Index/{id?}
        var info2 = $"Route Pattern: {routePattern}";
        // Example result: Metadata Types: Microsoft.AspNetCore.Mvc.ControllerAttribute, 
        // Microsoft.AspNetCore.Mvc.Controllers.ControllerActionDescriptor, Microsoft.AspNetCore.Routing.DataTokensMetadata, 
        // Microsoft.AspNetCore.Routing.RouteValuesAddressMetadata, Microsoft.AspNetCore.Mvc.Internal.ControllerActionFilter, 
        // Microsoft.AspNetCore.Mvc.ViewFeatures.SaveTempDataAttribute, Microsoft.AspNetCore.Mvc.ModelBinding.UnsupportedContentTypeFilter
        var info3 = $"Metadata Types: {string.Join(", ", endpoint.Metadata)}";
    }

    // Forward data to next middleware
    return next();
});

第一个中间件负责检查传入请求并将其与 endpoint.Without 匹配，端点数据将始终为空。
