404 嘗試將上游路徑路由到 Ocelot 中的下游路徑

在將傳入的 http 請求轉發到下游路徑時，我遇到了這個警告/錯誤。

Ocelot.DownstreamRouteFinder.Middleware.DownstreamRouteFinderMiddleware：警告：requestId：80000025-0004-fd00-b63f-84710c7967bb，previousRequestId：沒有先前的請求 id，消息：DownstreamRouteFinderMiddleware 設置管道錯誤。IDownstreamRouteFinder 返回錯誤程式碼：UnableToFindDownstreamRouteError 消息：無法匹配上游路徑的路由配置：/getDepartment，動詞：GET。

程序.cs

public class Program
{
   public static void Main(string[] args)
   {
       CreateWebHostBuilder(args).Build().Run();
   }

   public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
      WebHost.CreateDefaultBuilder(args)
      .ConfigureAppConfiguration((host, config) =>
      {
          config.AddJsonFile("ocelot.json");
      })
   .UseStartup<Startup>();
}

啟動.cs

public IConfiguration Configuration { get; }

public Startup(IConfiguration configuration)
{
   Configuration = configuration;
}

// This method gets called by the runtime. Use this method to add services to the container.
// For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
public void ConfigureServices(IServiceCollection services)
{
   services.AddOcelot(Configuration);
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public async void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
   if (env.IsDevelopment())
   {
       app.UseDeveloperExceptionPage();
   }

   await app.UseOcelot();

   app.Run(async (context) =>
   {
       await context.Response.WriteAsync("Hello World!");
   });
}

豹貓.json

{
 "ReRoutes": [
   {
     "DownstreamPathTemplate": "api/department",
     "DownstreamScheme": "http",
     "DownstreamHostAndPorts": [
       {
         "Host": "localhost",
         "Port": 44388
       }
     ],
     "UpstreamPathTemplate": "/getDepartment",
     "UpstreamHttpMethod": [
       "Get"
     ]
   }
 ],
 "GlobalConfiguration": {
   "BaseUrl": "http://localhost:5000"
 }
}

我在此收到錯誤 404。

如果您使用的是最新版本 (16.0.0)，請在 ocelot.json 中將“ReRoutes”更改為“Routes”。

我遇到了同樣的問題，然後遇到了這個拉取請求，解釋說它已被更改為與新的 Microsoft 反向代理項目 (YARP) 相匹配。他們的文件需要更新。 https://github.com/ThreeMammals/Ocelot/pull/1239
