在将传入的 http 请求转发到下游路径时，我遇到了这个警告/错误。

Ocelot.DownstreamRouteFinder.Middleware.DownstreamRouteFinderMiddleware：警告：requestId：80000025-0004-fd00-b63f-84710c7967bb，previousRequestId：没有以前的请求 id，消息：DownstreamRouteFinderMiddleware 设置管道错误。IDownstreamRouteFinder 返回错误代码：UnableToFindDownstreamRouteError 消息：无法匹配上游路径的路由配置：/getDepartment，动词：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>();
}

启动.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!");
    });
}

豹猫.json

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

我在此收到错误 404。

如果您使用的是最新版本 (16.0.0)，请在 ocelot.json 中将“ReRoutes”更改为“Routes”。

我遇到了同样的问题，然后遇到了这个拉取请求，解释说它已被更改为与新的 Microsoft 反向代理项目 (YARP) 相匹配。他们的文档需要更新。 https://github.com/ThreeMammals/Ocelot/pull/1239
