C# Ocelot没有'；重新定义微服务

我正在尝试实现我的微服务应用程序。 我已经在localhost:5001-base CRUD上编目了API微服务。 我想用Ocelot实现Api网关

Catalo.API launsetings.json：

"reservation_system.Catalo.Api": {
  "commandName": "Project",
  "launchBrowser": true,
  "launchUrl": "swagger/index.html",
  "applicationUrl": "http://localhost:5001",
  "environmentVariables": {
    "ASPNETCORE_ENVIRONMENT": "Development"
  }
}

API网关中的Program.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("appsettings.json", true, true)
                    .AddJsonFile($"appsettings.{host.HostingEnvironment.EnvironmentName}.json", true, true)
                    .AddEnvironmentVariables();
                    config.AddJsonFile("configuration.json");
                })
            .UseStartup<Startup>();
    }

我正试图通过 我得到了“你好，世界！”的回答。

这里有什么问题？

没有执行Ocelot中间件，因为您通过调用

Run（）

委托并写入响应流使请求管道短路

中间件组件在

Configure

方法中注册的顺序很重要。这些组件的调用顺序与它们的添加顺序相同

所以如果你移动

等待app.UseOcelot（）

up，进入

Configure（）

方法，就在

app.Run（）

之前，将执行Ocelot中间件

public class Startup
    {
        public IConfiguration Configuration { get; set; }

        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.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
            services.AddOcelot();
        }

        // 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();
            }

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