c# - 将 Ocelot 16.0 与 ASP.Net Core 3.1 集成无法正常工作，因为我需要将 Swagger 与 Ocelot 一起使用

Question

我已经将 Ocelot 与 Asp.Net Core 2.1 一起使用并且它可以正常工作，但是当与 Asp.Net Core 3.1 一起使用时它根本不起作用。在我看来，它没有获取“ocelot.json”文件。以下是我的 Program.cs 文件:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;

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

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureAppConfiguration((hostingContext, config) =>
                {
                    config
                        .SetBasePath(hostingContext.HostingEnvironment.ContentRootPath)
                        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                        .AddJsonFile($"appsettings.{hostingContext.HostingEnvironment.EnvironmentName}.json", optional: true, reloadOnChange: true)
                        .AddJsonFile($"ocelot.{hostingContext.HostingEnvironment.EnvironmentName}.json")
                        .AddEnvironmentVariables();
                })
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }
}

下面是 Startup.cs 文件:

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Ocelot.DependencyInjection;
using Ocelot.Middleware;

namespace ApiGateway
{
    public class Startup
    {
        private IConfiguration configuration;
        public Startup(IConfiguration configuration)
        {
            this.configuration = configuration;
        }


        // This method gets called by the runtime. Use this method to add services to the container.
        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 void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseHttpsRedirection();

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapGet("/", async context => {

                    await context.Response.WriteAsync("API GATEWAY FUNCIONANDO");
                });
            });

            app.UseOcelot().Wait();
        }
    }
}

下面是 ocelot.Development.json 文件:

{
  "ReRoutes": [
    {
      "DownstreamPathTemplate": "/TestApi/api/test",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": "80"
        }
      ],
      "UpstreamPathTemplate": "/getTest"
    },
    {
      "DownstreamPathTemplate": "/TestMicroS/api/values",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "localhost",
          "Port": "82"
        }
      ],
      "UpstreamPathTemplate": "/getValues"
    }
  ],
  "GlobalConfiguration": {
    
  }
}

我已从 YouTube 引用了上述所有配置，但它不起作用。本地网站正在运行，但是当我尝试访问 UpStream 路径时，它给我 localhost not found 404 错误。请协助我解决这个问题。

提前致谢。

尝试在您的 JSON 文件中将 ReRoutes 重命名为 Routes。
