ocelot简单例子(路由)

环境：
目标框架 .NET Core 2.1
控制台应用程序
Ocelot 8.0.3

.NET Core 2.1的运行方式为：
找到编译后的dll，
打开cmd命令行，
输入：dotnet Gateway.dll
如果缺少环境，按cmd的提示进行环境安装

效果：
访问http://localhost:9000，
会随机路由到：
http://localhost:1000
http://localhost:1001

Startup.cs

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.DependencyInjection;
using Ocelot.DependencyInjection;
using Ocelot.Middleware;

namespace Gateway
{
    public class Startup
    {
        // 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();
            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

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

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

Program.cs

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;

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

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args) .UseUrls("http://*:9000")
                   .ConfigureAppConfiguration((hostingContext, config) =>
               {
                   config
                       .SetbasePath(hostingContext.HostingEnvironment.ContentRootPath)
                       .AddJsonFile("ocelot.json")
                       .AddEnvironmentVariables();
               })
                .UseStartup();
    }
}
