ocelot简单例子

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 (); }}
