概述
Ocelot面向使用.NET運行微型服務/面向服務的體系結構的人員，這些體系結構需要在系統中具有統一的入口點，特別是我想與IdentityServer參考和承載令牌輕松集成，Ocelot是按特定順序排列的一堆中間件，Ocelot將HttpRequest物件操作到由其配置指定的狀態，直到到達請求構建器中間件，在該中間件中它創建一個HttpRequestMessage物件，該物件用于向下游服務發出請求，發出請求的中間件是Ocelot管道中的最后一件事，它不會呼叫下一個中間件，有一塊中間件可將HttpResponseMessage映射到HttpResponse物件，然后將其回傳給客戶端，基本上，它具有許多其他功能，
代碼實作
1、新建api客戶端1
2、新建api 網關test
3、nuget安裝Ocelot
4、Program檔案添加ConfigureAppConfiguration
public class Program { public static void Main(string[] args) { CreateHostBuilder(args).Build().Run(); } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureAppConfiguration(conf => { conf.AddJsonFile("ocelot.json", false, true); }) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); }); }
5、Startup檔案配置
services.AddOcelot(Configuration);
app.UseOcelot().Wait();
6、網關專案下添加檔案ocelot.json
{ "ReRoutes": [ { "DownstreamPathTemplate": "/api/WeatherForecast/GetList", "DownstreamScheme": "http", "DownstreamHostAndPorts": [ { "Host": "localhost", "Port": 5000 } ], "UpstreamPathTemplate": "/GetList", "UpstreamHttpMethod": [ "Get" ] }, { "DownstreamPathTemplate": "/{everything}", "DownstreamScheme": "http", "DownstreamHostAndPorts": [ { "Host": "localhost", "Port": 5000 } ], "UpstreamPathTemplate": "/{everything}", "UpstreamHttpMethod": [ "Post" ] }, { "DownstreamPathTemplate": "/api/WeatherForecast/GetModel?id={s1}", "DownstreamScheme": "http", "DownstreamHostAndPorts": [ { "Host": "localhost", "Port": 5000 } ], "UpstreamPathTemplate": "/GetModel?id={s1}", "UpstreamHttpMethod": [ "Get" ] } ] }
7、2個專案運行，測驗
