网关以webapi 为例

using Ocelot.DependencyInjection;
using Ocelot.Middleware;
using Ocelot.Provider.Consul;namespace OcelotGateway
{public class Program{public static void Main(string[] args){var builder = WebApplication.CreateBuilder(args);// Add services to the container.//配置文件数据源builder.Configuration.AddJsonFile("Configuration.json", true,true);builder.Services.AddControllers();// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbucklebuilder.Services.AddEndpointsApiExplorer();builder.Services.AddSwaggerGen();builder.Services.AddOcelot().AddConsul();var app = builder.Build();// Configure the HTTP request pipeline.if (app.Environment.IsDevelopment()){app.UseSwagger();app.UseSwaggerUI();}//接受请求，转发app.UseOcelot();            //app.UseHttpsRedirection();//app.UseAuthorization();//app.MapControllers();app.Run();}}
}

实际的提供服务的程序 以webapi为例

ConsulHelper

 public  static class ConsulHelper{/// <summary>/// Consul注册/// </summary>/// <param name="configuration"></param>public static void ConsulRegist(this IConfiguration configuration){//找ConsulConsulClient client = new ConsulClient(c => {c.Address = new Uri("http://localhost:8500");c.Datacenter = "dc1";});string ip = string.IsNullOrWhiteSpace(configuration["ip"]) ? "localhost" : configuration["ip"];int port = string.IsNullOrWhiteSpace(configuration["weight"]) ? 1 : int.Parse(configuration["port"]);int weight = string.IsNullOrWhiteSpace(configuration["weight"]) ? 1 : int.Parse(configuration["weight"]);client.Agent.ServiceRegister(new AgentServiceRegistration(){//唯一的 ID = "service" + Guid.NewGuid(),//分组Name = "Zen",Address = ip,Port = port,Tags = new string[] { weight.ToString() },//心跳Check = new AgentServiceCheck(){//间隔多久一次Interval = TimeSpan.FromSeconds(12),//控制器HTTP = $"http://{ip}:{port}/Api/Health/Index",//检测等等时间Timeout = TimeSpan.FromSeconds(5),//失败后多久移除DeregisterCriticalServiceAfter = TimeSpan.FromSeconds(120)}});//命令行参数获取Console.WriteLine($"注册成功：{ip}{port}-weight:{weight}");}}

Program 中

using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.IdentityModel.Tokens;
using Microsoft.OpenApi.Models;
using System.Net;
using System.Text;namespace WebAPI

}

1、启动Consul

consul agent -dev

参考资料
2、启动webapi实际的服务

dotnet run --urls=“http://:2501" --port=2501 --ip=“localhost” --weight=2
dotnet run --urls="http://:2502” --port=2502 --ip=“localhost” --weight=2
dotnet run --urls=“http://*:2503” --port=2503 --ip=“localhost” --weight=2
3、启动网关 Ocelot
dotnet run --urls=“http://localhost:6299”
