1.效果

基于Ocelot，实现对3个微服务的轮询调用，实现不停机更新，无缝更新；

2.环境要求

1.部署环境：腾讯云的轻量化应用服务器

2.系统环境：Window Server 2016

3..net托管包：dotnet-hosting-9.0.4-win.exe

3.配置开放端口号

3.1 端口号说明：端口5000（服务1），端口5001（服务2），端口5002（服务3），端口5010（Ocelot）

3.2 在服务器管理平台上的开放以上4个端口号

2.3 配置入站规则端口号

4.服务1的代码

4.1 Program.cs

var builder = WebApplication.CreateBuilder(args);// 添加Swagger
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen(c =>
{c.SwaggerDoc("v1", new() { Title = "ServerAPI1", Version = "v1" });
});builder.WebHost.ConfigureKestrel(serverOptions => { }).UseUrls("http://*:5000"); // 允许所有Hostbuilder.Services.AddControllers();
var app = builder.Build();// 配置Swagger
if (app.Environment.IsDevelopment())
{app.UseSwagger();app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "ServerAPI1 v1"));
}app.UseRouting();
app.MapControllers();app.Run();

4.2 接口

using Microsoft.AspNetCore.Mvc;
using ServerAPI1.Models;namespace ServerAPI1.Controllers
{[ApiController][Route("api/[controller]")][Produces("application/json")]public class ValuesController : ControllerBase{/// <summary>/// 获取服务基本信息/// </summary>[HttpGet("info")][ProducesResponseType(200)]public IActionResult GetInfo(){return Ok(new { Service = "ServerAPI1", Port = 5000 });}/// <summary>/// 计算服务 (A+B)/// </summary>/// <param name="model">输入参数</param>[HttpPost("calculate")][ProducesResponseType(200)][ProducesResponseType(400)]public IActionResult Calculate([FromBody] TestModel model){if (!ModelState.IsValid) return BadRequest(ModelState);return Ok(new { Result = 123 + 321, Input = model });}}
}

4.2 数据模型

using System.ComponentModel.DataAnnotations;namespace ServerAPI1.Models
{public class TestModel{[Required][StringLength(100)]public string AAA { get; set; }[StringLength(200)]public string BBB { get; set; }}
}

5.服务2的代码

5.1 Program.cs

var builder = WebApplication.CreateBuilder(args);// 添加Swagger
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen(c =>
{c.SwaggerDoc("v1", new() { Title = "ServerAPI2", Version = "v1" });
});builder.WebHost.ConfigureKestrel(serverOptions => { }).UseUrls("http://*:5001"); // 允许所有Hostbuilder.Services.AddControllers();
var app = builder.Build();// 配置Swagger
if (app.Environment.IsDevelopment())
{app.UseSwagger();app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "ServerAPI2 v1"));
}app.UseRouting();
app.MapControllers();app.Run();

5.2 接口

using Microsoft.AspNetCore.Mvc;
using ServerAPI2.Models;namespace ServerAPI2.Controllers
{[ApiController][Route("api/[controller]")][Produces("application/json")]public class ValuesController : ControllerBase{/// <summary>/// 获取服务元数据/// </summary>[HttpGet("info")][ProducesResponseType(200)]public IActionResult GetInfo(){return Ok(new { Service = "ServerAPI2", Port = 8016 });}/// <summary>/// 字符串转换服务/// </summary>/// <param name="model">输入参数</param>[HttpPost("calculate")][ProducesResponseType(200)][ProducesResponseType(400)]public IActionResult Transform([FromBody] TestModel model){if (!ModelState.IsValid) return BadRequest(ModelState);return Ok(new { Result = $"{model.AAA}-{model.BBB}".ToUpper() });}}
}

5.3 数据模型

    using System.ComponentModel.DataAnnotations;namespace ServerAPI2.Models{public class TestModel{[Required][StringLength(100)]public string AAA { get; set; }[StringLength(200)]public string BBB { get; set; }}}

6.服务3的代码

6.1 Program.cs

var builder = WebApplication.CreateBuilder(args);// 添加Swagger
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen(c =>
{c.SwaggerDoc("v1", new() { Title = "ServerAPI3", Version = "v1" });
});builder.WebHost.ConfigureKestrel(serverOptions => { }).UseUrls("http://*:5002"); // 允许所有Hostbuilder.Services.AddControllers();
var app = builder.Build();// 配置Swagger
if (app.Environment.IsDevelopment())
{app.UseSwagger();app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "ServerAPI3 v1"));
}app.UseRouting();
app.MapControllers();app.Run();

6.2 接口

using Microsoft.AspNetCore.Mvc;
using ServerAPI3.Models;namespace ServerAPI3.Controllers
{[ApiController][Route("api/[controller]")][Produces("application/json")]public class ValuesController : ControllerBase{/// <summary>/// 获取服务元数据/// </summary>[HttpGet("info")][ProducesResponseType(200)]public IActionResult GetInfo(){return Ok(new { Service = "ServerAPI4", Port = 8016 });}/// <summary>/// 字符串转换服务/// </summary>/// <param name="model">输入参数</param>[HttpPost("calculate")][ProducesResponseType(200)][ProducesResponseType(400)]public IActionResult Transform([FromBody] TestModel model){if (!ModelState.IsValid) return BadRequest(ModelState);return Ok(new { Result = $"{model.AAA}-{model.BBB}".ToUpper() });}}
}

6.3 数据模型

    using System.ComponentModel.DataAnnotations;namespace ServerAPI3.Models{public class TestModel{[Required][StringLength(100)]public string AAA { get; set; }[StringLength(200)]public string BBB { get; set; }}}

7.Ocelot的代码

7.1 Program.cs

using Ocelot.DependencyInjection;
using Ocelot.Middleware;var builder = WebApplication.CreateBuilder(args);// 强制指定 Kestrel 端口（优先级最高）
builder.WebHost.ConfigureKestrel(serverOptions =>
{serverOptions.ListenAnyIP(5010); // 监听所有IP的5010端口
});builder.Configuration.AddJsonFile("ocelot.json", optional: false, reloadOnChange: true);
builder.Services.AddOcelot(builder.Configuration);var app = builder.Build();
await app.UseOcelot();
app.Run();
