1. 直接启动Consul服务,然后再启动web服务,web服务主动通知consul
cmd consul agent -dev
webapi配置文件 appsettings.json
{ "Logging": { "LogLevel": { "Default": "Information", "Microsoft": "Warning", "Microsoft.Hosting.Lifetime": "Information" } }, "AllowedHosts": "*", "AppName": "ServiceA" }
webapi ServiceA服务
public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { services.AddControllers(); } //关闭的时候在consul中移除 private void OnStopped() { var client = new ConsulClient(); //根据ID在consul中移除当前服务 client.Agent.ServiceDeregister("ServiceA"); } private void OnStart() { var client = new ConsulClient(); //健康检查 var httpCheck = new AgentServiceCheck() { //服务出错一分钟后 会自动移除 DeregisterCriticalServiceAfter = TimeSpan.FromMinutes(1), //每10秒发送一次请求到 下面的这个地址 这个地址就是当前API资源的地址 Interval = TimeSpan.FromSeconds(10), HTTP = $"http://localhost:5011/health" }; var agentReg = new AgentServiceRegistration() { //这台资源服务的唯一ID ID = "ServiceA", Check = httpCheck, Address = "localhost", Name = "ApiService", Port = 5011, Tags = new string[1] { "ServiceA" } }; client.Agent.ServiceRegister(agentReg).ConfigureAwait(false); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IWebHostEnvironment env, Microsoft.AspNetCore.Hosting.IApplicationLifetime lifetime) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } //注册项目启动的方法 lifetime.ApplicationStarted.Register(OnStart); //注册项目关闭的方法 lifetime.ApplicationStarted.Register(OnStopped); app.UseRouting(); app.UseAuthorization(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); }); } }
ServiceB 服务
public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { services.AddControllers(); } //关闭的时候在consul中移除 private void OnStopped() { var client = new ConsulClient(); //根据ID在consul中移除当前服务 client.Agent.ServiceDeregister("ServiceB"); } private void OnStart() { var client = new ConsulClient(); //健康检查 var httpCheck = new AgentServiceCheck() { //服务出错一分钟后 会自动移除 DeregisterCriticalServiceAfter = TimeSpan.FromMinutes(1), //每10秒发送一次请求到 下面的这个地址 这个地址就是当前API资源的地址 Interval = TimeSpan.FromSeconds(10), HTTP = $"http://localhost:5012/health" }; var agentReg = new AgentServiceRegistration() { //这台资源服务的唯一ID ID = "ServiceB", Check = httpCheck, Address = "localhost", Name = "ApiService", Port = 5012 }; client.Agent.ServiceRegister(agentReg).ConfigureAwait(false); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IWebHostEnvironment env, Microsoft.AspNetCore.Hosting.IApplicationLifetime lifetime) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } //注册项目启动的方法 lifetime.ApplicationStarted.Register(OnStart); //注册项目关闭的方法 lifetime.ApplicationStarted.Register(OnStopped); app.UseRouting(); app.UseAuthorization(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); }); } }
2 consul服务的配置文件直接配置多个webapi服务
根目录新建service.json
{ "services": [ { "id": "ApiServiceA", "name": "ApiService", "tags": [ "ApiServiceA" ], "address": "localhost", "port": 5011, "checks": [ { "id": "ApiServiceA_Check", "name": "ApiServiceA_Check", "http": "http://localhost:5011/health", "interval": "10s", "tls_skip_verify": false, "method": "GET", "timeout": "1s" } ] }, { "id": "ApiServiceB", "name": "ApiService", "tags": [ "ApiServiceB" ], "address": "localhost", "port": 5012, "checks": [ { "id": "ApiServiceB_Check", "name": "ApiServiceB_Check", "http": "http://localhost:5012/health", "interval": "10s", "tls_skip_verify": false, "method": "GET", "timeout": "1s" } ] } ] }
cmd consul agent -dev -config-dir=D:\MicroService\【工具】\consul_1.9.0_windows_amd64
访问地址 http://localhost:8500
