服务发现

  1.   app.NewWebHostBuilder().
  2.       UseConfiguration(configuration).
  3.       ConfigureServices(func(serviceCollection *dependencyinjection.ServiceCollection) {
  4.       // 依赖注入 Nacos 服务发现组件
  5.           nacos.UseServiceDiscovery(serviceCollection)
  6.    }).Build().Run()

Nacos配置：

  1. yoyogo:
  2.   application:
  3.     name: demo_dev
  4.     metadata: "develop"
  5.   cloud:
  6.     discovery:
  7.       cache:
  8.         ttl: 30     # seconds 服务列表缓存时间 （秒）
  9.       register-enable: true  # 是否注册自身  (默认true ,非必填)
  10.       type: "nacos"
  11.       metadata:
  12.         url: "localhost"   #local1;local2 使用";"分隔.
  13.         port: 8848
  14.         namespace: "a3ae02e6-79e9-4150-bcfd-93eb8f9b0235"
  15.         group: "mygroup1"
  16.         cluster: ""
  17.         auth:
  18.           enable: true
  19.           username: "root"
  20.           password: "1234"

获取服务实例

新建一个Controller，并在GetSD函数中获取demo_dev服务的所有实例

  1. type SDController struct {
  2.     mvc.ApiController
  3.     discoveryCache  servicediscovery.Cache
  4.     discoveryClient servicediscovery.IServiceDiscoveryClient
  5. }
  7. func NewSDController(sd servicediscovery.IServiceDiscoveryClient, cache servicediscovery.Cache) *SDController {
  8.     return &SDController{discoveryClient: sd, discoveryCache: cache}
  9. }
  11. func (controller SDController) GetSD() mvc.ApiResult {
  12.     serviceList := controller.discoveryClient.GetAllInstances("yoyogo_demo_dev")
  13.     return controller.OK(serviceList)
  14. }
  16. func (controller SDController) GetServices() mvc.ApiResult {
  17.     serviceList, _ := controller.discoveryClient.GetAllServices()
  18.     return controller.OK(serviceList)
  19. }
