服务发现

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

eureka配置：

  1. yoyogo:
  2.   application:
  3.     name: demo_dev
  4.     metadata: "develop"
  5.   cloud:
  6.     discovery:
  7.       cache:
  8.         ttl: 30     # seconds
  9.       type: "eureka"
  10.       metadata:
  11.         address: 
  12.           - "http://localhost:5000/eureka"

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 UserController struct {
  2.     Mvc.ApiController
  3.     discoveryClient serverdiscovery.IServerDiscovery
  4. }
  6. func NewUserController(sd serverdiscovery.IServerDiscovery) *UserController {
  7.     return &UserController{ discoveryClient: sd}
  8. }
  10. func (controller UserController) GetSD() mvc.ApiResult {
  11.     serviceList := controller.discoveryClient.GetAllInstances("demo_dev")
  12.     return controller.OK(serviceList)
  13. }
