运行多个服务

请参阅 issues 并尝试以下示例:

  1. package main
  2. import (
  3. "log"
  4. "net/http"
  5. "time"
  6. "github.com/gin-gonic/gin"
  7. "golang.org/x/sync/errgroup"
  8. )
  9. var (
  10. g errgroup.Group
  11. )
  12. func router01() http.Handler {
  13. e := gin.New()
  14. e.Use(gin.Recovery())
  15. e.GET("/", func(c *gin.Context) {
  16. c.JSON(
  17. http.StatusOK,
  18. gin.H{
  19. "code": http.StatusOK,
  20. "error": "Welcome server 01",
  21. },
  22. )
  23. })
  24. return e
  25. }
  26. func router02() http.Handler {
  27. e := gin.New()
  28. e.Use(gin.Recovery())
  29. e.GET("/", func(c *gin.Context) {
  30. c.JSON(
  31. http.StatusOK,
  32. gin.H{
  33. "code": http.StatusOK,
  34. "error": "Welcome server 02",
  35. },
  36. )
  37. })
  38. return e
  39. }
  40. func main() {
  41. server01 := &http.Server{
  42. Addr: ":8080",
  43. Handler: router01(),
  44. ReadTimeout: 5 * time.Second,
  45. WriteTimeout: 10 * time.Second,
  46. }
  47. server02 := &http.Server{
  48. Addr: ":8081",
  49. Handler: router02(),
  50. ReadTimeout: 5 * time.Second,
  51. WriteTimeout: 10 * time.Second,
  52. }
  53. g.Go(func() error {
  54. return server01.ListenAndServe()
  55. })
  56. g.Go(func() error {
  57. return server02.ListenAndServe()
  58. })
  59. if err := g.Wait(); err != nil {
  60. log.Fatal(err)
  61. }
  62. }
