启动多个服务

如何在 rk-boot 中,启动多个服务?

概述#

通过 rk-boot,用户可以在一个进程里面,启动多个 Entry。

用户还可以同时启动 GoFrame 服务和 gRPC 等服务。

快速开始#

1.安装#

$ go get github.com/rookie-ninja/rk-boot/v2
$ go get github.com/rookie-ninja/rk-gf

2.创建 boot.yaml#

gf:
  - name: alice
    port: 8080
    enabled: true
  - name: bob
    port: 8081
    enabled: true

3.创建 main.go#

package main

import (
  "context"
  "fmt"
  "github.com/gogf/gf/v2/net/ghttp"
  "github.com/rookie-ninja/rk-boot/v2"
  "github.com/rookie-ninja/rk-gf/boot"
  "net/http"
)

func main() {
  // Create a new boot instance.
  boot := rkboot.NewBoot()

  // Register handler
  alice := rkgf.GetGfEntry("alice")
  alice.Server.BindHandler("/v1/greeter", Greeter)

  bob := rkgf.GetGfEntry("bob")
  bob.Server.BindHandler("/v1/greeter", Greeter)

  // Bootstrap
  boot.Bootstrap(context.TODO())

  boot.WaitForShutdownSig(context.TODO())
}

func Greeter(ctx *ghttp.Request) {
  ctx.Response.WriteHeader(http.StatusOK)
  ctx.Response.WriteJson(&GreeterResponse{
    Message: fmt.Sprintf("Hello %s!", ctx.GetQuery("name").String()),
  })
}

type GreeterResponse struct {
  Message string
}

4.验证#

$ curl  "localhost:8080/v1/greeter?name=rk-dev"
{"Message":"Hello rk-dev!"}

$ curl  "localhost:8081/v1/greeter?name=rk-dev"
{"Message":"Hello rk-dev!"}

Cheers#
