🧪 Example: Secure Server Setup

package main

import (
	log "github.com/sirupsen/logrus"
	"github.com/softwareplace/goserve/internal/handler"
	"github.com/softwareplace/goserve/internal/service/apiservice"
	"github.com/softwareplace/goserve/internal/service/login"
	"github.com/softwareplace/goserve/internal/service/provider"
	"github.com/softwareplace/goserve/logger"
	"github.com/softwareplace/goserve/security"
	"github.com/softwareplace/goserve/security/secret"
	"github.com/softwareplace/goserve/server"
)

func init() {
	logger.LogSetup()
}

var (
	userPrincipalService = login.NewPrincipalService()
	securityService      = security.New(
		userPrincipalService,
	)
	loginService   = login.NewLoginService(securityService)
	secretProvider = provider.NewSecretProvider()
	secretService  = secret.New(
		secretProvider,
		securityService,
	)
)

func main() {
	server.Default().
		LoginResourceEnabled(true).
		SecretKeyGeneratorResourceEnabled(true).
		LoginService(loginService).
		SecretService(secretService).
		SecurityService(securityService).
		EmbeddedServer(apiservice.Register).
		Get(apiservice.ReportCallerHandler, "/report/caller").
		SwaggerDocHandler("./internal/resource/pet-store.yaml").
		StartServer()
}

📋 API Testing

Start server

go run test/main.go

Open http://localhost:8080/swagger/index.html

Start in protected mode

PROTECTED_API=true go run test/main.go

Without token:

{
  "message": "You are not allowed to access this resource",
  "statusCode": 401,
  "timestamp": 1742781093916
}

With valid token:

curl -X GET 'http://localhost:8080/swagger/index.html' \
  -H 'accept: application/json' \
  -H 'X-Api-Key: <your-jwt-token>'
