```go
package main

import (
	"net/http"

	"github.com/gin-gonic/gin"
	"gitee.ltd/go-oauth2/gin-server"
	"github.com/go-oauth2/oauth2/v4/manage"

	"github.com/go-oauth2/oauth2/v4/server"
	"github.com/go-oauth2/oauth2/v4/store"
)

func main() {
	manager := manage.NewDefaultManager()

	// token store
	manager.MustTokenStorage(store.NewFileTokenStore("data.db"))

	// client store
	clientStore := store.NewClientStore()
	clientStore.Set("000000", &models.Client{
		ID:     "000000",
		Secret: "999999",
		Domain: "http://localhost",
	})
	manager.MapClientStorage(clientStore)

	// Initialize the oauth2 service
	ginserver.InitServer(manager)
	ginserver.SetAllowGetAccessRequest(true)
	ginserver.SetClientInfoHandler(server.ClientFormHandler)

	g := gin.Default()

	auth := g.Group("/oauth2")
	{
		auth.GET("/token", ginserver.HandleTokenRequest)
	}

	api := g.Group("/api")
	{
		api.Use(ginserver.HandleTokenVerify())
		api.GET("/test", func(c *gin.Context) {
			ti, exists := c.Get(ginserver.DefaultConfig.TokenKey)
			if exists {
				c.JSON(http.StatusOK, ti)
