# QuickStart

#### Add package 
```shell 
go get -u gitee.com/nanakura/gin-middleware-paseto
```

#### Register Middleware
```go
package main

import (
	auth "gitee.com/nanakura/gin-middleware-paseto"
	"gitee.com/nanakura/gin-middleware-paseto/maker"
	"github.com/gin-gonic/gin"
	"log"
	"net/http"
	"time"
)

type Server struct {
	router     *gin.Engine
	tokenMaker maker.Maker
}

func NewServer() *Server {
	tokenMaker, err := maker.NewPasetoMaker("YELLOW SUBMARINE, BLACK WIZARDRY")
	if err != nil {
		panic(err)
	}
	return &Server{
		router:     gin.Default(),
		tokenMaker: tokenMaker,
	}
}

func (s *Server) setupRouter() {
	authMiddleware := auth.NewDefaultPasetoAuthMiddleware(s.tokenMaker)
	r := s.router
	apiGroup := r.Group("/auth")
	apiGroup.Use(authMiddleware)
	apiGroup.GET("/", func(ctx *gin.Context) {
		ctx.JSON(http.StatusOK, gin.H{
			"status": "ok",
		})
	})
	r.POST("/login", func(ctx *gin.Context) {
		type loginPayload struct {
			Username string `json:"username"`
			Password string `json:"password"`
		}
		p := loginPayload{}
		err := ctx.ShouldBind(&p)
		if err != nil {
			log.Println(err)
			ctx.JSON(http.StatusBadRequest, gin.H{"error": err})
			return
		}
		username := p.Username
		token, err := s.tokenMaker.CreateToken(username, 24*time.Hour)
		if err != nil {
			ctx.JSON(http.StatusInternalServerError, gin.H{"error": err})
			return
		}
		ctx.JSON(http.StatusOK, gin.H{"token": token})
	})
}

func main() {
	server := NewServer()
	server.setupRouter()
	err := server.router.Run(":8080")
	if err != nil {
		log.Fatal(err)
	}
}
