go gin+token(JWT)验证实现登陆验证

收集整理的这篇文章主要介绍了go gin+token(JWT)验证实现登陆验证，觉得挺不错的，现在分享给大家，也给大家做个参考。

1.准备

go get gIThub.COM/dgrijalva/jwt-gogo get github.com/gin-gonic/gin

 2.代码

package main import (	"errors"	"fmt"	"github.com/dgrijalva/jwt-go"	"github.com/gin-gonic/gin"	"net/http"	"time") func main() {
	r := gin.Default()	r.GET("/LOGin/:username/:password", login)	r.GET("/verify/:token", verify)	r.GET("/refresh/:token", refresh)	r.GET("/sayHello/:token", sayHello)	r.Run(":9090") 	//http://localhost:9090/login/dong/123456	//http://localhost:9090/verify/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NjA1MTIymtasIMLhdCI6MTU2MDUwODYXMCwidXNlcl9pZCI6MSwicGFzc3dvcmQiOiIxMjM0NTYiLCJ1c2VybmFtZSI6ImRvbmciLCJmdWxsX25hbWUiOiJkb25nIiwicGVybWlzc2lvbnMiOltDFQ.Esh1Zge0vO1BAW1GeR5wurWP3H1jUIaMf3tcSaUwkzA	//http://localhost:9090/refresh/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NjA1MTIyNDMsImlhdCI6MTU2MDUwODYxMCwidXNlcl9pZCI6MSwicGFzc3dvcmQiOiIxMjM0NTYiLCJ1c2VybmFtZSI6ImRvbmciLCJmdWxsX25hbWUiOiJkb25nIiwicGVybWlzc2lvbnMiOltdfQ.Xkb_J8MWXkwGUcBF9bpp2Ccxp8nFPtRzFzOBeboHmg0}
 const(	ErrorReason_ServerBusy = "服务器繁忙"	ErrorReason_ReLogin = "请重新登陆") func sayHello(c *gin.Context) {
	strToken := c.Param("token")	claim,err := verifyAction(strToken)	if err != nil {
		c.String(http.statusNotFound, err.Error())		return	}
	c.String(http.StatusOK, "hello,",claim.Username)}
 tyPE JWTClaims struct {
 // token里面添加用户信息，验证token后可能会用到用户信息	jwt.StandardClaims	UserID      int      `json:"user_id"`	Password    string   `json:"password"`	Username    string   `json:"username"`	FullName    string   `json:"full_name"`	Permissions []string `json:"permissions"`}
 VAR (	Secret     = "dong_tech" // 加盐	ExpireTime = 3600        // token有效期) func login(c *gin.Context) {
    	username := c.Param("username")	password := c.Param("password")	claims := &
JWTClaims{
		UserID:      1,		Username:    username,		Password:    password,		FullName:    username,		Permissions: []string{
}
,	}
	claims.IssuedAt = time.Now().Unix()	claims.ExpiresAt = time.Now().Add(time.Second * time.Duration(ExpireTime)).Unix()	signedToken,err:=getToken(claims)	if err!=nil{
		c.String(http.StatusNotFound, err.Error())		return	}
	c.String(http.StatusOK, signedToken)}
 func verify(c *gin.Context) {
	strToken := c.Param("token")	claim,err := verifyAction(strToken)	if err != nil {
		c.String(http.StatusNotFound, err.Error())		return	}
	c.String(http.StatusOK, "verify,",claim.Username)}
 func refresh(c *gin.Context) {
	strToken := c.Param("token")	claims,err := verifyAction(strToken)	if err != nil {
		c.String(http.StatusNotFound, err.Error())		return	}
	claims.ExpiresAt = time.Now().Unix() + (claims.ExpiresAt - claims.IssuedAt)	signedToken,err:=getToken(claims)	if err!=nil{
		c.String(http.StatusNotFound, err.Error())		return	}
	c.String(http.StatusOK, signedToken)}
 func verifyAction(strToken string) (*JWTClaims, error) {
    	token, err := jwt.ParseWithClaims(strToken, &
JWTClaims{
}
, func(token *jwt.Token) (interface{
}
, error) {
		return []byte(Secret), nil	}
)	if err != nil {
		return nil, errors.New(ErrorReason_ServerBusy)	}
	claims, ok := token.Claims.(*JWTClaims)	if !ok {
		return nil, errors.New(ErrorReason_ReLogin)	}
    	if err := token.Claims.Valid();
 err != nil {
		return nil, errors.New(ErrorReason_ReLogin)	}
	fmt.PRintln("verify")	return claims, nil}
 func getToken(claims *JWTClaims)(string,error){
	token := jwt.NewWithClaims(jwt.SigningMethodHS256, claims)	signedToken, err := token.SignedString([]byte(Secret))	if err != nil {
		return "",errors.New(ErrorReason_ServerBusy)	}
	return signedToken,nil}
    

运行结果如图：

访问接口

登陆
验证
刷新
http://localhost:9090/login/
http://localhost:9090/verify/
http://localhost:9090/refresh/
