go中jwt使用

1.引入包"github.com/dgrijalva/jwt-go"

2.设置token并返回

func setToken() string {

token := jwt.New(jwt.SigningMethodHS256)

claims := make(jwt.MapClaims)

claims[“exp”] = time.Now().Add(time.Hour * time.Duration(1)).Unix() // 设置超时时间

claims[“iat”] = time.Now().Unix()

token.Claims = claims

tokenString, err := token.SignedString([]byte(“mobile”))

if err != nil {

return “”

}

return tokenString

}

3.获取校验token

token, err := request.ParseFromRequest(c.Request, request.AuthorizationHeaderExtractor, func(token *jwt.Token) (i interface{}, e error) {

return []byte(“mobile”), nil

})

if err == nil {

if token.Valid {

// token有效可以进行其他操作

} else {

fmt.Println(“Token is not vaild”) // token无效

}

} else {

fmt.Println( “unauthorized access to this resource”) // 未找到token

}
