1. Prepare go get github.com/dgrijalva/jwt-gogo get github.com/gin-gonic/gin2. Code 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.Esh2Zge0vO1BAW1GeR5wurWP3H1jUIaMf3tcSaUwkzA / / http://localhost:9090/refresh/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NjA1MTIyNDMsImlhdCI6MTU2MDUwODYxMCwidXNlcl9pZCI6MSwicGFzc3dvcmQiOiIxMjM0NTYiLCJ1c2VybmFtZSI6ImRvbmciLCJmdWxsX25hbWUiOiJkb25nIiwicGVybWlzc2lvbnMiOltdfQ.Xkb_J8MWXkwGUcBF9bpp2Ccxp8nFPtRzFzOBeboHmg0} const (ErrorReason_ServerBusy = "Server busy" ErrorReason_ReLogin = "Please login again") func sayHello (c * gin.
