Variables ¶
var GinCtxKey ctxkey = "gin"
GinCtxKey key of gin ctx that saved in request.context
var Logger log.Logger
Functions ¶
func EnableMetric ¶
func EnableMetric(srv *gin.Engine, options ...MetricsOptFunc) (err error)
EnableMetric enable metrics for exsits gin server
func FromStd ¶
func FromStd(handler http.HandlerFunc) gin.HandlerFunc
FromStd convert std handler to gin.Handler, with gin context embedded
func GetGinCtxFromStdCtx ¶
GetGinCtxFromStdCtx get gin context from standard request.context by GinCtxKey
func NewHTTPMetricSrv ¶
NewHTTPMetricSrv start new gin server with metrics api
func NewLoggerMiddleware ¶
func NewLoggerMiddleware(optfs ...LoggerMwOptFunc) gin.HandlerFunc
NewLoggerMiddleware middleware to logging
Types ¶
type Auth ¶
type Auth struct {
// contains filtered or unexported fields
}
Auth JWT cookie based token generator and validator. Cookie looks like <defaultAuthTokenName>:`{<defaultAuthUserIDCtxKey>: "xxxx"}`
Example ¶
package main
import (
"net/http"
"github.com/Laisky/zap"
"github.com/gin-gonic/gin"
"github.com/golang-jwt/jwt/v4"
)
type UserClaims struct {
jwt.StandardClaims
}
func main() {
auth, err := NewAuth([]byte("f32lifj2f32fj"))
if err != nil {
Logger.Panic("try to init gin auth got error", zap.Error(err))
}
ctx := &gin.Context{}
uc := &UserClaims{}
if err := auth.GetUserClaims(ctx, uc); err != nil {
Logger.Warn("user invalidate", zap.Error(err))
} else {
Logger.Info("user validate", zap.String("uid", uc.Subject))
}
if _, err = auth.SetAuthHeader(ctx, WithSetAuthHeaderClaim(uc)); err != nil {
Logger.Error("try to set cookie got error", zap.Error(err))
}
Server := gin.New()
Server.Handle("ANY", "/authorized/", FromStd(DemoHandle))
}
func DemoHandle(w http.ResponseWriter, r *http.Request) {
// middlewares
if _, err := w.Write([]byte("hello")); err != nil {
Logger.Error("http write", zap.Error(err))
}
}
Output:
func NewAuth ¶
func NewAuth(secret []byte, opts ...AuthOptFunc) (a *Auth, err error)
NewAuth create new Auth
