这对我有用:
import (
"errors"
"fmt"
"github.com/dgrijalva/jwt-go"
"github.com/gin-gonic/gin"
"github.com/lestrrat-go/jwx/jwk"
"net/http"
"os"
)
func verifyToken(token *jwt.Token) (interface{}, error) {
// make sure to replace this with your actual URL
// https://docs.aws.amazon.com/cognito/latest/developerguide/amazon-cognito-user-pools-using-tokens-verifying-a-jwt.html#amazon-cognito-user-pools-using-tokens-step-2
jwksURL := "COGNITO_JWKS_URL"
set, err := jwk.FetchHTTP(jwksURL)
if err != nil {
return nil, err
}
keyID, ok := token.Header["kid"].(string)
if !ok {
return nil, errors.New("expecting JWT header to have string kid")
}
keys := set.LookupKeyID(keyID)
if len(keys) == 0 {
return nil, fmt.Errorf("key %v not found", keyID)
}
if key := set.LookupKeyID(keyID); len(key) == 1 {
return key[0].Materialize()
}
return nil, fmt.Errorf("unable to find key %q", keyID)
}
在我的情况下,我这样称呼它(使用 AWS Lambda gin
)。如果您使用不同的方式来管理请求,请确保将其替换为http.Request
您可能正在使用的任何其他框架:
func JWTVerify() gin.HandlerFunc {
return func(c *gin.Context) {
tokenString := c.GetHeader("AccessToken")
_, err := jwt.Parse(tokenString, verifyToken)
if err != nil {
c.AbortWithStatus(http.StatusUnauthorized)
}
}
}
