英文:
key is of invalid type
问题
背景：我正在尝试使用Go语言重写此指南中的第一步。
我有以下内容：
- 一个JWT令牌（
tokenString），使用RS256算法，可以在这里查看。 - 一个密钥（
key），采用SSH RFC-4253格式。
我正在尝试使用该密钥验证JWT令牌。以下是我的代码：
import (
"fmt"
"github.com/golang-jwt/jwt/v4"
)

然而，我遇到了错误：
密钥类型无效
希望能得到帮助或其他可行的库！

Any help or other libraries that work would be great!

我认为你需要在jwt.KeyFunc中返回一个*rsa.PublicKey而不是[]byte。根据你的密钥字符串，这只是一个猜测。
原来的代码：
token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
return []byte(key), nil
})
尝试修改为：
token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
return jwt.ParseRSAPublicKeyFromPEM([]byte(key))
})
你也可以根据签名方法使用switch case语句：
token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
switch token.Method {
case jwt.SigningMethodHS256.Alg():
return []byte(key)
case jwt.SigningMethodRS512.Alg():
return jwt.ParseRSAPublicKeyFromPEM([]byte(key))
// 其他签名方法...
}
...
})
英文:
I'm think you'll have to return a *rsa.PublicKey instead of []byte from the jwt.KeyFunc. This is a guess looking at your key string
Instead of:
token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
return []byte(key), nil
})
try:
token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
return jwt.ParseRSAPublicKeyFromPEM([]byte(key))
})
you could also use a switch case on the signing method:
token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
switch token.Method {
case jwt.SigningMethodHS256.Alg():
return []byte(key)
case jwt.SigningMethodRS512.Alg():
return jwt.ParseRSAPublicKeyFromPEM([]byte(key))
// and so on...
}
...
})
