在 Go 中公开公共 JWK

我试图在GO中公开jwks端点，但我生成模数的方式似乎不正确. 有没有人已经做过了，可以告诉我我做错了什么？

以下是我如何生成我的密钥openssl genrsa -out private_key.pem 2048和公共部分openssl rsa -in private_key.pem -pubout -out public_key.pub

在我的围棋程序中，我是这样做的

var verifyKey *rsa.PublicKey
verifyBytes, err := ioutil.ReadFile("public_key.pub")
verifyKey, err = jwt.ParseRSAPublicKeyFromPEM(verifyBytes)
    
modulus := base64.StdEncoding.EncodeToString((*verifyKey.N).Bytes())
exponent := base64.StdEncoding.EncodeToString(big.NewInt(int64(verifyKey.E)).Bytes())

以下是密钥是如何公开的

func (s *ExtAuthzServer) ServeHTTP(response http.ResponseWriter, request *http.Request) { 
    if request.URL.Path == "/.well-known/jwks.json" {
        log.Printf("[HTTP] jwks requested")
        n := base64.StdEncoding.EncodeToString((*verifyKey.N).Bytes())
        e := base64.StdEncoding.EncodeToString(big.NewInt(int64(verifyKey.E)).Bytes())
        keys := PublicKeysData{
            Keys: []KeyData{KeyData{"RSA", "go-ext-authz", "sig", n, e}},
        }
        response.WriteHeader(http.StatusOK)
        b, _ := json.Marshal(keys)
        _, _ = response.Write([]byte(b))
        return
    }    
}

具有以下 struct 定义

type PublicKeysData struct {
    Keys []KeyData `json:"keys"`
}

type KeyData struct {
    Kty string `json:"kty"`
    Kid string `json:"kid"`
    Use string `json:"use"`
    N   string `json:"n"`
    E   string `json:"e"`
}

这是一个curl 的输出(我指的是HTTPie)

    ]
}
