我试图在Go语言中公开一个JWK的端点，但是我生成模数的方式似乎不正确，我做错了什么？
下面是我生成密钥的方法：

openssl genrsa -out private_key.pem 2048

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())

下面是密钥的公开方式：

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
    }
}

使用以下结构定义

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"`
}

下面是curl的输出（我指的是HTTPie）：

HTTP/1.1 200 OK

Content-Type: text/plain; charset=utf-8

            "kty": "RSA",

        }
    ]
}
