Apple 公钥错误，无法创建 error:09091064:PEM routines:PEM_read_bio_ex:bad base64 decode

问题
正在做sign in with Apple，按照官方的说明，去接口拿到公钥来验证token，结果发现这个拿过来的公钥完全就不对。怎么都不读。公钥文档

GET https://appleid.apple.com/auth/keys 

返回的JSON

      "kty": "RSA",

问题
这公钥根本就解不出来，也无法生成，一直报错 string(61) "error:09091064:PEM routines:PEM_read_bio_ex:bad base64 decode"

字符串转key

/**

 * @return string
 */
public static function str2pubicKey($key)
{
    $key = str_replace(['-', '_'], ['+', '/'], trim($key));
    $key = trim(chunk_split(trim($key), 64, "\n"), "\n");
    return sprintf("-----BEGIN PUBLIC KEY-----\n%s\n-----END PUBLIC KEY-----\n", $key);
}

现在无法解码，报错一直提示这个
