我已经为此工作太久了。我正在寻找截至 2016 年 9 月的工作示例,用于验证 Google idToken,例如

使用 Google 推荐的方式并为 jwks_uri 拉取“accounts.google.com/.well-known/openid-configuration”并拉取“www.googleapis.com/oauth2/v3/certs”,从而为
{ "kty": "RSA", "alg": "RS256", “使用”:“签名”, “孩子”:“6c781942d849ba2ecda8cedb72d34357fc95b327”, "n": "s1dt5wFFaYl-Bt7Yb7QgWEatLJfxwWDhbd5yvm2Z4d1PRgNVQa9kwOArQNoOJ-b-oZnXLVFsVASUXEAumGf1ip5TVCQmMBKqlchSDNuoZfoWdpCCX7jx4gNuS43pS6VqV3QDjWnoXRTHaUi5pZEbpAmWpOeG_CfmewNVwBXPFx8-mtvEdtxIrspX4ayXTViR4vHc7MhQhUxllFbocxMjJysDQuZV9wN3MI0lVtQdf52SKJwF3lhvWA9-WAEZ1q8wq-I93Sfte95RaFjDqCH--Sh-8DjhK4OvgItcEGd5QRHjdLvrayPwaDQbpMRN2n3BkVWIxKJubtRiSeWbawCklQ", “e”:“AQAB” }
如果我将令牌传递给https://www.googleapis.com/oauth2/v3/tokeninfo?id_token=TOKEN,则会进行验证,但这不是一个真正的答案,因为它们不会经常更改,而是进行额外的网络通话每次都是自找麻烦。
那么有人可以指出一个可行的例子吗?我试过phpseclib,但它从来没有验证过。在这一点上,我可能已经寻找了大约 40 个小时,而我已经束手无策了。
任何帮助表示赞赏。
我的相关代码:
$modulus = "";
$exponent = "";
$token = $_POST['token'];
$pieces = explode(".", $token);
$header = json_decode(base64_decode(str_replace(['-','_'], ['+','/'], $pieces[0])), true);
$alg = $header['alg'];
$kid = $header['kid'];
$payload = base64_decode(str_replace(['-','_'], ['+','/'], $pieces[1]));
$signature = str_replace(['-','_'], ['+','/'], $pieces[2]);
//$signature = base64_decode(str_replace(['-','_'], ['+','/'], $pieces[2]));
if (testGoogleList($alg, $kid, $modulus, $exponent))
{
echo "Found in list: kid=".$kid."\n";
echo "n: (base64URL)".$modulus."\n";
echo "e: (base64URL)".$exponent."\n";
$modulus = str_replace(['-','_'], ['+','/'], $modulus);
$exponent = str_replace(['-','_'], ['+','/'], $exponent);
echo "n: (base64)".$modulus."\n";
echo "e: (base64)".$exponent."\n";
$rsa = new Crypt_RSA();
$rsa->setHash("sha256");
$rsa->setSignatureMode(CRYPT_RSA_SIGNATURE_PKCS1);
$modulus = new Math_BigInteger($modulus, 256);
$exponent = new Math_BigInteger($exponent, 256);
echo "n: (BigInteger)".$modulus."\n";
echo "e: (BigInteger)".$exponent."\n";
$rsa->loadKey(array('n' => $modulus, 'e' => $exponent));
$rsa->setPublicKey();
$pubKey = $rsa->getPublicKey();
echo "Public Key from phpseclib\n".$pubKey."\n";
echo "--First openSSL error check--\n";
while ($msg = openssl_error_string())
echo $msg . "<br />\n";
echo "--After First Error Check, before Verify--\n";
$res = $rsa->verify($pieces[0].".".$pieces[1], $signature);
while ($msg = openssl_error_string())
echo $msg . "<br />\n";
echo "--Verify result: ".var_export($res, true)."--\n";
}
