Firebase JWT: Signature verification failed

本文关键字：失败签名验证 JWT Firebase | 更新日期: 2023-09-27

我正在尝试对Firebase使用JWT身份验证，但我总是收到此错误："致命错误：未捕获的Firebase''JWT''SignatureInvalidException：签名验证失败"。

代码是这样的：

$key = "test";
$tokenId    = base64_encode(mcrypt_create_iv(32));
$issuedAt   = time();
$notBefore  = $issuedAt + 10;
$expire     = $notBefore + 60;
$serverName = $_SERVER["SERVER_NAME"];

$data = [
    'iat'  => $issuedAt,
    'jti'  => $tokenId,
    'iss'  => $serverName,
    'nbf'  => $notBefore,
    'exp'  => $expire,
    "userId"  => 1
];

$secretKey = base64_decode($key);

$jwt = 'Firebase'JWT'JWT::encode($data, $secretKey, 'HS256');
// and when I decode the tokens, I got that exception
$decoded = 'Firebase'JWT'JWT::decode($jwt, $key, array('HS256'));

我错了什么？

你不需要$secretKey或base64_decode密钥，只需执行以下操作：

$jwt = 'Firebase'JWT'JWT::encode($data, $key, 'HS256');
$decoded = 'Firebase'JWT'JWT::decode($jwt, $key, array('HS256'));
