无法使用$ auth-> getUser（$ uid）获取用户表单kreait / firebase-php；

Question

我有我的PHP代码，

use Kreait\Firebase\Factory;
use Kreait\Firebase\ServiceAccount;
use Firebase\Auth\Token\Exception\InvalidToken;
use Kreait\Firebase\Auth;


$serviceAccount = ServiceAccount::fromJsonFile(APP_ROOT_MAIN.'/path/to/service/ac.json'); 

$factory = (new Factory)
->withServiceAccount($serviceAccount);

$auth = $factory->createAuth();

try {
    $verifiedIdToken = $auth->verifyIdToken($token);
} catch (Exception $e) {
    echo "Failed"
}

$uid = $verifiedIdToken->getClaim('sub');
echo $uid;
$user = $auth->getUser($uid);
print_r($user);

借助上述代码，我可以获取用户的UID，但print_r（$ user）的输出如下所示

                        )

                )

我如何以这种格式打印$ user？

{
"uid": "jEazVdPDhqec0tnEOG7vM5wbDyU2",
"email": "user@domain.tld",
"emailVerified": true,
"displayName": null,
"photoUrl": null,
"phoneNumber": null,
"disabled": false,
"metadata": {
    "createdAt": "2018-02-14T15:41:32+00:00",
    "lastLoginAt": "2018-02-14T15:41:32+00:00"
},
"providerData": [
    {
        "uid": "user@domain.tld",
        "displayName": null,
        "email": "user@domain.tld",
        "photoUrl": null,
        "providerId": "password",
        "phoneNumber": null
    }
],
"passwordHash": "UkVEQUNURUQ=",


 "customClaims": null,
    "tokensValidAfterTime": "2018-02-14T15:41:32+00:00"
}

我需要使用功能$ auth-> getUser（'some-uid'）;获取用户的电子邮件ID和其他详细信息。但是我无法以上述格式获得预期的输出，但正在获取该类的对象作为输出。 请参阅：https://firebase-php.readthedocs.io/en/stable/user-management.html#user-records

Answer 1

您可以使用json_encode()获得输出：

$output = json_encode($user, \JSON_PRETTY_PRINT);

如果要访问用户记录的各个属性，则可以直接使用UserRecord对象并进行访问（请参阅https://github.com/kreait/firebase-php/blob/master/src/Firebase/Auth/UserRecord.php）

请确保使用最新版本的SDK-Kreait\Auth\User显示的print_r()对象在当前维护的4.x版本中不存在，应该返回的是UserRecord个对象。
