消息：无法与Apple验证，错误：{error：invalid_client} Laravel php

Question

嗨，我试图验证苹果从我的 Laravel 登录，但我收到此错误可以帮助我，我什至包括了密钥 ID 和服务 ID 屏幕截图，但修改了它

{成功：错误，消息：无法与Apple验证，错误：{错误：invalid_client}}

我的 .env 文件

APPLE_CLIENT_ID=com.example.apple
APPLE_TEAM_ID=NR88888888
APPLE_KEY_ID=RJ85222222

这是我的函数，我剪切了 stackoverflow 函数的其余部分，不允许我放置整个函数

    function loginWithApple(Request $request) {
    try {
        $authCode = $request->input('apple_authorization_code');

                'success' => false,
                'message' => 'Authorization code is required'
            ], 400);
        }

        // Load and validate private key file
        $path = storage_path('appleKeys/applePrivateKey/AuthKey_RJ85222222.p8');
        if (!file_exists($path)) {

Answer 1

这个问题很棘手，正如here和here所示，问题实际上出在openSSL生成的签名上。您可以在那里阅读更多相关信息，但就我而言，我只使用了 Firebase JWT 库。

因此，对于 Apple Sign In，我们需要使用 ES256（带有 SHA-256 的 ECDSA）进行 JWT 签名。这是使用 firebase/php-jwt 库的更简单、更可靠的实现，它支持 ES256：

确保安装 Firebase JWT 库

作曲家需要 firebase/php-jwt

然后更新

    use Firebase\JWT\JWT;
    use Illuminate\Http\Request;
    use Illuminate\Support\Facades\Http;
    use Illuminate\Support\Facades\Log; 
    
       // YOUR PROBLEM CAN BE SOLVED HERE 

       // Create client secret JWT
            $clientSecret = JWT::encode([
                'iss' => env('APPLE_TEAM_ID'),
                'iat' => time(),
                'exp' => time() + 86400 * 180,  // 180 days
                'aud' => 'https://appleid.apple.com',
                'sub' => env('APPLE_CLIENT_ID'),
            ], $privateKey, 'ES256', env('APPLE_KEY_ID'));
    
            // Exchange auth code for tokens
            $response = Http::asForm()->post('https://appleid.apple.com/auth/token', [
                'client_id' => env('APPLE_CLIENT_ID'),
                'client_secret' => $clientSecret,
                'code' => $authCode,
                'grant_type' => 'authorization_code'
            ]);

这是一个完整的重构函数

 use Firebase\JWT\JWT;
 use Illuminate\Http\Request;
 use Illuminate\Support\Facades\Http;
 use Illuminate\Support\Facades\Log;


function loginWithApple(Request $request) {
    try {
        // Validate request
        $authCode = $request->input('apple_authorization_code');
        if (empty($authCode)) {
            return response()->json([
                'success' => false,
                'message' => 'Authorization code is required'
            ], 400);
        }

        // Load private key from Laravel storage location
        $privateKeyPath = storage_path('appleKeys/applePrivateKey/AuthKey_' . env('APPLE_KEY_ID') . '.p8');
        $privateKey = file_get_contents($privateKeyPath);
        if (!$privateKey) {
            throw new Exception('Could not read private key');
        }

        // Create client secret JWT
        $clientSecret = JWT::encode([
            'iss' => env('APPLE_TEAM_ID'),
            'iat' => time(),
            'exp' => time() + 86400 * 180,  // 180 days
            'aud' => 'https://appleid.apple.com',
            'sub' => env('APPLE_CLIENT_ID'),
        ], $privateKey, 'ES256', env('APPLE_KEY_ID'));

        // Exchange auth code for tokens
        $response = Http::asForm()->post('https://appleid.apple.com/auth/token', [
            'client_id' => env('APPLE_CLIENT_ID'),
            'client_secret' => $clientSecret,
            'code' => $authCode,
            'grant_type' => 'authorization_code'
        ]);

            return response()->json([
                'success' => false,
                'message' => 'Failed to verify with Apple',
                'error' => $response->json()
            ], 400);
        }

        // Get user data from ID token
        $data = $response->json();
        $idToken = $data['id_token'];
        $tokenParts = explode('.', $idToken);
        
        if (count($tokenParts) != 3) {
            throw new Exception('Invalid token format');
        }

        // Decode payload
        $payload = base64_decode(str_pad(strtr($tokenParts[1], '-_', '+/'), strlen($tokenParts[1]) % 4, '=', STR_PAD_RIGHT));
        $userData = json_decode($payload, true);

        if (!$userData) {
            throw new Exception('Failed to decode token payload');
        }

        // Verify token expiry
        if (time() > $userData['exp']) {
            throw new Exception('Token has expired');
        }

        // Return user data
        $user = $request->input('user') ? json_decode($request->input('user'), true) : null;
        
        return response()->json([
            'success' => true,
            'message' => 'Apple Sign In successful',
            'user_data' => [
                'apple_user_id' => $userData['sub'],
                'email' => $userData['email'] ?? null,
                'email_verified' => $userData['email_verified'] ?? false,
                'name' => $user['name'] ?? null
            ]
        ]);

    } catch (Exception $e) {
        Log::error('Apple Sign In Error', [
