使用Apple Java用户验证登录

我已经实现了新的Apple功能“使用Apple登录”的应用程序端，但是我无法在后端使用AuthorizationCode进行验证。我的后端是用Java编写的，我无法生成JWT并与Apple服务器通信。

回答：

首先进入developer.apple.com->证书，标识符和配置文件->密钥。为Apple登录生成密钥并下载该密钥。您无法再次下载此密钥，因此请将其保存在安全的地方，不要与他人共享。另外，此处显示的“密钥ID”也要注意这一点，以后将需要它。您还需要团队ID。如果您不知道，它会写在页面的右上角，例如YOURNAME-

XX0XX00XXX。

您将基本上遵循这些步骤。

1，通过密钥生成JWT

2.使用令牌发送身份验证代码

3.解码响应

public class AppleLoginUtil {
private static String APPLE_AUTH_URL = "https://appleid.apple.com/auth/token";
private static String KEY_ID = "**********";
private static String TEAM_ID = "**********";
private static String CLIENT_ID = "com.your.bundle.id";
private static PrivateKey pKey;
private static PrivateKey getPrivateKey() throws Exception {
//read your key
    String path = new ClassPathResource("apple/AuthKey.p8").getFile().getAbsolutePath();
    final PEMParser pemParser = new PEMParser(new FileReader(path));
    final JcaPEMKeyConverter converter = new JcaPEMKeyConverter();
    final PrivateKeyInfo object = (PrivateKeyInfo) pemParser.readObject();
    final PrivateKey pKey = converter.getPrivateKey(object);
    return pKey;
}
private static String generateJWT() throws Exception {
    if (pKey == null) {
        pKey = getPrivateKey();
    }
    String token = Jwts.builder()
            .setHeaderParam(JwsHeader.KEY_ID, KEY_ID)
            .setIssuer(TEAM_ID)
            .setAudience("https://appleid.apple.com")
            .setSubject(CLIENT_ID)
            .setExpiration(new Date(System.currentTimeMillis() + (1000 * 60 * 5)))
            .setIssuedAt(new Date(System.currentTimeMillis()))
            .signWith(pKey, SignatureAlgorithm.ES256)
            .compact();
    return token;
}
/*
* Returns unique user id from apple
* */
public static String appleAuth(String authorizationCode) throws Exception {
    String token = generateJWT();
    HttpResponse<String> response = Unirest.post(APPLE_AUTH_URL)
            .header("Content-Type", "application/x-www-form-urlencoded")
            .field("client_id", CLIENT_ID)
            .field("client_secret", token)
            .field("grant_type", "authorization_code")
            .field("code", authorizationCode)
            .asString();
    TokenResponse tokenResponse=new Gson().fromJson(response.getBody(),TokenResponse.class);
    String idToken = tokenResponse.getId_token();
    String payload = idToken.split("\\.")[1];//0 is header we ignore it for now
    String decoded = new String(Decoders.BASE64.decode(payload));
    IdTokenPayload idTokenPayload = new Gson().fromJson(decoded,IdTokenPayload.class);
   return idTokenPayload.getSub();
}
}

我已使用BouncyCastle jjwt生成令牌。unirest和gson还提供休息电话。

如果您想知道的话，我也解析了对这些类的响应。

public class TokenResponse {
private String access_token;
private String token_type;
private Long expires_in;
private String refresh_token;
private String id_token;
..getters and setters}
public class IdTokenPayload {
private String iss;
private String aud;
private Long exp;
private Long iat;
private String sub;//users unique id
private String at_hash;
private Long auth_time;
..getters and setters}
