使用 Apple Java User Verification 登录
2022-09-03 12:28:55
我已经实现了新的Apple功能“使用Apple登录”的应用程序端，但我无法在后端使用授权代码进行验证。我的后端是用java编写的，我无法生成JWT并与Apple服务器通信。
答案 1
首先 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此密钥。您无法再次下载此密钥，因此请将其保存在安全的地方，并且不要与他人共享。此外，此处显示的密钥 ID 请注意此内容，稍后需要用到它。您还需要团队 ID。如果你不知道它，它写在页面的右上角，如YOURDNAME - XX0XX00XXX。
您基本上将遵循以下步骤。
1.从您的密钥生成 JWT
2.使用令牌发送身份验证代码
3.解码响应
同时使用 Web 和移动设备的更新
如果您想使用Apple登录网络，则需要执行其他几个步骤。
4. 为网站添加新的标识符
转到 developer.apple.com ->证书，标识符和配置文件 ->标识符。通过单击加号按钮注册新标识符。选择“服务 ID”并继续。提供说明和标识符。标识符必须是唯一的，并且与您的捆绑 ID 不同（例如，您可以使用 com.your.bundle.id.web）。单击继续单击注册。然后选择“服务 ID”（它位于右上角的搜索图标附近），下面列出的新创建的服务 ID 单击它并
启用“使用 Apple 登录”复选框。然后，您需要配置您的域。提供您的域名并返回网址。
对于Web，如果您忘记传递有效的redirect_url或尝试多次使用相同的authorization_code，则可能会遇到invalid_grant错误。
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 String WEB_CLIENT_ID = "com.your.bundle.id.web";
private static String WEB_REDIRECT_URL = "https://bundle.your.com/";
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;
}
private static String generateWebJWT() throws Exception {
String token = Jwts.builder()
.setHeaderParam(JwsHeader.KEY_ID, KEY_ID)
.setIssuer(TEAM_ID)
.setAudience("https://appleid.apple.com")
.setSubject(WEB_CLIENT_ID)
.setExpiration(new Date(System.currentTimeMillis() + (1000 * 60 * 5)))
.setIssuedAt(new Date(System.currentTimeMillis()))
.signWith(getPrivateKey(), SignatureAlgorithm.ES256)
.compact();
return token;
}
/*
* Returns unique user id from apple
* */
public static String appleAuth(String authorizationCode, boolean forWeb) throws Exception {
HttpResponse<String> response = Unirest.post(APPLE_AUTH_URL)
.header("Content-Type", "application/x-www-form-urlencoded")
.field("client_id", forWeb ? WEB_CLIENT_ID : CLIENT_ID)
.field("client_secret", forWeb ? generateWebJWT() : generateJWT())
.field("grant_type", "authorization_code")
.field("code", authorizationCode)
.field("redirect_uri", forWeb ? WEB_REDIRECT_URL : null)
.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();
}
}
我使用BouncyCastle jjwt来生成令牌。还有unirest和gson用于休息电话。

如果您想知道，我还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;
private Boolean nonce_supported;
private Boolean email_verified;
private String email;
..getters and setters
}
答案 2
我也有一个错误，但经过一些调整，它的工作，在下面找到我的调整，注意，它在kotlin中
private suspend fun getPrivateKey(): Status {
return awaitBlocking {
val authKeyFile = appleConfig.getString("auth_private_key_file", "")
val authTokenFilePath = getDataDir()!!.resolve(authKeyFile).absolutePath

}
