我已经实现了新的苹果功能“使用 Apple 登录”的应用程序端,但我无法在后端使用授权码进行验证。我的后端是用 java 编写的,我无法生成 JWT 并与 Apple 服务器通信。

首先去 developer.apple.com -> Certificates, Identifiers & Profiles -> Keys。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,不要与他人共享。此外,您在此处显示的密钥 ID 请注意这一点,稍后您将需要它。您还需要团队 ID。如果你不知道,它写在页面的右上角,如 YOURNAME - XX0XX00XXX。

您将基本上遵循这些步骤。

1.从您的密钥生成 JWT

2.使用您的令牌发送验证码

3.解码响应

使用网络和移动设备的更新

如果您想使用 Apple 登录网页版,您还需要执行几个步骤。

4. 添加新的网络标识符

转到 developer.apple.com -> 证书、标识符和配置文件 -> 标识符。单击加号按钮注册新标识符。选择服务 ID 并继续。提供描述和标识符。标识符必须是唯一的,并且与您的捆绑包 ID 不同。(例如,您可以使用 com.your.bundle.id.web)。点击继续点击注册。然后你需要配置这个服务ID。选择服务 ID(它位于搜索图标附近的右上角)您在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。然后你需要配置你的域。提供您的域名并返回网址。

如果您忘记传递有效的redirect_url或尝试多次使用相同的authorization_code,您可能会收到invalid_grant错误。

    /*

        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
}

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
