创建PSD2上下文时Bunq Developer API异常

Question

在使用bunq Java SDK创建API上下文时，我得到了一个异常。我按如下方式创建API上下文：

ApiContext apiContext = ApiContext.createForPsd2(
            ApiEnvironmentType.SANDBOX,
            SecurityUtils.getCertificateFromFile("cert.pem"),
            SecurityUtils.getPrivateKeyFromFile("key.pem"),
            new Certificate[]{
                    SecurityUtils.getCertificateFromFile("cert.pem")
            },
            API_DEVICE_DESCRIPTION,
            new ArrayList<>()
);

然后得到下面的异常：

Exception in thread "main" com.bunq.sdk.exception.BadRequestException: Response id to help bunq debug: 12414de4-f961-4e52-9cfd-e6a53e602b1b.

Answer 1

这很可能是因为您正在尝试使用创建第一个APIContext时使用的相同证书/密钥对来创建另一个are。尝试生成新的证书/密钥对：

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes -subj '/CN=My App PISP AISP/C=NL'

您可能首先必须删除存储序列化APIContext的bunq.conf文件。

如果上面仍然显示相同的错误，请尝试将国家/地区代码更改为其他国家/地区(例如DE)。
