android - 无法取消华为 IAP 订阅

Question

我正在尝试 IAP 的服务器端 Canceled api，但我无法使用此 api 取消订阅。每次单击取消时，我都会收到此错误： responseCode:"6","re​​sponseMessage":"900030-authorization format invalid"

我使用的 API 是这样的： https ://subscr-dra.iap.hicloud.com/sub/applications/v2/purchases/stop

有人可以帮我解决这个问题吗？

Answer 1

The Extension of AT File is incorrect.

Authentication information is specified based on the request header. The details are as follows: App-level access token: Authorization: Basic Base64(APPAT:atvalue)

• Example: The app-level access token is thisIsAppAtValue, then APPAT:atvalue is APPAT:thisIsAppAtValue. Therefore, replace APPAT:atvalue in Base64(APPAT:atvalue) with APPAT:thisIsAppAtValue, and value QVBQQVQ6dGhpc0lzQXBwQXRWYWx1ZQ== is obtained. The value of Authorization in the request header is as follows: Basic QVBQQVQ6dGhpc0lzQXBwQXRWYWx1ZQ==

The sample code is as follows:

  /* Build Authorization in Header
     *
     * @param appAt app AccessToken
     * @return headers
     */
    public static Map<String, String> buildAuthorization(String appAt) {
        String oriString = MessageFormat.format("APPAT:{0}", appAt);
        String authorization =
            MessageFormat.format("Basic {0}", Base64.encodeBase64String(oriString.getBytes(StandardCharsets.UTF_8)));
        Map<String, String> headers = new HashMap<>();
        headers.put("Authorization", authorization);
        headers.put("Content-Type", "application/json; charset=UTF-8");
        return headers;
}

Answer 2

检查您作为授权放入标头的令牌的格式。

代码：

let oriString = 'APPAT:' + app_level_access_token;

let authorizationToken = new Buffer.from(oriString).toString('base64'); // converting the token into Base64.

现在authorizationToken，您可以在标题中使用它。

Answer 3

您收到的错误码 - 900030 表示您的签名验证数据格式无效。可能的原因有： • 请求标头中的令牌未在 Base64 模式下加密。• 字符串APPAT 未附加到访问令牌的开头以进行授权。正确的访问令牌格式为 APPAT:thisIsAppAtVaule。
