Android Publisher取消订阅返回无效值错误

Question

我可以访问订阅数据没问题，如下： https://www.googleapis.com/androidpublisher/v2/applications/packageName/purchases/subscriptions/subscriptionId/tokens/token

我尝试通过在查询结尾添加“：cancel”来取消订阅 https://www.googleapis.com/androidpublisher/v2/applications/packageName/purchases/subscriptions/subscriptionId/tokens/token:cancel

返回：

Array
(
    [error] => Array
        (
            [errors] => Array
                (
                    [0] => Array
                        (
                            [domain] => global
                            [reason] => invalid
                            [message] => Invalid Value
                        )

                )

            [code] => 400
            [message] => Invalid Value
        )

)
