获取订阅时，Android Publisher API返回404，但它存在

Question

最近2天，我们遇到了Android Publisher API的问题，我们正在使用它来确定用户是否为应用付费。我100％肯定，该交易已付款，但API返回404，具体而言：

{ "code" : 404, "errors" : [ { "domain" : "global", "location" : "token", "locationType" : "parameter", "message" : "The purchase token was not found.", "reason" : "purchaseTokenNotFound" } ], "message" : "The purchase token was not found." }
