我已將我的網站重定向到了位於Buy Now的PayPal按鈕,但是在交易成功完成後,我應該在哪裏放置我的代碼。 有人可以幫忙嗎?我需要改變自己的待遇狀態。貝寶確認交易成功完成後

您正在傳遞SuccessUrl參數;當paypal完成時,它會發送一個通知給該頁面 - 所以你應該在你的SuccessUrl的Page_Load事件中放入代碼來解析返回的查詢參數,並且做任何你需要做的本地處理。

但是會否成功通過他觸發的bidid,以便我可以設置要支付的出價? – user3287068

,但是會否成功通過他觸發的bidid,以便我可以設置出價付款?真的我的問題是如何將已成功出價的ID傳遞給SucessUrl,以便我可以獲得出價的ID並將其狀態更改爲付費 – user3287068

您應該可以將bidid作爲參數添加到sucessurl中,所以如果你傳遞了mysuccesspage.aspx?bidid = 12345,它應該用附加的自定義參數回叫你。 –
