對于任何一(yī)款軟件來說，支付功能都是核心的，那麽目前的主流支付接口主要是支付寶、微信和銀聯卡，而大(dà)多數開(kāi)發技術人員(yuán)對于如何調用支付寶的支付接口還存在很大(dà)的困擾，今天app開(kāi)發報價燚軒科技就來跟大(dà)家分(fēn)享一(yī)下(xià)如何正确調用支付寶支付接口的實現，代碼如下(xià)所示：

        2、判斷total_amount是否确實爲該訂單的實際金額（即商(shāng)戶訂單創建時的金額），

        3、校驗通知(zhī)中(zhōng)的seller_id（或者seller_email) 是否爲out_trade_no這筆單據的對應的操作方（有的時候，一(yī)個商(shāng)戶可能有多個seller_id/seller_email）
