DedeCMS 整合財付通支付接口完整實現代碼

編輯：PHP 綜合知識

背景

DedeCMS (織夢) 旅遊網站需接入騰訊財付通 (Tenpay) 支付。官方無現成模組，自行封裝 tenpay 類放入 include/payment/ 目錄，配合會員中心訂單流程。

核心類結構

<?php
if (!defined('DEDEINC')) exit('Request Error!');

class tenpay {
    var $dsql;
    var $mid;

    }

    // 設定回調地址（可選）
    function SetReturnUrl($url) {
        if ($url) $this->return_url = $url;
    }

    // 生成支付按鈕/表單
    function GetCode($order, $payment) {

        $body = $order['out_trade_no'];
        $bankType = 'DEFAULT';

配置步驟

將上述代碼存為 include/payment/tenpay.php。
後台 → 模組 → 支付方式 → 新增 → 選擇「財付通」，填入商戶號、密鑰、支付模式 (1 即時到帳 / 2 擔保)。
確保 data/payment/ 目錄可寫入日誌。
測試：前台下單選擇財付通 → 跳轉騰訊網關 → 支付成功 → 回調 carbuyaction.php?dopost=return&code=tenpay → 更新訂單狀態。
