php支付寶系列之電腦網(wǎng)站支付

 更新時(shí)間：2018年05月30日 11:51:11   作者：織夢(mèng)貓2  
這篇文章主要為大家詳細(xì)介紹了php支付寶系列之電腦網(wǎng)站支付，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

網(wǎng)上的很多PHP支付寶支付接入教程都頗為復(fù)雜，且需要配置和引入較多的文件，本人通過(guò)整理后給出一個(gè)單文件版的，希望可以給各位想接入支付寶支付的帶來(lái)些許幫助和借鑒意義。

一個(gè)PHP文件搞定支付寶系列

一個(gè)PHP文件搞定微信支付系列

環(huán)境依賴

PHP5.0以上，且需要開(kāi)啟CURL服務(wù)、SSL服務(wù)。

注意事項(xiàng)

1.文件開(kāi)頭的配置信息必須完善
2.商戶私鑰需填寫(xiě)對(duì)應(yīng)簽名算法類型的私鑰，如何生成密鑰參考：
2.1 生成RSA密鑰
2.2 創(chuàng)建應(yīng)用

代碼

<?php
header('Content-type:text/html; Charset=utf-8');
$appid = 'xxxxx'; //https://open.alipay.com 賬戶中心->密鑰管理->開(kāi)放平臺(tái)密鑰，填寫(xiě)添加了電腦網(wǎng)站支付的應(yīng)用的APPID
$returnUrl = 'http://www.xxx.com/alipay/return.php';   //付款成功后的同步回調(diào)地址
$notifyUrl = 'http://www.xxx.com/alipay/notify.php';   //付款成功后的異步回調(diào)地址
$outTradeNo = uniqid();   //你自己的商品訂單號(hào)
$payAmount = 0.01;     //付款金額，單位:元
$orderName = '支付測(cè)試';  //訂單標(biāo)題
$signType = 'RSA2';    //簽名算法類型，支持RSA2和RSA，推薦使用RSA2
//商戶私鑰，填寫(xiě)對(duì)應(yīng)簽名算法類型的私鑰，如何生成密鑰參考：https://docs.open.alipay.com/291/105971和https://docs.open.alipay.com/200/105310
