php支付宝系列之电脑网站支付

网上的很多PHP支付宝支付接入教程都颇为复杂，且需要配置和引入较多的文件，本人通过整理后给出一个单文件版的，希望可以给各位想接入支付宝支付的带来些许帮助和借鉴意义。

环境依赖

PHP5.0以上，且需要开启CURL服务、SSL服务。

注意事项

1.文件开头的配置信息必须完善 2.商户私钥需填写对应签名算法类型的私钥，如何生成密钥参考： 2.1 生成RSA密钥 2.2 创建应用

PHP;"> 密钥管理->开放平台密钥，填写添加了电脑网站支付的应用的APPID $returnUrl = 'http://www.xxx.com/alipay/return.PHP'; //付款成功后的同步回调地址 $notifyUrl = 'http://www.xxx.com/alipay/notify.PHP'; //付款成功后的异步回调地址 $outTradeNo = uniqid(); //你自己的商品订单号 $payAmount = 0.01; //付款金额，单位:元 $orderName = '支付测试'; //订单标题 $signType = 'RSA2'; //签名算法类型，支持RSA2和RSA，推荐使用RSA2 //商户私钥，填写对应签名算法类型的私钥，如何生成密钥参考：https://docs.open.alipay.com/291/105971和https://docs.open.alipay.com/200/105310 $saPrivateKey='MIIEpAIBAAKCAQEA1MV+OY6MvGfXPM0MkpjT+FdzGmPOvVmX2wF3gjwQpeHBEUP9jLXhVS32fZ1iXI1e7WUGQ5tvXn28P8190kpOn/c/G5t2CAksUvemvF7uJN/N3Z1HFMdt3omvCd14K05lgcFYz7Z4c+A7ZJF5bPCB6oshjjUmbCY3hibuWzX/1j8AgsoD9lLyxoFqxLj98k5ZrYIhk900gMQs/WJ3A1FC09Dln9fuhBUyjtPHaml+4w+sdkdzxPktxdFrMcI7M7rNEwg25XtST5Z49oFpE84AlXM7+oC9jYvIpTGE00WomsgtakN039ucT/59Bup6pLkO08Rv85UXbqzGTcYAhNHLfQIDAQABAoIBAQCbuP258s+j8KgB8ty5yiqRPoeaj+O2h4Txn7A02/sfPQvNtCI0wsTpT5twsihULo+EVYTxJCitUn7df2sP5pyGzTEd5njLRtNu4Zvhj+Thjf8grERiu9b4oXI/WRzjLRxzi+uREi40OK+fWi0xgxDCdROY/eNiEdJfV8zpaqsUxG7VdwZIJQ/8d3Mi31OWv30kr9jfEd15DBInGJgSqR+qwrAB4pBSMcW8hL6PYlzoPi1ygceFjRrnbefG40zt0OUPSexQIgAmFvGqxTl5xo3dFEziGHdfWYsBKZ2M8ubAe+R6LcndxI+o2Hw4TNcC1tDeNMtjw7+h9S5aef5A8uWBAoGBAPxCLWPhUHCYlIXUz0D1SoolZs9WK7Kz1YSWnzqrpegN+foS5/ji93YylGE+KL31TwbnGQLAwknwMX3qTzmkvTovmy8jevXBsCSEFm81q0wG/35e1SKkTXL66RqB2y0xFLdcF3f9s8ZiEclqkYwNSHh0nqzREfIxMMAsj+3n2vHdAoGBANftYkZYrbs4iI/ZcjmBYguYikNfNmrD+Ta6ckOGZqsHfwXJCAz1rF4/XCqVAc9nxuzJR/72qkn9z07uH6qSZCqlZDRkiiKaK2UVqFDB+0abMk/TGHXuMmdvMkyj2jEZxG2rkg0kmg4qYkkg/5tGG1On/0GeZNVPu8JpsFr1pDYhAoGBANr8pCTKC6fDfWP1C3qrtmrY7zhc6RB4d4pjq5UmP5+EypaiZQi2F/dfD1qfuIS3eURXyGmQZtoDDyPtDZvP/ImPnFs+pNbFryD0HfmrEKquhIvyzXoGQknnsgbV5iy3KCTJaII9FxzINAKzZei7+0a+jqUd1kN3Gogp50Sze2ltAoGARaM5Xpaa8RZ6dGocfI9Nn4/Ch5fdZPFvHkdjMoPV+LKiNKtw/Tz+KiclAlasDsfZT+RaY9AJe3NvuHTzoX807swIVR1Xr3EpLaCed+0XrN3AjB34dZAskU87WZw+cjdtMjFzGOoFBSyGJi+OP/WMOp6jo/YBbwoX88tCJROzsgECgYAT8pHHIyPt5Y/5pDb8EDvD3XNES1fBkfZffSoAodsrkeoKgrsKl+9M3rcGX+S9dscyoH0ur3BFTMHtIOOhC5qytt+BhMHIP5mAs4di4u/joQCWQbUyrUggVK5it+6BFgAT+jeB7zTAUtgGpTVFq3kLbV0NZ+XQyEHVlnoJnHYpQg=='; $aliPay = new AlipayService($appid,$returnUrl,$notifyUrl,$saPrivateKey); $sHtml = $aliPay->doPay($payAmount,$outTradeNo,$orderName,$notifyUrl); echo $sHtml;
