php支付宝系列之电脑网站支付

php  /  管理员 发布于 7年前   172

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。

一个PHP文件搞定支付宝系列

一个PHP文件搞定微信支付系列

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

代码

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,$returnUrl,$notifyUrl);echo $sHtml;class AlipayService{  protected $appId;  protected $returnUrl;  protected $notifyUrl;  protected $charset;  //私钥值  protected $rsaPrivateKey;  public function __construct($appid, $returnUrl, $notifyUrl,$saPrivateKey)  {    $this->appId = $appid;    $this->returnUrl = $returnUrl;    $this->notifyUrl = $notifyUrl;    $this->charset = 'utf8';    $this->rsaPrivateKey=$saPrivateKey;  }  /**   * 发起订单   * @param float $totalFee 收款总费用 单位元   * @param string $outTradeNo 唯一的订单号   * @param string $orderName 订单名称   * @param string $notifyUrl 支付结果通知url 不要有问号   * @param string $timestamp 订单发起时间   * @return array   */  public function doPay($totalFee, $outTradeNo, $orderName, $returnUrl,$notifyUrl)  {    //请求参数    $requestConfigs = array(      'out_trade_no'=>$outTradeNo,      'product_code'=>'FAST_INSTANT_TRADE_PAY',      'total_amount'=>$totalFee, //单位 元      'subject'=>$orderName, //订单标题    );    $commonConfigs = array(      //公共参数      'app_id' => $this->appId,      'method' => 'alipay.trade.page.pay',       //接口名称      'format' => 'JSON',      'return_url' => $returnUrl,      'charset'=>$this->charset,      'sign_type'=>'RSA2',      'timestamp'=>date('Y-m-d H:i:s'),      'version'=>'1.0',      'notify_url' => $notifyUrl,      'biz_content'=>json_encode($requestConfigs),    );    $commonConfigs["sign"] = $this->generateSign($commonConfigs, $commonConfigs['sign_type']);    return $this->buildRequestForm($commonConfigs);  }  /**   * 建立请求，以表单HTML形式构造（默认）   * @param $para_temp 请求参数数组   * @return 提交表单HTML文本   */  protected function buildRequestForm($para_temp) {    $sHtml = "
