> 快速对接支付宝接口,首先您需要创建一个控制器,名称叫`Alipay.class.php`,然后保存下面的代码到文件中,命名空间需要修改成您当前实例的命名空间: ~~~ <?php namespace App\home; class Alipay { protected $appId; protected $charset; protected $returnUrl; protected $notifyUrl; //私钥值 protected $rsaPrivateKey; protected $totalFee; protected $outTradeNo; protected $orderName; public function __construct() { $this->charset = 'utf-8'; } public function setAppid($appid) { $this->appId = $appid; } public function setReturnUrl($returnUrl) { $this->returnUrl = $returnUrl; } public function setNotifyUrl($notifyUrl) { $this->notifyUrl = $notifyUrl; } public function setRsaPrivateKey($rsaPrivateKey) { $this->rsaPrivateKey = $rsaPrivateKey; } public function setTotalFee($payAmount) { $this->totalFee = $payAmount; } public function setOutTradeNo($outTradeNo) { $this->outTradeNo = $outTradeNo; } public function setOrderName($orderName) { $this->orderName = $orderName; } /** * 发起订单 * @return array */ public function doPay() { //请求参数 $requestConfigs = array( 'out_trade_no'=>$this->outTradeNo, 'product_code'=>'QUICK_WAP_WAY', 'total_amount'=>$this->totalFee, //单位 元 'subject'=>$this->orderName, //订单标题 ); $commonConfigs = array( //公共参数 'app_id' => $this->appId, 'method' => 'alipay.trade.wap.pay', //接口名称 'format' => 'JSON', 'return_url' => $this->returnUrl, 'charset'=>$this->charset, 'sign_type'=>'RSA2', 'timestamp'=>date('Y-m-d H:i:s'), 'version'=>'1.0', 'notify_url' => $this->notifyUrl, 'biz_content'=>json_encode($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) { $sHtml = "<form id='alipaysubmit' name='alipaysubmit' action='https://openapi.alipay.com/gateway.do?charset=".$this->charset."' method='POST'>"; foreach($para_temp as $key=>$val){ if (false === $this->checkEmpty($val)) { $val = str_replace("'","&apos;",$val); $sHtml.= "<input type='hidden' name='".$key."' value='".$val."'/>"; } } //submit按钮控件请不要含有name属性 $sHtml = $sHtml."<input type='submit' value='ok' style='display:none;''></form>"; $sHtml = $sHtml."<script>document.forms['alipaysubmit'].submit();</script>"; return $sHtml; } public function generateSign($params, $signType = "RSA") { return $this->sign($this->getSignContent($params), $signType); } protected function sign($data, $signType = "RSA") { $priKey=$this->rsaPrivateKey; $res = "-----BEGIN RSA PRIVATE KEY-----\n" . wordwrap($priKey, 64, "\n", true) . "\n-----END RSA PRIVATE KEY-----"; ($res) or die('您使用的私钥格式错误,请检查RSA私钥配置'); if ("RSA2" == $signType) { openssl_sign($data, $sign, $res, version_compare(PHP_VERSION,'5.4.0', '<') ? SHA256 : OPENSSL_ALGO_SHA256); //OPENSSL_ALGO_SHA256是php5.4.8以上版本才支持 } else { openssl_sign($data, $sign, $res); } $sign = base64_encode($sign); return $sign; } /** * 校验$value是否非空 * if not set ,return true; * if is null , return true; **/ protected function checkEmpty($value) { if (!isset($value)) return true; if ($value === null) return true; if (trim($value) === "") return true; return false; } public function getSignContent($params) { ksort($params); $stringToBeSigned = ""; $i = 0; foreach ($params as $k => $v) { if (false === $this->checkEmpty($v) && "@" != substr($v, 0, 1)) { // 转换成目标字符集 $v = $this->characet($v, $this->charset); if ($i == 0) { $stringToBeSigned .= "$k" . "=" . "$v"; } else { $stringToBeSigned .= "&" . "$k" . "=" . "$v"; } $i++; } } unset ($k, $v); return $stringToBeSigned; } /** * 转换字符集编码 * @param $data * @param $targetCharset * @return string */ function characet($data, $targetCharset) { if (!empty($data)) { $fileType = $this->charset; if (strcasecmp($fileType, $targetCharset) != 0) { $data = mb_convert_encoding($data, $targetCharset, $fileType); //$data = iconv($fileType, $targetCharset.'//IGNORE', $data); } } return $data; } } ~~~ ### 使用: > 然后在把下面的方法粘贴到您的控制器里面,在需要调用的地方直接通过$this->alipays('appid','跳转url','通知url','订单号','支付金额','RSA2','私钥')`,注意使用要修改好参数即可 ~~~ /** * 支付宝付款 * @param $appid * @param $returnUrl string 支付成功跳转的URL * @param $notifyUrl string 支付成功异步通知的URL * @param $outTradeNo string 订单号 * @param $payAmount string 支付金额 * @param $signType string 签名类型 * @param $rsaPrivateKey string 支付宝私钥 */ public function alipays($appid, $returnUrl, $notifyUrl, $outTradeNo, $payAmount, $signType='RSA2', $rsaPrivateKey) { header('Content-type:text/html; Charset=utf-8'); $orderName = '商品购买订单付款'; //订单标题 /*** 配置结束 ***/ $aliPay = new Alipay(); $aliPay->setAppid($appid); $aliPay->setReturnUrl($returnUrl); $aliPay->setNotifyUrl($notifyUrl); $aliPay->setRsaPrivateKey($rsaPrivateKey); $aliPay->setTotalFee($payAmount); $aliPay->setOutTradeNo($outTradeNo); $aliPay->setOrderName($orderName); $sHtml = $aliPay->doPay(); echo $sHtml; } ~~~
