tp框架中集成支付宝的功能，将支付宝的demo例子存在到下图位置\Extend\Vendor\Alipay
生成支付订单
/**
* 支付订单
*/
public function pay() {
header("Content-Type:text/html; charset=utf-8");
$id = I('post.oid','', 'htmlspecialchars');
$DAO = M('order');
$order = $DAO->where("id=".$id)->find();
$error = "";
if(!isset($order)){
$error = "订单不存在";
}else if($order['PaymentStatus'] == 1){
$error = "此订单已经完成，无需再次支付！";
} else if($order['PaymentStatus'] == 2){
$error = "此订单已经取消，无法支付，请重新下单！";
}
if($error != ""){
$this->_FAIL("系统错误",$error,$this->getErrorLinks());
return ;
}
$payType = I('post.payType','', 'htmlspecialchars');
#支付宝
if($payType == 'alipay'){
$this->payWithAlipay($order);
}
}
支付订单提交
/**
* 以支付宝形式支付
* @param unknown_type $order
*/
private function payWithAlipay($order){ //引入支付宝相关的文件
require_once(VENDOR_PATH."Alipay/alipay.config.php");
require_once(VENDOR_PATH."Alipay/lib/alipay_submit.class.php"); //支付类型
$payment_type = "1";
//必填，不能修改
//服务器异步通知页面路径
$notify_url = C("HOST")."index.php/Alipay/notifyOnAlipay";
//页面跳转同步通知页面路径
$return_url = C("HOST")."index.php/Pay/ok";
//卖家支付宝帐户
$seller_email = $alipay_config['seller_email'];
//必填
//商户订单号, 从订单对象中获取
$out_trade_no = $order['OrderNum'];
//商户网站订单系统中唯一订单号，必填
//订单名称 $subject = "物流服务";
//必填
//付款金额
#正常金额
$price = $order['Price'];
#测试金额
#$price = 0.1; //必填
$body = $subject;
//商品展示地址
$show_url = C('HOST'); //构造要请求的参数数组，无需改动
$parameter = array(
"service" => "create_direct_pay_by_user",
"partner" => trim($alipay_config['partner']),
"payment_type" => $payment_type,
"notify_url" => $notify_url,
"return_url" => $return_url,
"seller_email" => $seller_email,
"out_trade_no" => $out_trade_no,
"subject" => $subject,
"total_fee" => $price,
"body" => $body,
"show_url" => $show_url,
"_input_charset" => trim(strtolower($alipay_config['input_charset']))
);
Log::write('支付宝订单参数：'.var_export($parameter,true),Log::DEBUG);
//建立请求
$alipaySubmit = new AlipaySubmit($alipay_config);
$html_text = $alipaySubmit->buildRequestForm($parameter,"get", "去支付");
echo $html_text;
}
支付宝回调接口
<?php
/**
* 支付宝回调接口
*/
class AlipayAction extends Action { /**
* 支付宝异步通知
*/
public function notifyOnAlipay(){
Log::write("notify: ".print_r($_REQUEST, true),Log::DEBUG);
require_once(VENDOR_PATH."Alipay/alipay.config.php");
require_once(VENDOR_PATH."Alipay/lib/alipay_notify.class.php");
$orderLogDao = M('orderlog');
//计算得出通知验证结果
$alipayNotify = new AlipayNotify($alipay_config);
$verify_result = $alipayNotify->verifyNotify();
Log::write('verify_result：'.var_export($verify_result,true),Log::DEBUG);
if($verify_result) {//验证成功
//商户订单号
$out_trade_no = $_POST['out_trade_no'];
//支付宝交易号
$trade_no = $_POST['trade_no'];
//根据订单号获取订单
$DAO = M('order');
$order = $DAO->where("OrderNum='".$out_trade_no."'")->find();
//如果订单不存在，设置为0
if(!isset($order)){
$orderId = 0;
}
else{
$orderId = $order['id'];
}
//交易状态
$trade_status = $_POST['trade_status'];
$log = "notify from Alipay, trade_status=".$trade_status." alipay sign=".$_POST['sign'].' price ='.$_POST['total_fee'] ;
$orderLog['o_id'] = $orderId;
if($_POST['trade_status'] == 'TRADE_FINISHED' || $_POST['trade_status'] == 'TRADE_SUCCESS') {
#修改订单状态
if ((float)$order['Price'] != (float)$_POST['total_fee']) {
$data['PaymentStatus'] = '2';
} else {
$data['PaymentStatus'] = '1';
}
$DAO ->where('id='.$orderId)->save($data);
}
$orderLog['pay_id'] = $trade_no;
$orderLog['pay_log'] = $log;
$orderLog['pay_type'] = 'alipay';
$orderLog['pay_result'] = 'success'; $orderLogDao->add($orderLog);
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
echo "success"; //返回成功标记给支付宝
}
else {
//验证不通过时，也记录下来
$orderLog['pay_log'] = "notify from Alipay, 但是验证不通过，sign=".$_POST['sign'];
$orderLog['o_id'] = -1;
$orderLog['pay_type'] = 'alipay';
$orderLog['pay_result'] = 'fail';
$orderLogDao->add($orderLog); //验证失败
echo "fail";
}
}
}
?>
今天在tp框架中集成支付宝功能，跳转支付宝的时候出现乱码错误。
需要设定header("Content-Type:text/html; charset=utf-8");
如果还有乱码查看日志信息 是否出现
NOTIC: [2] Cannot modify header information - headers already sent by (output started at
上面错误，删除错误文件开始的空格
