这是网页支付接口
1、先把下载的支付宝集成包解压至protected/extensions/alipay下
2、在yii配置文件中main.php配置好相关参数：
'alipay'=>array( 'class'=>'application.extensions.alipay.Alipay', 'partner'=>'xxx', // your partner id 'key'=>'xxx', // your key 'seller_email'=>'xxx',// your email 'call_back_url'=>'http://xxx/order/backalipay',//同步回调地址 'notify_url'=>'http://xxx/order/notifyalipay', //异步通知地址，注意设置权限为Alipay可返回数据 'merchant_url'=>'http://xxx/order/', //支付完后自动跳回商户地址 ),
3、在extensions/alipay下写一个Alipay.php类
<?php
class Alipay {
private $format = "xml";
private $_input_charset = "utf-8";
private $sign_type = "MD5";
private $v = "2.0";
public $partner;
public $key;
public $merchant_url;
public $notify_url;
public $call_back_url;
public $seller_email;
public $alipay_config;
public function init()
{
require_once("alipay.config.php");
require_once("lib/alipay_notify.class.php");
require_once("lib/alipay_core.function.php");
require_once("lib/alipay_md5.function.php");
require_once("lib/alipay_submit.class.php");
$this->alipay_config = $alipay_config;
$this->alipay_config['key'] = $this->key;
$this->alipay_config['partner'] = $this->partner;
}
public function buildForm($request)
{
//构造要请求的参数数组，无需改动
$req_id = date('Ymdhis');
$req_data = '<direct_trade_create_req><notify_url>' . $this->notify_url . '</notify_url><call_back_url>' . $this->call_back_url . '</call_back_url><seller_account_name>' . $this->seller_email . '</seller_account_name><out_trade_no>' . $request->out_trade_no . '</out_trade_no><subject>' . $request->subject . '</subject><total_fee>' . $request->total_fee . '</total_fee><merchant_url>' . $this->merchant_url . '</merchant_url></direct_trade_create_req>';
$para_token = array(
"service" => "alipay.wap.trade.create.direct",
"partner" => trim($this->partner),
"key" => $this->key,
'sec_id' => $this->sign_type,
"format" => $this->format,
"v" => $this->v,
"req_id" => $req_id,
"req_data" => $req_data,
"_input_charset" => trim(strtolower($this->_input_charset))
);
//建立请求
$alipaySubmit = new AlipaySubmit($this->alipay_config);
$html_text = $alipaySubmit->buildRequestHttp($para_token);
//URLDECODE返回的信息
$html_text = urldecode($html_text);
//解析远程模拟提交后返回的信息
$para_html_text = $alipaySubmit->parseResponse($html_text);
//获取request_token
$request_token = $para_html_text['request_token'];
/**************************根据授权码token调用交易接口alipay.wap.auth.authAndExecute**************************/
//业务详细
$req_data = '<auth_and_execute_req><request_token>' . $request_token . '</request_token></auth_and_execute_req>';
//必填
//构造要请求的参数数组，无需改动
$parameter = array(
"service" => "alipay.wap.auth.authAndExecute",
"partner" => trim($this->partner),
'sec_id' => $this->sign_type,
"format" => $this->format,
"v" => $this->v,
"req_id" => $req_id,
"req_data" => $req_data,
"_input_charset" => trim(strtolower($this->_input_charset))
);
//建立请求
$alipaySubmit = new AlipaySubmit($this->alipay_config);
return $alipaySubmit->buildRequestForm($parameter,"get", "确认");
}
public function verifyNotify(){
$alipayNotify = new AlipayNotify($this->alipay_config);
return $alipayNotify->verifyNotify();
}
public function verifyReturn(){
$alipayNotify = new AlipayNotify($this->alipay_config);
return $alipayNotify->verifyReturn();
}
public function log_result($word) {
$file = Yii::getPathOfAlias('ext').DIRECTORY_SEPARATOR.'alipay'. DIRECTORY_SEPARATOR .'log_alipay.txt';
$fp = fopen($file,"a");
flock($fp, LOCK_EX) ;
fwrite($fp,$word."：执行日期：".strftime("%Y%m%d%H%I%S",time())."\t\n");
flock($fp, LOCK_UN);
fclose($fp);
}
}4、在OrderController.php中完成回调操作
public function actionAlipay(){
$uid = Yii::app()->user->id;
//相关逻辑
$this->alipayRequest($total, $order_id, $uid);
}
public function alipayRequest($total,$order_id,$uid){
$alipay = Yii::app()->alipay;
$request->out_trade_no = $order_id;
$request->subject = "订单号：" . $order_id;
$request->body = "订单金额" . $total . "元";
$request->total_fee = $total;
$form = $alipay->buildForm($request);
echo $form;
exit();
}
public function actionNotifyalipay(){
$user_id = Yii::app()->user->id;
$alipay = Yii::app()->alipay;
$verify_result = $alipay->verifyNotify();
if($verify_result) {
$doc = new DOMDocument();
$doc->loadXML($notify_data);
if( ! empty($doc->getElementsByTagName( "notify" )->item(0)->nodeValue) ) {
//商户订单号
$out_trade_no = $doc->getElementsByTagName( "out_trade_no" )->item(0)->nodeValue;
//支付宝交易号
$trade_no = $doc->getElementsByTagName( "trade_no" )->item(0)->nodeValue;
//交易状态
$trade_status = $doc->getElementsByTagName( "trade_status" )->item(0)->nodeValue;
//接口示例文件中，下面用的$_POST['trade_status']，但是我用POST获取不到值，直接用上面取出的$trade_status也可以。
if($trade_status == 'TRADE_FINISHED' || $trade_status == 'TRADE_SUCCESS') {
//判断该订单是否已处理
//处理业务逻辑
echo 'success';
}
}
}else{
echo 'fail';
}
}
/**
* 付款成功页
* @return [type] [description]
*/
public function actionBackalipay() {
$user_id = Yii::app()->user->id;
$alipay = Yii::app()->alipay;
$verify_result = $alipay->verifyReturn();
if($verify_result) {
//商户订单号
$out_trade_no = $_GET['out_trade_no'];
//支付宝交易号
$trade_no = $_GET['trade_no'];
//交易状态
$result = $_GET['result'];
//判断该订单是否已处理
//处理业务逻辑
}else {
$msg = '验证失败，稍后自动重试';
}
$this->render('backalipay',array(
'msg'=>$msg,
'order_id'=>$out_trade_no,
));
