ThinkPHP實(shí)現(xiàn)支付寶接口功能實(shí)例
ThinkPHP實(shí)現(xiàn)支付寶接口功能的方法,實(shí)例講述了支付寶接口的下載及二次開(kāi)發(fā)方法,以及對(duì)應(yīng)的ThinkPHP開(kāi)發(fā)技巧,需要的朋友可以參考下.
最近做系統(tǒng),需要實(shí)現(xiàn)在線(xiàn)支付功能,毫不猶豫,選擇的是支付寶的接口支付功能,這里我用的是即時(shí)到帳的接口,具體實(shí)現(xiàn)的步驟如下:
一、下載支付寶接口包
下載地址:/pic/order/productDetail.htm?productId=2012111200373124&tabId=4#ps-tabinfo-hash
具體如何下載,我就不在羅嗦了～～
二、重新整理接口包文件,這一步應(yīng)該算是比較關(guān)鍵的(個(gè)人認(rèn)為),下載下來(lái)的接口包文件有很多語(yǔ)言的源碼
我們選擇 create_direct_pay_by_user-PHP-UTF-8 這個(gè)名稱(chēng)的接口文件,里面包括如下文件:
images文件里是支付寶相關(guān)的一些標(biāo)志的圖片,我們暫不管他,lib文件很重要,是整個(gè)接口的核心類(lèi)文件；
alipay.config.php是相關(guān)參數(shù)的配置文件
alipayapi.php 是支付寶接口入口文件
notify_url.php 是服務(wù)器異步通知頁(yè)面文件；
return_url.php 是頁(yè)面跳轉(zhuǎn)同步通知文件；
在ThinkPHP的框架文件下,找到Extend 進(jìn)入,再進(jìn)入Vendor,在Vendor文件夾下,新建文件夾Alipay,把支付寶作為第三方類(lèi)庫(kù)引入,然后,復(fù)制支付寶接口文件包中l(wèi)ib文件里的所有文件,一共4個(gè)文件,如下:
現(xiàn)在對(duì)以上文件進(jìn)行重命名.
alipay_core.function.php重命名為：Corefunction.php;
alipay_md5.function.php重命名為：Md5function.php；
alipay_notify.class.php重命名為：Notify.php；
alipay_submit.class.php重命名為：Submit.php；
然后,打開(kāi)Submit.php文件,把以下代碼去掉；
require_once("alipay_core.function.php");
require_once("alipay_md5.function.php");同樣,打開(kāi)Notify.php文件,把以下兩段代碼去掉require_once("alipay_core.function.php");
require_once("alipay_md5.function.php");為什么要去掉以上兩個(gè)文件中的這兩段代碼，因?yàn)樵陧?xiàng)目中調(diào)用接口文件的時(shí)候，我把所有4個(gè)核心文件都通過(guò)vendor來(lái)進(jìn)行引入。所以，這不再需要導(dǎo)入。
到此,支付寶接口包相關(guān)核心類(lèi)庫(kù)的整理基本完成�，F(xiàn)在開(kāi)始在項(xiàng)目中調(diào)用；
三、在項(xiàng)目中調(diào)用支付寶接口
調(diào)用分兩步:
1、在配置文件中Conf/Config.php文件中對(duì)支付寶相關(guān)參數(shù)進(jìn)行配置
復(fù)制代碼 代碼如下:
/pic/p>
'alipay_config'=>array(
'partner' =>'20********50', /pic/p>
'key'=>'9t***********ie',/pic/p>
'sign_type'=>strtoupper('MD5'),
'input_charset'=> strtolower('utf-8'),
'cacert'=> getcwd().'\\cacert.pem',
'transport'=> 'http',
),
/pic/p>
'alipay' =>array(
/pic/p>
'seller_email'=>'pay@xxx.com',
/pic/p>
'notify_url'=>'/pic/Pay/notifyurl',
/pic/p>
'return_url'=>'/pic/Pay/returnurl',
/pic/p>
'successpage'=>'User/myorder?ordtype=payed',
/pic/p>
'errorpage'=>'User/myorder?ordtype=unpay',
),
2、新建一個(gè)PayAction控制器代碼如下
復(fù)制代碼 代碼如下:
<?php
class PayAction extends Action{
/pic/p>
public function _initialize() {
vendor('Alipay.Corefunction');
vendor('Alipay.Md5function');
vendor('Alipay.Notify');
vendor('Alipay.Submit');
}
/pic/p>
public function doalipay(){
/pic/p>
/pic/alipay_submit.class.php");
/pic/p>
$alipay_config=C('alipay_config');
$payment_type = "1"; /pic/pic/p>
$notify_url = C('alipay.notify_url'); /pic/p>
$return_url = C('alipay.return_url'); /pic/p>
$seller_email = C('alipay.seller_email');/pic/p>
$out_trade_no = $_POST['trade_no'];/pic/p>
$subject = $_POST['ordsubject']; /pic/pic/p>
$total_fee = $_POST['ordtotal_fee']; /pic/pic/p>
$body = $_POST['ordbody']; /pic/p>
$show_url = $_POST['ordshow_url']; /pic/p>
$anti_phishing_key = "";/pic/pic/p>
$exter_invoke_ip = get_client_ip(); /pic/p>
/pic/p>
$parameter = array(
"service" => "create_direct_pay_by_user",
"partner" => trim($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" => $total_fee,
"body" => $body,
"show_url" => $show_url,
"anti_phishing_key" => $anti_phishing_key,
"exter_invoke_ip" => $exter_invoke_ip,
"_input_charset" => trim(strtolower($alipay_config['input_charset']))
);
/pic/p>
$alipaySubmit = new AlipaySubmit($alipay_config);
$html_text = $alipaySubmit->buildRequestForm($parameter,"post", "確認(rèn)");
echo $html_text;
}
function notifyurl(){
/pic/p>
/pic/alipay_notify.class.php");
/pic/p>
$alipay_config=C('alipay_config');
/pic/p>
$alipayNotify = new AlipayNotify($alipay_config);
$verify_result = $alipayNotify->verifyNotify();
if($verify_result) {
/pic/p>
/pic/p>
$out_trade_no = $_POST['out_trade_no']; /pic/p>
$trade_no = $_POST['trade_no']; /pic/p>
$trade_status = $_POST['trade_status']; /pic/p>
$total_fee = $_POST['total_fee']; /pic/p>
$notify_id = $_POST['notify_id']; /pic/p>
$notify_time = $_POST['notify_time']; /pic/p>
$buyer_email = $_POST['buyer_email']; /pic/p>
$parameter = array(
"out_trade_no" => $out_trade_no, /pic/p>
"trade_no" => $trade_no, /pic/p>
"total_fee" => $total_fee, /pic/p>
"trade_status" => $trade_status, /pic/p>
"notify_id" => $notify_id, /pic/p>
"notify_time" => $notify_time, /pic/p>
"buyer_email" => $buyer_email, /pic/p>
);
if($_POST['trade_status'] == 'TRADE_FINISHED') {
/pic/p>
}else if ($_POST['trade_status'] == 'TRADE_SUCCESS') { if(!checkorderstatus($out_trade_no)){
orderhandle($parameter);
/pic/p>
}
}
echo "success"; /pic/p>
}else {
/pic/p>
echo "fail";
}
}
function returnurl(){
/pic/p>
$alipay_config=C('alipay_config');
$alipayNotify = new AlipayNotify($alipay_config);/pic/p>
$verify_result = $alipayNotify->verifyReturn();
if($verify_result) {
/pic/p>
/pic/p>
$out_trade_no = $_GET['out_trade_no']; /pic/p>
$trade_no = $_GET['trade_no']; /pic/p>
$trade_status = $_GET['trade_status']; /pic/p>
$total_fee = $_GET['total_fee']; /pic/p>
$notify_id = $_GET['notify_id']; /pic/p>
$notify_time = $_GET['notify_time']; /pic/p>
$buyer_email = $_GET['buyer_email']; /pic/p>
$parameter = array(
"out_trade_no" => $out_trade_no, /pic/p>
"trade_no" => $trade_no, /pic/p>
"total_fee" => $total_fee, /pic/p>
"trade_status" => $trade_status, /pic/p>
"notify_id" => $notify_id, /pic/p>
"notify_time" => $notify_time, /pic/p>
"buyer_email" => $buyer_email, /pic/p>
);
if($_GET['trade_status'] == 'TRADE_FINISHED' || $_GET['trade_status'] == 'TRADE_SUCCESS') {
if(!checkorderstatus($out_trade_no)){
orderhandle($parameter); /pic/p>
}
$this->redirect(C('alipay.successpage'));/pic/p>
}else {
echo "trade_status=".$_GET['trade_status'];
$this->redirect(C('alipay.errorpage'));/pic/p>
}
}else {
/pic/p>
/pic/p>
echo "支付失��！";
}
}
}
?>
3、這里有幾個(gè)支付處理過(guò)程中需要用到的函數(shù),我把這些函數(shù)寫(xiě)到了項(xiàng)目的Common/common.php中,這樣不用手動(dòng)調(diào)用,即可直接使用這些函數(shù),代碼如下：
復(fù)制代碼 代碼如下:
/pic/p>
/pic/p>
/pic/p>
/pic/p>
function checkorderstatus($ordid){
$Ord=M('Orderlist');
$ordstatus=$Ord->where('ordid='.$ordid)->getField('ordstatus');
if($ordstatus==1){
return true;
}else{
return false;
}
}
/pic/p>
/pic/p>
function orderhandle($parameter){
$ordid=$parameter['out_trade_no'];
$data['payment_trade_no'] =$parameter['trade_no'];
$data['payment_trade_status'] =$parameter['trade_status'];
$data['payment_notify_id'] =$parameter['notify_id'];
$data['payment_notify_time'] =$parameter['notify_time'];
$data['payment_buyer_email'] =$parameter['buyer_email'];
$data['ordstatus'] =1;
$Ord=M('Orderlist');
$Ord->where('ordid='.$ordid)->save($data);
}
/pic/p>
function getordcode(){
$Ord=M('Orderlist');
$numbers = range (10,99);
shuffle ($numbers);
$code=array_slice($numbers,0,4);
$ordcode=$code[0].$code[1].$code[2].$code[3];
$oldcode=$Ord->where("ordcode='".$ordcode."'")->getField('ordcode');
if($oldcode){
getordcode();
}else{
return $ordcode;
}
}
