首先支付宝的文档真是看得头晕眼花，摸不着北的感觉，网上百度PHP支付宝一堆都是花里胡哨的，看得一脸懵逼。所以自己整理了一下，其实也没那么复杂直接上代码：

php 电脑支付的方法：

/**

* 支付宝支付

*$order_sn 单号 $total_amount 价格

*/

public function alipay($order_sn,$total_amount)

{

require_once INCLUDES_PATH.‘class‘.DS.‘Pay‘.DS.‘mobile‘.DS.‘alipaytest/‘.‘AopClient.php‘;

$aop = new AopClient();//这个类支付宝php服务端 都要用到 (app支付服务端也要用到这个类)

$aop->gatewayUrl = ‘https://openapi.alipay.com/gateway.do‘;//支付宝网关，也就是接口地址

$aop->appId = ‘201709010........‘;//APPID

$aop->rsaPrivateKey =‘‘";//商户的私钥()

$aop->format = ‘json‘;

$aop->apiVersion = ‘1.0‘;

$aop->postCharset= ‘utf-8‘;

$aop->signType = ‘RSA2‘;

$request = new AlipayTradePagePayRequest();//支付宝电脑网站支付需要用到的类 这个类支付宝SDK可以下载

$request->setNotifyUrl(HTTP_HOST.‘pay/alipay_notify.php‘);//支付结果的异步通知回调地址

$request->setReturnUrl(HTTP_HOST.‘pay/alipay_return.php‘);//同步回调回调地址

$bizcontent = json_encode(array(

‘subject‘=>‘商品订单‘.$order_sn,

‘out_trade_no‘=>$order_sn,

‘body‘=>‘商品订单‘,

‘total_amount‘=>sprintf(‘%.2f‘,$total_amount),

‘product_code‘=>‘FAST_INSTANT_TRADE_PAY‘,//支付类型，APP和电脑支付 手机支付是不一样的 所以这个类型也是不一样的

), JSON_UNESCAPED_UNICODE);

$request->setBizContent($bizcontent);

$test = $aop->pageExecute($request,‘post‘);//支付宝返回来的地址，直接是可以跳转的

echo $test;

}

附上所需要用到的类：

只需要这三个类就好了，支付宝的sdk 满满的一堆 ，但是我们不需要那么多，需要用到类再把它抠出来就好了 好像传不了文件 有需要的可以加我QQ(1031486419)我发给你

app 支付 我们PHP 服务端的代码，其实就是生成一堆支付的参数 直接上代码了，其实和上面的电脑支付没什么区别 只不过是参数有所变动：

/**

* 生成支付宝app支付参数

* @param string $title

* @param string $order_sn

* @param float $amount

* @return string*/

public function alipay_app($title, $order_sn, $amount)

}

还是三个类

只不过这个类有所变动而已

再者多了一个应用公钥：

电脑支付是不要这个PUBLIC key的

好啦 以上就是支付宝电脑网站支付和app 支付的方法  其实手机支付也是差不多的 变得就是支付类型 和支付类

看不懂的可以加我QQ。一起探讨
