首先在tp5.0中的/extend中放人支付宝的sdk

然后在/application/index/controller 新建立一个php文件为Alipay.php

里面放支付宝支付和验签

<?php
namespace app\index\controller;
use think\Config;

class Alipay
{

    /*
     * 支付宝支付
     * $body            名称
     * $total_amount    价格
     * $product_code    订单号
     * $notify_url      异步回调地址
     */
    public function alipay($body, $total_amount, $product_code, $notify_url)
    {

        /**
         * 调用支付宝接口。
         */

        import('.Alipay.aop.AopClient', '', '.php');
        import('.Alipay.aop.request.AlipayTradeAppPayRequest', '', '.php');

        $aop = new \AopClient();

        $aop->gatewayUrl            = Config::get('alipay')['gatewayUrl'];
        $aop->appId                 = Config::get('alipay')['appId'];
        $aop->rsaPrivateKey         = Config::get('alipay')['rsaPrivateKey'];
        $aop->format                = Config::get('alipay')['format'];
        $aop->charset               = Config::get('alipay')['charset'];
        $aop->signType              = Config::get('alipay')['signType'];
        $aop->alipayrsaPublicKey    = Config::get('alipay')['alipayrsaPublicKey'];

        $request = new \AlipayTradeAppPayRequest();
        $arr['body']                = $body;
        $arr['subject']             = $body;
        $arr['out_trade_no']        = $product_code;
        $arr['timeout_express']     = '30m';
        $arr['total_amount']        = floatval($total_amount);
        $arr['product_code']        = 'QUICK_MSECURITY_PAY';

        $json = json_encode($arr);
        $request->setNotifyUrl($notify_url);
        $request->setBizContent($json);

        $response = $aop->sdkExecute($request);
        return $response;

    }

//验签

    public function rsaCheckV1($data)
    {
        $aop = new \AopClient();
        $aop->alipayrsaPublicKey = "支付宝公钥";
        $flag = $aop->rsaCheckV1($data, NULL, "RSA2");
        return $flag;
    }

}

在/application/config.php 里面放支付宝参数

没有公钥和私钥的可以在支付宝中https://docs.open.alipay.com/291/105971/中申请,在支付宝中只放公钥,私钥要好好保留。

'alipay'=>[
        'appId'             => 'appId',
        'gatewayUrl'        => 'https://openapi.alipay.com/gateway.do',
        'rsaPrivateKey'     => '私钥',
        'rsaPublicKey'      => '公钥',
        'seller'            => '',//邮箱
        'format'            => 'json',
        'charset'           => 'UTF-8',
        'signType'          => 'RSA2',
        'transport'         => 'http',
    ]

都准备好以后可以在/application/index/controller建立一个Payment.php 文件写逻辑了。

<?php
namespace app\index\controller;

use think\Config;
use think\Request;
use think\Db;
class Payment extends Controller
{
   
    public function payorder()
    {
       
        if (input('post.pay_type') == 'alipay') {
            
            $orderId=$this->order_number();
            $name="商品名称";
            $order_price=0.01;
            $alipay = new Alipay();
            $url ='域名'.'/index/Payment/alipay_notify.html';
            $array['aliapy'] = $alipay->alipay($name,$order_price,orderId, $url);
            if ($array) {
                $result = array('code' => 1, 'msg' => '成功', 'data' => $array);
                return json($result);
            } else {
                $result = array('code' => 0, 'msg' => '对不起请检查相关参数!');
                return json($result);
            }
        }else{
            $result = array('code' => 0, 'msg' => '缺少pay_type');
            return json($result);
        }
    }
    /*
     *回调
     */
    public function alipay_notify()
    {
       //回调回来是个数组,你们可以用var_export接受下放在文件中查看
       //把生成json后,然后ksort()排序,去除sign_type,sign,拼接成body=Hello&buyer_email=13788888888&buyer_id=2088002007013600..............这样字符串
         $alipay = new Alipay();
         //data就是字符串
         $alipay->rsaCheckV1($data);
          /**
         *  ①验签通过后核实如下参数out_trade_no、total_amount、seller_id
         *  ②修改订单表
        **/
        //打印success,应答支付宝。必须保证本界面无错误。只打印了success,否则支付宝将重复请求回调地址。
        echo 'success';

    }

    public function order_number()
    {
        static $ORDERSN = array();
       
        $ors = date('ymd') . substr(time(), -5) . substr(microtime(), 2, 5);

        if (isset($ORDERSN[$ors])) {

            $ORDERSN[$ors]++;
      
        } else {
            $ORDERSN[$ors] = 1;
        }
        return $ors . str_pad($ORDERSN[$ors], 2, '0', STR_PAD_LEFT);

    }
   
}
