如何在ThinkPHP应用程序中接入支付宝

// 支付宝参数配置
'alipay' => [
    'app_id' => '您的AppId',
    'ali_public_key' => '支付宝公钥',
    'private_key' => '商户私钥',
],

use think\helper\Hash;
use think\Request;

$request = Request::instance();
$data = [
    'out_trade_no' => '20180101000001', // 商户订单号
    'total_amount' => '0.01', // 订单金额
    'subject' => '测试订单', // 订单标题
    'body' => '测试订单详情', // 订单详情
];
$sign = Hash::make($data, 'md5', false); // 对订单数据进行加密

$this->assign('data', json_encode($data)); // 将订单数据传递给前端
$this->assign('sign', $sign); // 将签名传递给前端

use think\helper\Hash;
use think\Request;

$request = Request::instance();
$data = [
    'out_trade_no' => '20180101000001', // 商户订单号
    'total_amount' => '0.01', // 订单金额

$sign = Hash::make($data, 'md5', false); // 对订单数据进行加密

$this->assign('data', json_encode($data)); // 将订单数据传递给前端
$this->assign('sign', $sign); // 将签名传递给前端

<script type="text/javascript">
    // 创建form表单
