引入paypal包
composer require paypal/rest-api-sdk-php
写一个最简单的页面,我用的是laravel框架,其他的php框架类似:
支付页面 - 锐客网
@php
$price=mt_rand(1,100)/100;
$products=['鞋子', '帽子', '衣服', '华为手机', '小米手机', '变形金刚'];
$product=$products[array_rand($products)];
$quantity=mt_rand(1,3);
@endphp
client_id = config('pay.paypal.client_id');
$this->secret = config('pay.paypal.secret');
$this->paypal = new \PayPal\Rest\ApiContext(
new \PayPal\Auth\OAuthTokenCredential(
$this->client_id,
$this->secret
));
#设置日志
$this->paypal->setConfig(
array(
'log.LogEnabled' => true,
'log.FileName' => '../storage/logs/paypal.log',
'log.LogLevel' => 'DEBUG',
// 'mode' => 'live',
)
);
}public function paypalProductionPage()
{
return view('pay.paypal');
