Thinkphp5.1贝宝（Paypal）支付接入
最初打算用PayPal官方的API做，但是，发现回调的信息有点少，所以就改成了form提交的，这里记录一下：
1.先去PayPal官网申请账号，然后进入开发者中心https://developer.paypal.com/developer/accounts/，会看到已经创建好的测试账号，有买家的和卖家的
然后创建app,就可以看到生成的clientId和clientSecret:
然后设置 SANDBOX WEBHOOKS ,把Event types全选（免得漏掉什么），Webhook Url必须是https的，没有的可以去阿里云申请免费证书。
2.程序部分：
我用的是Thinkphp5.1版本，控制器里具体如下：
//贝宝支付
public function paypal(){
$id = input('id');
$row = db('order')->where(['id'=>$id])->find();
$baseUrl = getHostDomain();
$returnUrl = $baseUrl.config('app.paypal.returnUrl');
$notifyUrl = $baseUrl.config('app.paypal.notifyUrl');
$cancelUrl = $baseUrl.config('app.paypal.cancelUrl');
$business = config('app.paypal.business');
$paypalUrl = config('app.paypal.paypalUrl');
$this->assign('returnUrl', $returnUrl);
$this->assign('notifyUrl', $notifyUrl);
$this->assign('cancelUrl', $cancelUrl);
$this->assign('paypalUrl', $paypalUrl);
$this->assign('business', $business);
$this->assign('row', $row);
return $this->fetch();
}
模版内容如下：
<form action="{$paypalUrl}" method="POST" name="form_starPay">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="{$business}">
<input type="hidden" name="item_name" value="{$row.exhibition_title}">
<input type="hidden" name="item_number" value="{$row.order_number}">
<input type="hidden" name="amount" value="{$row.insurance_price}">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="return" value="{$returnUrl}">
<input type="hidden" name="notify_url" value="{$notifyUrl}">
<input type="hidden" name="cancel_return" value="{$cancelUrl}">
<input type="hidden" name="invoice" value="{$row.order_number}">
<input type="hidden" name="charset" value="utf-8">
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="rm" value="2">
<input type="image" name="submit" src="https://www.paypal.com/en_US/i/btn/btn_buynow_LG.gif" />
</form>
Jumping to Paypal, please wait...
<script>
function sub(){
document.form_starPay.submit();
}
onload(sub())
</script>
回调和付款结果：
/**
* @function paypalNotifyCallback
* @intro paypal回调
* @return string
*/
public function paypalNotifyCallback()
{
if(!$_POST){
die('error');
}
$post_data = $_POST;
paypalNotifyCallBackLog(json_encode($post_data));//记录日志
$post_data['cmd'] = '_notify-validate';
$url = config('app.paypal.paypalUrl');//支付异步验证地址
$res = https_request($url,$post_data);
importLog($res);//记录日志
if (!empty($res)) {
if (strcmp($res, "VERIFIED") == 0) {
if ($post_data['payment_status'] == 'Completed' || $post_data['payment_status'] == 'Pending') {
$paypalRow = db('paypal_record')->where(['invoice'=>$post_data['invoice']])->find();
$data = $post_data;
$data['payment_date'] = strtotime($data['payment_date']);
if(!$paypalRow){
db('paypal_record')->strict(false)->insertGetId($data);
}else{
db('paypal_record')->where(['invoice'=>$post_data['invoice']])->update($data);
}
//付款完成，这里修改订单状态
$data = [];
$data['status'] = 1;
$data['pay_time'] = strtotime($post_data['payment_date']);
db('order')->where(['order_number'=>$post_data['invoice']])->update($data);
$row = db('order')->where(['order_number'=>$post_data['invoice']])->find();
return 'success';
}
} elseif (strcmp($res, "INVALID") == 0) {
//未通过认证，有可能是编码错误或非法的 POST 信息
return 'fail';
}
} else {
//未通过认证，有可能是编码错误或非法的 POST 信息
return 'fail';
}
}
/**
* @function paypalResult
* @intro 贝宝支付结果
* @return string
*/
public function paypalResult()
{
$status = input('status');
$paypalRow = [];
if($status == 1){
$data = $_POST;
paypalNotifyCallBackLog(json_encode($data));//记录日志
$apiContext = paypalApiContext();
$paypalRow = db('paypal_record')->alias('p')->join('order o','p.invoice=o.order_number')->where(['p.invoice'=>$data['invoice']])->field('p.*,o.contact')->find();
if(!$paypalRow){
$status = 0;
}
}
$this->assign('status', $status);
$this->assign('paypalRow', $paypalRow);
return $this->fetch();
}
