外贸独立站商城之Stripe境外支付接口对接

外贸独立站是做外贸的公司自己开设的独立品牌商城，主要区别于商城平台如亚马逊、阿里巴巴等，优点是自己的地盘自己说了算，缺点是需要自己推广引流，适合有一定品牌的商家。
大部分外贸公司都是两者都做，从商品平台推广获客，然后把流量引入自己的品牌商城，打造自己的私域流量商城。
stripe支付公司是由一对来自爱尔兰的天才兄弟collison brothers一手创办的，他们表示随着美国大的民营金融科技公司进入小企业贷款领域，新一轮融资使其价值增加了一半以上。
klipc分析称，stripe的商业模式主要是梳理目前有的支付方式，将不同的支付方式打包成一套sdk接口，通过整体接入，降低用户的接入成本，以收取手续费或者服务盈利。目前在金融行业，很多公司已经采用了stripe的支付通道，比起传统通道，stripe效率更高，成本更低。
第一步：安装类库
composer require stripe/stripe-php
第二步后台控制器：
functioncreate(){
\stripe\stripe::setapikey($this->clientsecret);//私钥
try{
$jsonstr=file_get_contents('php://input');
$jsonobj=json_decode($jsonstr);//获取页面参数
$arr=object_array($jsonobj);//转换为数组
$order_id=$arr['items'][0]['order_id'];//订单单号
$order=db('order')->where('order_id',$order_id)->find();//查找订单
//订单是否存在和支付状态
if(empty($order)){
echo"can'tfindorder!";
exit();
}
if($order['pay_status']==20){
echo'theorderwaspaid!';
exit();
}
$request=request::instance();
$base_url=$request->domain();//获取网址
$time=time();
//判断支付订单是不是已经生成
if(!$order['stripe_pay']||$time-$order['stripe_time']>30*60){
$currency_list=exchangeratemodel::getfront();
$currency=$currency_list['code'];
$total_amount_currency=$order['pay_price'];
$paymentintent=\stripe\paymentintent::create([
'amount'=>$total_amount_currency*100,//订单金额
'currency'=>$currency,
'automatic_payment_methods'=>[
'enabled'=>true,
],
]);
$output=[
'clientsecret'=>$paymentintent->client_secret,
];
$transaction=explode('_secret_',$paymentintent->client_secret);//记录生成的支付单号，单号后面会加‘单号_secret_安全码’
$transaction_id=$transaction[0];
db('order')->where('order_id',$order_id)->update(['stripe_pay'=>$paymentintent->client_secret,'stripe_time'=>$time,'transaction_id'=>$transaction_id]);//记录单号
}else{
$output=[
'clientsecret'=>$order['stripe_pay'],
];
}
//createapaymentintentwithamountandcurrency
echojson_encode($output);
}catch(error$e){
http_response_code(500);
echojson_encode(['error'=>$e->getmessage()]);
}
}

在平台付款可以看到支付信息
四，获取支付状态：
webhooks
添加回调地址和事件
charge.succeeded-支付成功后
需要密钥
五、获取回调信息，控制器
publicfunctioncallback()
{
$endpoint_secret='密钥';//;
$payload=@file_get_contents('php://input');
$sig_header=$_server['http_stripe_signature'];
$event=null;
if($payload){
try{
$event=\stripe\webhook::constructevent(
$payload,$sig_header,$endpoint_secret
);
}catch(\stripe\exception\signatureverificationexception$e){
//invalidsignature
http_response_code(400);
exit();
}
}
$log_name="notify_url.log";
$this->log_result($log_name,'pay-start|--'.$event->data->object->paymentintent.'--|');
//handletheevent
switch($event->type){
case'charge.succeeded':
$paymentintent=$event->data->object;
//$payment=json_decode($paymentintent);
$payid=$paymentintent->payment_intent;
$order_no=db('order')->where('transaction_id',$payid)->value('order_no');
try{
$total_money=$event->amount/100;
//实例化订单模型
$model=$this->getordermodel($order_no,10);
//订单信息
$order=$model->getorderinfo();
if(empty($order)){
echo'ordernotexist';
}
$update_data['transaction_id']=$payid;
$status=$model->onpaysuccess(20,$update_data);
$this->log_result($log_name,'order_no:'.$order_no.'pay|--'.$paymentintent->payment_intent.'--|'.'status:'.$status);
if($status==false){
echo$model->geterror();
}
}catch(exception$e){
$this->error('payerror!','home/member/order');
//echo$e.',支付失败，支付id【'.$paymentid.'】,支付人id【'.$payerid.'】';
//exit();
}
break;
case'charge.attached':
$paymentmethod=$event->data->object;
$this->log_result($log_name,'pay-attached|--'.$event->type.'--|');
break;
//...handleothereventtypes
default:
$this->log_result($log_name,'pay-fail|--'.$event->type.'--|');
echo'receivedunknowneventtype'.$event->type;
}
}
