同样的,我们先创建模型(Pay.php):
<?php
namespace app\index\model;
use think\Validate;
use think\Log;
class Pay extends \think\Model
{
private function _weixin_config(){//微信支付公共配置函数
define('WXPAY_APPID', "");//微信公众号APPID
define('WXPAY_MCHID', "");//微信商户号MCHID
define('WXPAY_KEY', "");//微信商户自定义32位KEY
define('WXPAY_APPSECRET', "");//微信公众号appsecret
vendor('wxpay.WxPay_Api');
vendor('wxpay.WxPay_NativePay');
}
public function weixin($data=[])
{//发起微信支付,如果成功,返回微信支付字符串,否则范围错误信息
$validate = new Validate([
['body','require','请输入订单描述'],
['attach','require','请输入订单标题'],
['out_trade_no','require|alphaNum','订单编号输入错误|订单编号输入错误'],
['total_fee','require|number|gt:0','金额输入错误|金额输入错误|金额输入错误'],
['notify_url','require','异步通知地址不为空'],
['trade_type','require|in:JSAPI,NATIVE,APP','交易类型错误'],
]);
if (!$validate->check($data)) {
return ['code'=>0,'msg'=>$validate->getError()];
}
$this->_weixin_config();
$notify = new \NativePay();
$input = new \WxPayUnifiedOrder();
$input->SetBody($data['body']);
$input->SetAttach($data['attach']);
$input->SetOut_trade_no($data['out_trade_no']);
$input->SetTotal_fee($data['total_fee']);
$input->SetTime_start($data['time_start']);
$input->SetTime_expire($data['time_expire']);
$input->SetGoods_tag($data['goods_tag']);
$input->SetNotify_url($data['notify_url']);
$input->SetTrade_type($data['trade_type']);
$input->SetProduct_id($data['product_id']);
$result = $notify->GetPayUrl($input);
if($result['return_code'] != 'SUCCESS'){
return ['code'=>0,'msg'=> $result['return_msg']];
}
if($result['result_code'] != 'SUCCESS'){
return ['code'=>0,'msg'=> $result['err_code_des']];
}
return ['code'=>1,'msg'=>$result["code_url"]];
}
public function notify_weixin($data='')
{//微信支付异步通知
if(!$data){
return false;
}
$this->_weixin_config();
$doc = new \DOMDocument();
$doc->loadXML($data);
$out_trade_no = $doc->getElementsByTagName("out_trade_no")->item(0)->nodeValue;
$transaction_id = $doc->getElementsByTagName("transaction_id")->item(0)->nodeValue;
$openid = $doc->getElementsByTagName("openid")->item(0)->nodeValue;
$input = new \WxPayOrderQuery();
$input->SetTransaction_id($transaction_id);
$result = \WxPayApi::orderQuery($input);
if(array_key_exists("return_code", $result) && array_key_exists("result_code", $result) && $result["return_code"] == "SUCCESS" && $result["result_code"] == "SUCCESS"){
// 处理支付成功后的逻辑业务
Log::init([
'type' => 'File',
'path' => LOG_PATH.'../paylog/'
]);
Log::write($result,'log');
return 'SUCCESS';
}
return false;
}
}
?>
创建好模型后,在控制器(Index.php)调用上面模型来实现微信支付功能:
<?php
namespace app\index\controller;
use app\index\model\Pay;
error_reporting(0);
class Index extends \think\Controller
{
public function weixin()
{//发起微信支付,得到微信支付字符串,直接输出字符串,在模板中通过jquery生成支付二维码
if(request()->isPost()){
$Pay = new Pay;
$result = $Pay->weixin([
'body' => input('post.body/s','','trim,strip_tags'),
'attach' => input('post.attach/s','','trim,strip_tags'),
'out_trade_no' => input('post.orderid/s','','trim,strip_tags'),
'total_fee' => input('post.total_fee/f',0,'trim,strip_tags')*100,//订单金额,单位为分,如果你的订单是100元那么此处应该为 100*100
'time_start' => date("YmdHis"),//交易开始时间
'time_expire' => date("YmdHis", time() + 604800),//一周过期
'goods_tag' => '在线充值余额',
'notify_url' => request()->domain().url('index/index/weixin_notify'),
'trade_type' => 'NATIVE',
'product_id' => rand(1,999999),
]);
if(!$result['code']){
return $this->error($result['msg']);
}
return $this->success($result['msg']);
}
$this->view->orderid = date("YmdHis").rand(100000,999999);
return $this->fetch();
}
public function weixin_notify()
{//微信订单异步通知
$notify_data = file_get_contents("php://input");//获取由微信传来的数据
if(!$notify_data){
$notify_data = $GLOBALS['HTTP_RAW_POST_DATA'] ?: '';//以防上面函数获取到的内容为空
}
if(!$notify_data){
exit('');
}
$Pay = new Pay;
$result = $Pay->notify_weixin($notify_data);//调用模型中的异步通知函数
exit($result);
}
}
在控制器中我们并没有直接生成二维码,而是把微信支付的字符串直接输出,因此我们在模板需要通过jquery.qrcode.js来将微信支付字符串转化为二维码,并展示给用户(weixin.html):
<!doctype html>
<html lang="zh-CN">
<head>
<meta charset="utf-8">

});
</script>
</body>
</html>
关于模板内容这里不做过多解释,如果不明白请下载下方DEMO文件查看(访问:域名/index/index/weixin)
由于异步通知需要在公网内执行,因此请将代码上传至服务器上测试
特别注意事项:
微信支付中需要提供签名文件,apiclient_cert.pem?和?apiclient_key.pem,这两个文件在vendor\wxpay目录下,需替换成对于微信商户的密钥文件才能成功调用微信支付。
