Navite支付介绍
Native支付是指商户系统按微信支付协议生成支付二维码,用户再用微信“扫一扫”完成支付的模式。适用于PC网站、实体店单品或订单、媒体广告支付等场景
1.先阅读微信支付接入前的准备文档 文档连接:Native支付接入前准备
2.php下载插件 composer require wechatpay/wechatpay
3.需要把证书文件下载下来用于签名验证。下载的签名文件有例如
4.需要用到的参数配置到env环境变量中 如下
5.代码实现
获取支付二维码链接- /**
- * 微信二维码预支付
- * @param string $total 价格
- * @param string $outTradeNo 商户订单号
- * @param int $duration 二维码有效时长 单位:秒
- * @return array 返回二维码链接
- */
- public static function wxNativePrePay(string $total, string $outTradeNo, $duration = 180)
- {
- try {
- $config = Common::get_platform_payInfo();
- $time = \time();
- $time_expire = $time + $duration;
- $rfc3339_time = date(DATE_RFC3339, $time_expire);
- $total = intval(bcmul($total, 100));
- $payInfo = [
- 'out_trade_no' => $outTradeNo,
- 'appid' => $config['appId'],
- 'description' => '支付维修费用',
- 'total' => $total,
- 'time_expire' => (string)$rfc3339_time,
- ];
- $instance = Common::wxPayObj();
- $resp = $instance
- ->chain('v3/pay/transactions/native')
- ->post(['json' => [
- 'mchid' => $config['merchantId'],
- 'out_trade_no' => $payInfo['out_trade_no'],
- 'time_expire' => $payInfo['time_expire'],
- 'appid' => $config['appId'],
- 'description' => $payInfo['description'],
- 'notify_url' => $config['notify_url'],
- 'amount' => [
- 'total' => $payInfo['total'],
- 'currency' => 'CNY'
- ],
- ]]);
- $data = [];
- $data['code'] = (int)$resp->getStatusCode();
- $data['body'] = $resp->getBody();
- return $data;
- } catch (\Exception $exception) {
- if ($exception instanceof RequestException && $exception->hasResponse()) {
- $message = "错误回复:" + $exception->getResponse() + "错误码:" + $exception->getResponse()->getStatusCode();
- +"错误原因" + $exception->getResponse()->getReasonPhrase();
- Log::info($message);
- }
- return [];
- }
- }
复制代码 common使用的方法- public static function get_platform_payInfo() {
- $data['merchantPrivateKeyFilePath'] = env('MERCHANT_FILE_PATH');
- $data['platformCertificateFilePath'] = env('PLATFORM_FILE_PATH');
- $data['merchantId'] = env('WX_MERCHANT_ID');
- $data['merchantCertificateSerial'] = env('CERTIFICATE_SERIAL');
- $data['appId'] = env('WX_APP_ID');
- $data['appSecret'] = env('WX_APP_SECRET');
- $data['notify_url'] = env('WX_NOTIFY_URL');
- $data['api_key'] = env('WX_API_KEY');
- return $data;
- }
- public static function wxPayObj()
- {
- try {
- $payInfo = self::get_platform_payInfo();
- // 从本地文件中加载「商户API私钥」,「商户API私钥」会用来生成请求的签名
- $merchantPrivateKeyInstance = Rsa::from($payInfo['merchantPrivateKeyFilePath'], Rsa::KEY_TYPE_PRIVATE);
- // 从本地文件中加载「微信支付平台证书」,用来验证微信支付应答的签名
- $platformPublicKeyInstance = Rsa::from($payInfo['platformCertificateFilePath'], Rsa::KEY_TYPE_PUBLIC);
- // 从「微信支付平台证书」中获取「证书序列号」
- $platformCertificateSerial = PemUtil::parseCertificateSerialNo($payInfo['platformCertificateFilePath']);
- // 构造一个 APIv3 客户端实例
- $instance = Builder::factory([
- 'mchid' => $payInfo['merchantId'],
- 'serial' => $payInfo['merchantCertificateSerial'],
- 'privateKey' => $merchantPrivateKeyInstance,
- 'certs' => [
- $platformCertificateSerial => $platformPublicKeyInstance,
- ],
- ]);
- return $instance;
- } catch (\Exception $e) {
- Log::info("返回微信支付对象失败", $e);
- return false;
- }
- }
