微信支付方法

微信支付目前支持 6 种支付方法，对应的支付 method 如下：

微信参数配置

$wechatConfig = new Config();
$wechatConfig->setAppId('xxxxxx');      // 除了小程序以外使用该APPID
$wechatConfig->setMiniAppId('xxxxxx');  // 小程序使用该APPID
$wechatConfig->setMchId('xxxxxx');
$wechatConfig->setKey('xxxxxx');
$wechatConfig->setNotifyUrl('xxxxx');
$wechatConfig->setApiClientCert('xxxxxxx');//客户端证书
$wechatConfig->setApiClientKey('xxxxxxx'); //客户端证书秘钥

由于小程序拥有独立的APPID，只需要在配置里同时配置上AppId和MiniAppId两个配置项，在支付的时候会自动选择对应的APPID来发起支付

公众号支付

$officialAccount = new OfficialAccount();
$officialAccount->setOpenid('xxxxxxx');
$officialAccount->setOutTradeNo('CN' . date('YmdHis') . rand(1000, 9999));
$officialAccount->setBody('xxxxx-测试' . $outTradeNo);
$officialAccount->setTotalFee(1);
$officialAccount->setSpbillCreateIp('xxxxx');
$pay = new \EasySwoole\Pay\Pay();
$params = $pay->weChat($wechatConfig)->officialAccount($officialAccount);

可以参考demo/wechat/index.php

在使用微信支付时，商品名称中如果出现特殊字符，如 & 请自行使用urlencode在生成签名传参时进行编码

H5支付

$wap = new \EasySwoole\Pay\WeChat\RequestBean\Wap();
$wap->setOutTradeNo('CN' . date('YmdHis') . rand(1000, 9999));
$wap->setBody('xxxxx-WAP测试' . $outTradeNo);
$wap->setTotalFee(1);
$wap->setSpbillCreateIp('xxxxx');
$pay = new \EasySwoole\Pay\Pay();
$params = $pay->weChat($wechatConfig)->wap($wap);

小程序支付

$bean = new \EasySwoole\Pay\WeChat\RequestBean\MiniProgram();
$bean->setOpenid('xxxxxxxxx');
$bean->setOutTradeNo('CN' . date('YmdHis') . rand(1000, 9999));
$bean->setBody('xxxx-测试' . $outTradeNo);
$bean->setTotalFee(1);
$bean->setSpbillCreateIp($this->request()->getHeader('x-real-ip')[0]);
$pay = new \EasySwoole\Pay\Pay();
$params = $pay->weChat($this->wechatConfig)->miniProgram($bean);

App支付

$app = new App();
$app->setNonceStr('xxxxx');
$app->setSign('xxxxx');
$app->setBody('app支付测试');
$app->setOutTradeNo(date(YmdHis).rand(1000,999));
$app->setTotalFee(1);
$app->setSpbillCreateIp('xxxx');

$pay = new \EasySwoole\Pay\Pay();
$result = $pay->weChat($wechatConfig)->app($app);

扫码支付

模式一

生成扫码链接 然后生成二维码 具体请查看demo/wechat/index.php

$biz = new Biz();
$biz->setProductId('123456789');
$biz->setTimeStamp(time());
$biz->setAppId($wechatConfig->getAppId());
$biz->setMchId($wechatConfig->getMchid());
$data = $biz->toArray();
$u = new Utility($wechatConfig);
$sign = $u->generateSign($data);
$biz->setSign($sign);
$url1 = "weixin://wxpay/bizpayurl?" . $this->ToUrlParams($biz->toArray());

扫码回调地址（ps:公众号平台设置）

 $xml = $this->request()->getBody()->__toString();
$pay = new Pay();
$data = $pay->weChat($this->wechatConfig)->verify($xml);
$bean = new \EasySwoole\Pay\WeChat\RequestBean\Scan();
$bean->setOutTradeNo('CN' . date('YmdHis') . rand(1000, 9999));
$bean->setOpenid('xxxxxx');
$bean->setProductId($data['product_id']);
$bean->setBody('xxxxxx-SCAN测试' . $outTradeNo);
$bean->setTotalFee(1);
$bean->setSpbillCreateIp($this->request()->getHeader('x-real-ip')[0]);
$response = $pay->weChat($this->wechatConfig)->scan($bean);
$nativeResponse = new NativeResponse([
    'appid' => $this->wechatConfig->getAppId(),
    'mch_id' => $this->wechatConfig->getMchId(),
    'prepay_id' => $response->getPrepayId(),
    'nonce_str' => $response->getNonceStr()]);
$u = new Utility($this->wechatConfig);
$nativeResponse->setSign($u->generateSign($nativeResponse->toArray()));
$xml = (new SplArray($nativeResponse->toArray()))->toXML();
$this->response()->write($xml);

模式二

$bean = new \EasySwoole\Pay\WeChat\RequestBean\Scan();
$bean->setOutTradeNo($outTradeNo);
$bean->setProductId('123456789');
$bean->setBody('xxxx-SCAN2测试' . $outTradeNo);
$bean->setTotalFee(1);
$bean->setSpbillCreateIp($this->request()->getHeader('x-real-ip')[0]);
$pay = new Pay();
$data = $pay->weChat($this->wechatConfig)->scan($bean);
$url2 = $data->getCodeUrl();
