thinkPHP和微支付实现的微信支付插件,在微信中调用微信jssdk实现支付,这里有详细的代码和教程,具体看这里:http://vote.wucheshuedu.com/index.php?s=/Home/Article/detail/id/20.html//实现的Wxpay钩子方法 public function Wxpay($param){ require './Addons/Wxpay/WxPayPubHelper/WxPayPubHelper.php'; $jsApi = new \JsApi_pub(); //=========步骤1:网页授权获取用户openid============ if (!isset($_GET['code'])) { //触发微信返回code码 $url = $jsApi->createOauthUrlForCode(\WxPayConf_pub::JS_API_CALL_URL.'/order_id/'.$param['order_id']); Header("Location: $url"); }else { $order_id = $param['order_id']; $info = M('Order')->where('id='.$order_id)->find(); if(empty($info) || $info['is_pay'] == 1){ dump('该订单不存在或已支付'.$order_id); exit(); } $this->assign('info', $info); $a = $info['money']; $b = 100; $c = $a * $b; //获取code码,以获取openid $code = $_GET['code']; $jsApi->setCode($code); $openid = $jsApi->getOpenId(); } //=========步骤2:使用统一支付接口,获取prepay_id============ //使用统一支付接口 $unifiedOrder = new \UnifiedOrder_pub(); $unifiedOrder->setParameter("openid","$openid");//商品描述 $unifiedOrder->setParameter("body","在线预订");//商品描述 //自定义订单号,此处仅作举例 $timeStamp = time(); // $out_trade_no = \WxPayConf_pub::APPID."$timeStamp"; $out_trade_no = $info['ordersn']; $unifiedOrder->setParameter("out_trade_no", "$out_trade_no");//商户订单号 $unifiedOrder->setParameter("total_fee", "$c");//总金额 $unifiedOrder->setParameter("notify_url",\WxPayConf_pub::NOTIFY_URL.'/order_id/'.$param['order_id']);//通知地址 $unifiedOrder->setParameter("trade_type","JSAPI");//交易类型 $prepay_id = $unifiedOrder->getPrepayId(); //=========步骤3:使用jsapi调起支付============ $jsApi->setPrepayId($prepay_id); $jsApiParameters = $jsApi->getParameters(); $this->assign('jsApiParameters', $jsApiParameters); $this->display('pay'); }
