下载：支付SDK
将微信支付SDK放在第三方类库Vendor下面，请切记把WxPay.Config.php里面的商户信息修改为您的公众号信息，以避免造成资金的流失。
php端代码
public function pay(){ //商户基本信息,可以写死在WxPay.Config.php里面，其他详细参考WxPayConfig.php vendor('Pay.JSAPI'); $tools = new \JsApiPay(); $openid = $tools->GetOpenid(); $Out_trade_no=date('YHis').rand(100,1000); $Total_fee='测试'; $Body='啥也不说'; $Total_fee=1; $input = new \WxPayUnifiedOrder(); $input->SetBody($Body); $input->SetOut_trade_no($Out_trade_no); $input->SetTotal_fee($Total_fee); $input->SetNotify_url("http://xx.xxx.com/pay/notify.php"); $input->SetTrade_type("JSAPI"); $input->SetOpenid($openId); $order = \WxPayApi::unifiedOrder($input); $this->jsApiParameters = $tools->GetJsApiParameters($order); $this->display(); }
