做微信支付,需要的条件是:1、开通微信服务号,2、开通微信商户后台申请支付方式(公众号支付、H5支付、APP支付、小程序支付)
(注意微信服务号里面的配置以及商户后台 安全目录 的设置,不然即使你写的没错误,也调用不成功)
公众号h5页面写法: (购物车提交--我们上一步已经生成了订单,订单表里面已经有记录了)
order.php?act=wxpay&order_sn=888888 ($user_id可以从session获取到)
//查询订单详情 $orderInfo = orderDetailInfo($order_sn,$user_id); var_dump($orderInfo); //测试支付金额 if($user_id=="24") $orderInfo['total_fee']=0.01; //调用统一下单api的请求参数 $jsApiParameters = wxUnifiedOrder($orderInfo['order_sn'],$orderInfo['total_fee']*100); $smarty->assign('jsapiparameters',$jsApiParameters); $smarty->display('wxpay.html'); //调用微信统一下单api的js参数 function wxUnifiedOrder($order_sn,$total_fee) { require_once ROOT_PATH . "wxpay/lib/WxPay.Api.php"; require_once ROOT_PATH . "wxpay/example/WxPay.JsApiPay.php"; //require_once 'log.php'; //①、获取用户openid $tools = new JsApiPay(); $openId = $tools->GetOpenid(); //②、统一下单 $input = new WxPayUnifiedOrder(); $input->SetOpenid($openId); $input->SetBody("XXX公众号购买"); $input->SetAttach("XXX公众号购买产品$order_sn"); $input->SetOut_trade_no($order_sn); $input->SetTotal_fee($total_fee); $input->SetTime_start(date("YmdHis")); $input->SetTime_expire(date("YmdHis", time() + 600)); $input->SetGoods_tag("XXX公众号购买"); $input->SetNotify_url("http://XXX.com/wxshop/wxnotify.php"); $input->SetTrade_type("JSAPI"); $order = WxPayApi::unifiedOrder($input); //printf_info($order); $jsApiParameters = $tools->GetJsApiParameters($order); //③、在支持成功回调通知中处理成功之后的事宜,见 notify.php /** * 注意: * 1、当你的回调地址不可访问的时候,回调通知会失败,可以通过查询订单来确认支付是否成功 * 2、jsapi支付时需要填入用户openid,WxPay.JsApiPay.php中有获取openid流程 (文档可以参考微信公众平台“网页授权接口”, * 参考http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html) */ return $jsApiParameters; }
html页面(怎么调用jsapi,上一个页面的$jsApiParameters参数赋值到那块了)
<a class="next btn SEND_PAY" οnclick="callpay()" >立即支付</a> <script type="text/javascript"> //调用微信JS api 支付 function jsApiCall() { WeixinJSBridge.invoke( 'getBrandWCPayRequest', {$jsapiparameters}, function(res){ if(res.err_msg == "get_brand_wcpay_request:ok" ){ layer.open({ content: '支付成功' ,skin: 'msg' ,time: 2 //2秒后自动关闭 }); } } ); } function callpay() { if (typeof WeixinJSBridge == "undefined"){ if( document.addEventListener ){ document.addEventListener('WeixinJSBridgeReady', jsApiCall, false); }else if (document.attachEvent){ document.attachEvent('WeixinJSBridgeReady', jsApiCall); document.attachEvent('onWeixinJSBridgeReady', jsApiCall); } }else{ jsApiCall(); } } </script>
