3.后端具体调用代码如下：

<?phpnamespace app\common\library;class Pay{public function wxpay($openId,$goods,$order_sn,$total_fee,$attach=''){ require_once APP_PATH."/common/library/php_sdk/lib/WxPay.Api.php"; require_once APP_PATH."/common/library/php_sdk/lib/WxPay.JsApiPay.php"; require_once APP_PATH."/common/library/php_sdk/example/log.php"; // $logHandler= new CLogFileHandler(APP_ROOT."/Api/wxpay/logs/".date('Y-m-d').'.log'); // $log = Log::Init($logHandler, 15); $tools = new \JsApiPay(); if(empty($openId)) $openId = $tools->GetOpenid(); $config = new \WxPayConfig(); $input = new \WxPayUnifiedOrder(); $input->SetBody($goods); //商品名称 $input->SetAttach($attach); //附加参数,可填可不填,填写的话,里边字符串不能出现空格 $input->SetOut_trade_no($order_sn); //订单号 $input->SetTotal_fee($total_fee * 100); //支付金额,单位:分 $input->SetTime_start(date("YmdHis")); //支付发起时间 $input->SetTime_expire(date("YmdHis", time() + 600));//支付超时 $input->SetGoods_tag("test3"); //$input->SetNotify_url("http://".$_SERVER['HTTP_HOST']."/payment.php"); //支付回调验证地址 $input->SetNotify_url("http://".$_SERVER['HTTP_HOST']."/web/payment/notify/WeixinPay/notify"); $input->SetTrade_type("JSAPI"); //支付类型 $input->SetOpenid($openId); //用户openID $order = \WxPayApi::unifiedOrder($config,$input); //统一下单 // dump($order);exit; $jsApiParameters = $tools->GetJsApiParameters($order); return $jsApiParameters;}

}

$pay = new \app\common\library\Pay(); $res = $pay->wxpay($this->openid,'开通会员',$order['order_no'],$order['money']);

4.前端js核心代码如下：

function jsApiCall(data,id) { data = JSON.parse(data); WeixinJSBridge.invoke( 'getBrandWCPayRequest', data, function(res){ WeixinJSBridge.log(res.err_msg); if(res.err_msg == "get_brand_wcpay_request:ok"){ layer.msg('支付成功', {time: 2500}, function () { location.href = "{:url('xxx/xxx')}"; }); }else if(res.err_msg == "get_brand_wcpay_request:cancel"){ layer.msg("支付取消！", {time: 1800}); }else{ layer.msg("支付失败！", {time: 1800}); } } ); } 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(); } } $('.see_price').click(function() { index = layer.load(1, {shade: [0.1,'#fff'] }); var $id = $(this).attr('name'); $.ajax({ type: 'post', //可选get url: '{:url("xxx/xxx")}', //这里是接收数据的PHP程序 data: 'id='+$id, //传给PHP的数据，多个参数用&连接 dataType: 'Json', //服务器返回的数据类型 可选XML ,Json jsonp script html text等 success: function(msg) { if (msg.code == '200') { layer.close(index); jsApiCall(msg.info); } else { layer.close(index); layer.msg(msg.message, {time: 1800}); } }, error: function() { layer.close(index); layer.msg("提交失败！", {time: 1800}); } }); });
