ThinkPHP框架整合微信支付之Native 扫码支付模式一(2)
以上代码对应native_pay.html页面
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8">
<title>微信安全支付</title>
</head>
<body>
<div align="center" id="qrcode">
<p >扫我，扫我</p>
</div>
<div align="center">
<a href="#" rel="external nofollow" >返回首页</a>
</div>
</body>
<script src="__PUBLIC__/js/qrcode.js"></script>
<script>
var url = "<?php echo $product_url;?>";
//参数1表示图像大小，取值范围1-10；参数2表示质量，取值范围'L','M','Q','H'
var qr = qrcode(10, 'M');
qr.addData(url);
qr.make();
var dom=document.createElement('DIV');
dom.innerHTML = qr.createImgTag();
var element=document.getElementById("qrcode");
element.appendChild(dom);
</script>
</html>
这里注意生存二维码的js地址，我放在了Public下的JS目录下
step3：扫码之后，就会提交给我们公众平台native配置的地址对应的去方法处理公众平台navtive配置：配置地址 http://您的域名/Pay/index.php/Home/WxNative/todoPost
对应的todoPost方法在控制器中：
public function todoPost()
{
//以log文件形式记录回调信息，用于调试
$log_name = __ROOT__."/Public/native_call.log";
//使用native通知接口
$nativeCall = new \NativeCall_pub();
//接收微信请求
$xml = $GLOBALS['HTTP_RAW_POST_DATA'];
log_result($log_name,"【接收到的native通知】:\n".$xml."\n");
$nativeCall->saveData($xml);
if($nativeCall->checkSign() == FALSE){
$nativeCall->setReturnParameter("return_code","FAIL");//返回状态码
$nativeCall->setReturnParameter("return_msg","签名失败");//返回信息
}
else
{
//提取product_id
$product_id = $nativeCall->getProductId();
//使用统一支付接口
$unifiedOrder = new \UnifiedOrder_pub();
//根据不同的$product_id设定对应的下单参数，此处只举例一种
switch ($product_id)
{
case C('WxPayConf_pub.APPID')."static"://与native_call_qrcode.php中的静态链接二维码对应
//设置统一支付接口参数
//设置必填参数

//自定义订单号，此处仅作举例
$timeStamp = time();
$out_trade_no = C('WxPayConf_pub.APPID').$timeStamp;
$unifiedOrder->setParameter("out_trade_no",$out_trade_no);//商户订单号 $unifiedOrder->setParameter("product_id","$product_id");//商品ID
$unifiedOrder->setParameter("total_fee","1");//总金额
$unifiedOrder->setParameter("notify_url",C('WxPayConf_pub.NOTIFY_URL'));//通知地址
$unifiedOrder->setParameter("trade_type","NATIVE");//交易类型
$unifiedOrder->setParameter("product_id",$product_id);//用户标识
//非必填参数，商户可根据实际情况选填
//$unifiedOrder->setParameter("sub_mch_id","XXXX");//子商户号

//$unifiedOrder->setParameter("time_expire","XXXX");//交易结束时间
//$unifiedOrder->setParameter("goods_tag","XXXX");//商品标记
//$unifiedOrder->setParameter("openid","XXXX");//用户标识
//获取prepay_id
$prepay_id = $unifiedOrder->getPrepayId();
//设置返回码
//设置必填参数
//appid已填,商户无需重复填写
//mch_id已填,商户无需重复填写
//noncestr已填,商户无需重复填写
//sign已填,商户无需重复填写
$nativeCall->setReturnParameter("return_code","SUCCESS");//返回状态码
$nativeCall->setReturnParameter("result_code","SUCCESS");//业务结果
$nativeCall->setReturnParameter("prepay_id",$prepay_id);//预支付ID
break;
default:
//设置返回码
//设置必填参数
//appid已填,商户无需重复填写
//mch_id已填,商户无需重复填写
//noncestr已填,商户无需重复填写
//sign已填,商户无需重复填写
$nativeCall->setReturnParameter("return_code","SUCCESS");//返回状态码
$nativeCall->setReturnParameter("result_code","FAIL");//业务结果
$nativeCall->setReturnParameter("err_code_des","此商品无效");//业务结果
break;
}
}
//将结果返回微信
$returnXml = $nativeCall->returnXml();
log_result($log_name,"【返回微信的native响应】:\n".$returnXml."\n");
echo $returnXml;
}
