1、首先生成二維碼
include('phpqrcode.php');
$url_code = "";//掃碼之後的業務邏輯層$level = 0; //容錯級別$size = 9; //生成圖片的大小
$margin = 4; //二維碼周圍邊框空白區域間距值
$saveandprint = true; //是否儲存二維碼並顯示
$qrpath = ''; //二維碼圖片存放路徑
$filename = '隨機字串' .'.png';//生成的二維碼圖片名
if (is_dir($qrpath) == false) {
mkdir($qrpath, 0777, true);
}
QRcode::png($url_code

<?php require_once "jssdk.php"; $jssdk = new JSSDK（$appid,$appsecret）；$signPackage = $jssdk->GetSignPackage(); ?><!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> </head> <script src="/static/default/js/jquery1.8.3.min.js"></script> <script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script> <script type="text/javascript"> var openid = '<?php echo $openid;?>';//事先獲取到的openid wx.config({ debug: false, appId: '<?php echo $signPackage["appId"]; ?>', timestamp: <?php echo $signPackage["timestamp"]; ?>, nonceStr: '<?php echo $signPackage["nonceStr"]; ?>', signature: '<?php echo $signPackage["signature"]; ?>', jsApiList: [ 'scanQRCode' ] }); wx.ready(function () { wx.scanQRCode({ needResult: 1, desc: 'scanQRCode desc', success: function (res) { //alert(JSON.stringify(res));//走到這一步你可以看看彈出的是什麼東西 if(res.errMsg === "scanQRCode:ok"){ var url = res.resultStr+'&openid='+openid; location.href=url;} } }); }); wx.error(function (res) { alert(res.errMsg); }); </script> </html> 謝謝
