我们刚才已经生成永久的二维码了,现在我们开始让二维码如何知道是从哪里扫描进来的了,这一般都用在于让开发者们更加了解流量来源。
首先我们来设计一张表用来记录流量的来源,表如下所示:
我们还是老方法,看下手册
然后开始修改index.php文件,
<?php /** * wechat php test */ //define your token require_once "common.php"; //这里是引入curl发送函数的类 require_once ‘WeChat.class.php‘; define("TOKEN", "twgdh"); //这里让这个类继承了curl发送参数的类 class wechatCallbackapiTest extends WeChat { public function valid() { $echoStr = $_GET["echostr"]; //valid signature , option if($this->checkSignature()){ echo $echoStr; exit; } } public function responseMsg() { //get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //extract post data if (!empty($postStr)){ /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection, the best way is to check the validity of xml by yourself */ // 使用simplexml技术对xml进行解析 // libxml_disable_entity_loader(true), 是从安全性考虑,为了防止xml外部注入, //只对xml内部实体内容进行解析 libxml_disable_entity_loader(true); //加载 postStr 字符串 $postObj = simplexml_load_string($postStr, ‘SimpleXMLElement‘, LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->ToUserName; $keyword = trim($postObj->Content); $time = time(); global $tmp_arr; //当用户公众号有互动时,我们将会动hd_time字段更新 $connect = mysql_connect(‘localhost‘,‘root‘,‘root‘) or die(‘数据库链接失败‘); mysql_select_db(‘wxdb‘,$connect); mysql_query(‘set names utf8‘); $sql = "update qf_users set hd_time=‘{$time}‘ where openid=‘{$fromUsername}‘"; mysql_query($sql, $connect); //根据接收到的消息类型,来进行分支处理(switch) switch($postObj->MsgType) { case ‘event‘: if($postObj->Event == ‘subscribe‘) { $contentStr = "欢迎关注leigood微信测试号噢"; $resultStr = sprintf($tmp_arr[‘text‘], $fromUsername, $toUsername, $time, $contentStr); echo $resultStr; //当用户订阅时,根据用户的扫描情况来保存该用户 $connect = mysql_connect(‘localhost‘,‘root‘,‘root‘) or die(‘连接数据库失败‘); mysql_select_db(‘wxdb‘,$connect); mysql_query(‘set names utf8‘); //这里的EventKey是手册上告诉我们的,EventKey事件KEY值,qrscene_为前缀,后面为二维码的参数值 //EventKey也就是我们的场景值 $EventKey = $postObj->EventKey; $sql = "insert into qrcode_users (id,openid,scene_id) values(NULL,‘{$fromUsername}‘,‘{$EventKey}‘)"; mysql_query($sql); } break; case ‘text‘: //回复文本模块 //这里开始测试客服消息接口了 if(!empty($keyword)){ //将用户提交的内容入库 $connect = mysql_connect(‘localhost‘,‘root‘,‘root‘) or die(‘连接数据库失败‘); mysql_select_db(‘wxdb‘,$connect); mysql_query(‘set names utf8‘); $sql = "insert into zx_info (id,openid,zx_info) values(NULL,‘{$fromUsername}‘,‘{$keyword}‘)"; mysql_query($sql); $contentStr = ‘您的咨询消息我们已经收到,稍后将会有我们的客服代表进行回复‘; $resultStr = sprintf($tmp_arr[‘text‘], $fromUsername, $toUsername, $time, $contentStr); echo $resultStr; }else{ $contentStr = ‘您输入的格式有误‘; $resultStr = sprintf($tmp_arr[‘text‘], $fromUsername, $toUsername, $time, $contentStr); echo $resultStr; } break; case ‘image‘: //处理用户上传图片 $media_id = $postObj -> MediaId; //获取到用户上传的图片的mediaid $resultStr = sprintf($tmp_arr[‘image‘], $fromUsername, $toUsername, $time, $media_id); echo $resultStr; //将图片保存到本地服务器的文件系统 //1.先给图片创建一个名字 $image_file_name = time().‘.jpg‘; //2.获取该图片的内容 $image_file = file_get_contents($postObj->PicUrl); //3.保存到本地服务器的文件系统 //提醒:一定要保证您创建的文件夹是www用户可读可写,否则无法保存该图片到文件夹下 file_put_contents("./uploadimage/".$image_file_name,$image_file); //将图片的路径和相关信息入库 //1.创建一张表 //2.链接mysql数据库,并且添加图片信息 $connect = mysql_connect(‘localhost‘,‘root‘,‘root‘); mysql_select_db(‘wxdb‘,$connect); mysql_query(‘set names utf8‘); $media_path = "./uploadimage/".$image_file_name; //路径 $sql = "insert into keep_image_uploads (id,openid,media_id,media_path) values(NULL,‘{$fromUsername}‘,‘{$media_id}‘,‘{$media_path}‘)"; mysql_query($sql,$connect); break; case ‘voice‘: //处理用户上传语言的业务逻辑 $media_id = $postObj -> MediaId; //获取media_id的id号 $resultStr = sprintf($tmp_arr[‘voice‘], $fromUsername, $toUsername, $time, $media_id); echo $resultStr; break; case ‘location‘: //处理用户上传的地理位置信息 $Location_X = $postObj -> Location_X; //获取上传地理位置的纬度 $Location_Y = $postObj -> Location_Y; //获取上传地地理位置经度 $contentStr = "您上报的地理位置是:\n经度是:{$Location_Y} \n纬度是: {$Location_X}"; $resultStr = sprintf($tmp_arr[‘text‘], $fromUsername, $toUsername, $time, $contentStr); echo $resultStr; break; case ‘link‘: //接收并回复链接信息 //获取到用户上传的链接信息 $Title = $postObj -> Title; $Url = $postObj -> Url; $contentStr = "<a href=‘{$Url}‘>{$Title}</a>"; $resultStr = sprintf($tmp_arr[‘text‘], $fromUsername, $toUsername, $time, $contentStr); echo $resultStr; break; } }else { echo ""; exit; } } private function checkSignature() { // you must define TOKEN by yourself if (!defined("TOKEN")) { throw new Exception(‘TOKEN is not defined!‘); } $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); // use SORT_STRING rule sort($tmpArr, SORT_STRING); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } } //如果这段代码放在上面,那程序将会报错,因为继承的问题,会显示类没有找到 $wechatObj = new wechatCallbackapiTest(); //当接入成功后,请注销这句话,否则,会反复验证。 //$wechatObj->valid(); //添加响应请求的语句 $wechatObj->responseMsg(); ?>
这里已经可以插入数据库了,核心代码如下:
这里完事了,那么下一步就创建一个tj_users.php,主要让他用表格的方式显示出来,代码如下所示:
<?php $connect = mysql_connect(‘localhost‘,‘root‘,‘root‘) or die(‘数据库连接失败‘); mysql_select_db(‘wxdb‘,$connect); mysql_query(‘set names utf8‘); $sql = "select * from qrcode_users"; $res= mysql_query($sql); $row = array(); while($r = mysql_fetch_assoc($res)){ $row[] = $r; } ?> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>统计来路信息</title> </head> <body> <h1>统计来路信息</h1> <table border="1" cellpadding=‘0‘ cellspacing="0"> <tr> <th>id</th> <th>openid</th> <th>信息来路</th> </tr> <?php foreach($row as $k=>$v){ ?> <tr> <td><?php echo $v[‘id‘]; ?></td> <td><?php echo $v[‘openid‘]; ?></td> <td> <?php //这里的$sc用来接收值的 $sc=‘‘; if($v[‘scene_id‘] == ‘qrscene_10001‘){ $sc = "电视"; }else if($v[‘scene_id‘] == ‘qrscene_10002‘){ $sc = "杂志"; }else{ $sc = "其他"; } echo $sc; ?></td>; </tr> <?php } ?> </table> </body> </html>
然后在浏览器*问tj_users.php即可知道对方是通过什么方法进行扫描二维码的了。
