摘要: 这个demo包含了获取token，绑定微信号，设置自定义菜单，响应文本和事件
这个教程的基础篇和提升篇都看完了，总感觉有点隔靴挠痒的感觉，讲的东西我都懂，没有吸收多少新鲜的知识。貌似还没有我这个一年前写的脚本好呢，估计也是照顾新人吧。期待高级篇的讲解，不过现在高级篇估计还在录制当中，所以对微信公众平台开发的学习就先到这里吧。
下面介绍一下我很久以前写的这个脚本。基本上常用的几个功能都有了，access_token的获取，用户的微信号和公司的账号的绑定，查询公司服务器上的数据，自定义表单什么。不过随着水平的提高，现在返回头来看，确实有很多的不足，比较最明显的就是token获取之后，没有保存下载，而是每一次访问都会获取一次，这个问题可以把token放入memcache中来解决。把代码贴上：
<?php //获取ACCESS_TOKEN $appid = "xxxxxxxxxxxxxxxxxxxxx"; $appsecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxx"; $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$appid}&secret={$appsecret}"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($ch); curl_close($ch); $jsoninfo = json_decode($output, true); $access_token = $jsoninfo["access_token"]; //获取ACCESS_TOKEN end //define my token define("TOKEN", "xxxxxxxxxx"); //define my ACCESS_TOKEN define("ACCESS_TOKEN",$access_token); class IndexAction extends Action { public function index(){ $this->responseMsg(); $this->createMenu(); } public function valid() { $echoStr = $_GET["echostr"]; //valid signature , option if($this->checkSignature()){ echo $echoStr; exit; } } /* description of 文本展示 @param none @return none @author act @vision */ public function responseMsg() { //获取微信发来的数据 $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //extract post data if (!empty($postStr)){ //将这个xml编程一个对象 $postObj = simplexml_load_string($postStr, ‘SimpleXMLElement‘, LIBXML_NOCDATA); $openid=$postObj->FromUserName; $openid=(string)$openid; $text_type = trim($postObj->MsgType); //获取消息类型 switch ($text_type) { case ‘text‘: $content=trim($postObj->Content); //功能：绑定用户 //微信号，公司账号内容绑定，格式： 用户名+手机号+身份证后四位 $user_info=explode(‘+‘,$content); $username=$user_info[0]; //用户提交的用户名 $phone=$user_info[1]; //提交的手机号码 $card_id=$user_info[2]; //提交的电话号码 $user_info_count=count($user_info); if( $user_info_count==3){ //如果数组的元素为三个，说明就是验证微信号 $model=new Model(); $sql="select a.user_id,a.username,b.phone,c.card_id from deayou_users as a left join deayou_users_info as b on a.user_id=b.user_id left join deayou_approve_realname as c on a.user_id=c.user_id where a.username=‘{$username}‘ and b.phone=‘{$phone}‘ and right(c.card_id,4)=‘{$card_id}‘"; $res=$model->query($sql); $cond[‘openid‘]=$openid; $is_openid=M(‘weixin_user_bind‘)->where($cond)->find(); //是否已经绑定过 if($res && $is_openid){ //此刻 说明是修改 /* 以下注释的代码不要删除，万一哪天还要改回来，删掉注释即可。 */ // $where1[‘openid‘]=array(‘eq‘,$openid);
