微信公众号图文回复验证码并写入数据库的基本思路
接了个小活：要求公众号中用户回复1，公众号被动回复7位数验证码，同时把用户openId和验证码写入数据库
简单写了各测试demo：工具 thinkphp 订阅号子钦有话说内申请的测试账号
接口配置信息修改
Controller控制器 输入1得到被动回复验证码（里面大多数代码与标题无关，想必大家能用到，所以没有删除）

Model类
<?php namespace Home\Model; use Think\Model; class WeChatModel extends Model{ //多图文的回复微信方法 public function responseNews($postObj,$arr) { $toUser = $postObj->FromUserName; $fromUser = $postObj->ToUserName; $time = time(); $template = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <ArticleCount>".count($arr)."</ArticleCount> <Articles>"; foreach($arr as $k=>$v){ $template .="<item> <Title><![CDATA[".$v[\'title\']."]]></Title> <Description><![CDATA[".$v[\'description\']."]]></Description> <PicUrl><![CDATA[".$v[\'picUrl\']."]]></PicUrl> <Url><![CDATA[".$v[\'url\']."]]></Url> </item>"; } $template .= "</Articles> </xml>"; echo sprintf($template,$toUser,$fromUser,$time,\'news\'); } //回复单文本 public function responseText($postObj,$content){ $template = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <Content><![CDATA[%s]]></Content> </xml>"; $toUser = $postObj->FromUserName; $fromUser = $postObj->ToUserName; $time = time(); $msgType = \'text\'; echo sprintf($template,$toUser,$fromUser,$time,$msgType,$content); } //回复用户关注消息 public function responseSubscribe($postObj,$arr){ $this->responseNews($postObj,$arr); } }
7位验证的函数方法
//生成随机数,length长度 function getsRandChar($length){ $str = null; $strPol = "0123456789abcdefghijklmnopqrstuvwxyz";//不区分大小写
//$strPol = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz";//区分大小写 $max = strlen($strPol)-1; for($i=0;$i<$length;$i++){ $str.=$strPol[rand(0,$max)];//rand($min,$max)生成介于min和max两个数之间的一个随机整数 } return $str; }
