微信推送模板消息的PHP代码整理

最近做过一个需要推送消息的系统，就研究了一下微信的模板消息的推送。由于认证过的微信号，就用测试号做的，但是过程基本一致。

本文基于微信平台的官方文档写成，http://mp.weixin.qq.com/debug/cgi-bin/readtmpl?t=tmplmsg/faq_tmpl

首先，得在微信的后台管理中设置一下，模板消息的格式，获取到一个模板消息的id

<ol class="dp-c">
<li class="alt"><span><span>{{first.DATA}}  </span></span></li>
<li><span>被撕的人：{{name.DATA}}  </span></li>
<li class="alt"><span>被撕人的组别：{{zu.DATA}}  </span></li>
<li><span>被撕时间：{{time.DATA}}  </span></li>
<li class="alt"><span>本组剩余的人：{{remain.DATA}} </span></li>
<li><span>{{remark.DATA}} </span></li>
</ol>

这里以做的一个撕名牌的通知为例，相关参数的设置如上。生成id备用。

下面直接贴出需要调用的函数moban()  和它的辅助函数http_request()

<ol class="dp-c">
<li class="alt"><span><span>http_request(){ </span></span></li>

函数的调用需要注意几点

 1、moban()函数是需要传参的，具体传参的

<em id="__mceDel">moban($name,$zu,$remain,$openid<span>)   <br>$name 被撕的人<br>$zu   被撕的人组别<br>$remain 本组剩余的人<br>$openid 发送给哪个openid<br>传参的可以自行修改 只需要对应上函数里面模板的输出格式 <br>模板里面的appid appserect一定要填<br><br></span></em><span style="font-size: 15px;">2、数据库的一定在要在数据库里面建一个表，因为access_token的有效期只有7200s，防止它过期这里采用了数据库保存的方式，表名为tokentime，三个字段就可以了，分别是id(int) time(varchar) access_token(varchar)    //括号里面是格式，access_token字段一定要大一点<br><br>至此就可以使用自己的模板给用户发消息了，由于发送模板消息是按照openid发送的，所有需要获取用户的openid。<br>等有时间，写一下如何批量获取用户的openid，存入数据库，并发送模板消息和其他操作。</span>
