上篇文章中鞋到了公众号发送末班消息，他是最后调用两个方法，本文章简化一下

将下面的php方法放到一个可以引入的公共类中即可

构建模板消息：

我把需要用到的模板消息 都写成一个个方法，放在公共类文件中了，可以参考一下：

    //发送模板消息给用户

    public function sendanswertpltouser($openid, $template_id, $url, $first, $keynote1, $keynote2, $keynote3, $remark)

    {

        $data        = '

           {

                     "touser":"' . $openid . '",

                     "template_id":"' . $template_id . '",

                     "url":"' . $url . '",

                     "miniprogram":{

                       "appid":"",

                       "pagepath":""

                     },

                     "data":{

                             "first": {

                                 "value":"' . $first . '",

                                 "color":"#bc723c"

                             },

                             "keyword1":{

                                 "value":"' . $keynote1 . '"

                             },

                             "keyword2": {

                                 "value":"' . $keynote2 . '"

                             },

                             "keyword3": {

                                 "value":"' . $keynote3 . '"

                             },

                             "remark":{

                                 "value":"' . $remark . '",

                                 "color":"#173177"

                             }

                     }

                 }

          ';

        $accessToken = $this->getAccessToken();

        $url         = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=" . $accessToken;

        $result      = $this->https_request($url, $data);

        return json_decode($result, true);

    }

这只是我写的其中一个下单成功的模板消息，放在common文件中了,这样基本上就完成了：

在用的时候直接调用此方法，传参即可
