之前的模板音讯曾经废除，当初改为订阅音讯，订阅音讯公布前，须要用户确认后能力接管订阅音讯。

小程序端

index.wxml

<button bindtap="send">发送订阅音讯</button>

index.js

const app = getApp()Page({  data: {  }，send:function(){    wx.requestSubscribeMessage({        tmplIds: ['WZiCliW1zVtHXqX7dGnFNmFvxhW-wd9S_W4WfrwNvss'],        success:(res)=> {        wx.request({          url: 'https://www.xxx.com/send.php',          data: {            openid:'要推送的openid',            template_id:'要应用的template_id',          },          header: {            'content-type': 'application/json'          },          success (res) {            if(res.data.errcode == '43101'){              console.log("回绝订阅音讯")            }else if(res.data.errcode == '0'){              console.log("发送订阅音讯")            }else{              console.log("未知谬误")            }          }        })      }    })  })}

后端

<?php//设置 header header("Content-type:application/json");//接管参数$template_id = $_GET["template_id"];$openid = $_GET["openid"];//初始化 CURL$ch = curl_init();// 获取access_token// include '';require_once("access_token.php");//指标服务器地址 curl_setopt($ch, CURLOPT_URL, 'https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token='.$access_token);//设置要POST的数据curl_setopt($ch, CURLOPT_POST, true);$data = '{  "touser": $openid,  "template_id": $template_id,  "page": "pages/index/index",// 要跳转的页面  "miniprogram_state":"developer",  "lang":"zh_CN",  "data": {      "thing4": {          "value": "欢送应用专插本最火线小程序"      },      "thing5": {          "value": "小程序由公众号：广东专插本最火线开发"      }  }}';curl_setopt($ch, CURLOPT_POSTFIELDS, $data);curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");// 对认证证书起源的查看curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);// 从证书中查看SSL加密算法是否存在curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);//获取的信息以文件流的模式返回，而不是间接输入curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);//发动申请$result = curl_exec($ch);echo $result;//敞开申请curl_close($ch);?>

access_token.php

<?php// 申明页面headerheader("Content-type:charset=utf-8");// APPID、APPSECRET$appid = "你的小程序APPID";$appsecret = "你的小程序APPSECRET";// 获取access_token和jsapi_ticketfunction getToken(){    $file = file_get_contents("access_token.json",true);//读取access_token.json外面的数据    $result = json_decode($file,true);//判断access_token是否在有效期内，如果在有效期则获取缓存的access_token//如果过期了则申请接口生成新的access_token并且缓存access_token.jsonif (time() > $result['expires']){        $data = array();        $data['access_token'] = getNewToken();        $data['expires'] = time()+7000;        $jsonStr =  json_encode($data);        $fp = fopen("access_token.json", "w");        fwrite($fp, $jsonStr);        fclose($fp);        return $data['access_token'];    }else{        return $result['access_token'];    }} //获取新的access_tokenfunction getNewToken($appid,$appsecret){    global $appid;    global $appsecret;    $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$appsecret."";    $access_token_Arr =  file_get_contents($url);    $token_jsonarr = json_decode($access_token_Arr, true);    return $token_jsonarr["access_token"];}$access_token = getToken();?>

逻辑

1、通过button控件登程send函数
2、send函数调用wx.requestSubscribeMessageAPI，微信容许接管订阅音讯
3、 wx.request向send.php后端申请
4、后端获取access_token后，调用订阅音讯接口POST一段json数据即可发送订阅音讯
