之前的模板消息已經(jīng)廢棄，現(xiàn)在改為訂閱消息，訂閱消息發(fā)布前，需要用戶確認(rèn)后才能接收訂閱消息。

小程序端

index.wxml

<button bindtap="send">發(fā)送訂閱消息</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:'要使用的template_id',
          },
          header: {
            'content-type': 'application/json'
          },
          success (res) {
            if(res.data.errcode == '43101'){
              console.log("拒絕訂閱消息")
            }else if(res.data.errcode == '0'){
              console.log("發(fā)送訂閱消息")
            }else{
              console.log("未知錯誤")
            }
          }
        })
      }
    })
  }
)}

后端

curl_setopt($ch, CURLOPT_URL, 'https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token='.$access_token);

//設(shè)置要POST的數(shù)據(jù)
curl_setopt($ch, CURLOPT_POST, true);
$data = http://www.wxapp-union.com/'{

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
// 從證書中檢查SSL加密算法是否存在
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);

//獲取的信息以文件流的形式返回，而不是直接輸出
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//發(fā)起請求
$result = curl_exec($ch);
echo $result;

//關(guān)閉請求
curl_close($ch);
?>

access_token.php

<?php
// 聲明頁面header
header("Content-type:charset=utf-8");

// APPID、APPSECRET
$appid = "你的小程序APPID";
$appsecret = "你的小程序APPSECRET";

// 獲取access_token和jsapi_ticket
function getToken(){
    $file = file_get_contents("access_token.json",true);//讀取access_token.json里面的數(shù)據(jù)
    $result = json_decode($file,true);

//判斷access_token是否在有效期內(nèi)，如果在有效期則獲取緩存的access_token
//如果過期了則請求接口生成新的access_token并且緩存access_token.json
if (time() > $result['expires']){
        $data = http://www.wxapp-union.com/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'];
    }
}
 
//獲取新的access_token
function 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();
?>

邏輯

1、通過button控件出發(fā)send函數(shù)
2、send函數(shù)調(diào)用wx.requestSubscribeMessageAPI，微信允許接收訂閱消息
3、 wx.request向send.php后端請求
4、后端獲取access_token后，調(diào)用訂閱消息接口POST一段json數(shù)據(jù)即可發(fā)送訂閱消息
