实现步骤：

1.先在前端获取fromid，openid

2.将fromid，openid存入对应用户的数据库

3.下来就是写模板消息，查询对应用户的fromid和openid，将key值对应写上

4.获取access_token，保存时间7200

5.调用模板方法即可

6.模板需要在公众号里边设置，每项就是一个key

前端：

    <form bindsubmit="submitForm" report-submit >
      <button class="m-publicBtn" wx:if="{{isPreview}}" class="save_btn" bindtap='onTapPublish' form-type="submit">发布</button>
    </form>

js获取fromid存数据库

    // 存储fromId
    submitForm:function(e){
      console.log(e)
      var formid = e.detail.formId;
      var userId = wx.getStorageSync('user_id');
      wxb.Post('/api/automatic.Msg/formId', {
        formid: formid,
        userId: userId
      }, function (data) {

      });
    },

模板消息代码：

// 模板消息
    public function temMsg()
    {
        $userId = $this->request->param('userId');
        $user = new AutomaticModel();
        $userData = $user->where([
            'id'=>$userId
        ])->find();

        $formid = $userData['fromId'] ;
        //进入小程序的页面
        $page = 'pages/index/index';
        //openid
        $openid = $userData['openid'];

        if(!$openid||!$formid)die('failed!');
        if($userData['examine'] == 2){
            $key1 = '审核成功';//发送的消息
        }else{
            $key1 = '审核失败';//发送的消息
        }

        $key2 = date('Y-m-d H-i-s',time());
        $key3 = '13020733815';

        $access_token = $this->returnAssKey();
        $url = 'https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token='.$access_token;
        $data = array(//这里一定要按照微信给的格式
            "touser"=>$openid,
            "template_id"=>'模板id',

        // if($res){
        //     echo json_encode(array('state'=>4,'msg'=>$res));
        // }else{
        //     echo json_encode(array('state'=>5,'msg'=>$res));
        // }

    }
