Preface

This article mainly introduces to you the relevant content about Thinkphp combined with AJAX long polling to realize PC and APP push. It is shared for your reference and study. Without further ado, Let’s take a look at the detailed introduction.

Implementing logic

After a certain operation (such as creating a new announcement), trigger the simultaneous push of messages to all users or designated users of the APP or mobile WEB.

Regardless of performance, some people will still use it. The implementation is as follows (based on Thinkphp5 message push):

PHP long polling

/*
  * long轮询 API查询接口
  */
 public function id_log()
 {
  if (request()->isPost()) {
   $id = $this->param[&#39;id&#39;];
 
   set_time_limit(0);
   $id_log = Db::name(&#39;table&#39;)->alias(&#39;c&#39;)
    ->join(&#39;table cc&#39;, &#39;c.youname=cc.youname&#39;, &#39;left&#39;)
    ->join(&#39;table a&#39;, &#39;cc.youname =a.youname &#39;, &#39;left&#39;)
    ->join(&#39;table u&#39;, &#39;c.youname =u.youname &#39;, &#39;left&#39;)
    ->field(&#39;&#39;)
    ->where(&#39;&#39;, $id)
    ->order(&#39;log_time desc&#39;)
    ->limit(1)
    ->select();
 
   while (true) {
    if ($id_log) {
     $id_log_set = Db::name(&#39;table2&#39;)
      ->where(&#39;&#39;, $id)
      ->limit(1)
      ->setField(&#39;log_flag&#39;, &#39;1&#39;);
     $this->response($id_log);
    }
    $this->wrong(404100);
    usleep(2000);
   }
 
  };
 }

Push message creation method

/**

 * @param int $log_c_id A用户ID
 * @param string $log_user B用户ID

 */
function createLog($log_c_id, $log_type, $log_content, $log_admin, $log_user,$log_status)
{
 $data = [
  &#39;log_c_id&#39; => $log_c_id,
  &#39;log_ip&#39; => get_client_ip(),
  &#39;log_admin&#39; => $log_admin,
  &#39;log_time&#39; => date("Y-m-d H:i:s", time()),
  &#39;log_url&#39; => get_url(),
  &#39;log_type&#39; => $log_type,
  &#39;log_content&#39; => $log_content,
  &#39;log_user&#39; => $log_user,
  &#39;log_status&#39;=>$log_status
 ];
 $logadd = \think\Db::name(&#39;table&#39;)->insertGetId($data);
 return $logadd;
}

Adopt data inventory message and detect and design flag Push in the form, otherwise offline messages will not be pushed. Likewise, you need to modify it into your own data structure!

AJAX long polling

 var getting = {
  url: &#39;{:url("youapi/url")}&#39;,
  dataType: &#39;json&#39;,
  success: function (res) {
   $(".count").text($(&#39;.llt&#39;).children().size());
   $(".llt").remove();
   if(res.length!=null){
    $.each(res, function (index, item) {
     $(".notification").append(&#39;<li class="llt" data-ccid="&#39; + item.id + &#39;"><a href="{:url(" rel="external nofollow" admin/carloan/edit")}?id=&#39;+item.log_c_id+&#39;"><span class="label label-info"><i class="icon-bullhorn"></i></span><span class="message">&#39; + item.u_name + &#39;：&#39; + item.log_content + &#39;</span><span class="time"><span class="liveTime">&#39; + item.log_time + &#39;</span></span></a></li>&#39;);
    });
   }else{
   }
  }
 };
 //关键在这里，Ajax定时访问服务端，不断获取数据 ，这里是1秒请求一次。
 window.setInterval(function () {
  $.ajax(getting)
 }, 1000);
