}

代码中，

$result = $this->Ease->getChatTime($time);

$this->Ease = new Easemobs($option);

以上两行是引用环信demo方法，聊天记录，我下载的没有那个方法。所以手动补充了一个

将一下代码补充到demo里即可

function getChatTime($time){
   $url=$this->url.'chatmessages/'.$time;
   $header=array($this->getToken());
   $result=$this->postCurl($url,'',$header,"GET");
   return $result;
}
