		$useraccess_token = Db::table(&#39;Access_token&#39;)->select();
		$appid = "你的appid";
		$appsecret = "你的appsecret";
		$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";
		//判断是不是第一次获取access_token		
		if(!count($useraccess_token)){			
			$ch = curl_init();
			curl_setopt($ch, CURLOPT_URL, $url);
			curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
			curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
			$output = curl_exec($ch);
			curl_close($ch);
			$jsoninfo = json_decode($output, true);

			$data=[&#39;access_token&#39;=>$access_token,&#39;expires_time&#39;=>($jsoninfo[&#39;expires_in&#39;]+time()-200)];
			Db::table($table)->insert($data);
			return $access_token;
	}else if($useraccess_token[0][&#39;expires_time&#39;]<time()){//判断是否过期
		
			$ch = curl_init();
			curl_setopt($ch, CURLOPT_URL, $url);
			curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
			curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
			$output = curl_exec($ch);
			curl_close($ch);
			$jsoninfo = json_decode($output, true);//转换格式
			$access_token = $jsoninfo["access_token"];			
			$data=[&#39;access_token&#39;=>$access_token,&#39;expires_time&#39;=>($jsoninfo[&#39;expires_in&#39;]+time()-200)];
			Db::table($table)->where(&#39;expires_time&#39;,$useraccess_token[0][&#39;expires_time&#39;])->update($data);//更新数据库；
			return $access_token;
	}else{	
		$access_token = $useraccess_token[0][&#39;access_token&#39;];
		return $access_token;
		
	}

###Use the curl function to intercept the message sent by WeChat. Since the access_token obtained is only valid for 7200s, which is two hours, so every time the user makes an entry operation on the official account, it must be checked to see if it is It has expired. If it expires, it needs to be obtained again. The several if judgments in the picture above are used to judge. I save the access_token and time in the database, so that it can be taken out for detection every time. Of course, you can also use it from the cache. Call or put it into a file and call it from the file; ######After obtaining the access_token, obtain the user's personal information through access_token and openid, as shown below: ###

public function userinfo($openid){
		$access_token = $this->getaccss_token();
		//获取用户信息地址		
		$urlid = &#39;https://api.weixin.qq.com/cgi-bin/user/info?access_token=&#39;.$access_token.&#39;&openid=&#39;.$openid.&#39;&lang=zh_CN&#39;;
		$curl = curl_init(); // 启动一个CURL会话
		curl_setopt($curl, CURLOPT_URL, $urlid);
		curl_setopt($curl, CURLOPT_HEADER, 0);
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
		curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查
		//curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);  // 从证书中检查SSL加密算法是否存在
		$tmpInfo = curl_exec($curl);     //返回api的json对象
		//关闭URL请求
		curl_close($curl);
                $userinfo = json_decode($tmpInfo,true);			
		return $userinfo;
