Blog Traffic to Official Account Auto-Generated Verification Code: WeChat Official Platform Verification Code View Plugin

Previously, Naiba shared3 Methods to Implement Blog to Official Account Traffic, which included using a plugin that replies with keywords to obtain a password. However, the verification code for that plugin was manually entered by the site admin. The one recommended today automatically generates and retrieves verification codes, enabling automatic verification code rotation for traffic generation.Plugin code is as follows:

captcha = $wx_captcha;
	}
	private function checkSignature() {
		$signature = $_GET["signature"];
		$timestamp = $_GET["timestamp"];
		$nonce = $_GET["nonce"];
		$token = WX_TOKEN;
		$tmpArr = array($token, $timestamp, $nonce);
		sort($tmpArr, SORT_STRING);
		$tmpStr = implode($tmpArr);
		$tmpStr = sha1($tmpStr);
		if ($tmpStr == $signature)
		            return true; else
		            return false;
	}
	protected function valid() {
		$echoStr = $_GET["echostr"];
		//valid signature , option
		if ($this->checkSignature()) {
			echo $echoStr;
			exit;
		} else {
			echo 'error signature';
		}
	}
	public function responseMsg() {
		//如果是验证请求,则执行签名验证并退出
		if (!empty($_GET["echostr"])) {
			$this->valid();
			//验证签名是否有效
			return;
			//返回退出
		}
		if ($_SERVER['REQUEST_METHOD'] != 'POST') {
			echo '';
			return;
		}
		//如果不是验证请求，则
		//首先，取得POST原始数据(XML格式)
		//$postData = $GLOBALS["HTTP_RAW_POST_DATA"];
		$postData = file_get_contents('php://input');
		if (empty($postData)) {
			echo '';
			return;
		}
		//如果没有POST数据，则退出
		if (!empty($postData)) {
			//解析POST数据(XML格式)
			$object = simplexml_load_string($postData, 'SimpleXMLElement', LIBXML_NOCDATA);
			$messgeType = trim($object->MsgType);//取得消息类型
			$this->fromUser = "" . $object->FromUserName;
			$this->toUser = "" . $object->ToUserName;
			$keyword = trim($object->Content);
			if( $messgeType == 'text' && $keyword == '验证码') {
				$response_content = '您的验证码为：【'.$this->captcha.'】，验证码有效期为2分钟，请抓紧使用，过期需重新申请';
				$xmlTemplate = "
                    
                    
                    %s
                    
                    
                    %d
                    ";
				$xmlText = sprintf($xmlTemplate, $this->fromUser, $this->toUser, time(), $response_content, 0);
				echo $xmlText;
			}
		} else {
			echo "";
			exit;
		}
	}
}
