从百度百科抓取内容 <?php //echo getbaike('马化腾'); //输出 http://baike.baidu.com/view/1466380.htm function getEncyclopediaInfo($name){ $name_gbk = iconv('utf-8', 'gbk', $name); //将字符转换成GBK编码,若文件为GBK编码可去掉本行 $encode = urlencode($name_gbk); //对字符进行URL编码 $url = 'http://baike.baidu.com/list-php/dispose/searchword.php?word=' .$encode. '&pic=1'; $get_contents = httpGetRequest_baike($url); //获取跳转页内容 $get_contents_gbk = iconv('gbk', 'utf-8', $get_contents); //将获取的网页转换成UTF-8编码,若文件为GBK编码可去掉本行 preg_match("/URL=(\S+)'>/s", $get_contents_gbk, $out); //获取跳转后URL $real_link = 'http://baike.baidu.com' .$out[1]; $get_contents2 = httpGetRequest_baike($real_link); //获取跳转页内容 preg_match('#"Description"\scontent="(.+?)"\s\/\>#is', $get_contents2, $matchresult); if (isset($matchresult[1]) && $matchresult[1] != ""){ return $matchresult[1]; }else{ return "抱歉,没有找到与“".$name."”相关的百科结果。"; } } function httpGetRequest_baike($url) { $headers = array( "User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:14.0) Gecko/20100101 Firefox/14.0.1", "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", "Accept-Language: en-us,en;q=0.5", "Referer: http://www.baidu.com/" ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $output = curl_exec($ch); curl_close($ch); if ($output === FALSE){ return "cURL Error: ". curl_error($ch); } return $output; } ?>
微信中调用 <?php define("TOKEN", "weixin"); $wechatObj = new wechatCallbackapiTest(); $wechatObj->responseMsg(); class wechatCallbackapiTest { public function valid() { $echoStr = $_GET["echostr"]; //valid signature , option if($this->checkSignature()){ echo $echoStr; exit; } } private function checkSignature() { $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } public function responseMsg() { //get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; logger("R ".$postStr); //extract post data if (!empty($postStr)){ $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $RX_TYPE = trim($postObj->MsgType); switch ($RX_TYPE) { case "text": $resultStr = $this->receiveText($postObj); break; case "event": $resultStr = $this->receiveEvent($postObj); break; default: $resultStr = "unknow msg type: ".$RX_TYPE; break; } logger("T ".$resultStr); echo $resultStr; }else { echo ""; exit; } } private function receiveText($object) { $funcFlag = 0; $keyword = trim($object->Content); $resultStr = ""; $contentStr = ""; include('baike.php'); $contentStr = getEncyclopediaInfo($keyword); $resultStr = $this->transmitText($object, $contentStr, $funcFlag); return $resultStr; } private function receiveEvent($object) { $contentStr = ""; switch ($object->Event) { case "subscribe": $contentStr = "欢迎关注"; } $resultStr = $this->transmitText($object, $contentStr); return $resultStr; } private function transmitText($object, $content, $flag = 0) { $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[text]]></MsgType> <Content><![CDATA[%s]]></Content> <FuncFlag>%d</FuncFlag> </xml>"; $resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content, $flag); return $resultStr; } } function logger($log_content) { } ?> |
