搜索书名返回是xml格式数据：
核心代码如下：
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->ToUserName; $keyword = trim($postObj->Content); $time = time(); $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[news]]></MsgType> <ArticleCount>3</ArticleCount> <Articles> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[s]]></Description> <PicUrl><![CDATA[url]]></PicUrl> <Url><![CDATA[url]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[s]]></Description> <PicUrl><![CDATA[url]]></PicUrl> <Url><![CDATA[url]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[s]]></Description> <PicUrl><![CDATA[url]]></PicUrl> <Url><![CDATA[url]]></Url> </item> </Articles> <FuncFlag>1</FuncFlag> </xml>"; $url="http://222.206.65.12/opac/search_rss.php?dept=ALL&title={$keyword}&doctype=ALL&lang_code=ALL&match_flag=forward&displaypg=20&showmode=list&orderby=DESC&sort=CATA_DATE&onlylendable=no"; $fa=file_get_contents($url); $f=simplexml_load_string($fa); $da1=$f->channel->item[0]->title; $da2=$f->channel->item[1]->title; $da3=$f->channel->item[2]->title; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time,$da1,$da2,$da3); echo $resultStr;
index.php整体代码如下：
<?php /** * wechat php test */ //define your token 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; } } public function responseMsg() { //get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //extract post data if (!empty($postStr)){ $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->ToUserName; $keyword = trim($postObj->Content); $time = time(); $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[news]]></MsgType> <ArticleCount>3</ArticleCount> <Articles> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[s]]></Description> <PicUrl><![CDATA[url]]></PicUrl> <Url><![CDATA[url]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[s]]></Description> <PicUrl><![CDATA[url]]></PicUrl> <Url><![CDATA[url]]></Url> </item> <item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[s]]></Description> <PicUrl><![CDATA[url]]></PicUrl> <Url><![CDATA[url]]></Url> </item> </Articles> <FuncFlag>1</FuncFlag> </xml>"; $url="http://222.206.65.12/opac/search_rss.php?dept=ALL&title={$keyword}&doctype=ALL&lang_code=ALL&match_flag=forward&displaypg=20&showmode=list&orderby=DESC&sort=CATA_DATE&onlylendable=no"; $fa=file_get_contents($url); $f=simplexml_load_string($fa); $da1=$f->channel->item[0]->title; $da2=$f->channel->item[1]->title; $da3=$f->channel->item[2]->title; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time,$da1,$da2,$da3); echo $resultStr; }else { echo ""; 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; } } } ?>
