首先開啟微信公眾平臺,登入自己的賬號,
然後將自己的外網的url路徑寫入,寫入token值,加入方式選為明文方式,並用fz上傳你要寫入的token值判斷是否正確。
<?php /** * wechat php test */ //define your token define("TOKEN", "weixin"); $wechatObj = new wechatCallbackapiTest(); $wechatObj->valid(); 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)){ /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection, the best way is to check the validity of xml by yourself */ libxml_disable_entity_loader(true); $postObj = simplexml_load_string($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[%s]]></MsgType> <Content><![CDATA[%s]]></Content> <FuncFlag>0</FuncFlag> </xml>"; if(!empty( $keyword )) { $msgType = "text"; $contentStr = "Welcome to wechat world!"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; }else{ echo "Input something..."; } }else { echo ""; exit; } } private function checkSignature() { // you must define TOKEN by yourself if (!defined("TOKEN")) { throw new Exception('TOKEN is not defined!'); } $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); // use SORT_STRING rule sort($tmpArr, SORT_STRING); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } } ?>
當稽核通過通過token值的時候在原始碼上新增天氣查詢的功能
<?php /** * wechat php test */ //define your token define("TOKEN", "weixin"); $wechatObj = new wechatCallbackapiTest(); $wechatObj->responseMsg(); //$wechatObj->valid(); 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); $RX_TYPE = trim($postObj->MsgType); switch($RX_TYPE) { case "text": $resultStr = $this->handleText($postObj); break; case "event": $resultStr = $this->handleEvent($postObj); break; default: $resultStr = "Unknow msg type: ".$RX_TYPE; break; } echo $resultStr; }else { echo ""; exit; } } public function handleText($postObj) { $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[%s]]></MsgType> <Content><![CDATA[%s]]></Content> <FuncFlag>0</FuncFlag> </xml>"; if(!empty( $keyword )) { $msgType = "text"; $url="http://api.k780.com:88/?app=weather.future&appkey=14323&sign=0111aa8a973785f0f0926aff75f5af52&format=json&weaid=".$keyword; $str=file_get_contents($url); $s=json_decode($str); $a=$s->result; $date=date("Y-m-d"); foreach($a as $k => $v){ if($v->days == $date){ $today=$a[$k]; } } $msgType = "text"; if($today->citynm==""){ $contentStr='請正確輸入城市名'; }else{ $contentStr = '城市:'.$today->citynm.',時間:'.$today->days.',星期:'.$today->week.',溫度:'.$today->temperature.',風向:'.$today->wind.',風級:'.$today->winp; } $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; }else{ echo "Input something..."; } } public function handleEvent($object) { $contentStr = ""; switch ($object->Event) { case "subscribe": $contentStr = "感謝您關注【卓錦蘇州】"."\n"."微訊號:zhuojinsz"."\n"."卓越錦繡,名城蘇州,我們為您提供蘇州本地生活指南,蘇州相關資訊查詢,做最好的蘇州微信平臺。"."\n"."目前平臺功能如下:"."\n"."【1】 查天氣,如輸入:蘇州天氣"."\n"."【2】 查公交,如輸入:蘇州公交178"."\n"."【3】 翻譯,如輸入:翻譯I love you"."\n"."【4】 蘇州資訊查詢,如輸入:蘇州觀前街"."\n"."更多內容,敬請期待..."; break; default : $contentStr = "Unknow Event: ".$object->Event; break; } $resultStr = $this->responseText($object, $contentStr); return $resultStr; } public function responseText($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; } 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; } } } ?>
完成!!!!
