核心代码：
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->ToUserName; $MsgType=$postObj->MsgType; $keyword = trim($postObj->Content); $time = time(); $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[text]]></MsgType> <Content>%s</Content> <FuncFlag>0</FuncFlag> </xml>"; //用 户 名 : $user //密 码 : $pwd //主库域名 : $host //从库域名 : SAE_MYSQL_HOST_S //端 口 : $port //数据库名 : $dbname $dbname = "app_dq095"; $host = "w.rdc.sae.sina.com.cn"; $port = "3306"; $user = "4k514n103z"; $pwd = "2402314li2j1i5im1xy2xizj5y332w2x41k2z203"; /*接着调用mysql_connect()连接服务器*/ // 连主库 $db = mysql_connect($host,$user,$pwd); if(!$db){ die("Connect Server Failed: " . mysql_error($db)); } /*连接成功后立即调用mysql_select_db()选中需要连接的数据库*/ if (!mysql_select_db($dbname)) { die("Select Database Failed: " . mysql_error($db)); } mysql_query("set names utf-8",$db); /*至此连接已完全建立，就可对当前数据库进行相应的操作了*/ /*！！！注意，无法再通过本次连接调用mysql_select_db来切换到其它数据库了！！！*/ /* 需要再连接其它数据库，请再使用mysql_connect+mysql_select_db启动另一个连接*/ /** * 接下来就可以使用其它标准php mysql函数操作进行数据库操作 */ if($keyword=="天气") { $content="请输入地区"; $sql="INSERT INTO `weather`(`id`,`user`,`keyword`) VALUES (NULL,'{$fromUsername}','{$keyword}')"; mysql_query($sql); } else { $sql="SELECT `keyword` FROM `weather` WHERE `user`= '" . $fromUsername .

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; $MsgType=$postObj->MsgType; $keyword = trim($postObj->Content); $time = time(); $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[text]]></MsgType> <Content>%s</Content> <FuncFlag>0</FuncFlag> </xml>"; //用 户 名 : $user //密 码 : $pwd //主库域名 : $host //从库域名 : SAE_MYSQL_HOST_S //端 口 : $port //数据库名 : $dbname $dbname = "app_dq095"; $host = "w.rdc.sae.sina.com.cn"; $port = "3306"; $user = "4k514n103z"; $pwd = "2402314li2j1i5im1xy2xizj5y332w2x41k2z203"; /*接着调用mysql_connect()连接服务器*/ // 连主库 $db = mysql_connect($host,$user,$pwd); if(!$db){ die("Connect Server Failed: " . mysql_error($db)); } /*连接成功后立即调用mysql_select_db()选中需要连接的数据库*/ if (!mysql_select_db($dbname)) { die("Select Database Failed: " . mysql_error($db)); } mysql_query("set names utf-8",$db); /*至此连接已完全建立，就可对当前数据库进行相应的操作了*/ /*！！！注意，无法再通过本次连接调用mysql_select_db来切换到其它数据库了！！！*/ /* 需要再连接其它数据库，请再使用mysql_connect+mysql_select_db启动另一个连接*/ /** * 接下来就可以使用其它标准php mysql函数操作进行数据库操作 */ if($keyword=="天气") { $content="请输入地区"; $sql="INSERT INTO `weather`(`id`,`user`,`keyword`) VALUES (NULL,'{$fromUsername}','{$keyword}')"; mysql_query($sql); } else { $sql="SELECT `keyword` FROM `weather` WHERE `user`= '" . $fromUsername .
