微信开发前，需要设置token，这个是微信设置的，可以任意设置，用来实现微信通讯。这里有一个别人写的微信类，功能还比较不错。weixin.class.php代码如下
token = $token;
$this->debug = $debug;
}
//获得用户发过来的消息（消息内容和消息类型 ）
public function getMsg()
{
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
if (!empty($postStr)) {
$this->msg = (array)simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$this->msgtype = strtolower($this->msg['MsgType']);
}
}
//回复文本消息
public function makeText($text='')
{
$CreateTime = time();
$FuncFlag = $this->setFlag ? 1 : 0;
$textTpl = "
msg['FromUserName']}]]>
msg['ToUserName']}]]>
{$CreateTime}
%s
";
return sprintf($textTpl,$text,$FuncFlag);
}
//根据数组参数回复图文消息
public function makeNews($newsData=array())
{
$CreateTime = time();
$FuncFlag = $this->setFlag ? 1 : 0;
$newTplHeader = "
msg['FromUserName']}]]>
msg['ToUserName']}]]>
{$CreateTime}
%s";
$newTplItem = "
";
$newTplFoot = "
%s
";
$Content = '';
$itemsCount = count($newsData['items']);
$itemsCount = $itemsCount$item) {
if ($keycheckSignature()) {
if( $_SERVER['REQUEST_METHOD']=='GET' )
{
echo $_GET['echostr'];
exit;
}
}else{
exit;
}
}
private function checkSignature()
{
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$tmpArr = array($this->token, $timestamp, $nonce);
sort($tmpArr);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>
