微信公众平台,php开发的简单问题
我注册了一个微信公众平台的测试账号,并且把url和token都做了设置
url:***.***.com/weixin/weinxin.php
token:weixin
这个url是真实存在且外网可以访问的,weixin.php我用的是腾讯官方提供的
<?php/** * wechat php test *///define your tokendefine("TOKEN", "weixin");$wechatObj = new wechatCallbackapiTest();$wechatObj->valid();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 == $signature ){ return true; }else{ return false; } }}?>
我用自己的微信号关注这个测试微信号,完后我用自己的微信号发消息给这个测试账号,但是并没有收到测试账号回复我的消息,照理说不是应该回复给我相同的消息的吗?有谁弄过这个,什么原因啊
回复讨论(解决方案)
这个是验证token的,如果要回复的话,$wechatObj->valid();要注释掉,换成$wechatObj->responseMsg()
这个函数是微信官方demo里的
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 = "
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;
}
}
upup! 不错
