HomeBackend DevelopmentPHP Tutorial有没开发过微信公众号的?

请教一个问题:假设我现在已经申请号了认证订阅号,然后我也启用了服务器配置并且url验证通过了。但是我尝试用自己的微信关注这个订阅号,并且发送消息。理论上微信服务器应该会向url发送用户的信息,包括openid什么的。但是实际上我的url里面并没有接收到任何信息。不知道是否有开发过的大侠指点一下?

我的url内的代码:

traceHttp();define("TOKEN", "4321");$access_token = '1234';$wechatObj = new wechatCallbackapiTest();if (isset($_GET['echostr'])) {    $wechatObj->valid();}else{    $wechatObj->responseMsg();}class wechatCallbackapiTest{    public function valid()    {        $echoStr = $_GET["echostr"];        if($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;        }    }    public function responseMsg()    {        $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];        ob_start();        var_dump($_REQUEST);        $a = ob_get_clean();        file_put_contents('1.xml', $a, FILE_APPEND);        if (!empty($postStr)){            $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);            $fromUsername = $postObj->FromUserName;            $toUsername = $postObj->ToUserName;            $keyword = trim($postObj->Content);            $time = time();            $textTpl = "<xml>                        <ToUserName><![CDATA[%s]]></ToUserName>                        <FromUserName><![CDATA[%s]]></FromUserName>                        <CreateTime>%s</CreateTime>                        <MsgType><![CDATA[%s]]></MsgType>                        <Content><![CDATA[%s]]></Content>                        <FuncFlag>0</FuncFlag>                        </xml>";            if($keyword == "?" || $keyword == "?")            {                $msgType = "text";                $contentStr = date("Y-m-d H:i:s",time());                $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);//                echo $resultStr;                file_put_contents('1.xml', $resultStr, FILE_APPEND);            }        }else{            echo "";            exit;        }    }}function traceHttp(){    logger("\n\nREMOTE_ADDR:".$_SERVER["REMOTE_ADDR"].(strstr($_SERVER["REMOTE_ADDR"],'101.226')? " FROM WeiXin": "Unknown IP"));    logger("QUERY_STRING:".$_SERVER["QUERY_STRING"]);}function logger($log_content){    if(isset($_SERVER['HTTP_APPNAME'])){   //SAE        sae_set_display_errors(false);        sae_debug($log_content);        sae_set_display_errors(true);    }else{ //LOCAL        $max_size = 500000;        $log_filename = "log.xml";        if(file_exists($log_filename) and (abs(filesize($log_filename)) > $max_size)){unlink($log_filename);}        file_put_contents($log_filename, date('Y-m-d H:i:s').' '.$log_content."\r\n", FILE_APPEND);    }}

每次我向订阅号发消息后,1.xml确实会有新内容被记录,但只有这些:
array(3) {  ["signature"]=>  string(40) "2c1f15c808659e38ca8a2bef53068939c7710d09"  ["timestamp"]=>  string(10) "1423321593"  ["nonce"]=>  string(10) "1992378621"}


百思不得其解。

这篇文章我已经看过了,按照文章所说,当我向订阅号发送消息的时候,微信服务器会向订阅号填写的服务器url发送xml格式数据,里面就有用户的openid。问题就是我服务器url这边是接收到微信服务器的发送数据,可是数据里面没有xml格式的数据啊,也没有openid。

腾    讯 微信开发 有技术咨询吧?         程序规则他们定制的  最好问下他们

检查下你服务器配置的消息加解密方式,看是否是明文的

你的代码是什么样程序就会表现什么样
注释掉下面几句:
ob_start();
var_dump($_REQUEST);
 $a = ob_get_clean();
 file_put_contents('1.xml', $a, FILE_APPEND);

然后向你的公众号发送问号(?)试试

问题已经解决了,就是5楼说的问题。不能用
ob_start();
var_dump($_REQUEST);
 $a = ob_get_clean();
