    微信公众号php没有返回信息怎么办?

    微信公众号php返回信息的实现方法:

    php微信公众号关注后 回复一条文本信息和一条图文信息

    首先还是启用服务器模式 index.php

    验证token 使用 启用服务器模式后 把这个index.php 改个名字

    下一步:

    <?php
    /**
    * wechat php test
    * update time: 20141008
    */
    //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 $echoStr;
    exit;
    }
    }
    public function responseMsg()
    {
    //get post data, May be due to the different environments
    //php7 弃用了这个函数 使用file_get_contents('php://input')
    //$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
    $postStr = file_get_contents('php://input');
    //extract post data
    if (!emptyempty($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(!emptyempty( $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()
    {
    $signature = $_GET["signature"];
    $timestamp = $_GET["timestamp"];
    $nonce = $_GET["nonce"];
    $token = TOKEN;
    $tmpArr = array($token, $timestamp, $nonce);
    sort($tmpArr, SORT_STRING);
    $tmpStr = implode( $tmpArr );
    $tmpStr = sha1( $tmpStr );
    if( $tmpStr == $signature ){
    return true;
    }
    else{
    return false;
    }
    }
    }
    ?>

    第二步:新建一个index.php

    接收微信返回的数据包 进行处理

    <?php
    //给微信平台回复以防重复推送和报警
    ob_clean();//可能在回复echo之前有输出内容,所以先用ob_clean()清空输出缓存区
    echo "success";
    session_start();//用于数据
    error_reporting(0);//关闭php提示报错
    date_default_timezone_set('PRC');//统一设置时区
    //参数提取和数据查询及保存
    //获得参数
    $openid = $_GET['openid'];
    //接收微信平台推送过来的数据包
    //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);
    $toUserName = $postObj->ToUserName;
    $fromUserName = $postObj->FromUserName;
    $msgType = $postObj->MsgType;
    $event = $postObj->Event;
    $cardId = $postObj->CardId;
    $userCardCode = $postObj->UserCardCode;
    $eventKey = $postObj->EventKey;
    $Status = $postObj->Status;
    $Content = $postObj->Content;
    }
    //打开日志文件并写入
    $date=date("Y-m-d");//获取当前日期
    $TxtRes = fopen("log/".$date.".txt","a+");
    $datetime=date("Y-m-d H:i:s");//获取当前时间
    fwrite($TxtRes,"微信平台事件推送:");
    fwrite($TxtRes,"datetime=");fwrite($TxtRes,$datetime);
    fwrite($TxtRes,",openid=");fwrite($TxtRes,$postStr);
    fwrite($TxtRes,",openid=");fwrite($TxtRes,$openid);

    fwrite($TxtRes,",eventKey=");fwrite($TxtRes,$eventKey);
    fwrite($TxtRes,",Status=");fwrite($TxtRes,$Status);
    fwrite($TxtRes,",Content=");fwrite($TxtRes,$Content);
    fwrite($TxtRes,"\r\n");
    fclose($TxtRes);//关闭指针
    //获取access_token
    $appid = "";
    $secret = "";
    $TOKEN_URL="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$secret;
    $json=file_get_contents($TOKEN_URL);
    //echo "<pre>";
    //print_r($json);
    //echo "</pre>";
    $result=json_decode($json,true);
    $ACCESS_TOKEN=$result['access_token'];
    // $ACCESS_TOKEN;
    //关注回复
    if( $event=="subscribe" )
    {
        $textTpl = "<xml>
    <ToUserName><![CDATA[%s]]></ToUserName>
    <FromUserName><![CDATA[%s]]></FromUserName>
    <CreateTime>%s</CreateTime>

        $time = time(); //时间戳
        $msgType = 'text'; //消息类型:文本
        //
            $contentStr = "这是文本信息";
        //$contentStr = preg_replace("#\\\u([0-9a-f]+)#ie","iconv('UCS-2','UTF-8', pack('H4', '\\1'))",$contentStr);//对emoji unicode进行二进制pack并转utf8
        $resultStr = sprintf($textTpl, $fromUserName, $toUserName, $time, $msgType, $contentStr);
        echo $resultStr;
    //打开日志文件并写入
