微信公众号php没有返回信息的解决办法：1、启用服务器模式；2、通过“define("TOKEN", "weixin");”验证token；3、新建一个index.php，接收微信返回的数据包并进行处理即可。
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：
新建一个index.php<?php//define your tokendefine("TOKEN", "weixin");$wechatObj = new wechatCallbackapiTest();$wechatObj->valid();class wechatCallbackapiTest{public function valid(){$echoStr = $_GET["echostr"];//valid signature , optionif($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 dataif (!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 == $signature ){return true;}else{return false;}}}?>
接收微信返回的数据包 进行处理
<?php//给微信平台回复以防重复推送和报警ob_clean();//可能在回复echo之前有输出内容，所以先用ob_clean()清空输出缓存区echo "success";session_start();//用于数据error_reporting(0);//关闭php提示报错date_default_timezone_set('PRC');//统一设置时区//参数提取和数据查询及保存//获得参数$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 = $GLOBALS["HTTP_RAW_POST_DATA"];//extract post dataif( !empty($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,",toUserName=");fwrite($TxtRes,$toUserName);fwrite($TxtRes,",fromUserName=");fwrite($TxtRes,$fromUserName);fwrite($TxtRes,",msgType=");fwrite($TxtRes,$msgType);fwrite($TxtRes,",event=");fwrite($TxtRes,$event);fwrite($TxtRes,",cardId=");fwrite($TxtRes,$cardId);fwrite($TxtRes,",userCardCode=");fwrite($TxtRes,$userCardCode);fwrite($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><MsgType><![CDATA[%s]]></MsgType><Content><![CDATA[%s]]></Content><FuncFlag>0</FuncFlag></xml>"; $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 $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,"文本："); fwrite($TxtRes,"datetime=");fwrite($TxtRes,$datetime); fwrite($TxtRes,",resultStr=");fwrite($TxtRes,$resultStr); fwrite($TxtRes,"\r\n"); fclose($TxtRes);//关闭指针 function https_request($url,$data = null){ $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); if (!empty($data)){ curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return $output; }//图文信息//图文信息 id 调用微信接口 查询素材内容 就好 $media_id='EdJONlffwfqP8TJrKDcce-IuZKWaOKjX8tbiQknZeLw'; $url = 'https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token='.$ACCESS_TOKEN; $data = '{ "touser":"'.$fromUserName.'", "msgtype":"mpnews", "mpnews": { "media_id":"'.$media_id.'" } }'; $result = https_request($url,$data); //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,"图文："); fwrite($TxtRes,"datetime=");fwrite($TxtRes,$datetime); fwrite($TxtRes,",data=");fwrite($TxtRes,$data); fwrite($TxtRes,"\r\n"); fwrite($TxtRes,",resultStr=");fwrite($TxtRes,$result); fwrite($TxtRes,"\r\n"); fclose($TxtRes);//关闭指针}?>
