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,",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 class="brush:php;toolbar:false">"; //print_r($json); //echo ""; $result=json_decode($json,true); $ACCESS_TOKEN=$result['access_token']; // $ACCESS_TOKEN; //关注回复 if( $event=="subscribe" ) { $textTpl = "
多图文和一条文本信息
多图文和一条文本信息
因为客服回复消息 只能是一条图文 不然会报错
