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。

What should I do if the WeChat public account PHP does not return information?

本教程操作环境：Windows7系统、PHP8.1版、Dell G3电脑。

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 $echoStr;
exit;
}
}
public function responseMsg()
{
//get post data, May be due to the different environments
//php7 弃用了这个函数 使用file_get_contents(&#39;php://input&#39;)
//$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
$postStr = file_get_contents(&#39;php://input&#39;);
//extract post data
if (!emptyempty($postStr)){
$postObj = simplexml_load_string($postStr, &#39;SimpleXMLElement&#39;, 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(&#39;PRC&#39;);//统一设置时区
//参数提取和数据查询及保存
//获得参数
$openid = $_GET[&#39;openid&#39;];
//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, &#39;SimpleXMLElement&#39;, 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 "
