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

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。

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：

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 = "


%s


0
";
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

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 "
";
//print_r($json);
//echo "
";
$result=json_decode($json,true);
$ACCESS_TOKEN=$result['access_token'];
// $ACCESS_TOKEN;
//关注回复
if( $event=="subscribe" )
{
    $textTpl = "


%s


0
";
    $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
}
?>
