微信公眾號php沒有返回資訊怎麼辦？

微信公眾號php返回資訊的實現方法：

php微信公眾號關注後 回覆一條文字資訊和一條圖文資訊

首先還是啟用伺服器模式 index.php

驗證token 使用 啟用伺服器模式後 把這個index.php 改個名字

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 $echoStr;
exit;
}
}
public function responseMsg()
{
//get post data, May be due to the different environments
//php7 棄用了這個函數 使用file_get_contents('php://input')
//$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：新建一個index.php

接收微信返回的封包 進行處理

<?php
//給微信平臺回覆以防重複推播和報警
ob_clean();//可能在回覆echo之前有輸出內容，所以先用ob_clean()清空輸出快取區
echo "success";
session_start();//用於資料
error_reporting(0);//關閉php提示報錯
date_default_timezone_set('PRC');//統一設定時區
//引數提取和資料查詢及儲存
//獲得引數
$openid = $_GET['openid'];
//接收微信平臺推播過來的封包
//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;
}
//開啟紀錄檔檔案並寫入
