本篇內容主要講解“微信公眾號php沒有返回信息如何解決”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“微信公眾號php沒有返回信息如何解決”吧!
微信公眾號php沒有返回信息的解決辦法：1、啟用服務器模式；2、通過“define("TOKEN", "weixin");”驗證token；3、新建一個index.php，接收微信返回的數據包并進行處理即可。
微信公眾號php返回信息的實現方法：
php微信公眾號關注后 回復一條文本信息和一條圖文信息
首先還是啟用服務器模式 index.php
驗證token 使用 啟用服務器模式后 把這個index.php 改個名字
下一步：
第二步：新建一個index.php<?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;
}
}
}
?>
接收微信返回的數據包 進行處理
<?php
//給微信平臺回復以防重復推送和報警
ob_clean();//可能在回復echo之前有輸出內容，所以先用ob_clean()清空輸出緩存區
echo "success";
session_start();//用于數據
error_reporting(0);//關閉php提示報錯
date_default_timezone_set('PRC');//統一設置時區
//參數提取和數據查詢及保存
//獲得參數
$openid = $_GET['openid'];
//接收微信平臺推送過來的數據包
//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);
