本文实例为大家分享了php微信文本消息自动回复 别代码，供大家参考，具体内容如下
1.PHP示例代码下载 下载地址1：/08/yuanma/phpwx().rar
下载地址2：https://mp./wiki/home/index.html(开始开发-》接入指南-》PHP示例代码下载)
2.wx_sample.php初始代码
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
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!empty($postStr)){
/* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,
the best way is to check the validity of xml by yourself */
libxml_disable_entity_loader(true);
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$textTpl = "%s0";
if(!empty( $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()
{
// you must define TOKEN by yourself
if (!defined("TOKEN")) {
throw new Exception('TOKEN is not defined!');
}
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$token = TOKEN;
$tmpArr = array($token, $timestamp, $nonce);
// use SORT_STRING rule
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>
3.调用回复信息方法 在wx_sample.php文件中注释掉$wechatObj->valid();，在其下增加一句“$wechatObj->responseMsg();”。
valid();//接口验证
$wechatObj->responseMsg();//调用回复消息方法
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
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!empty($postStr)){
/* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,
the best way is to check the validity of xml by yourself */
libxml_disable_entity_loader(true);
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$textTpl = "%s0";
if(!empty( $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()
{
// you must define TOKEN by yourself
if (!defined("TOKEN")) {
throw new Exception('TOKEN is not defined!');
}
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$token = TOKEN;
$tmpArr = array($token, $timestamp, $nonce);
// use SORT_STRING rule
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>
4.关键词自动回复和关注回复 $keyword保存着用户微信端发来的文本信息。
官方开发者文档：https://mp./wiki/home/index.html(消息管理-》接收消息-接收事件推送-》1.关注/取消关注事件)
关注事件与一般的文本消息有两处不同，一是MsgType值是event，二是增加了Event值是subscribe。由于官方文档(最初的wx_sample.php)没有提取这个参数，需要我们自己提取。在程序中增加两个变量$msgType和$event。
valid();//接口验证
$wechatObj->responseMsg();//调用回复消息方法
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
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!empty($postStr)){
/* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,
the best way is to check the validity of xml by yourself */
libxml_disable_entity_loader(true);
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$msgType = $postObj->MsgType;//消息类型
$event = $postObj->Event;//时间类型，subscribe(订阅)、unsubscribe(取消订阅)
$textTpl = "%s0";
switch($msgType){
case "event":
if($event=="subscribe"){
$contentStr = "Hi,欢迎关注海仙日用百货!"."\n"."回复数字'1',了解店铺地址."."\n"."回复数字'2',了解商品种类.";
}
break;
case "text":
switch($keyword){
case "1":
$contentStr = "店铺地址："."\n"."杭州市江干艮山西路233号新东升市场地下室第一排.";
break;
case "2":
$contentStr = "商品种类:"."\n"."杯子、碗、棉签、水桶、垃圾桶、洗碗巾(刷)、拖把、扫把、"
."衣架、粘钩、牙签、垃圾袋、保鲜袋(膜)、剪刀、水果刀、饭盒等.";
break;
default:
$contentStr = "对不起,你的内容我会稍后回复";
}
break;
}
$msgType = "text";
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
echo $resultStr;
}else {
echo "";
exit;
}
}
private function checkSignature()
{
// you must define TOKEN by yourself
if (!defined("TOKEN")) {
throw new Exception('TOKEN is not defined!');
}
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$token = TOKEN;
$tmpArr = array($token, $timestamp, $nonce);
// use SORT_STRING rule
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>
