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：http://xiazai.jb51.net/201608/yuanma/phpwx(jb51.net).rar

下载地址2：https://mp.weixin.qq.com/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

/**

* wechat php test

*/

//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

$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 = "

%s

0

";

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();”。

/**

* wechat php test

*/

//define your token

define("TOKEN", "weixin");

$wechatObj = new wechatCallbackapiTest();

//$wechatObj->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 = "

%s

0

";

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.weixin.qq.com/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。

/**

* wechat php test

*/

//define your token

define("TOKEN", "weixin");

$wechatObj = new wechatCallbackapiTest();

//$wechatObj->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 = "

%s

0

";

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;

}

}

}

?>
