消息自动回复
添加第10行代码，作用是调用第22行的responseMsg回复信息方法<?php
/**
* wechat php test
*/
//define your token
define("TOKEN", "test");
$wechatObj = new wechatCallbackapiTest();
//$wechatObj->valid();
//调用回复方法
$wechatObj -> responseMsg();
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)){
$postObj = simplexml_load_string($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 = "Hello,欢迎关注";
$resultStr = sprintf($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);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>
第46行代码是自动回复的内容$contentStr = "Hello,欢迎关注";
关键词自动回复
用if语句进行判断，if语句格式为：if($keyword=="手机"){}
if (!empty($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(!empty( $keyword ))
{
$msgType = "text";
$contentStr = "Hello";
if($keyword == "手机") //关键词是手机时回复内容
{
$contentStr = "你回复的关键词是手机";
}
if($keyword == "电脑") //关键词是手机时回复内容
{
$contentStr = "你回复的关键词是电脑";
}
if($keyword == "相机") //关键词是手机时回复内容
{
$contentStr = "你回复的关键词是相机";
}
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
echo $resultStr;
}else{
echo "Input something...";
}
}else {
echo "";
exit;
}
关键词为“手机”时回复内容
$contentStr="你回复的关键词是手机";
