【微信开发|PHP】设置关注自动回复 关键词自动回复。

一、设置公众平台服务器配置

二、do it

<?php

session_start();

ini_set("session.bug_compat_42","Off");

traceHttp();

define("TOKEN", "weixin");

$wechatObj = new wechatCallbackapiTest();

if (isset($_GET['echostr'])) {

$wechatObj->valid();

}else{

$wechatObj->responseMsg();

}

class wechatCallbackapiTest

{

public function valid()

{

$echoStr = $_GET["echostr"];

if($this->checkSignature()){

echo $echoStr;

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;

}

}

# 关键词自动回复

public function responseMsg()

{

$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];

if (!empty($postStr)){

$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);

$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>";

$msgType = "text";

//判断是否为关注

if($postObj->Event=="subscribe")

{

$contentStr="欢迎关注奥！";

$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);

echo $resultStr;

}

//判断是否为用户发送消息

if(!empty( $keyword )){

switch($keyword){

case 1:

$contentStr="1111111";

break;

case 2:

break;

}

$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);

echo $resultStr;

}else{

echo "";

}

}else {

echo "";

exit;

}

}

}

function traceHttp()

{

logger("\n\nREMOTE_ADDR:".$_SERVER["REMOTE_ADDR"].(strstr($_SERVER["REMOTE_ADDR"],'101.226')? " FROM WeiXin": "Unknown IP"));

logger("QUERY_STRING:".$_SERVER["QUERY_STRING"]);

}

function logger($log_content)

{

if(isset($_SERVER['HTTP_APPNAME'])){ //SAE

sae_set_display_errors(false);

sae_debug($log_content);

sae_set_display_errors(true);

}else{ //LOCAL

$max_size = 500000;

$log_filename = "log.xml";

if(file_exists($log_filename) and (abs(filesize($log_filename)) > $max_size)){unlink($log_filename);}

file_put_contents($log_filename, date('Y-m-d H:i:s').$log_content."\r\n", FILE_APPEND);

}

}

?>

直接拿走上传服务器就可以用了，自动回复词库我会慢慢更新
