Before WeChat development, you need to set the token. This is set by WeChat and can be set arbitrarily to implement WeChat communication. Here is a WeChat class written by someone else, which has pretty good functions. The weixin.class.php code is as follows
<?php
class Weixin
{
public $token = '';//token
public $debug = false;//是否debug的狀態(tài)標(biāo)示，方便我們?cè)谡{(diào)試的時(shí)候記錄一些中間數(shù)據(jù)
public $setFlag = false;
public $msgtype = 'text'; //('text','image','location')
public $msg = array();
public function __construct($token,$debug)
{
$this->token = $token;
$this->debug = $debug;
}
//獲得用戶發(fā)過來的消息（消息內(nèi)容和消息類型 ）
public function getMsg()
{
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
if (!empty($postStr)) {
$this->msg = (array)simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$this->msgtype = strtolower($this->msg['MsgType']);
}
}
//回復(fù)文本消息
public function makeText($text='')
{
$CreateTime = time();
$FuncFlag = $this->setFlag ? 1 : 0;
$textTpl = "<xml>
<ToUserName><![CDATA[{$this->msg['FromUserName']}]]></ToUserName>
<FromUserName><![CDATA[{$this->msg['ToUserName']}]]></FromUserName>
<CreateTime>{$CreateTime}</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[%s]]></Content>
<FuncFlag>%s</FuncFlag>
</xml>";
return sprintf($textTpl,$text,$FuncFlag);
}
//根據(jù)數(shù)組參數(shù)回復(fù)圖文消息
public function makeNews($newsData=array())
{
$CreateTime = time();
$FuncFlag = $this->setFlag ? 1 : 0;
$newTplHeader = "<xml>
<ToUserName><![CDATA[{$this->msg['FromUserName']}]]></ToUserName>
<FromUserName><![CDATA[{$this->msg['ToUserName']}]]></FromUserName>
<CreateTime>{$CreateTime}</CreateTime>

$newTplItem = "<item>

$newTplFoot = "</Articles>
<FuncFlag>%s</FuncFlag>
</xml>";
$Content = '';
$itemsCount = count($newsData['items']);
$itemsCount = $itemsCount < 10 ? $itemsCount : 10;//微信公眾平臺(tái)圖文回復(fù)的消息一次最多10條
if ($itemsCount) {
foreach ($newsData['items'] as $key => $item) {
if ($key<=9) {
$Content .= sprintf($newTplItem,$item['title'],$item['description'],$item['picurl'],$item['url']);
}
}
}
$header = sprintf($newTplHeader,$newsData['content'],$itemsCount);
$footer = sprintf($newTplFoot,$FuncFlag);
return $header . $Content . $footer;
}
public function reply($data)
{
echo $data;
}
public function valid()
{
if ($this->checkSignature()) {
if( $_SERVER['REQUEST_METHOD']=='GET' )
{
echo $_GET['echostr'];
exit;
}
}else{
exit;
}
}
private function checkSignature()
{
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$tmpArr = array($this->token, $timestamp, $nonce);
sort($tmpArr);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>Then proceed to formal development. Use the Baidu SVN address to create the weixinapi.php file. This is named according to your background settings.
<?php
define("TOKEN", "");
define('DEBUG', false);
include_once('weixin.class.php');
require_once("db.php");
$weixin = new Weixin(TOKEN,DEBUG);//實(shí)例化
$weixin->getMsg();
$type = $weixin->msgtype;//消息類型
$keyword = $weixin->msg['Content'];//獲取的文本
if ($type==='text') {
$reply = $weixin->makeText($key);
}elseif($type==='event'){//第一次關(guān)注推送事件
$reply = $weixin->makeText("歡迎關(guān)注");
}else{//其他類型
$reply = $weixin->makeText("暫時(shí)沒有圖片,聲音,地理位置等功能,后續(xù)開發(fā)會(huì)增加,感謝你關(guān)注");
}
$weixin->reply($reply);In this way, an example is implemented. For the first time, we focus on event replies, non-text replies, and text replies. The text replies here return whatever you input.
The specific implementation function is written in the text reply.
Other functions will not be implemented for the time being, and the specific development will be discussed in the next section.
