《PHP实战：PHP微信公众号开发（3）PHP实现简单微信文本通讯》要点：
本文介绍了PHP实战：PHP微信公众号开发（3）PHP实现简单微信文本通讯，希望对您有用。如果有疑问，可以联系我们。
微信开发前,需要设置token,这个是微信设置的,可以任意设置,用来实现微信通讯.这里有一个别人写的微信类,功能还比较不错.weixin.class.PHP代码如下PHP编程
<?PHP class Weixin { public $token = '';//token public $debug = false;//是否debug的状态标示,方便我们在调试的时候记录一些中间数据 public $setFlag = false; public $msgtype = 'text'; //('text','image','location') public $msg = array(); public function __construct($token,$debug) { $this->token = $token; $this->debug = $debug; } //获得用户发过来的消息(消息内容和消息类型 ) 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']); } } //回复文本消息 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,$FuncFlag); } //根据数组参数回复图文消息 public function makeNews($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> <MsgType><![CDATA[news]]></MsgType> <Content><![CDATA[%s]]></Content> <ArticleCount>%s</ArticleCount><Articles>"; $newTplItem = "<item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item>"; $newTplFoot = "</Articles> <FuncFlag>%s</FuncFlag> </xml>"; $Content = ''; $itemsCount = count($newsData['items']); $itemsCount = $itemsCount < 10 ? $itemsCount : 10;//微信公众平台图文回复的消息一次最多10条 if ($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; } } } ?>
接着正式开发,使用百度SVN地址,创建weixinapi.PHP文件,这个根据你后台设置名称.PHP编程
<?PHP define("TOKEN",""); define('DEBUG',false); include_once('weixin.class.PHP'); require_once("db.PHP"); $weixin = new Weixin(TOKEN,DEBUG);//实例化 $weixin->getMsg(); $type = $weixin->msgtype;//消息类型 $keyword = $weixin->msg['Content'];//获取的文本 if ($type==='text') { $reply = $weixin->makeText($key); }elseif($type==='event'){//第一次关注推送事件 $reply = $weixin->makeText("欢迎关注"); }else{//其他类型 $reply = $weixin->makeText("暂时没有图片,声音,地理位置等功能,后续开发会增加,感谢你关注"); } $weixin->reply($reply);
