关注微信或者向微信公众号发送信息, 都可以自动回复内容,开发模式下怎么写php代码呢?
这里以CI框架控制器里示例下, 当然如果你是其它框架, 或者是原生PHP, 那么直接里面的代码拷贝出来, 做相应的替换就可以了
class Wx extends CI_Controller {
private $wx_token = "zhuangzi";
private $AppID = "wx6833ed680a3432af";
private $AppSecret = "3faeb8577cc8f2728732a1e5e0291107";
public function index()
{
if(!isset($_GET["echostr"]))
{ //验证过了， 就没有echostr参数了
$this->responseMsg(); //关注公众号/输入hello都将会自动回复
}else{
$this -> _check_signature();//验证消息的确来自微信服务器
//验证代码: http://www.ncyteng.com/news/show/169
}
}
public function responseMsg(){
//get post data, May be due to the different environments
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //接收微信发来的XML数据
//extract post data
if(!empty($postStr)){
//解析post来的XML为一个对象$postObj
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName; //请求消息的用户
$toUsername = $postObj->ToUserName; //"我"的公众号id
$keyword = trim($postObj->Content); //消息内容
$time = time(); //时间戳
$msgtype = 'text'; //消息类型：文本
$event = $postObj->Event;
$textTpl = "<xml>
<ToUserName><![CDATA[%s]]></ToUserName>
<FromUserName><![CDATA[%s]]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><![CDATA[%s]]></MsgType>
<Content><![CDATA[%s]]></Content>
</xml>";
if($event == "subscribe"){
$contentStr = '欢迎光临庄子公众号';
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr);
echo $resultStr;
exit();
}
if($keyword == 'hello'){
//输入 hello 将会回复的内容
$contentStr = 'hello world!!!';
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype,$contentStr);
echo $resultStr;
exit();
}
else{
$contentStr = '现在只回复输入 hello, 其它的俺还暂时还不理人哟';
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgtype, $contentStr);
echo $resultStr;
exit();
}
}
}
