微信带参数的二维码生成以及扫码事件逻辑处理

微信生成带参数的二维码有两种：

一、临时二维码：

http请求方式: POST URL: https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=TOKEN POST数据格式：json POST数据例子：{"expire_seconds": 604800, "action_name": "QR_SCENE", "action_info": {"scene": {"scene_id": 123}}} 或者也可以使用以下POST数据创建字符串形式的二维码参数：{"expire_seconds": 604800, "action_name": "QR_STR_SCENE", "action_info": {"scene": {"scene_str": "test"}}}

二、永久二维码：

http请求方式: POST URL: https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=TOKEN POST数据格式：json POST数据例子：{"action_name": "QR_LIMIT_SCENE", "action_info": {"scene": {"scene_id": 123}}} 或者也可以使用以下POST数据创建字符串形式的二维码参数： {"action_name": "QR_LIMIT_STR_SCENE", "action_info": {"scene": {"scene_str": "test"}}}

生成带参数的二维码逻辑处理：

public function erweima(){
$id = (int)$this->input->get('id');
$data = $this->db->where('id',$id)->get($this->table)->row_array();
$dir = CACHEPATH."ercode/zhuanjia/";
sys_mkdirs($dir);
if(!file_exists($dir."/qrcode_".$id.".jpg")){
$jsonarr= $this->dweixin->get_wxma('ZHUANJIA_'.$id,1);
$path_1 = 'https://mp.weixin.qq.com/cgi-bin/showqrcode?ticket='.$jsonarr['ticket'].'';
// 图片二
$image_1 = imagecreatefromstring(file_get_contents($path_1));
imagejpeg($image_1, $dir."qrcode_".$id.".jpg");
}
$img = SITE_URL.'cache/ercode/zhuanjia/qrcode_'.$id.'.jpg?id='.SYS_TIME.'';
$this->template->assign(array(
'imagesrc' => $img,
));
$this->template->display(APP_C.'_erweima.html');
}

 

public function get_wxma($kid,$type=0){

$acctoken = $this->red_acctoke();//获取token
$poststr='{"action_name": "QR_LIMIT_SCENE", "action_info": {"scene": {"scene_id":'.$kid.'}}}';
if($type){
$poststr='{"action_name": "QR_LIMIT_STR_SCENE", "action_info": {"scene": {"scene_str":"'.$kid.'"}}}';
}
$json = $this->post_url("https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=". $acctoken ."",$poststr);
$json_data = json_decode($json,true);

if($json_data["errcode"]){
$this->log_txt(FCPATH."/dweixin-err.txt",'生成二维码失败token---'.$acctoken.' --------type:'.$type.'--kid:'.$kid.' '.$poststr.'- '.$json);
return false;
}
return $json_data;
}

扫描二维码的逻辑处理：

2 扫描带参数二维码事件（微信公众号消息推送中的事件）

public function responseMsg(){
$postStr = file_get_contents("php://input");
if(!empty($postStr)){
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$this->Uopenid = $postObj->FromUserName;
$this->Username = $postObj->ToUserName;
$this->keyword = trim($postObj->Content);
$msgType = $postObj->MsgType;
// $this->dweixin->log_txt("weixin_saoma.txt",$postObj->EventKey.'test--1111-无法错误'.$msgType);
switch($msgType){
case "event":
$event = $postObj->Event;
switch($event){
case "subscribe": //关注
$resultStr=$this->E_guanzhu($postObj->EventKey);
break;

break;

break;

}
if(!$resultStr){
