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：
