1、把phpqrcode包放到thinkcmf根目录的simplewind/extend里。

2、

$file_name = "{$this->id}.png";// 计算记录对应的子文件路径（防止每个文件夹内保存的图片数量超过系统限制）$sub_dir = num_divide_dir_path($this->id); $local_dir = "/upload/qrcode/{$sub_dir}"; $local_path = $local_dir."/".$file_name; $full_dir = ROOT_PATH."public".$local_dir; $full_path = $full_dir."/".$file_name;if(!file_exists($full_path)){  if(!is_dir($full_dir)){    mkdir($full_dir, 0777, true);  }  // 这是生成图片的主要方法  import('phpqrcode.phpqrcode',EXTEND_PATH);  \QRcode::png("http://www.baidu.com", $full_path); }//把图片路径传到view页面

$this->assign("qrcode_img", $local_path);

实现代码如下（测试通过）：
