<span style=\"white-space: pre;\"> </span>$data=\'\'; 
<span style=\"white-space: pre;\"> </span>file_put_contents(\"1.txt\",var_export($_FILES,true).\"\\r\\n\",FILE_APPEND); 
<span style=\"white-space: pre;\"> </span>if(!empty($_FILES[\'upload\'][\'tmp_name\'])){ 
<span style=\"white-space: pre;\">  </span>if(empty($_FILES[\'upload\'][\'type\'])){ 
<span style=\"white-space: pre;\">   </span>IO::Debug(\'文件类型不合法\'); 
<span style=\"white-space: pre;\">  </span>} 
<span style=\"white-space: pre;\">  </span>if(!in_array($_FILES[\'upload\'][\'type\'],array( 
<span style=\"white-space: pre;\">   </span>\'image/gif\', 
<span style=\"white-space: pre;\">   </span>\'image/pjpeg\', 
<span style=\"white-space: pre;\">   </span>\'image/jpeg\', 
<span style=\"white-space: pre;\">   </span>\'image/x-png\', 
<span style=\"white-space: pre;\">   </span>\'image/png\', 
<span style=\"white-space: pre;\">   </span>\'image/bmp\' 
<span style=\"white-space: pre;\">  </span>))){ 
<span style=\"white-space: pre;\">   </span>IO::Debug($_FILES[\'upload\'][\'type\'].\'文件类型不合法\'); 
<span style=\"white-space: pre;\">  </span>} 
<span style=\"white-space: pre;\">  </span>$data=file_get_contents($_FILES[\'upload\'][\'tmp_name\']); 
<span style=\"white-space: pre;\">  </span>file_put_contents(\"1.txt\",var_export($data,true).\"\\r\\n\",FILE_APPEND);

<span style=\"white-space: pre;\"> </span>var $data = JSON.parse(res.data); 
  if (typeof ($data.data) != \"undefined\" && $data.code){ 
  var imgBase64 = \"data:image/jpeg;base64,\" + $data.data; 
  }
