第一步在配置文件中设置图片的大小和路径
return array( //\'配置项\'=>\'配置值\' \'img_save\'=>[ \'size\' =>[ \'app_gszc_Card\'=>[ \'compress\'=>array( \'w\'=> 720, \'h\'=> 520 ), \'page_size\'=>array( \'w\'=> 720, \'h\'=> 520 ), ], ], \'save_path\'=>[ \'app_gszc_Card\' => array( \'origin\' => \'./Uploads/gszc_card/origin/\', \'page_size\' => \'./Uploads/gszc_card/page_size/\', ) ] ] );
二.上传图片类文件
