thinkphp3.2 上传图片兼容小程序

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

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/\',
            )
        ]
    ]
);
