Question

访问此API时遇到问题。你能帮我解决我的错吗？

public function index()
{

    require_once('./application/libraries/imagine_autoloader.php');

    $imagine = new \Imagine\Gd\Imagine();

    $image = $imagine->open('assets/a1.jpg'); /**Getting error here */


    $thumbnail = $image->thumbnail(new Imagine\Image\Box(100, 100));
    $thumbnail->save('assets/thumnail_image1.jpg');
    $this->load->view('welcome_message');
}

错误是：

Answer 1

这可能是您所包含的lib的路径问题，另外，您还需要提供所得到的确切错误，如果您使用的是ubuntu服务器，则可以通过命令检查错误日志。...

tail -f /var/log/apache2/error.log

这将向您显示代码中的确切错误。

Answer 2

在您提供的错误中，有一个Gd not installed。

所以您需要设置并启用它。

类似：在Ubuntu / debian上

# apt-get install php7.0-gd
# phpenmod gd

在Centos / Fedora上

# dnf install php-gd
# phpenmod gd
