使用Slim和Twig提供动态资产

我试图在不使用扩展程序的情况下链接图像,因为它使我更容易维护所有客户端文件。

当浏览器呈现页面时,

assets/images/client应解析为assets/images/client.png

在Slim中,它认为这些是路线而不是处理图像。有什么方法可以通过Slim处理/assets来处理任何事情,让它只是通过常规的http请求吗?

考虑使用Slim返回这些图像,它会保留您手中的控制权:您可以随时更改路径或包含文件夹。您还可以设置其他标头,例如用于缓存。

$app->get('/assets/images/{pathToClientImage}', function($request, $response, $args) {
    $pathToFile = $args['pathToClientImage'];
    $containingFolder = '../clients_images/'; // the actual folder where files are stored
    // since you want to omit file extension in the url, we'll have to find the file
    $matches = glob($containingFolder.$fileName.'.*');
    if ($matches) {
        $clientImagePath = array_shift($matches); // let's grab the first file matching our mask
        $clientImage = @file_get_contents($clientImagePath);
        $finfo = new \Finfo(FILEINFO_MIME_TYPE);
        $response->write($clientImage);
        return $response->withHeader('Content-Type', $finfo->buffer($clientImage));
    } else {
        // if no matches found, throw exception that will be handled by Slim
        throw new \Slim\Exception\NotFoundException($request, $response);
    }
});

如果您可以接受assets/images/client.png(具有文件扩展名)等网址,则可以通过更简单的方式执行此操作:

$app->get('/assets/images/{pathToClientImage}', function($request, $response, $args) {
    $pathToFile = $args['pathToClientImage'];
    $path = '../clients_images/'.$fileName;
    $image = @file_get_contents($path);
    $finfo = new \Finfo(FILEINFO_MIME_TYPE);
    $response->write($image);
    return $response->withHeader('Content-Type', $finfo->buffer($image));
});
