从amazon s3 buckets子文件夹中获取文件

Question

我试图从亚马逊S3桶子文件夹中获取所有文件,并使其可以在网页中下载.

我有一个叫做图像的桶.在那个桶里面我有一些其他的文件夹.现在我试图获取该子文件夹中的所有文件并在页面中显示它.S3铲斗:/ images/images/test1// images/test2// images/test1/1/images/test1/2/images/test1/1/item

我试过这样,但无法得到预期的结果.

// Target files full path : images/test1/1/item 

$bucketName = 'images';
$source = '/test1/1/item' 

$image = $this->s3->getBucket($bucketName);
foreach ($image as $key=>$data){
   $k = $data['name'];
   print_r($k); // now this gives me full list of everything inside the images bucket. 
}

现在,如果我想从存储桶中获取对象,我可以使用getObject,我尝试这样做:

$result = $this->s3->getObject($image); // I am confused about this one

任何建议将不胜感激.谢谢,

在使用Josue Ibarra的以下答案后,我得到了类似的东西

哪个需要是可下载的链接.

请建议我链接或给我一些想法我该怎么做.

Answer 1

我不久前做了这个功能

public function list_s3_bucket($bucket_name)
{
    // initialize the data array
    $data;
    $bucket_content = $this->s3->getBucket($bucket_name);

    foreach ($bucket_content as $key => $value) {
        // ignore s3 "folders"
        if (preg_match("/\/$/", $key)) continue;

        // explode the path into an array
        $file_path = explode('/', $key);
        $file_name = end($file_path);
            $file_folder = substr($key, 0, (strlen($file_name) * -1)+1);
        $file_folder = prev($file_path);

        $s3_url = "https://s3.amazonaws.com/{$bucket_name}/{$key}";

        $data[$key] = array(
            'file_name' => $file_name,
                    's3_key' => $key,
            'file_folder' => $file_folder,
            'file_size' => $value['size'],
            'created_on' => date('Y-m-d H:i:s', $value['time']),
            's3_link' => $s3_url,
            'md5_hash' => $value['hash']);
    }
    return $data;
}

它返回一个数组，键是完整的文件名，所以你可以这样做：

$list = $this->your_model->list_s3_bucket($bucket_name);

foreach ($list as $key => $row){
   force_download($this->s3->getObject($row['s3_key']), $row['file_name']);
   // you can use this url:
   print($row['s3_link']);
}

function force_download($data, $file_name)
{
      header("Content-type: application/octet-stream");
      header("Content-Disposition: attachment; filename=\"{$file_name}\"");
      echo $data;
}
