从 amazon s3 存储桶对象获取图像 url

Question

//story image to s3 bucket
    try {
        $s3->putObject([
                'Bucket' => $config['s3']['bucket'],
                'Key' => "uploads/{$name_of_uploaded_file}",
                'Body' => fopen($path_of_uploaded_file, 'rb'),
                'ACL' => 'public-read'
            ]);
        //remove the file
        unlink($path_of_uploaded_file);
    } catch(S3Exception $e){
        die("there was an error");
    }

    //retrieve image url
    $objects = $s3->getIterator('ListObjects', [
      'Bucket' => $config['s3']['bucket']
    ]);
    //put img url into variable so that it stores it into sql table
    $photoLink = $s3->getObjectUrl($config['s3']['bucket'], $objects['Key']);


if (is_uploaded_file($_FILES['uploaded_file']['size'])){
        //send items to pending database

            //note already connected to db

          //inserts in pending db
          $sql = "INSERT INTO pending (id,photo,title,description,name) VALUES ('', :photo, :title, :description, :name)";
          $stmt = $conn->prepare($sql); 
          $stmt->bindParam(':title', $title);
          $stmt->bindParam(':photo', $photoLink);
          $stmt->bindParam(':description', $story);
          $stmt->bindParam(':name', $first_name);
          $stmt->execute();       
    }else {
      header('Location:index.php');
    }

如何让 php 提取 url 以便它存储 ex: http://www.amazonaws/bucket/image.jpg 到我的 sql 数据库列照片中？

现在我的网络应用程序给我这个错误：不能在第 127 行

中将类型 Aws\S3\Iterator\ListObjectsIterator 的对象用作数组

Answer 1

//retrieve image url
$objects = $s3->getIterator('ListObjects', [
  'Bucket' => $config['s3']['bucket']
]);

这不是您认为的那样。正如方法名称所暗示的那样，这为您提供了一个迭代器，而不是内存数组。此迭代器将覆盖存储桶中的每个项目，而不仅仅是您上传的文件。由于它是一个迭代器，当您尝试使用数组访问方法 ($photoLink = $s3->getObjectUrl($config['s3']['bucket'], $objects['Key']);) 时，它会爆炸。

您可能想要的是来自 putObject() 的响应，您目前没有存储它。类似于：

try {
    $result = $s3->putObject([
<snip>

之后，您可以使用 $result['ObjectURL'] 访问 URL。来自 putObject() is on Amazon's site.
