AccessDenied 정책에 따라 잘못되었습니다 : 정책 조건이 실패했습니다 : [ "starts-with", "$ key", "2017 /"]

제목에 지정된 오류가 발생합니다.

내가 수행하려고 : PHP

문제와 체결 URL을 업로드 개체 보인다 여기 : ['starts-with', '$key', 'test/']

['starts-with', '$key', 'test/'] 어떻게 이런 일을합니까?

버킷 테스트 폴더에 있습니다.

도와주세요.

내 코드 (서버 측 PHP) :

$formInputs = ['acl' => 'private']; 

// Construct an array of conditions for policy $options = [ 
    ['acl' => 'private'], 
    ['bucket' => $bucket], 
    ['starts-with', '$key', 'test/'] ]; 

// Optional: configure expiration time string $expires = '+2 hours'; 

$postObject = new \Aws\S3\PostObjectV4(
    $client, 
    $bucket, 
    $formInputs, 
    $options, 
    $expires); 

$formAttributes = $postObject->getFormAttributes(); $formInputs = $postObject->getFormInputs(); 

?> 


---------- 


<form action="<?=$formAttributes['action']?>" method="<?=$formAttributes['method']?>" enctype="<?=$formAttributes['enctype']?>"> 

<?php 

    foreach($formInputs as $k=>$v){ 
     echo'<input type="hidden" name="'.$k.'" value="'.$v.'" ><br>'."\r\n"; 
    } 
    ?> 
    <input type="file" name="file"> 
    <input type="submit" name="upload s3"> 
</form>
