如果桶不存在则创建桶

Question

我想检查是否存在特定的存储桶，如果不存在则创建新的存储桶。

我需要知道如何使用 aws.phar + php 检测存储桶是否已经存在

这是伪代码

$bucket = 'my-bucket';

//some code to detect if bucket name 'my-bucket' exists *suggest here*
//$myBucketExists = $client->someMethode()

if(!$myBucketExists){

      $result = $client->createBucket(array(
         'Bucket' => $bucket
      ));

      // Wait until the bucket is created
      $client->waitUntil('BucketExists', array('Bucket' => $bucket));
}
// rest of the code using the bucket

Answer 1

使用headBucket()

$myBucketExists = $client->headBucket( array('Bucket' => $bucket) );
