位置和有效 URI 有什么区别

我刚刚在AWS上创建了一个名为 ghazals-ghulam-ali 的存储桶，作为回报，我得到了 2 个 URL：

Location : http://ghazals-ghulam-ali.s3.amazonaws.com/
EffectiveURI : https://s3-us-west-2.amazonaws.com/ghazals-ghulam-ali

Location和EffectiveURI有什么区别？两者对我有什么用处？

我使用以下AWS PHP SDK创建了存储桶：

public function create_bucket($user_id) {
    try {
        $this->s3Client = new S3Client($this->options);
        $isBucketCreated = $this->s3Client->createBucket(array(
                'Bucket' => _global::bucketNamePrecursor.$user_id
        ));
    }catch(Exception $exc){
        $isBucketCreated = false;
    }
    return $isBucketCreated;
}

echo $isBucketCreated的值：（存储桶名称：ghazals-noor-jahan）
