无法使用 boto3 在 aws s3 中创建文件夹

Question

我想创建一组文件夹，我想在其中将我的文件上传到 s3 存储桶中。 但是，我没有得到所需的文件名。 这是我的代码

s3 = boto3.resource('s3')

def upload_to_aws(local_file, bucket, s3_file):
    s3 = boto3.client('s3', aws_access_key_id=ACCESS_KEY,
                      aws_secret_access_key=SECRET_KEY)

    try:
        s3.upload_file(local_file, bucket, s3_file)
        print("Upload Successful")
        return True
    except FileNotFoundError:
        print("The file was not found")
        return False
    except NoCredentialsError:
        print("Credentials not available")
        return False

customer_name = "demo"
date = datetime.now().strftime('%d')
month = datetime.now().month
year = datetime.now().year


stack_path = "/home/ubuntu/pano/stack"    
for file in sorted(os.listdir(stack_path)):
    print(f"Uploading {file}")
    folders_path = f"{customer_name}/{year}/{month}/{date}"
    uploaded = upload_to_aws(f'/home/ubuntu/pano/stack/{file}', 'bucket-name1', '%s/%s' % (folders_path, file))

我希望文件夹是客户名称/年/月/日，我希望在其中上传文件。但是我得到的文件夹是 “顾客姓名/ ” “年/” “月/” “日期/” 我不想要文件夹名称中的反斜杠。我该怎么做？

编辑

我想要的文件夹具有以下路径 - 年/月/日/文件名.txt 但是，正在创建的路径具有以下文件夹名称 年//月//日//文件名.txt

每个文件夹名称都附有一个反斜杠。这些是我在我的存储桶中看到的目录

1. 年/
2. 月/
3. 日期/

我想避免使用反斜杠和名称

这只是表示什么是“文件”或什么是“文件夹”。
但请记住，没有文件夹的概念，它只是一个对象键。

见下文，我正在使用您的代码。成功上传文件到bucket。

Uploading file2

Uploading file3

>>> exit()

现在让我们看看如何获​​取文件。请注意，文件的密钥正是您所期望的，所以不要在上面加倍 /。

来自 AWS CLI。在第一个输出中，您可以看到最后的 /，但这只是一个表示，请查看下面的完整对象键。

$ aws s3 ls s3://test-bucket/demo
                           PRE demo/

$ aws s3 ls s3://test-bucket/demo --recursive
