python - boto3 在通过 python 上传文件时给出拒绝访问错误

Question

当我尝试在 python 中使用 boto3 将图像上传到 s3 时，我不断遇到错误。错误说:

An error occurred (AccessDenied) when calling the PutObject operation: Access Denied

我上传图片的代码是

def upload_file(file_name, bucket, object_name=None):
    """Upload a file to an S3 bucket

    :param file_name: File to upload
    :param bucket: Bucket to upload to
    :param object_name: S3 object name. If not specified then file_name is used
    :return: True if file was uploaded, else False
    """

    # If S3 object_name was not specified, use file_name
    if object_name is None:
        object_name = file_name

    # Upload the file
    s3_client = boto3.client('s3')
    try:
        response = s3_client.upload_file(file_name, bucket, object_name, ExtraArgs={'ACL':'public-read'})
        print(response)
    except Exception as e:
        print(e)
        return False
    return True

Answer 1

解决方案非常简单易行，因为我没有提供 ACCESS_KEY 和 SECRET_KEY，所以 AWS 不允许我将图像上传到 s3。

我在从 boto3 获取 s3 的客户端时添加了访问 key 和 secret key

s3_client = boto3.client('s3', aws_access_key_id=AWS_ACCESS_KEY_ID, aws_secret_access_key=AWS_SECRET_ACCESS_KEY)

存在一个很好的文档 at boto documentation
