Python 正在获取boto.exception.S3ResponseError:S3ResponseError:400错误请求异常

我正在尝试使用boto下载S3存储桶中存在的日志文件。不使用s3cmd和其他一些工具的原因是，我不希望我的代码依赖于某种软件/工具，这样其他人也可以直接使用我的代码，而不必担心下载其他依赖项

我得到以下堆栈跟踪。我看到了各种相关的帖子，但都没有解决我的问题

boto.exception.S3ResponseError: S3ResponseError: 400 Bad Request

解决的问题： 在S3日志存储桶中，我提到了特定于我的存储桶的整个路径。。就像我有我的水桶，里面有多个文件夹。所以我提到了通往它的整个道路，但博托并不认为这会发生。因此，我只需提及bucket名称，而不必提及整个路径

以前我在做-->

正确的做法-->

from fabric.api import task
from fabric.api import env

S3_LOG_BUCKET = BUCKET-NAME


class S3(object):
    s3_conn = None
    log_bucket = S3_LOG_BUCKET
    region = region
    bucket = None
    env.host_string = REGION-NAME

    def __init__(self):
        self._s3_connect()
        self.bucket = self._get_bucket(self.log_bucket)

    def _s3_connect(self):
        if not self.s3_conn:
            self.s3_conn = boto.s3.connect_to_region(
                self.region,
                aws_access_key_id=AWS_ACCESS_KEY_ID,
                aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
            )
        if not self.s3_conn:
            raise ValueError('Invalid Region Name: {}'.format(region))

    def download_s3_logs(self):
        for l in self.bucket.list():
            key_string = str(l.key)
            l.get_contents_to_filename("/tempLogFiles/" + key_string)
            print l.key

    def _get_bucket(self, bucket):
        return self.s3_conn.get_bucket(bucket)


@task
def dlogs():
    s3 = S3()
    s3.download_s3_logs()

log_bucket = Bucket/Inner Folder 1/Inner Folder 2/.../ which was wrong

log_bucket = Bucket
