我正在嘗試選擇一個現有存盤桶，然后使用 Boto3 將檔案上傳到存盤桶中。但是與存盤桶相關的所有方法對我來說都無法正常作業。
我面臨的問題是這樣的：
- 當我使用
boto3.Session.client('s3').list_buckets()方法列出存盤桶時，它會生成一個空的存盤桶串列。 boto3.Session.resource('s3').Bucket('existing_bucket_name')當我使用then runupload_fileobj()方法選擇特定的存盤桶時，它會拋出例外（盡管 Bucket 物件的屬性正確回傳了存盤桶的名稱NoSuchBucket，這非常荒謬）。name
到目前為止我已經嘗試過：
- 使用
Session帶有關鍵字引數的實體，指示帳戶和區域配置。我在 Boto3 配置設定方面遇到了一些問題，最終放棄了使用組態檔，然后直接提供了實體配置引數。 resource代替client. _client方法不能正常作業，所以我用resource了，但也不順利。
這是我的代碼：
- 實作客戶端類
class S3Client:
def __init__(self):
region = 'ap-northeast-2'
self.session = boto3.Session(
aws_access_key_id=os.environ['AWS_ACCESS_KEY_ID'],
aws_secret_access_key=os.environ['AWS_SECRET_ACCESS_KEY'],
region_name=region
)
self.client = self.session.client(service_name='s3', region_name=region,
aws_access_key_id=os.environ['AWS_ACCESS_KEY_ID'],
aws_secret_access_key=os.environ['AWS_SECRET_ACCESS_KEY'])
self.resource = self.session.resource('s3')
self.bucket = self.resource.Bucket(settings.AWS_S3['BUCKET_NAME'])
@staticmethod
def open_test_file_as_byte():
file_name = os.path.join(os.path.dirname(__file__), 'test_file.pdf')
data = open(file_name, 'rb')
return data
def upload_file(self, file_name):
with self.open_test_file_as_byte() as file_byte_stream:
return self.bucket.upload_fileobj(
file_byte_stream,
'reports/' file_name,
ExtraArgs={'ACL': 'public-read-write'}
)
# this method worked once with message saying that creation successfully completed, but I cannot find anything in my S3
def create_bucket(self):
return self.client.create_bucket(
ACL='public-read-write',
Bucket='public-reports'
# CreateBucketConfiguration={
# 'LocationConstraint': 'ap-northeast-2'
# }
)
- 呼叫客戶端方法的代碼
@mock_s3
class S3ClientTestCases(unittest.TestCase):
@classmethod
def setUpClass(cls) -> None:
cls.s3_client = S3Client()
def test_create_bucket(self):
logger.debug(self.s3_client.create_bucket())
logger.debug(self.s3_client.client.list_buckets())
def test_upload_file(self):
logger.debug(self.s3_client.upload_file('test.pdf'))
這是完整的錯誤日志：

我猜 AWS 帳戶設定有問題，但我不確定到底是什么導致了整個故障......
請任何建議！
uj5u.com熱心網友回復：
解決了
我的問題的原因是測驗代碼上的注釋，@mock_s3.
實際上，我什至不能稱之為問題，而是一個錯誤。
不管怎樣，如果有人因為那個注釋而遇到麻煩，我希望我的愚蠢記錄能幫到你。
