【问题描述】:
我正在使用 boto3 通过 Lambda Python 函数读取 S3 中的许多文本文件。
我在下面连接到 S3 的代码
config = Config(
read_timeout=900,
connect_timeout=900,
retries={"max_attempts": 0}
)
session = boto3.Session(region_name='ap-southeast-2')
s3 = session.resource('s3', config=config)
bucket = s3.Bucket(bucket)
for obj in bucket.objects.all():
大约30个文本文件成功ok。但之后,它得到以下错误消息
[ERROR] 2021-09-01T09:35:08.628Z 6a5bf649-2057-43e4-a3eb-1b4438e582fb Exception on /process [POST]

有什么办法可以解决这个问题?
【问题讨论】:
-
你的函数在 vpc 中吗?
-
@Marcin 是的。这个问题重要吗?
-
是的,因为 vpc 中的 lambda 没有互联网连接,除非您设置正确。它必须在vpc中吗?如果没有,请将其从 vpc 中删除,它应该可以工作。
-
@Marcin 我在 vpc 中添加 Lambda 的原因是,它必须连接到 Rds 并且 Rds 在 vpc 中。那么还有什么其他方法可以解决这个问题吗?
