使用Lambda将Cloudwatch日志导出到S3

I have some logs in CloudWatch and everyday, I keep getting new logs. Now, I want to store today's and yesterday's logs in Cloud Watch itself but logs that are 2 days older have to be moved to S3.

我在CloudWatch中有一些日志，而且我每天都会收到新日志。现在，我想将今天和昨天的日志存储在Cloud Watch本身，但是2天之前的日志必须移动到S3。

I have tried using the below code to export CloudWatch Logs to S3 :

我尝试使用以下代码将CloudWatch Logs导出到S3：

import boto3
import collections

region = 'us-east-1'

def lambda_handler(event, context):

    s3 = boto3.client('s3')

    response = s3.create_export_task(
        taskName='export_task',
        logGroupName='/aws/lambda/test2',
        logStreamNamePrefix='2016/11/29/',
        fromTime=1437584472382,
        to=1437584472402,
        destination='prudhvi1234',
        destinationPrefix='AWS'
    )

    print response

When I run this, I got the following error :

当我运行它时，我收到以下错误：

'S3' object has no attribute 'create_export_task': AttributeError
Traceback (most recent call last):
  File "/var/task/lambda_function.py", line 10, in lambda_handler
    response = s3.create_export_task(
AttributeError: 'S3' object has no attribute 'create_export_task'

What might the mistake be?

错误可能是什么？

client = boto3.client('logs')

You are accessing logs from CloudWatch and not S3. Hence the error. Subsequently

您正在从CloudWatch而不是S3访问日志。因此错误。后来

response = client.create_export_task(
        taskName='export_task',
        logGroupName='/aws/lambda/test2',
        logStreamNamePrefix='2016/11/29/',
        fromTime=1437584472382,
        to=1437584472402,
        destination='prudhvi1234',
        destinationPrefix='AWS'
    )
