我正在尝试从 Lambda 触发器上的 S3 逐行读取文件。 下面是我的代码
import boto3
def lambda_handler(event, context):
"""Read file from s3 on trigger."""
s3 = boto3.client("s3")
if event:
file_obj = event["Records"][0]
bucketname = str(file_obj['s3']['bucket']['name'])
filename = str(file_obj['s3']['object']['key'])
print("Filename: ", filename)
fileObj = s3.get_object(Bucket="aws-lambda-hive-trigger", Key=filename)
print(fileObj)
file_content = fileObj["Body"].read().split(b'n')
for lines in file_content:
print(lines)
return 'Thanks'
我没有收到任何错误，但是当我检查云监视日志时，没有打印任何内容。 我应该如何获取文件内容。 以下是我的文件文本：-

这是一个文件的示例，我的文件大小是28 mb， 我没有收到任何错误，但是当我检查 cloudwatch 日志时，没有为大文件打印任何内容 我应该如何获取文件内容。我正在云监视中打印较小文件的文件内容，但是当我上传 28 MB 的实际原始文件时，我无法看到任何文件内容在 cloudwatch 中打印，并且它说在 3 秒后超时。
3s 的超时太短，无法正常工作。传输 28 Mb 将花费更多时间，假设您已为函数提供最小内存。
将超时增加到 30 秒，然后重试。您可以监控通过 Cloudwatch 处理函数所需的时间，以便根据需要增加或减少超时。
