How could I use aws lambda to write file to s3 (python)?
I have tried to use lambda function to write a file to S3, then test shows "succeeded" ,but nothing appeared in my S3 bucket. What happened? Does anyone can give me some advice or solutions? Thanks a lot. Here's my code.
import json import boto3 def lambda_handler(event, context): string = "dfghj" file_name = "hello.txt" lambda_path = "/tmp/" + file_name s3_path = "/100001/20180223/" + file_name with open(lambda_path, 'w+') as file: file.write(string) file.close() s3 = boto3.resource('s3') s3.meta.client.upload_file(lambda_path, 's3bucket', s3_path)
