由 北城余情 提交于 2021-01-29 12:52:50
问题 I want to use boto2 (2.49) to create a presigned url that uses Sign v4. Here is my function: c = S3Connection(access_key, secret_key) return c.generate_url_sigv4( expires_in=long(expiry), method='PUT', bucket=bucket, key=path ) When I run it, I got this error: 2019-06-18 12:57:51,002 boto [DEBUG]:Using access key provided by client. 2019-06-18 12:57:51,002 boto [DEBUG]:Using secret key provided by client. Traceback (most recent call last): File "scripts/gen_url.py", line 42, in <module> main

S3 Python Download with Progress Bar

由 ≯℡__Kan透↙ 提交于 2021-01-29 08:55:09
问题 Couldn't comment on the initial thread where I adapted this code (Track download progress of S3 file using boto3 and callbacks) so hopefully someone can help me here. I was able to use this code to show a progress bar for file uploads, now I need the do the same thing for file downloads from AWS S3. Any help would be GREATLY APPRECIATED! I know I need to get the size of the file from S3 instead of from the local file system. I'm sure there is some silly code I need to adjust to make this work

Running python with boto2 as an AWS Lambda function

由 十年热恋 提交于 2021-01-28 07:29:02
问题 I am using a python script from github to run on AWS lambda. I realized that the import boto statements are not working while running inside lambda. Is there way to instruct lambda to load boto2 as well? 回答1: OK, all I had to do was install boto using "pip install module-name -t /path/to/project-dir" per the docs: http://docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html Then zipped the files needed for lambda and uploaded. 来源： https://stackoverflow.com

Python - creating aws lambda deployment package

问题 I want to script updating code for my AWS Lambda using a Fabric task. Boto3 api expects a byte array of base-64 encoded zip file. What would be the simplest way to create it assuming I have the source code files as the input? 回答1: With the current boto3, don't unzip it, don't base64 encode it. You can do it with an open and a read like this: import boto3 c = boto3.client('lambda') c.create_function({ 'FunctionName': 'your_function', 'Handler': 'your_handler', 'Runtime': 'python3.6', 'Code': {

How to get messages receive count in Amazon SQS using boto library in Python?

由 孤者浪人 提交于 2020-12-29 04:13:06
问题 I am using boto library in Python to get Amazon SQS messages. In exceptional cases I don't delete messages from queue in order to give a couple of more changes to recover temporary failures. But I don't want to keep receiving failed messages constantly. What I would like to do is either delete messages after receiving more than 3 times or not get message if receive count is more than 3. What is the most elegant way of doing it? 回答1: There are at least a couple of ways of doing this. When you

How to gzip while uploading into s3 using boto

由 ぐ巨炮叔叔 提交于 2020-12-01 09:25:29
问题 I have a large local file. I want to upload a gzipped version of that file into S3 using the boto library. The file is too large to gzip it efficiently on disk prior to uploading, so it should be gzipped in a streamed way during the upload. The boto library knows a function set_contents_from_file() which expects a file-like object it will read from. The gzip library knows the class GzipFile which can get an object via the parameter named fileobj ; it will write to this object when compressing
