问题 I am trying to set up an app where users can download their files stored in an S3 Bucket. I am able to set up my bucket, and get the correct file, but it won't download, giving me the this error: No such file or directory: 'media/user_1/imageName.jpg' Any idea why? This seems like a relatively easy problem, but I can't quite seem to get it. I can delete an image properly, so it is able to identify the correct image. Here's my views.py def download(request, project_id=None): conn =

问题 I'm using DynamoDB as an K-V db (cause there's not much data, I think that's fine) , and part of 'V' is list type (about 10 elements). There's some session to append a new value to it, and I cannot find a way to do this in 1 request. What I did is like this: item = self.list_table.get_item(**{'k': 'some_key'}) item['v'].append('some_value') item.partial_save() I request the server first and save it after modified the value. That's not atomic and looks ugly. Is there any way to do this in one

问题 I am trying to set metadata during pushing a file to S3.

问题 I cant seem to find a decent example that shows how can I consume an AWS Kinesis stream via Python. Can someone please provide me with some examples I could look into? Best 回答1: While this question has already been answered, it might be a good idea for future readers to consider using the Kinesis Client Library (KCL) for Python instead of using boto directly. It simplifies consuming from the stream when you have multiple consumer instances, and/or changing shard configurations . https://aws
