Download files from s3 bucket flask form

And then we include the two files from the excluded files. Let us say we have three files in our bucket, file1, file2, and file3. And then with the help of include, we can include the files which we want to download. Example - --include "file1" will include the file1.

To download the entire bucket, use the below command -. The above command downloads all the files from the bucket you specified in the local folder.

As you may have noticed, we have used sync or cp in the above commands. Just for your knowledge, the difference between the sync and cp is that the sync option syncs your bucket with the local folder whereas the cp command copies the objects you specified to the local folder.

For our purpose to download files from s3 we can use either one of sync or cp. I believe this post helped you solve your problem.

Yeah, this is the result of my first attempt at Without getting into too many details, let us first take a quick look at what may be the mistake tha So without a further due, let us look at my recommendations for a beginner getting into AWS.

I have In this post, we will be looking at the types of AWS services. Let's build a Flask application that allows users to upload and download files to and from our S3 buckets, as hosted on AWS.

We will use the Boto3 SDK to facilitate these operations and build out a simple front-end to allow users to upload and view the files as hosted online. It is advisable to use a virtual environment when working on Python projects, and for this one we will use the Pipenv tool to create and manage our environment. Once set up, we create and activate our environment with Python3 as follows:. We now need to install Boto3 and Flask that are required to build our FlaskDrive application as follows:.

After setting up, we need to create the buckets to store our data and we can achieve that by heading over to the AWS console and choosing S3 in the Services menu.

We will use these names to download the files from our S3 buckets. With our S3 interaction file in place, we can build our Flask application to provide the web-based interface for interaction.

The application will be a simple single-file Flask application for demonstration purposes with the following structure:. On our FlaskDrive landing page, we can download the file by simply clicking on the file name then we get the prompt to save the file on our machines. In this post, we have created a Flask application that stores files on AWS's S3 and allows us to download the same files from our application.

We have eliminated the need for us having our own servers to handle the storage of our files and tapped into Amazon's infrastructure to handle it for us through the AWS Simple Storage Service. However with larger files, this well affect UX. The file will need to be completely downloaded to the server, then download to the user. This will download the file in 1MB chunks and send them to the user as they are downloaded. Both of these have been tested with a 40MB. A better way to solve this problem is to create presigned url.

This gives you a temporary URL that's valid up to a certain amount of time. It also removes your flask server as a proxy between the AWS s3 bucket which reduces download time for the user.

If it's through a browser, then you should make a new endpoint to download the file, and provide a link to the endpoint in your app.
