Install Boto3 using the command sudo pip3 install boto3 If AWS cli is installed and configured you can use the same credentials to create session using Boto3.
Create a generic session to your AWS service using the below code. Use the below command to access S3 as a resource using the session. AWS Region is a separate geographic area. Explained in previous section s3 — Resource created out of the session s3. You can also give a name that is different from the object name.
If your file is existing as a. I'm facing this issue without the "Content-Disposition" parameter defined. James G James G 1, 12 12 silver badges 22 22 bronze badges. Thank you for the Terraform mention! Terraform documentation should have mentioned it. This is exactly what I needed, thank you. Also to add, due to some caches, if one keep retrying the website endpoint, the issue would appear to still exist.
Try doing it in incognito or after clearing caches, it will serve the content on the browser. This is exactly what I was looking for.

This screen looks something like this:. Do note I redacted my access and secret key from the screenshot for obvious reasons but you should have them if everything worked successfully.
Now that we have an access and secret key and our environment setup we can start writing some code. Before we jump into writing code that downloads uploads and lists files from our AWS bucket we need to write a simple wrapper that will be re-used across our applications that does some boiler plate code for the boto3 library.
One thing to understand here is that AWS uses sessions. Similar to when you login to the web console a session is initiated with a cookie and everything in a similar way this can be done programmatically. So the first thing we need to do before we start accessing any resource in our AWS environment is to start and setup our session.
In order to do that we will leverage the library we installed earlier called dotenv. The reason we will use this is to access our secret and access key from the environment file. We use an environment file for security reasons such as avoiding to hardcode any values in our code base.
The environment file basically tells Python that the data will live in the process environment which is in memory and does not touch any source file. In a way this is similar to setting environment variables in your terminal but for convenience we set them in our.
The format of this would look something like this:. The data values above have been randomized for obvious reasons. But as you can see we are setting two variables here one for our access and one for our secret key which our code will be reading from in order to use them to initialize our AWS session. This can be seen in the code below:. Now that we have our keys setup we will talk about how to upload a file using Boto3 S3.
We will start by uploading a local file to our S3 bucket. The code we will be writing and executing will leverage the boto3 helper python code we wrote above. The steps to accomplish this are the following:.
One thing to note here is that we are uploading 2 files test. This assumes you have created the files locally if not you can use the ones from the git repo and you need to have created a bucket as it was shown earlier called unbiased-coder-bucket.
If you choose a different name just replace the code above accordingly with the bucket name you chose to use. If we were to execute the code above you would see it in the output:. Close Menu.

But wait Open the S3 console Click on the bucket from which you want to download the file Select all the files which you want to download and click on Open.
Look at the picture below. I guess there is a limit in Chrome and it will only download 6 files at once. Download single file To download a single file follow the below steps - Open the S3 console Click on the bucket from which you want to download the file Select the file that you want to download and click on the download button Using the AWS CLI Note - If you are wondering, let me tell you that you do not need to specify any region in the below commands.
Conclusion I believe this post helped you solve your problem. Thank you and keep learning. Let's make a deal Deal. Want to gain more knowledge for free? AWS types of services Learning AWS?
