Download image file from s3

Session api by passing the access key and the secret access key. Boto3 looks at various configuration locations until it finds the configuration values such as settings. If you do not want to create a session and access the resource, you can create an s3 client directly by using the following command. Use the below script to download a single file from S3 using Boto3 Resource. Create necessary sub directories to avoid file replacements if there are one or more files existing in different sub buckets.

Then download the file actually. You cannot download folder from S3 using Boto3 using a clean implementation. So far we created our IAM user and our S3 bucket with an images folder. It should look like the picture below: 3.

Now we need to attach the policy to the user. As written earlier, I am using expressjs as a back-end, however the code below can easily be adapted to other alternatives.

My client-side is implemented in React-Native. To allow the user to select a picture and send it to our S3 bucket we will use the ImagePickerIOS component which is not very highly documented…. Put the code below on your RN app wherever you want it to be run. I adapted the original code that I found in this very helpful article. You can download one file at a time. You will have to use the CLI method to download multiple files.

As you can see in the picture below, when I select multiple files the download button gets disabled. You can try the below steps and see if it works for you. These steps did not work for me but I have seen these working for others.

You can definitely try. Note - If you are wondering, let me tell you that you do not need to specify any region in the below commands. To download the files as per your requirements, you can use the following command -.

To download the files one from the images folder in s3 and the other not in any folder from the bucket that I created, the following command can be used -. 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. Adrian Tofting Adrian Tofting 1 1 silver badge 6 6 bronze badges. BytesIO client.
