I was wondering if I can write a javascript to download such a file from a bucket. I was googling it, but couldn't find any resources that can help me do that.
Some steps in mind are: authenticate Amazon S3, then by providing bucket name, and file key , download or read the file so that I can be able to display the data in the file. Maybe you can use AWS Node. As, I can not store my s3 auth keys on client side, I used my server-side scripts to generate a pre-signed url and send it back to client like:.
Was getting url is too long My solution was to include a hidden anchor tag, and trigger the click to that tag on ajax success. You can't use the anchor tag right off the bat unless you don't care about handling errors.
S3 will respond with an XML error file if something goes wrong, so the browser will automatically display that XML response. On success in that ajax call is when you know you're clear to try and download the file. I believe this post helped you solve your problem.

I have In this post, we will be looking at the types of AWS services. I will give you an overview of what s I just want to supply the download URL to S3 and wait for them to download it to their filesystem. It seems like an easy thing to do, but I just can't find the documentation on it.
Much faster than uploading it from your own computer. This way allows you to avoid downloading the file to your computer and saving potentially significant time uploading it through the web interface. So you can create a bucket and configure in your code to fetch data from url and write to this bucket in s3. Obtain the curl command corresponding to the download from your local machine.
This will download and save the file. Configure aws credentials to connect the instance to s3 one way is to use the command aws config , provide AWS access key Id and secret ,. I was facing the same task. However, all the provided answers have one flaw: They save the large file to EC2 disk. So, better avoid saving to disk.

Improve this answer. Thanks for the response. I have also tried the way that you mentioned, but with the same results. Also to consider is if the key is deleted.
