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. 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.

Find centralized, trusted content and collaborate around the technologies you use most. Connect and share knowledge within a single location that is structured and easy to search. I have an iOS app that calls a AWS Lambda function. I would like the Lambda function to get some files from a server and send it back to the iOS app, through the Lambda proxy feature. I am directly invoking the Lambda function from my app using the generated SDK. I couldn't find a documentation explaining how to exchange data other than JSON encoded requests. To return text data from Lambda, you have to return it as a string, and deserialize the string from the JSON response. To return binary data from Lambda, the data must be first transformed encoded using an encoding that cannot ever produce a series of bytes that is not also a valid sequence of UTF-8 characters, because JSON cannot serialize non-character data and not every possible combination of bytes corresponds to a valid character or characters.
The common strategy for doing this is to use base encoding. Base losslessly converts a series of bytes octets into a different series of bytes that are also always valid 7 bit ASCII characters, using an conversion ratio coding 6 bits per byte. You would then need to decode this data back from base to binary. You can do this decoding of JSON and base on the client, but there are also a couple of other options, if you don't like that idea. Both API Gateway and CloudFront's Lambda Edge feature provide a built-in conversion capability to convert the base payload from the JSON Lambda response back to binary, if you don't want to do it on the client.
API Gateway supports all Lambda runtimes, and expects this format Lambda Edge supports only Node. js Lambda functions, but is less expensive than API Gateway. It expects a base response to include The viability of either approach depends on your security needs. API Gateway supports authentication via IAM as well as other mechanisms. If the "files" you mentioned are coming from a server, API Gateway can also proxy these files directly from the server, without a Lambda function handling the content though depending on your security needs, a Lambda Custom Authorizer might be desirable, to authenticate the request but then simply tell API Gateway to allow the request to be forwarded to the backend.
Or, if the files are objects from S3, then you can access S3 directly, similiar to the way you are accessing Lambda, now.

Yes, thar could be done, as long as the response is within the size limits of Lambda and the service calling Lambda. Lambda limits the size of the entire response JSON object to 6MB , which is smaller than the limit of API Gateway but larger than the limit of Lambda Edge. Sign up or log in Sign up using Google.
