问题 I'm following this guide on configuring the AWS SDK in .NET Core to upload a file to an S3 bucket.

问题 DynamoDB's Number type supports 38 digits of decimal precision. This is not big enough to store a 128-bit integer which would require 39 digits. The max value is 340,282,366,920,938,463,463,374,607,431,768,211,455 for unsigned 128-bit ints or 170,141,183,460,469,231,731,687,303,715,884,105,727 for signed 128-bit ints. These are both 39-digit numbers. If I can't store 128 bits, then how many bits of integer data can I store in a Number ? 回答1: DynamoDB attribute of type Number can store 126-bit

问题 I want to delete a file from Amazon S3 using Javascript. I have already uploaded the file using Javascript. Any ideas? 回答1: You can use the JS method from S3: var AWS = require('aws-sdk'); AWS.config.loadFromPath('./credentials-ehl.json'); var s3 = new AWS.S3(); var params = { Bucket: 'your bucket', Key: 'your object' }; s3.deleteObject(params, function(err, data) { if (err) console.log(err, err.stack); // error else console.log(); // deleted }); Be aware that S3 never returns it the object

问题 (new information below) I am trying to set up a lambda function that reacts to uploaded tgz files by uncompressing them and writing the results back to S3. The unzip and untar work fine, but uploading to S3 fails: /Users/russell/lambda/gzip/node_modules/aws-sdk/lib/s3/managed_upload.js:350 var buf = self.body.read(self.partSize - self.partBuffer.length) || ^ TypeError: undefined is not a function at ManagedUpload.fillStream (/Users/russell/lambda/gzip/node_modules/aws-sdk/lib/s3/managed

问题 All that I found, it's this method GET Bucket But I can't understand how can I get only a list of folders in the current folder. Which prefix and delimiter I need to use? Is that possible at all? 回答1: For the sake of example, assume I have a bucket in the USEast1 region called MyBucketName , with the following keys: temp/ temp/foobar.txt temp/txt/ temp/txt/test1.txt temp/txt/test2.txt temp2/ Working with folders can be confusing because S3 does not natively support a hierarchy structure --
