问题 I'm trying to upload to an Amazon s3 bucket using knox in a nodejs project but can't get past a 403 error. I've ensured that the key,secret, and bucket are properly set. I could really use some help here from those with more experience. My node code is as follows: var upload_test = function(){ var client = knox.createClient( { key: config.aws.key , secret: config.aws.secret , bucket: config.aws.bucket } ); fs.readFile('test.pdf', function(err,buf){ var req = client.put('6530/test.pdf', {

问题 I am currently using the Ruby aws-sdk, version 2 gem with server-side customer-provided encryption key(SSE-C). I am able to upload the object from a rails form to Amazon S3 with no issues. def s3 Aws::S3::Object.new( bucket_name: ENV['S3_BUCKET'], key: 'hello', ) end def upload_object customer_key = OpenSSL::Cipher::AES.new(256, :CBC).random_key customer_key_md5 = Digest::MD5.new.digest(customer_key) object_key = 'hello' options = {} options[:key] = object_key options[:sse_customer_algorithm]

问题 Amazon S3 provides an "eventual consistency" model, where data you store is eventually visible to all clients. I can't find any official information as to whether write ordering is guaranteed or not. This is fundamentally important if you are building an architecture where a client might want to read data right after someone else stored it. If write ordering is preserved, I can easily check whether the data is complete by having the writer store a guard (say, a special key) and the end of the

问题 I built a website using ReactJs, and to see the website, I generally do npm start and go to localhost:3000 via a browser. I now want to host this website on S3, but without an EC2 instance. My understanding is that npm is a process, so it is server-side, and therefore, I would need to purchase compute to actually deploy my website. I found this tutorial that does not mention paying for EC2 instance compute time: https://www.fullstackreact.com/articles/deploying-a-react-app-to-s3/ However,
