pre-signed-url

问题 I tried if I use access key, it works fine but I am trying to get ride of access key and using role instead, but once I get ride of access key. what I get in return is www.aws.amazon.com const AWS = require('aws-sdk'); const s3 = new AWS.S3(); const params = {Bucket: config.bucket, Expires: config.time, Key}; const url = s3.getSignedUrl('getObject', params); console.log('The URL is', url); I even made sure my role is set right by going into my ec2 and run the cli command aws s3 presign s3:/

问题 I'm using S3 pre-signed url for uploading images directly from client-side. I would like to be able to push a message to SQS queue only when I'm sure that the url was used and a new image was uploaded. Given a pre-signed url, how can I validate if it was used? 回答1: Do you really need to know when a pre-signed URL has been used? Or can you just send a new message to SQS whenever a new object is uploaded to your S3 bucket? Since you are restricting uploads to using pre-signed URLs wouldn't that

问题 I'm using Node to get an presignedRUL for S3 in order to PUT an image to an S3 bucket. var aws = require('aws-sdk'); // Request presigned URL from S3 exports.S3presignedURL = function (req, res) { var s3 = new aws.S3(); var params = { Bucket: process.env.S3_BUCKET, Key: '123456', //TODO: creat unique S3 key //ACL:'public-read', ContentType: req.body['Content-Type'], //'image/jpg' }; s3.getSignedUrl('putObject', params, function(err, url) { if(err) console.log(err); res.json({url: url}); }); }

问题 I am getting a presigned url from aws and using it to request(PUT) a zip file. I get signature does not match. when getting presigned url: const params = { Bucket: myBucket, Key: myKey, Expires: 60*60, ACL: '**-**-**', ContentType: 'application/x-zip-compressed'}; when requesting: const formData = new FormData(); formData.append('file', file); formData.append('filename', file.name); fetch(url, { method: 'PUT', headers: { 'Content-Type': 'application/x-zip-compressed', }, body: formData }) 回答1

问题 According to this link http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html, I can easily create a presigned link just adding the life span to getObjectUrl $signedUrl = $client->getObjectUrl($bucket, 'data.txt', '+10 minutes'); // > https://my-bucket.s3.amazonaws.com/data.txt?AWSAccessKeyId=[...]&Expires=[...]&Signature=[...] But I get a plain url, you know, without the awsaccesskeyid and expires parameters, Here's my code: $bucket = 'imagenesfc'; $keyname = 'NASimagenes

问题 I am trying to use signed url to upload images to s3 bucket. Following is my bucket policy: { "Version": "2012-10-17", "Statement": [ { "Sid": "", "Effect": "Allow", "Principal": { "AWS": [ "arn:aws:iam::12345678:user/myuser", "arn:aws:iam::12345678:root" ] }, "Action": [ "s3:List*", "s3:Put*", "s3:Get*" ], "Resource": [ "arn:aws:s3:::myBucket", "arn:aws:s3:::myBucket/*" ] } ] } I am generating the signed url from the server as follows: var aws = require('aws-sdk'); aws.config = { accessKeyId

问题 I would like to do a pre-signed POST to upload files to an AWS S3 bucket - how would this be done in Go? Please note that this is not the same as Pre-signed upload with PUT. 回答1: So in order to help others I will answer the question myself and provide some code to help others who might have the same problem. Example web app for Google App Engine rendering a pre-signed POST form can be found here. And a small library I created doing the pre-signed POST in Go. In short, doing a presigned POST

问题 Consider the following code: OkHttpClient client = new OkHttpClient(); MediaType mediaType = MediaType.parse("text/plain; charset=utf-8"); // [A] RequestBody body = RequestBody.create(mediaType, media); String[] aclHeader = "x-goog-acl:public-read".split(":"); Request request = new Request.Builder() .addHeader("Content-Type", "text/plain") // [B] .addHeader(aclHeader[0], aclHeader[1]) .url(url) .put(body) .build(); Response response = client.newCall(request).execute(); I am accessing GCS from

问题 I am trying to assume an IAM role and then use Amazon S3 by generating a presigned URL in order to access an S3 bucket in it. This is how I have configured my code in Python : def create_dynamicurl(key, expiration): client = boto3.client('sts') assumed_role_object = client.assume_role(DurationSeconds=3600,RoleArn='arn:aws:iam::123456789555:role/sample-S3AssumeRole',RoleSessionName='sampleSession',) temp_credentials = assumed_role_object['Credentials'] s3_resource = boto3.resource('s3' , aws
