pre-signed-url

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: myAccessKeyId, secretAccessKey: mySecretAccessKey }; var s3 = new aws.s3(); s3.getSignedUrl(

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. 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 to a public-read Amazon S3 bucket you need to: 1. Configure the S3 bucket to only allow public download.

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 a client, with a previously signed URL. Problem: It seems okhttp adds the charset declared for the

Is there any way that I can generate Pre-Signed URL's without any expiry date ? I'm developing a Email app where my attachments will be saved in S3. Also please let me know what is the best way to download attachments via JavaScript SDK. I'm using below code var params = {Bucket: 'bucket', Key: 'key', Expires: 60}; var url = s3.getSignedUrl('getObject', params); console.log('The URL is', url); yottabytt The maximum expiration time for presigned url is one week from time of creation. So there is no way to have a presigned url without expiry time. 来源： https://stackoverflow.com/questions/24014306

Has anyone successfully used the AWS SDK to generate signed URLs to objects in an S3 bucket which also work over CloudFront? I'm using the JavaScript AWS SDK and it's really simple to generate signed URLs via the S3 links. I just created a private bucket and use the following code to generate the URL: var AWS = require('aws-sdk') , s3 = new AWS.S3() , params = {Bucket: 'my-bucket', Key: 'path/to/key', Expiration: 20} s3.getSignedUrl('getObject', params, function (err, url) { console.log('Signed URL: ' + url) }) This works great but I also want to expose a CloudFront URL to my users so they can

I'm trying to gracefully handle the 403 when visiting an S3 resource via an expired URL. Currently it returns an amz xml error page. I have uploaded a 403.html resource and thought I could redirect to that. The bucket resources are assets saved/fetched by my app. Still, reading the docs I set bucket properties to handle the bucket as a static webpage page and uploaded a 403.html to bucket root. All public permissions are blocked, except public GET access to the resource 403.html. In bucket properties, website settings I indicated the 403.html as error page.
