Using Postman scripting, how to download the file from AWS S3 bucket
That's not possible,
Because in the browser download it's not just a direct 1 chunk
so it's creating a synchronous stream job which load chunk after another and such a system is not supported by postman

I have a versioning enabled bucket in GCS.
The application I'm working on uses the AWS S3 .NET SDK to connect to a S3-compatible object storage and has been working just fine for this use case.
Now we're also about to support GCS object storage. From my research and testing, GCS offers S3-compatibility through their XML-api. I've tested this and sure enough, GetObject/PutObject/multipart uploads/chunked downloads are all working fine with the code using the S3 library.
However, the compatibility seems to stop when I tried testing the versioning feature: our application makes heavy use of object storage versioned buckets, requesting non-current versions by their VersionID.
With the S3 library connecting to the S3 object storage, everything works fine: PutObject and multipart uploads (= CompleteMultipartUpload response) return the VersionID properly.
For GCS though, this does not return their version of a "VersionID" (= the object Generation).
Response looks like this:
I would have expected that GCS returns this Generation as the VersionID in these responses, since they are conceptually the same. But as you can see, VersionID is null (and the bucket is definitely versioning-enabled).
I would just write another implementation class that uses the GCS .NET SDK, but our application heavily relies on chunked uploading where we retrieve a chunk of data from an external source one by one (so we don't have the full Stream of data). This works well with S3's multipart upload (each chunk is uploaded in a separate UploadPart call), but GCS resumable upload expects a Stream that just has all the data right away. So it looks like we really need multipart upload functionality, that we can use through the S3 library with GCS's XML API. If anyone has suggestions on how to make this work with GCS whereby we can upload chunk per chunk in separate calls to construct an object like multipart upload, would also be greatly appreciated.
So my questions are: will receiving the VersionID after uploading just not work with the AWS S3 SDK to Google Cloud Storage or am I doing it wrong? Do I have to look elsewhere in the response for it? Configure some setting to get this properly returned?
I want to generate a presigned URL for an S3 bucket, and upload files using the url, not through nuxeo server or the direct upload option.
The documentation, says, that I need to set the CloudFrontBinaryManager as the binary manager to be used. Despite, setting the configuration in nuxeo.conf, I am not able to upload directly to the bucket. I still see the request made to /upload, which routes the upload through the nuxeo server to the s3 bucket.
The downloads happen through the presigned url, but the upload doesn't. How can I make the upload work?
But is a bit of a random question and no one should ever do it this way, but is it possible to execute a put api call to amazon S3 from the web browser? Using only query params.
For instance, ignoring authentication params, I know you can do https://s3.amazonaws.com/~some bucket~
To list files in the bucket. Is there a way to upload?
Have look at Browser-Based Uploads Using POST
I am developing a website in HTML, javascript & jQuery. I want to upload (multiple images) to amazon s3 server in an ajax request. There is no such SDK to integrate s3 in Javascript. A PHP SDK is available, but it is not useful to me. Can anybody provide solution to this in javascript?
You can read the article - How to Upload Scanned Images to Amazon S3 Using Dynamic Web TWAIN, which introduces how to use PHP and JavaScript to upload files to Amazon S3. Key steps include:
Specify the bucket which is the place or the folder name used for
storing data on Amazon S3
Specify the Access Key and Secret Key you
obtained from your Amazon S3 account
Create a policy that specifies
what you permit and what you don’t permit for the data uploaded from a
client web page
Encode and encrypt these policies and signatures to
keep them confidential, and store the encoded and encrypted values in
the hidden input elements.
Is boto API (python) for amazons3 is streaming upload?
there is another API called Simples3. i think no body is heard of it.
http://pypi.python.org/pypi/simples3
it has a function call for streaming upload. but i would like to use boto if it has streaming upload option.
i know about Multipart in Boto. i dont want to use multipart because i do not want to split the files on disk and have one huge file and splits of it. i believe it's a wastage of space.
What would be the difference between boto and simples3
If by "streaming upload" you mean chunked transfer encoding, then I don't think boto, simples3 or any other package will support it because S3 doesn't support it. Boto has methods for streaming but they are only supported by Google Cloud Storage.
