kandi X-RAY | aws4 Summary

aws4 is a JavaScript library typically used in Server, Runtime Evironment, Nodejs applications. aws4 has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i @yannvr/aws4' or download it from GitHub, npm.

A small utility to sign vanilla Node.js http(s) request options using Amazon's AWS Signature Version 4. If you want to sign and send AWS requests in a browser, or an environment like Cloudflare Workers, then check out aws4fetch – otherwise you can also bundle this library for use in older browsers. The only AWS service that doesn't support v4 as of 2020-05-22 is SimpleDB (it only supports AWS Signature Version 2). It also provides defaults for a number of core AWS headers and request parameters, making it very easy to query AWS services, or build out a fully-featured AWS library.

Answered 2022-Apr-09 at 21:26

You have your crypto.HmacSHA256 parameters reversed. They should all be the other way around. I've been bashing my head against a wall trying to get evaporate 2.x to work for the last week, it's been very frustrating.

I tried your code above and looked over all the docs and forum posts related to this, and I think using Cognito for this auth just doesn't work or isn't obvious how it's supposed to work, even though the AWS docs suggest it's possible.

In the end I went with using Lambda authentication and finally got it working after seeing much misinformation about how to use various crypto libraries to sign this stuff. I got it working last night after rigorously examining every bit of what was going on. Reading the docs also helped get me on the right path as to how the crypto needs to work, it gives example inputs and outputs so you can test for sure that your crypto methods are working as AWS expects them to work:

https://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html

Tasks 1, 2 and 3 are especially important to read and understand.

how to resolve java.io.FileNotFoundException when trying to get inputstream from AWS url

Asked 2022-Feb-22 at 05:08

my main goal is to get the orientation of a image which I get from AWS, part of the code is to first get the imputStream for which I need to pass the URI, I am doing Uri.parse(url) to get the uri and when I try to get URI I get

ANSWER

Answered 2022-Feb-21 at 20:43

openInputStream() on ContentResolver does not support http or https URLs, only file, content, and android.resource Uri values. You need to use an HTTPS API for your URL, such as OkHttp.

It's possible to rotate an object in gnuplot?

Asked 2022-Feb-03 at 21:33

I'm using software that uses Gnuplot language to plot some data, but I've never used Gnuplot before.

So I was trying to place labels and rectangles in a way that created a nice and readable text, which wasn't bad (as you can see with the number 182 in the image below), but I wanted to learn how to rotate the rectangle and label so that they line up with the white line.

(I can't post images, but it's like that in this link Right now, it looks like:

)

I've already learned to rotate the label (as you can see the number 171), but apparently, it doesn't work the same way with the object.

ANSWER

Answered 2022-Feb-03 at 21:33

Check the following example and help labels. You can create a datablock and add your labels and plot them rotated and boxed together with your map.

Edit: ...forgot the semitransparent boxes. You need to play with the alpha channel, i.e. 0xAARRGGBB.

Ceph/Rados AWS S3 API Bucket Policy via CURL

Asked 2022-Feb-02 at 09:09

I am currently struggling with a problem I am having with rest calls to an AWS s3 API hosted by a rados/ceph gateway.

For reasons I wont go into, I can't use an SDK that is provided to talk to it, which would solve all of my woes - I'm recreating some of the more simple jobs I need via CURL - which in the most part work, I can make buckets, delete them, add objects, create roles but my newest problem is bucket policies, both GET for them and PUT. I receive a 403 every time and I cannot figure out why.

What I have attempted to do is use another box with an SDK that talks to the API (boto3) and the AWS s3API calls to do the same thing and they work perfectly fine with the users Access and Secret key, so I do not think its an account thing.

Using the logs from the SDK jobs, I have attempted to recreate everything that is being sent, headers, payload etc...

Now I can only think that as a 403 maybe its the Auth4 strategy but .... this strategy works for every other job I need to do.

Code:

ANSWER

Answered 2022-Feb-02 at 09:09

Managed to solve my own issue. Noticed in the ceph logs (not sure how I missed it first time round) that the signature from my client didnt match how the ceph radosgw was signing the same signature.

Took it back to task on the canonicalRequest and for some reason if i take out all the line breaks (\n), it calculates.... But all of my other jobs like updating roles, adding buckets etc... fail as they need the line breaks. Not sure why, some Ceph weirdry?

I did packet captures and stripped the SSL to see what both requests from a working SDK and my curl were sending and it was identical...

Oh well, working :)

As indicated by the OP, the use of the url.parse method is discouraged in favor of the WATWG URL API. The legacy .path attribute returns the combined pathname and search components. Although the preferred WATWG URL API does not have the path attribute, the value required by options.path can be constructed by combining the .pathname and .search attributes.

I've solved it now. There were a number of problems aside from my lazy hard coding.

CanonicalURI should just be '/'. - thanks @AlwayLearning.
Changed all string variables to VARCHAR rather than NVARCHAR, this was causing incorrect hashing.
The date used for the @datekey also needs to be a VARCHAR CONVERT(VARCHAR(MAX),FORMAT(@dateTime, 'yyyyMMdd')) as the FORMAT() function returns a NVARCHAR.

And I found this site which was very helpful http://aws-signature.com.s3-website-us-west-2.amazonaws.com/

Until Github sorts things out, you can download the models from their mirrors on the HuggingFace Hub and install them with pip, though you can't do this through the spacy download command unfortunately.

AWS GetSignedUrl generates wrong url with us-east-1 region by default
