I am working in building a real estate application
using spring boot java and the application in the aws server and images uploading in s3 bucket
what i want is that when the user add a propery if the the user close the app
the uploading task continue in the background and notify when complete
I found a resumeUpload method looks like just you want here.
Also an upload example in the aws s3 document.
Wish this help.
AWS Amplify can now be used with react native and expo SDK25 (Create React Native App) without ejecting first. This is great for those looking to stay within the AWS ecosystem and use Cognito User Pools.
But I couldn't find a way to use AWS Amplify to let the user make updates to their data (e.g. fix a name spelling, change phone number, etc.). Has anyone else been able to do this and if so how?
mutable user attributes are planned to be pushed in our next release this coming Monday 1/29/2018
I'm using AWS SDK for Ruby to upload large files from users to s3.
The server is a sinatra app with a POST /images endpoint accepting multipart/form-data. I'm experiencing a noticeable delay with user uploads. This is to be expected, because it's making a request to s3 synchronously. I wanted to move this to a background job using something like Sidekiq, but I'm not sure I like that solution.
I read online that some people are promoting direct uploads to s3 on the client side. Some even called this a "best practice." I'm hesitant to do this for several reasons:
My client side code would be heavily tied down to my cloud provider. I love AWS (great experiences), but I like to remain somewhat cloud-agnostic. I don't want my mobile and web apps to have to know the details of my AWS setup. If I choose to move away from s3 at a later date (unlikely but plausible), I would want this to be a seamless transition. Obviously, this works ok for a web app, because I can always redeploy quickly. However, I have to worry about mobile. Users may not update, and everything will become a lot more complicated if some users are uploading to s3 and some are uploading to another service.
Business logic regarding determining which bucket and region to use would need to either exist on the client side or I'd need to expose an endpoint for determining which bucket and region to use for each user. Then, I'd have to make a request to my server to figure out the parameters before I can begin uploading to s3. I want to be able to change buckets or re-route users to alternative regions and so I'm not a fan of this tight coupling or the additional request.
Security is a huge concern. When files are uploaded and processed through my server, I can utilize AWS IAM to properly ensure that these files are only coming from my server. I believe that I have to grant an "all-write" privilege to users which is problematic. If I use AWS IAM credentials in JavaScript, I do not see how you can ensure that users do not get unlimited write access to my bucket. All client side javascript, can be read by a user. In addition, I'm unaware of how to process validations. On my server, I can scan the files and determine whether or not to upload to s3. If I upload directly from the client, I would have to move this processing into lambda functions. I'm ok with that, but there is a chance the object could be retrieved by users before the processing has occurred. Then, I'd have to build some sort of locking system to prevent access before processing.
So, the bottom line is I have no idea where to go from here. I've hacked around some solutions, but I'm not thrilled with any of them. I'd love to learn how other startups and enterprises are tackling this kind of problem. What would you recommend? How would you counter my argument? Forgive me if I'm missing something, I'm still relatively an AWS-newbie.
If you're worried about changing the post service I would suggest using an API and that way you can change the backed storage for your service. The mobile or web client would call the service and then your api would place the file where it needed to go. The api you have more control over and you could just created a signed s3 url to send to the client and let them still do the uploading.
An api, like in 1, solves this problem too, the client doesn't have to do all the work.
Use Simple Token Services and Temporary Security Credentials.
I agree with strongjz, you should use an API to upload your files from the server side.
Cloudinary provides an API for uploading images and videos to the cloud.
From what I know from my experience in using Cloudinary it is the right solution for you.
All your images, videos and required metadata are stored and managed by Cloudinary in Amazon S3 buckets owned by Cloudinary.
The default maximum file size limit for videos is 40MB. This can be customized for paid plans.
For example in Ruby:
Cloudinary::Uploader.upload("sample_spreadsheet.xls", :resource_type =>
:raw)
I was looking for a tutorial or stackoverflow thread but I couldn't find a best practice how I can do it.
I have an ios swift app and I want to send sms if a user create an add a record in Firebase, like sending an invitation to someone or doing something which could affect other user.
According to some post on the internet and on your blog I need a server side script which makes it safe and I don't have to store those information in my swift code. Like here: https://www.twilio.com/blog/2016/11/how-to-send-an-sms-from-ios-in-swift.html
Currently I don't have a server. Only thing that I have is a Firebase account.
What is a best practice regarding security? For instance shall I create a webserver on AWS or just a AWS S3 bucket would be enough and shall I store those credentials or php codes there?
I'm quite new in the these things and unfortunately I don't know whom shall I ask.
Can somebody help me?
I'm a Java backend engineer working on a feature that the frontend (SPA and Android) must send (large) files to S3. Since I have to manage with a lot of requests. Because of network overload reasons I'm avoiding to make a 'proxy' service where the frontend send me the file so that I can send it to S3 but I have some concern about the best way to keep my apps secure.
I looked for some solutions but I cannot find one that manages exactly what I want.
Amazon S3 upload with not showing secret key in frontend
This post has almost my answer but I don't have enough score to comment.
S3 upload directly in JavaScript
I read some documentation on AWS but I still have some questions and some requisites.
The solution may permit the client an authenticated user to send a file to s3 directly
It may make a GET call to get some token or something like that (without sending a lot of data)
It's to be secure (no secret key knowledge at the frontend)
Which solution may be good for me?
The backend may generate a signing key and send it to frontend making the request to AWS (http://docs.aws.amazon.com/general/latest/gr/signature-v4-examples.html)
I can use STS to generate a temporary credential for each upload.
Do you think these approach will work? Which one do you think is better? What are the trade offs? Is there other way to deal with this problem?
Best thing to do here is use the Cognito service to generate anonymous credentials in the app that allow an upload to S3. For Android you can use the SDK then to do multi-part uploads from the device to S3, which will speed up the process as well.
I couldn't find an exact Android example, but this is one for iOS and the terminology should transfer the same, just with the other SDK: iOSTransferManager .
You can also call Cognito directly from javascript, if you have a web based app: Cognito in JS example
Hope that helps!
