            How to get token from API with Python?

            ANSWER

            Answered 2021-Jun-12 at 17:16

            First note that a token must be obtained from the server ! A token is required to make some API calls due to security concerns. There are usually at least two types of tokens:

            • Access token: You use it to make API calls (as in the Authorization header above). But this token usually expires after a short period of time.
            • Refresh token: Use this token to refresh the access token after it has expired.

            You should use requests-oauthlib in addition with requests.
            https://pypi.org/project/requests-oauthlib/
            But first, read the available token acquisition workflows:
            https://requests-oauthlib.readthedocs.io/en/latest/oauth2_workflow.html#available-workflows
            and choose the right workflow that suits your purposes. (The most frequently used is Web App workflow)
            Then, implement the workflow in your code to obtain the token. Once a valid token is obtained you can use it to make various API calls.

            As a side note: be sure to refresh token if required.

            To update existing image you should use html.Img(...) instead of html.Div(..., children=[]) in app.layout, and update component_property='src' instead of component_property='children'

            Many tools can save image/file in file-like object created in memory with io.BytesIO()

            CloudFormation (CFN) is not going to take your chaklader.pem and create a pair key in AWS. You have to do it before hand yourself. And you can't use CFN for that as it is not supported, unless you will program such a logic yourself using custom resource.

            The easiest way is to create or import the key "manually" using AWS Console, SDK or CLI. Then you can reference its name in your template.

            Images storage performance react native (base64 vs uri path)
            Asked 2021-Jun-13 at 23:16

            I have an app to create reports with some data and images (min 1 img, max 6). This reports keeps saved on my app, until user sent it to API (which can be done at the same day that he registered a report, or a week later).

            But my question is: What's the proper way to store this images (I'm using Realm), is it saving the path (uri) or a base64 string? My current version keeps the base64 for this images (500 ~~ 800 kb img size), and then after my users send his reports to API, I deleted this base64 hash.

            I was developing a way to save the path to the image, and then I display it. But image-picker uri returned is temporary. So to do this, I need to copy this file to another place, then save the path. But doing it, I got (for kind of 2 or 3 days) 2x images stored on phone (using memory).

            So before I develop all this stuff, I was wondering, will it (copy image to another path then save path) be more performant that save base64 hash (to store at phone), or it shouldn't make much difference?

            ANSWER

            Answered 2021-Apr-26 at 17:49

            I try to avoid text only answers; including code is best practice but the question about storing images comes up frequently and it's not really covered in the documentation so I thought it should be addressed at a high level.

            Generally speaking, Realm is not a solution for storing blob type data - images, pdf's etc. There are a number of technical reasons for that but most importantly, an image can go well beyond the capacity of a Realm field. Additionally it can significantly impact performance (especially in a sync'ing use case)

            If this is a local only app, storing the images on disk in the device and keep a reference to where they are (their path) stored in Realm. That will enable the app to be fast and responsive with a minimal footprint.

            If this is a sync'd solution where you want to share images across devices or with other users, there are several cloud based solutions to accommodate image storage and then store a URL to the image in Realm.

            One option is part of the MongoDB family of products (which also includes MongoDB Realm) called GridFS. Another option is a solid product we've leveraged for years is called Firebase Cloud Storage.

            Now that I've made those statements, I'll backtrack just a bit and refer you to this article Realm Data and Partitioning Strategy Behind the WildAid O-FISH Mobile Apps which is a fantastic article about implementing Realm in a real-world use application and in particular how to deal with images.

            In that article, note they do store the images in Realm for a short time. However, one thing they left out of that (which was revealed in a forum post) is that the images are compressed to ensure they don't go above the Realm field size limit.

            I am not totally on board with general use of that technique but it works for that specific use case.

            One more note: the image sizes mentioned in the question are pretty small (500 ~~ 800 kb img size) and that's a tiny amount of data which would really not have an impact, so storing them in realm as a data object would work fine. The caveat to that is future expansion; if you decide to later store larger images, it would require a complete re-write of the code; so why not plan for that up front.

            CameraX Analysis / Camera onPreviewFrame

            In CameraX Analysis, setTargetResolution(new Size(2560, 800), but in Analyzer imageProxy.getImage.getWidth=1280 and getHeight=400, and YUVToByte(imageProxy.getImage).length()=768000。In Camera, parameter.setPreviewSize(2560, 800) then byte[].length in onPreviewFrame is 3072000(equales 768000*(2560/1280)*(800/400))。How can I make CameraX Analyzer imageProxy.getImage.getWidth and getHeight = 2560 and 800, and YUVToByte(ImageProxy.getImage).length()=3072000?

            Answered 2021-Jun-13 at 01:15

            With regards to the image analysis resolution, the documentation of ImageAnalysis.Builder.setTargetResolution() states that:

            The maximum available resolution that could be selected for an ImageAnalysis is limited to be under 1080p.

            So setting a size of 2560x800 won't work as you expect. In return CameraX seems to be selecting the maximum ImageAnalysis resolution that has the same aspect ratio you requested (2560/800 = 1280/400).
