I am trying to convert a base64 string into a video file for use in a gem.
How do you take the base string and reformat it to what it was before it came through http.
Use Base64.decode and write directly the results to a file.

i read this post convert image to base64 with flutter but this is about converting image file to base64. How to convert online url to base64.
Right now i can think of one solution that is to store image in path and get that file path and convert it. thats how this post showing.
is there any other sort way to convert online image uri to base64?
Well to convert the image you need the image data otherwise there's nothing to convert. So the step for the most effecient would be.
Perform get request to the image url
Read all the bytes from the response body
Convert to base64
Save the base 64 string locally or use how you please.
You don't have to save it. Just keep in mind if the user closes the app or it stops at any point during this process you'll have to start it from the beginning because you're not saving the image to disk.
I'm currently working on a ruby on rails project. In the project I have a form with a input file type (An image) and I need to convert the image to base64 (The project connects to an external api, so the image needs to be in base64)
So far I have tried to do this Base64.encode64(target_params[:image].read)
but I get an empty string as result.
Just solve it using this code:
file =
target_params[:image].tempfile.open.read.force_encoding(Encoding::UTF_8)
Base64.encode64(file)
I have parameters FirstName,LastName,Email & image ,Which need to send in the form of base64.I need appropriate code for it.
Base64 is used to convert binary data into text.
In your situation only Image needs to be encoded in that format, the rest should be text.
Convert UIImage to Base64 string in Objective-C and Swift
How, in Ada, do I decode a string coming from the MS Windows terminal, then encode it in UTF-8?
Try looking in package Ada.Strings.UTF_Encoding.Conversions for UTF-handling.
As for retrieving text from the command-line you can use Ada.Command_Line, though there are also files/streams that you can use to get the standard input.
My method is supposed to accept base64 and turn it into a file. In grails, I am aware that there is Base64.decodeToFile(stringInBase64, fileName) but, what I'm given is just the base64, and no fileName/extension. Is there a way for me to transform the base64 string into a file without knowing the fileName? Something like, Base64.decodeToFile(stringInBase64)? My method should accept, png and ico extensions. :\
String.decodeBase64() will return a byte[]. You can append it to a File.
