What's the correct way to send a file to a function?

Hello everyone! 😊

I have a hard time figuring out the right way to send a file to an Appwrite function.

Lets say I have an image that I'd like to pass to a function, alongside a description of the file. Should I just pass it like this?

Dart:
``Uint8List pngBytes = await fetchPngBytes('');

final execution = await appWriteClientController.function.createExecution(
functionId: 'upload-file,
body: jsonEncode({
'description': 'A test file',
'file': pngBytes,
}));``

I also notice people encode the file to base64 first and pass that to the function. Is that a better way to pass the file?

Another thing I read is that 'Accept: multipart/form-data' should be passed to createExecution when a file is passed to a function. Is this correct?

The function side is also a bit unclear to me:

node.js:
const file = req.bodyBinary; if (!file) { return res.json({ success: false, message: 'No file received' }); } else { return res.json({ success: true, }); }

Is this the right way to retrieve the file in my function? 🤔

Hey, check this post with the same question: https://discord.com/channels/564160730845151244/1157683118782816328

Thanks. That question was asked a long time before binary support was added to functions in Appwrite V1.6. Is the code shown there still a best practice, or is there a better way to do it now?

I mean, it's now possible to pass a file through createExecution, right?

I'm sorry you're right, there is a better documentation with a binary file feature: https://appwrite.io/blog/post/introducing-functions-ecosystem#binary-executions

Thanks. 👍🏻👍🏻

I investigated further and I think it's not possible to upload a file through createExecution as binary, because it only takes a string as body parameter? 🤔
