Data URI manipulation made easy.
This isn't very robust, and will reject a number of valid data URIs. However, it meets the most useful case: a mimetype, a charset, and the base64 flag.
$ pip install python-datauri
>>> from datauri import DataURI >>> uri = DataURI('data:text/plain;charset=utf-8;base64,VGhlIHF1aWNrIGJyb3duIGZveCBqdW1wZWQgb3ZlciB0aGUgbGF6eSBkb2cu') >>> uri.mimetype 'text/plain' >>> uri.charset 'utf-8' >>> uri.is_base64 True >>> uri.data b'The quick brown fox jumped over the lazy dog.'
Note that DataURI.data will always return bytes.
Use DataURI.text to get a string.
>>> from datauri import DataURI >>> made = DataURI.make('text/plain', charset='us-ascii', base64=True, data='This is a message.') >>> made DataURI('data:text/plain;charset=us-ascii;base64,VGhpcyBpcyBhIG1lc3NhZ2Uu') >>> made.data b'This is a message.'
This is really just a convenience method.
>>> from datauri import DataURI >>> png_uri = DataURI.from_file('somefile.png') >>> png_uri.mimetype 'image/png' >>> png_uri.data b'\x89PNG\r\n...'
DataURI is a subclass of str, so you can just use str() to print it out:
>>> from datauri import DataURI >>> png_uri = DataURI.from_file('somefile.png') >>> str(png_uri) 'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAASABIA...'
You can use DataURI as a type for Pydantic:
from datauri import DataURI from pydantic import BaseModel class ProfilePicture(BaseModel): image_data: DataURI
