如何将任何类型的文件编码为base64字符串,然后使用Lazarus/Delphi将其解码为文件？

import base64

file_content = "Hello, world!"
encoded_string = base64.b64encode(file_content.encode("utf-8"))

import base64

encoded_string = "SGVsbG8sIHdvcmxkIQ=="
decoded_file = base64.b64decode(encoded_string).decode("utf-8")

decoded_file_path = "decoded.txt"
with open(decoded_file_path, "w") as f:
    f.write(decoded_file)
