I need to convert image (or any file) to base64 string. I use different ways, but result is always byte, not string. Example:
import base64
file = open('test.png', 'rb')
file_content = file.read()
base64_one = base64.encodestring(file_content)
base64_two = base64.b64encode(file_content)
print(type(base64_one))
print(type(base64_two))
Returned
<class 'bytes'>
<class 'bytes'>
How do I get a string, not byte? Python 3.4.2.
Base64 is an ascii encoding so you can just decode with ascii
>>> import base64
>>> example = b'\x01'*10
>>> example
b'\x01\x01\x01\x01\x01\x01\x01\x01\x01\x01'
>>> result = base64.b64encode(example).decode('ascii')
>>> print(repr(result))
'AQEBAQEBAQEBAQ=='
I need to write base64 text in file ...
So then stop worrying about strings and just do that instead.
with open('output.b64', 'wb'):
write(base64_one)
The following code worked for me:
import base64
file_text = open(file, 'rb')
file_read = file_text.read()
file_encode = base64.encodebytes(file_read)
I initially tried base64.encodestring() but that function has been deprecated as per this issue.
base64.encodebytes will insert \n characters "after every 76 bytes of output" per the docs.
