Jinja2：将十六进制转换为Base64

Question

Is this possible?

Say I have a hex value 32ABE23 , is there a filter to show it as Base64? Well I saw that there is | b64encode filter.

I trried following with no success

{{ 32ABE23 | string() | b64encode }}

I get

TemplateAssertionError: no filter named 'b64encode'

Answer 1

You can define your own filters in Jinja2:

import base64
def b64encode(s):
    return base64.b64encode(s)

jinja2_environment.filters['b64encode'] = b64encode

Of course this can be simplified as:

import base64
jinja2_environment.filters['b64encode'] = base64.b64encode
