Base64编码解码

Python

import json
import base64
data = {'success': 0, 'message': 'ok', 'data': [i for i in range(10)]}
enc_data = base64.b64encode(json.dumps(data).encode())
# b'eyJzdWNjZXNzIjogMCwgIm1lc3NhZ2UiOiAib2siLCAiZGF0YSI6IFswLCAxLCAyLCAzLCA0LCA1LCA2LCA3LCA4LCA5XX0='
base64.b64decode(enc_data)
# b'{"success": 0, "message": "ok", "data": [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]}'
