python - 'TypeError : 'str' does not support the buffer interface' - python 3. 4 从 2.7 转换

Question

我尝试从 python 2.7 转换为 3.4，并在尝试使用 b64encode 时出现以下错误:

from base64 import b64encode

username = 'manager'
password = 'test.manager'

headers = {"Authorization": " Basic " + b64encode(username + ":" + password), "Content-Type": "application/json"}

错误:

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "C:\python34\Lib\base64.py", line 62, in b64encode
    encoded = binascii.b2a_base64(s)[:-1]
**TypeError: 'str' does not support the buffer interface**

Answer 1

改用bytes对象:

username = b'manager'
password = b'test.manager'

headers = {"Authorization": b" Basic " + b64encode(username + b":" + password), "Content-Type": "application/json"}
