以下代码在 python 2 机器上成功运行:
base64_str = base64.encodestring('%s:%s' % (username,password)).replace('\n', '')
我正在尝试将它移植到 Python 3，但是当我这样做时遇到以下错误:
>>> a = base64.encodestring('{0}:{1}'.format(username,password)).replace('\n','')
Traceback (most recent call last):
File "/auto/pysw/cel55/python/3.4.1/lib/python3.4/base64.py", line 519, in _input_type_check
m = memoryview(s)
TypeError: memoryview: str object does not have the buffer interface
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/auto/pysw/cel55/python/3.4.1/lib/python3.4/base64.py", line 548, in encodestring
return encodebytes(s)
File "/auto/pysw/cel55/python/3.4.1/lib/python3.4/base64.py", line 536, in encodebytes

raise TypeError(msg) from err
TypeError: expected bytes-like object, not str
我尝试搜索 encodestring 用法的示例，但找不到合适的文档。我错过了一些明显的东西吗？我在 RHEL 2.6.18-371.11.1.el5 上运行这个
最佳答案
您可以encode() 字符串(将其转换为字节字符串)，然后再将其传递给base64.encodestring。示例 -
base64_str = base64.encodestring(('%s:%s' % (username,password)).encode()).decode().strip()
