textfile = open(filename , 'w')
textfile.write(file.decode('base64')+binme+close)

但是当我尝试运行它时出现此错误：

Traceback (most recent call last):
  File "<string>", line 420, in run_nodebug
  File "<module1>", line 32, in <module>
TypeError: 'str' does not support the buffer interface

请问有什么问题？

Answer 1

试试这样：

textfile = open(filename , 'w')
textfile.write(bytes(file.decode('base64')+binme+close, 'UTF-8'))

或者像这样：

textfile = open(filename , 'wt') # note the 'wt' for write text
textfile.write(file.decode('base64')+binme+close)

最小的可验证示例以易于被其他人运行的方式演示故障点处的代码。由于您有版本问题，我添加了版本号的额外打印。

import sys
import binascii
print(sys.version_info)
url='http://example.com/nowhere'
binme=binascii.b2a_hex(url)

使用python 2和3运行

~/tmp $ python2 b.py
sys.version_info(major=2, minor=7, micro=6, releaselevel='final', serial=0)

~/tmp $ python3 b.py
sys.version_info(major=3, minor=4, micro=3, releaselevel='final', serial=0)
Traceback (most recent call last):
  File "b.py", line 5, in <module>
    binme=binascii.b2a_hex(url)
TypeError: 'str' does not support the buffer interface

如果您希望脚本在错误的版本上提前失败，请将其添加到导入

import sys
assert sys.version_info[0] == 3, "Must run on python 3"

TypeError traceback，python 2.7
