类型错误:'str' 不支持缓冲区接口 [英] TypeError: 'str' does not support the buffer interface

问题描述

plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wb") as outfile:
    outfile.write(plaintext) 

上面的python代码给了我以下错误:

The above python code is giving me following error:

Traceback (most recent call last):
  File "C:/Users/Ankur Gupta/Desktop/Python_works/gzip_work1.py", line 33, in <module>
    compress_string()
  File "C:/Users/Ankur Gupta/Desktop/Python_works/gzip_work1.py", line 15, in compress_string
    outfile.write(plaintext)
  File "C:Python32libgzip.py", line 312, in write
    self.crc = zlib.crc32(data, self.crc) & 0xffffffff
TypeError: 'str' does not support the buffer interface

推荐答案

如果您使用 Python3x，则 string 与 Python 2.x 的类型不同，您必须将其强制转换为字节(编码它).

If you use Python3x then string is not the same type as for Python 2.x, you must cast it to bytes (encode it).

plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wb") as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))

也不要使用像string或file这样的变量名，而这些都是模块或函数的名字.

Also do not use variable names like string or file while those are names of module or function.

是的，非 ASCII 文本也会被压缩/解压缩.我使用带有 UTF-8 编码的波兰语字母:

Yes, non-ASCII text is also compressed/decompressed. I use Polish letters with UTF-8 encoding:

plaintext = 'Polish text: ąćęłńóśźżĄĆĘŁŃÓŚŹŻ'
filename = 'foo.gz'
with gzip.open(filename, 'wb') as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))
with gzip.open(filename, 'r') as infile:
    outfile_content = infile.read().decode('UTF-8')
print(outfile_content)
