Python-TypeError：“ str”不支持缓冲区接口

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：

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:\Python32\lib\gzip.py", line 312, in write
    self.crc = zlib.crc32(data, self.crc) & 0xffffffff
TypeError: 'str' does not support the buffer interface

回答：

如果使用Python3x，则string与Python 2.x的类型不同，则必须将其转换为字节（对其进行编码）。

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或那样的变量file名作为模块或函数的名称。

是的，非ASCII文本也会被压缩/解压缩。我使用UTF-8编码的波兰字母：

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)
