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代码给了我下面的错误：
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:Python32libgzip.py", line 312, in write
self.crc = zlib.crc32(data, self.crc) & 0xffffffff
TypeError: 'str' does not support the buffer interface
如果您使用Python3x，那么string与Python 2.x的类型不同，您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'))
也不要使用变量名称，如string或file而这些名称是模块或函数的名称。

是的，非ASCII文本也被压缩/解压缩。 我使用UTF-8编码的波兰语字母：
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)
这个问题有一个更简单的解决方案。
你只需要添加一个t到模式，所以它变成wt 。 这会导致Python将文件作为文本文件打开而不是二进制文件。 那么一切都会正常工作。
完整的程序变成这样：
plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wt") as outfile:
outfile.write(plaintext)
你不能将一个Python 3'字符串'序列化为字节，而不需要向某些编码进行明确的转换。
outfile.write(plaintext.encode('utf-8'))
可能是你想要的。 这也适用于Python 2.x和3.x.
