【问题描述】:
我需要能够使用文件描述符打开压缩后的 CSV 文件。当我执行以下操作时(这是仍然触发错误的简化代码):
file_path = r"E39O6KS6J8MIZW.00.0f6db4e5.gz"
fd = os.open(file_path, os.O_RDONLY, os.O_BINARY)
# ...
file_object = gzip.GzipFile(fileobj=io.FileIO(fd, mode='rb'))
reader = csv.reader(io.BufferedReader(file_object))
for row in reader:
print row
我收到一个 CRC 校验错误:
Traceback (most recent call last):
File "./log_processing_scripts/dev.py", line 40, in <module>
post()
File "./log_processing_scripts/dev.py", line 36, in post
for row in reader:
File "C:\Python27\lib\gzip.py", line 252, in read
self._read(readsize)
File "C:\Python27\lib\gzip.py", line 299, in _read
self._read_eof()
File "C:\Python27\lib\gzip.py", line 338, in _read_eof
hex(self.crc)))
IOError: CRC check failed 0x4b77635f != 0xbe13716L
文件没有(!)损坏,我可以使用 gzip.open(file_path)处理它。
我错过了什么?
