Python3壓縮記錄器模塊在飛行中登錄

Question

我無法找到一種方法來壓縮我用logger模塊編寫的日誌。

例如：

import logging 
import gzip 

logger = logging.getLogger('') 
z_file = gzip.open('out.log.gz', mode='wb') 
logger.addHandler(logging.StreamHandler(z_file)) 
logger.warning("test".encode("UTF-8")) 

兩個codecs.open和gzip.open給我

--- Logging error --- 
Traceback (most recent call last): 
    File "/usr/lib/python3.4/logging/__init__.py", line 966, in emit 
    stream.write(msg) 
    File "/usr/lib/python3.4/gzip.py", line 343, in write 
    self.crc = zlib.crc32(data, self.crc) & 0xffffffff 
TypeError: 'str' does not support the buffer interface 

當我試圖用自己的處理程序。我究竟做錯了什麼？

指定encoding到gzip.open。您應該使用顯式文本模式（wt）來指定編碼。只需將一個字符串傳遞給日誌記錄方法即可。

import logging 
import gzip 

logger = logging.getLogger('') 
z_file = gzip.open('out.log.gz', mode='wt', encoding='utf-8') 
logger.addHandler(logging.StreamHandler(z_file)) 
logger.warning("test")
