import ftplib import urllib2 import os import logging logger = logging.getLogger('ftpuploader') hdlr = logging.FileHandler('ftplog.log') formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s') hdlr.setFormatter(formatter) logger.addHandler(hdlr) logger.setLevel(logging.INFO) FTPADDR = "some ftp address" def upload_to_ftp(con, filepath): try: f = open(filepath,'rb') # file to send con.storbinary('STOR '+ filepath, f) # Send the file f.close() # Close file and FTP logger.info('File successfully uploaded to '+ FTPADDR) except, e: logger.error('Failed to upload to ftp: '+ str(e))
這彷佛不起做用,出現語法錯誤,將全部類型的異常記錄到文件中的正確方法是什麼 python
python 3再也不支持該語法。請改用如下內容。 安全
try: do_something() except BaseException as e: logger.error('Failed to do something: ' + str(e))
將其更新爲更簡單的記錄器(適用於python 2和3)。 您不須要回溯模塊。 url
import logging logger = logging.Logger('catch_all') def catchEverythingInLog(): try: ... do something ... except Exception as e: logger.error(e, exc_info=True) ... exception handling ...
如今這是舊方法(儘管仍然有效): spa
import sys, traceback def catchEverything(): try: ... some operation(s) ... except: exc_type, exc_value, exc_traceback = sys.exc_info() ... exception handling ...
exc_value是錯誤消息。 code
您能夠使用logger.exception("msg")
來記錄帶有回溯的異常: orm
try: #your code except Exception as e: logger.exception('Failed: ' + str(e))
在某些狀況下,您能夠使用e.message或e.messages ..可是,並不是在全部狀況下都有效。 不管如何,使用str(e)更安全 get
try: ... except Exception as e: print(e.message)
您能夠嘗試明確指定BaseException類型。 可是,這隻會捕獲BaseException的派生類。 儘管這包括全部實現提供的異常,但也有可能引起任意舊式類。 io
try: do_something() except BaseException, e: logger.error('Failed to do something: ' + str(e))
