一个应用可能希望把所有的log信息都发送到一个log文件中去,所有的error级别以上的log信息都发送到stdout,所有critical 的log信息通过email发送.这个场景里要求三个不同handler处理,每个handler负责把特定的log信息发送到特定的地方.
file_handler = logging.FileHandler('log.txt') file_handler.setLevel(logging.INFO) file_handler.setFormatter(formatter) Handler处理器类型常用的有三个,StreamHandler,FileHandler,NullHandler。StreamHandler:日志以数据流形式输出,即输出到stdoutFileHandler:日志输出到文件里头NullHandler:啥也不做 创建Handler之后,可...

Log to stdout With the logging.basicConfig() Function in Python The basicConfig() method in Python’s logging module serves as a convenient and quick way to set up a basic configuration for logging. This method allows developers to establish fundamental parameters, such as the logging level, out...
logging.basicConfig(level=logging.INFO,filename='logger.log')logging.info("info message") 所以这里的简易配置所指的就是root日志对象,随拿随用。每个logger都是单例对象所以配置过一遍之后程序内任何地方调用都可以。我们只需要调用basicConfig就可以对root日志对象进行简易的配置,事实上这种方式相当有效易用。它使得...
log.setLevel(logging.DEBUG) log.addHandler(logging.StreamHandler(sys.stdout))#默认sys.error log.info('print info level log to console') 2.输出日志到文件 1 2 3 4 5 6 7 8 importsys importlogging log = logging.getLogger(__name__)
# open our log file so = se = open("%s.log" % self.name, 'w', 0) # re-open stdout without buffering sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0) # redirect stdout and stderr to the log file opened above os.dup2(so.fileno(), sys.stdout.fileno()) ...
