Question

我有这段代码：

log.py

from .color import Color
import logging

class Log:
    logging.basicConfig(format='%(asctime)s,%(msecs)d %(levelname)-8s [%(filename)s:%(lineno)d] %(message)s',
                        datefmt='%d-%m-%Y:%H:%M:%S',
                        level=logging.INFO)
    logger = logging.getLogger('anywordcanbethis')

    @classmethod
    def warning(self, msg):
        Log.logger.warning(Color.fg.yellow + msg + Color.reset)

    @classmethod
    def error(self, msg):
        Log.logger.error(Color.fg.red + msg + Color.reset)

    @classmethod
    def debug(self, msg):
        Log.logger.info(Color.fg.pink + msg + Color.reset)

正如您所看到的，这样做的目的是在此类中设置日志记录选项，以便我的其他项目可以轻松地以我想要的方式使用logger：

import Log

Log.warning("BLAHBLAH") ->
31-05-2018:18:06:45,313 WARNING  [log.py:12] "BLAHBLAH" (yellow)
Log.error("BLAHBLAH") ->
31-05-2018:18:13:43,481 ERROR    [log.py:16] "BLAHBLAH" (red)

问题是，打印的行号始终是log.py:12＆lt; - 就像这样，我不想要。我想查看一个名为Log.warning，Log.error ...的文件，它可能位于更高级别的堆栈中。

我应该尝试记录哪些选项？

谢谢

您可以尝试使用docs中的Finds the caller’s source filename and line number. Returns the filename, line number and function name as a 3-element tuple. Changed in version 2.4: The function name was added. In earlier versions, the filename and line number were returned as a 2-element tuple.：

Logger.findCaller（）
findCaller

为了感兴趣，这里是def findCaller(self): """ Find the stack frame of the caller so that we can note the source file name and line number. """ rv = (None, None) frame = inspect.currentframe().f_back while frame: sfn = inspect.getsourcefile(frame) if sfn: sfn = os.path.normcase(sfn) if sfn != _srcfile: #print frame.f_code.co_code lineno = inspect.getlineno(frame) rv = (sfn, lineno) break frame = frame.f_back return rv方法（我注意到它返回一个2元素元组，因此它来自＆lt; 2.4）：

def findCaller(self, stack_info=False):
    """
    Find the stack frame of the caller so that we can note the source
    file name, line number and function name.
    """
    f = currentframe()
    #On some versions of IronPython, currentframe() returns None if
    #IronPython isn't run with -X:Frames.
    if f is not None:
        f = f.f_back
    rv = "(unknown file)", 0, "(unknown function)", None
    while hasattr(f, "f_code"):
        co = f.f_code
        filename = os.path.normcase(co.co_filename)
        if filename == _srcfile:
            f = f.f_back
            continue
        sinfo = None
        if stack_info:
            sio = io.StringIO()
            sio.write('Stack (most recent call last):\n')
            traceback.print_stack(f, file=sio)
            sinfo = sio.getvalue()
            if sinfo[-1] == '\n':
                sinfo = sinfo[:-1]
            sio.close()
        rv = (co.co_filename, f.f_lineno, co.co_name, sinfo)
        break
    return rv

我找到了最新版本：

public interface SOService {

@GET("stuff/getall")
Call<SOAnswersResponse> getAnswers();
}

如何获取以前直接调用登录的源代码行号？
