Logging To Specific Error Log File In Scrapy

I am running a log of scrapy by doing this: from scrapy import log class MySpider(BaseSpider): name = 'myspider' def __init__(self, name=None, **kwargs): LOG_FILE =

Solution 1:

Just let logging do the job. Try to use PythonLoggingObserver instead of DefaultObserver:

• configure two loggers (one for INFO and one for ERROR messages) directly in python, or via fileconfig, or via dictconfig (see docs)

• start it in spider's __init__:

  def __init__(self, name=None, **kwargs):
      # TODO: configure logging: e.g. logging.config.fileConfig("logging.conf")
      observer = log.PythonLoggingObserver()
      observer.start()
  

Let me know if you need help with configuring loggers.

EDIT:

Another option is to start two file log observers in __init__.py:

from scrapy.log import ScrapyFileLogObserver
from scrapy import log


classMySpider(BaseSpider):
    name = "myspider"def__init__(self, name=None, **kwargs):
        ScrapyFileLogObserver(open("spider.log", 'w'), level=logging.INFO).start()
        ScrapyFileLogObserver(open("spider_error.log", 'w'), level=logging.ERROR).start()

        super(MySpider, self).__init__(name, **kwargs)

    ...
