基于python脚本的django自定义命令

Question

我正在尝试为 django 创建一个可以运行的自定义命令python manage.py cert_transparency，我已经快完成了，但遇到了一些麻烦。这个的目的是在后台创建一个 24/7 运行的命令，我只是在 docker 容器中运行它。我收到此错误消息certificate_update: 0cert [00:00, ?cert/s]Traceback (most recent call last):  File "manage.py", line 15, in <module>    execute_from_command_line(sys.argv)  File "/usr/local/lib/python3.7/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line    utility.execute()  File "/usr/local/lib/python3.7/site-packages/django/core/management/__init__.py", line 395, in execute    self.fetch_command(subcommand).run_from_argv(self.argv)  File "/usr/local/lib/python3.7/site-packages/django/core/management/base.py", line 330, in run_from_argv    self.execute(*args, **cmd_options)  File "/usr/local/lib/python3.7/site-packages/django/core/management/base.py", line 371, in execute    output = self.handle(*args, **options)  File "/src/scraper/management/commands/cert_transparency.py", line 184, in handle    certstream.listen_for_events(callback, url=certstream_url)NameError: name 'callback' is not defined基本上我想做的只是将此脚本作为 django 中的自定义管理命令导入。

您定义了该.callback(…)方法两次，所以我认为您应该删除其中之一。.callback(…)您可以使用以下方法传递对该方法的引用self.callback：

def handle(self, *args, **options):
    # …
    certstream.listen_for_events(self.callback, url=certstream_url)
