翻看了一下 loguru 的源代码
loguru 有很恶心的 pyi 文件来影响咱们看源代码，倡议删除 pyi 后再看。python 删除 pyi 文件
能够应用 logger.bind,然而 logger.bind 会返回一个新的 logger，当前都要应用这个新的 logger 才行
ll=logger.bind(project_name="ideaboom")参考文章:How to use Loguru defaults + and extra information?
loguru 貌似没有提供原地批改的形式，只能通过这种 logger.bind 生成一个新的 logger 的形式
残缺代码：
from loguru._recattrs import RecordExceptionfrom loguru._handler import Handlerfrom loguru import loggerimport sysimport jsonlogger.remove()logger.add(sys.stdout, serialize='json')ll=logger.bind(project_name="ideaboom")ll.debug('哈哈哈')从上面的运行后果，能够看到，extra 中曾经带上 project_name 了
