# 自定义日志
|
|||
|
|
|||
|
NoneBot 使用 [Loguru](https://loguru.readthedocs.io/) 进行日志记录,并提供了一些内置的格式和过滤器等。
|
|||
|
|
|||
|
## 默认日志
|
|||
|
|
|||
|
NoneBot 启动时会添加一个默认的日志 handler。此 handler 将会将日志输出到 **stdout**,并且根据配置的日志级别进行过滤。
|
|||
|
|
|||
|
[默认格式](../api/log.md#default_format)):
|
|||
|
|
|||
|
```python
|
|||
|
default_format: str = (
|
|||
|
"<g>{time:MM-DD HH:mm:ss}</g> "
|
|||
|
"[<lvl>{level}</lvl>] "
|
|||
|
"<c><u>{name}</u></c> | "
|
|||
|
"{message}"
|
|||
|
)
|
|||
|
|
|||
|
from nonebot.log import default_format
|
|||
|
```
|
|||
|
|
|||
|
[默认过滤器](../api/log.md#default_filter):
|
|||
|
|
|||
|
```python
|
|||
|
from nonebot.log import default_filter
|
|||
|
```
|
|||
|
|
|||
|
## 转移 logging 日志
|
|||
|
|
|||
|
NoneBot 提供了一个 logging handler 用于将日志输出转移至 loguru 处理。将 logging 的默认 handler 替换为 `LoguruHandler` 即可。
|
|||
|
|
|||
|
```python
|
|||
|
from nonebot.log import LoguruHandler
|
|||
|
```
|
|||
|
|
|||
|
## 自定义日志记录
|
|||
|
|
|||
|
如果需要移除 NoneBot 的默认日志 handler,可以在 `nonebot.init` 之前进行如下操作:
|
|||
|
|
|||
|
```python
|
|||
|
from nonebot.log import logger, logger_id
|
|||
|
|
|||
|
logger.remove(logger_id)
|
|||
|
```
|
|||
|
|
|||
|
如果需要添加自定义的日志 handler,可以在 `nonebot.init` 之前添加 handler,参考 [loguru 文档](https://loguru.readthedocs.io/)。
|
|||
|
|
|||
|
示例:
|
|||
|
|
|||
|
```python
|
|||
|
from nonebot.log import logger, default_format
|
|||
|
|
|||
|
logger.add("error.log", level="ERROR", format=default_format, rotation="1 week")
|
|||
|
```
