# Log4p日志库
|
||||
|
||||
## 描述
|
||||
|
||||
这是一个可以支持异步记录日志,发送到HTTP,websocket服务器,同时配置简单,它还实现了识别代码异步和同步的环境
|
||||
以支持不同环境下的日志记录,当然了,理论上,这个日志如果2个模式都启用(websocket,http),那么会分别的往2个地方发送日志
|
||||
|
||||
### 示例用法
|
||||
|
||||
```python
|
||||
#from core import *
|
||||
from Log4p import LogManager
|
||||
|
||||
logger = LogManager().GetLogger(
|
||||
log_name='example',
|
||||
out_to_console=True,
|
||||
web_log_mode=True,
|
||||
WSpost_url='ws://localhost:8765',
|
||||
HTTPpost_url='http://localhost:8765',
|
||||
http_mode = True
|
||||
custom_fomatter='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
|
||||
)
|
||||
|
||||
logger.info('这是一个成功信息')
|
||||
logger.debug('这是一个调试信息')
|
||||
logger.critical('这是一个严重错误信息')
|
||||
logger.error('这是一个错误信息')
|
||||
logger.warning('这是一个警告信息')
|
||||
```
|
||||
|
||||
### 参数介绍
|
||||
|
||||
- `log_name`: 指定日志记录器的名称
|
||||
- `out_to_console`: 是否输出到控制台,默认true
|
||||
- `web_log_mode`:是否启用websocket日志输出模式,默认false
|
||||
- `WSpost_url`: 如果启用websocket模式,则传入post_url,否则不管,默认None
|
||||
- `HTTPpost_url`: 如果启用http模式,则传入post_url,否则不管,默认None
|
||||
- `http_mode`: 是否启用http日志输出模式,默认false
|
||||
|
||||
## 更新日志
|
||||
|
||||
# 2024/2/20 1:01
|
||||
|
||||
更新了自定义格式功能,修复了少量bug
|
||||
|
||||
## 添加参数
|
||||
|
||||
- `custom_formatter`: 自定义格式化函数,默认None
