Sanic框架之日誌記錄

前言

Sanic沒有像Flask那麼優秀的集成了logging。可是項目中日誌功能又必不可少。因此就來學習下

首先是官方的一個例子

from sanic import Sanic
from sanic.config import LOGGING

# The default logging handlers are ['accessStream', 'errorStream']
# but we change it to use other handlers here for demo purpose
LOGGING['loggers']['network']['handlers'] = [
    'accessSysLog', 'errorSysLog']

app = Sanic('test')

@app.route('/')
async def test(request):
    return response.text('Hello World!')

if __name__ == "__main__":
  app.run(log_config=LOGGING)
```
### 能夠看出，sanic有關於對logging的配置。可是若是像Flask中直接使用的話，還須要改造一下。
```python
from sanic.response import json
from sanic import Sanic
from sanic.config import LOGGING
import logging

class sanic(Sanic):

    def __init__(self,*args,**kwargs):
        super(sanic,self).__init__(*args,**kwargs)

        self.web_app = Sanic(__name__)
        self.web_app.config.LOGO = None
        self.web_app.log_config = LOGGING
        self.web_app.logger = self.logger()

    def logger(self):
        return logging.getLogger('sanic')

    def create_app(self):
        return self.web_app


@app.route('/')
async def get(request):
    current_app = request.app
    current_app.logger.debug('111111111111111111111111111111111111111111111111111111111111111111')
    return json({1: 2})

if __name__ == '__main__':
    app = sanic().create_app()
    app.run(debug=True)
```
#### 繼承一個sanic的類，而後給他一個logging的屬性。這樣就能夠像FLask同樣的使用了
