When you request of POST, you want to log the request body parameter like JSON.
The log format function is very useful.
Please use log format function instead “tokens” property for use express's request or response.
```javascript
app.use(log4js.connectLogger(logger, {
level: 'info',
format: (req, res, format) => format(`:remote-addr :method :url ${JSON.stringify(req.body)}`)
}));

* http responses 3xx, level = WARN
