## logs
logs is a Go logs manager. It can use many logs adapters. The repo is inspired by `database/sql` .
## How to install?
go get github.com/astaxie/beego/logs
## What adapters are supported?
As of now this logs support console, file,smtp and conn.
## How to use it?
First you must import it
```golang
import (
"github.com/astaxie/beego/logs"
)
```
Then init a Log (example with console adapter)
```golang
log := logs.NewLogger(10000)
log.SetLogger("console", "")
```
> the first params stand for how many channel
Use it like this:
```golang
log.Trace("trace")
log.Info("info")
log.Warn("warning")
log.Debug("debug")
log.Critical("critical")
```
## File adapter
Configure file adapter like this:
```golang
log := NewLogger(10000)
log.SetLogger("file", `{"filename":"test.log"}`)
```
## Conn adapter
Configure like this:
```golang
log := NewLogger(1000)
log.SetLogger("conn", `{"net":"tcp","addr":":7020"}`)
log.Info("info")
```
## Smtp adapter
Configure like this:
```golang
log := NewLogger(10000)
log.SetLogger("smtp", `{"username":"beegotest@gmail.com","password":"xxxxxxxx","host":"smtp.gmail.com:587","sendTos":["xiemengjun@gmail.com"]}`)
log.Critical("sendmail critical")
time.Sleep(time.Second * 30)
```
