DB writer

It sends data to a database. If database is unavailable, after 2 tries it will write into files in configurated directory. When the connection is back, it will resend data to DB in same query orders. Data table must contains field_server_id, to support multiinstanced daemons

Example

db,_  := gorm.Open("mysql", fmt.Sprintf("%s:%s@tcp(%s:%s)/%s?charset=%s&parseTime=True",
         	//Mysql.User,
         	//Mysql.Password,
         	//Mysql.Host,
         	//Mysql.Port,
         	//Table.Name,
         	"utf-8"))
         		
writer := dbwriter.New(dbwriter.WriteConfig{
	Db:                db,
	Log:               logrus.New(),
	FilePath:          mainConfig.DataWriter.FilePath,
	ServerId:          mainConfig.ServerId,
	TickTimeMs:        500, // it will send aggregated data to db every half second
	MaxConnectTimeSec: 2*60, // time, which for mysql connection is alive
})
//than 
data := struct {
    id      int       `gorm:column:id`
    name    string    `gorm:column:name`
    created time.Time `gorm:column:created`
}{1, "Name", time.Now()}
writer.Append(data)

HTTP Response

This package allows creating server response. We can choose from HTML, Json (if we need to set body nonstring type) or JSONMessage (if the body is a string) response types.
