viper website with case: https: / / github com/spf13 / viper
go get github.com/spf13/viper
Create the config.yaml file
database:
driver: mysql
host: 127.0.0.1
port: 3306
username: blog
dbname: blog
password: 123456
Create an ES23en.go to initialize the configuration file
func InitConfig() {
path, err := os.Getwd()
if err != nil {
panic(err)
}
viper.AddConfigPath(path + "/config/dev")
viper.SetConfigName("config")
viper.SetConfigType("yaml")
if err := viper.ReadInConfig(); err != nil {
panic(err)
}
}
Simple use:
username := viper.GetString("database.username")
password := viper.GetString("database.password")
host := viper.GetString("database.host")
port := viper.GetInt("database.port")
dbname := viper.GetString("database.dbname")
dsn := fmt.Sprintf("%s:%s@tcp(%s:%d)/%s?charset=utf8&parseTime=True&loc=Local",username,password,host, port, dbname)
GormPool, err = gorm.Open("mysql", dsn)
