viper supports Yaml, Json, TOML, HCL and other formats, and is very convenient to read.
There are cases on the viper official website:/spf13/viper
go get /spf13/viper
Create a file
database: driver: mysql host: 127.0.0.1 port: 3306 username: blog dbname: blog password: 123456
Create a configuration file for initializing
func InitConfig() {
path, err := ()
if err != nil {
panic(err)
}
(path + "/config/dev")
("config")
("yaml")
if err := (); err != nil {
panic(err)
}
}
Simple use:
username := ("")
password := ("")
host := ("")
port := ("")
dbname := ("")
dsn := ("%s:%s@tcp(%s:%d)/%s?charset=utf8&parseTime=True&loc=Local",username,password,host, port, dbname)
GormPool, err = ("mysql", dsn)
The above is all the content of this article. I hope it will be helpful to everyone's study and I hope everyone will support me more.
