Use of YAML configuration files in the Go language

In this article, Yaml uses a third-party open source gopkg.in/yaml.v2 on GitHub.
How to use it specifically.
First step: Download

Go get gopkg.in/yaml.v2

Step two: Create a yaml file, such as Conf.yaml

host:localhost:3306
user:root
pwd:123456
dbname:test

It is important to note that there are spaces behind the colon in user:root, for example

Step three: Create a new go file, such as Main.go

Package main

Import (
    "Io/ioutil" "Gopkg.in/yaml.v2" "
    fmt"
)

func main () {
   var c conf
   conf:=c.getconf ()
   FMT. Println (CONF. Host)
}

//profile variables
type conf struct {
    host string ' Yaml: "Host" '
    User string ' Yaml: " User "'
    pwd string ' yaml:" pwd "'
    Dbname string ' yaml:" Dbname "'
}
func (c *conf) getconf () *conf {
    Yamlfile, err: = Ioutil. ReadFile ("Conf.yaml")
    if err! = Nil {
        FMT. Println (Err. Error ())
    }
    err = Yaml. Unmarshal (Yamlfile, c)
    if err! = Nil {
        FMT. Println (Err. Error ())
    }
    return c
}

Run Main.go, you can print out the user's value in the configuration file root
