go - How to read a YAML file

Question

I have an issue with reading a YAML file. I think it's something in the file structure but I can't figure out what.

YAML file:

conf:
  hits:5
  time:5000000

code:

type conf struct {
    hits int64 `yaml:"hits"`
    time int64 `yaml:"time"`
}


func (c *conf) getConf() *conf {

    yamlFile, err := ioutil.ReadFile("conf.yaml")
    if err != nil {
        log.Printf("yamlFile.Get err   #%v ", err)
    }
    err = yaml.Unmarshal(yamlFile, c)
    if err != nil {
        log.Fatalf("Unmarshal: %v", err)
    }

    return c
}

Answer 1

your yaml file must be

hits: 5
time: 5000000

your code should look like this:

package main

import (
    "fmt"
    "gopkg.in/yaml.v2"
    "io/ioutil"
    "log"
)

type conf struct {
    Hits int64 `yaml:"hits"`
    Time int64 `yaml:"time"`
}

func (c *conf) getConf() *conf {

    yamlFile, err := ioutil.ReadFile("conf.yaml")
    if err != nil {
        log.Printf("yamlFile.Get err   #%v ", err)
    }
    err = yaml.Unmarshal(yamlFile, c)
    if err != nil {
        log.Fatalf("Unmarshal: %v", err)
    }

    return c
}

func main() {
    var c conf
    c.getConf()

    fmt.Println(c)
}

the main error was capital letter for your struct.
