尝试将Yaml数据转换为结构时输出为空 [英] Empty output while trying to convert a yaml data into a struct

问题描述

我正在尝试将Yaml数据转换为结构并打印.我为此程序获得的输出为空.

Im trying to convert a yaml data into a struct and print it. The output I get for this program is empty.

package main

import (
"fmt"

"gopkg.in/yaml.v2"
)

type example struct {
    variable1 string
    variable2 string
}

func main() {
    var a example
    yaml.Unmarshal([]byte("variable1: asd\nvariable2: sdcs"), &a)
    fmt.Println(a.variable1)
}

推荐答案

文档表示Unmarshal表示

仅在导出结构化字段时将其解组(首字母大写)，并且使用小写的字段名称作为默认键将其解组.

Struct fields are only unmarshalled if they are exported (have an upper case first letter) and are unmarshalled using the field name lowercased as the default key.

因此，大写您的struct元素是正确的事情.

So capitalizing your struct elements is the right thing to do.

type example struct {
    Variable1 string
    Variable2 string
}
