错误地解组Yaml？

Question

I am using yaml to decode yaml file. However, the result is not as expected. The EncryptKey is not extracted. This is my test code:

package main

import (
    "fmt"
    "log"

    "gopkg.in/yaml.v2"
)

var data = `
port: 8080
encryptKey: "jfgjfgkfgd"
`

type Config struct {
    Port       int    `json:"port"`
    EncryptKey string `json:"encryptKey"`
}

func main() {
    t := Config{}

    err := yaml.Unmarshal([]byte(data), &t)
    if err != nil {
        log.Fatalf("error: %v", err)
    }
    fmt.Printf("--- t:
%v

", t)
}

I got the result like this:--- t: {8080 }

It's my carelessness. I should use the tag yaml instead of json.

You are using json tags instead of yaml tags. Fix your struct definition like this:

type Config struct {
    Port       int    `yaml:"port"`
    EncryptKey string `yaml:"encryptKey"`
}
