Yaml 輸入：Tasks: - task: name: 123 retry: 5 next: 123 - task: name: 123 retry: 5 next: 123代碼：package mainimport ( "fmt" "io/ioutil" "os" "gopkg.in/yaml.v2")type Tasks []struct { Task Task `yaml:"task"`}type Task struct { Name string `yaml:"name"` Retry int `yaml:"retry"` Next string `yaml:"next"`}func main() { var w Tasks wfyaml, _ := os.Open(".yaml") byteValue, _ := ioutil.ReadAll(wfyaml) yaml.Unmarshal(byteValue, &w) fmt.Printf("%+v\n", w)}輸出：[]我無法弄清楚問題的原因是什么。我已經(jīng)檢查了我能做的。

Tasks您錯(cuò)過了結(jié)構(gòu)（游樂場(chǎng)）中的頂層（）：
package main
import (
"fmt"
"gopkg.in/yaml.v2"
)
const yamlStr = `Tasks:
- task:
name: 123
retry: 5
next: 123
- task:
name: 123
retry: 5
next: 123`
type File struct {
Tasks Tasks `yaml:"Tasks"`
}
type Tasks []struct {
Task Task `yaml:"task"`
}
type Task struct {
Name string `yaml:"name"`
Retry int `yaml:"retry"`
Next string `yaml:"next"`
}
func main() {
var w File
yaml.Unmarshal([]byte(yamlStr), &w)
fmt.Printf("%+v\n", w)
}
