解组 yaml

Question

我在尝试使用 gopkg.in/yaml.v2 读取此 yaml 时遇到问题。错误是：

line 1: cannot unmarshal !!seq into main.Owners

读取文件：

content, _ := ioutil.ReadFile("apartments.yml")

owners := Owners{}
err := yaml.Unmarshal(content, &owners)
if err != nil {
    fmt.Printf("%s\n", err)
}

我的结构看起来像：

type Owners struct {
    Owner []struct {
        Apartment  string `yaml:"apartment"`
        PaymentIds []string `yaml:"paymentIds"`
    } `yaml:"owner"`
}

数据：

- owner:
    apartment: 002
    paymentIds:
      - KB002
- owner:
    apartment: 003
    paymentIds:
      - KB003
- owner:
    apartment: 004
    paymentIds:
      - KB004
- owner:
    apartment: 005
    paymentIds:
      - KB005

Answer 1

使用Owners 的结构切片而不是Owner，因为根据您的yaml，每个Owners 都有owner 节点。

type Owners []struct {
    Owner struct {
        Apartment  string `yaml:"apartment"`
        PaymentIds []string `yaml:"paymentIds"`
    } `yaml:"owner"`
}
