Go 解析yaml返回空对象

我有以下yaml需要解析为struct。 在builds属性中，我在调试时得到了空值，我在这里缺少什么

我使用“gopkg.in/yaml.v2”

结构是

type Runs struct {
    Name       string
    Type       string
    Path       string     `yaml:"path,omitempty"`
    Builds   []Builds `yaml:”builds,omitempty"`
}

type Builds struct {
    Name       string     `yaml:"name,omitempty"`
    Properties Properties `yaml:"properties,omitempty"`
}

type Properties map[string]string

---

确保yaml文件的格式正确。看看这个

下面的代码运行良好

package main

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

type Runs struct {
    Name   string
    Type   string
    Path   string   `yaml:"path,omitempty"`
    Builds []Builds `yaml:”builds,omitempty"`
}

type Builds struct {
    Name       string     `yaml:"name,omitempty"`
    Properties Properties `yaml:"properties,omitempty"`
}

type Properties map[string]string

func main() {
    data := `builds: 
  - 
    name: db
    properties: 
      JBR_CONFIG_RESOURCE_CONFIG: "[META-INF/context.xml: {\"service_name\" : \"~{h-container}\"}]"
      TEST2: aaaa
name: srv
path: srv
type: java
`

    runs := Runs{}

    err := yaml.Unmarshal([]byte(data), &runs)
    if err != nil {
        log.Fatalf("error: %v", err)
    }
    fmt.Printf("--- t:\n%v\n\n", runs)
    d, err := yaml.Marshal(&runs)
    if err != nil {
        log.Fatalf("error: %v", err)
    }
    fmt.Printf("--- t dump:\n%s\n\n", string(d))
}

我希望这有帮助，，你应该让你的yaml格式化成这样

name: srv
builds:
  -
    name: db
    properties:
      JBR_CONFIG_RESOURCE_CONFIG: "[META-INF/context.xml:
      {\"service_name\" : \"~{h-container}\"}]"
      TEST2: aaaa
path: srv
type: java

但是我想得到更多的这个对象，你需要把它们组合在一个参数中。它可以像这样

runs:
  -
    name: srv
    builds:
      -
        name: db
        properties:
          JBR_CONFIG_RESOURCE_CONFIG: "[META-INF/context.xml:
          {\"service_name\" : \"~{h-container}\"}]"
          TEST2: aaaa
    path: srv
    type: java
  -
    name: srv2
    builds:
      -
        name: db2
        properties:
          JBR_CONFIG_RESOURCE_CONFIG: "[META-INF/context.xml:
          {\"service_name\" : \"~{h-container}\"}]"
          TEST2: aaaa2
    path: srv2
    type: java2

package main

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

type Document struct {
    Runs []Runs `yaml:"runs,omitempty"`
}
type Runs struct {
    Name   string   `yaml:"name,omitempty"`
    Type   string   `yaml:"type,omitempty"`
    Path   string   `yaml:"path,omitempty"`
    Builds []Builds `yaml:"builds,omitempty"`
}

type Builds struct {
    Name       string            `yaml:"name,omitempty"`
    Properties map[string]string `yaml:"properties,omitempty"`
}

func main() {

    var document Document
    reader, err := os.Open("demo.yml")
    if err != nil {
        log.Fatal(err)
    }
    buf, _ := ioutil.ReadAll(reader)
    yaml.Unmarshal(buf, &document)
    if err := yaml.Unmarshal(buf, &document); err != nil {
        fmt.Print(err)
        os.Exit(1)
    }
    fmt.Println(document)
}

然后在你的代码中可能是这样的

runs:
  -
    name: srv
    builds:
      -
        name: db
        properties:
          JBR_CONFIG_RESOURCE_CONFIG: "[META-INF/context.xml:
          {\"service_name\" : \"~{h-container}\"}]"
          TEST2: aaaa
    path: srv
    type: java
  -
    name: srv2
    builds:
      -
        name: db2
        properties:
          JBR_CONFIG_RESOURCE_CONFIG: "[META-INF/context.xml:
          {\"service_name\" : \"~{h-container}\"}]"
          TEST2: aaaa2
    path: srv2
    type: java2

package main

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

type Document struct {
    Runs []Runs `yaml:"runs,omitempty"`
}
type Runs struct {
    Name   string   `yaml:"name,omitempty"`
    Type   string   `yaml:"type,omitempty"`
    Path   string   `yaml:"path,omitempty"`
    Builds []Builds `yaml:"builds,omitempty"`
}

type Builds struct {
    Name       string            `yaml:"name,omitempty"`
    Properties map[string]string `yaml:"properties,omitempty"`
}

func main() {

    var document Document
    reader, err := os.Open("demo.yml")
    if err != nil {
        log.Fatal(err)
    }
    buf, _ := ioutil.ReadAll(reader)
    yaml.Unmarshal(buf, &document)
    if err := yaml.Unmarshal(buf, &document); err != nil {
        fmt.Print(err)
        os.Exit(1)
    }
    fmt.Println(document)
}

请分享您尝试过的内容…谢谢1+，我的yaml是有效的，可能问题的副本更改了它，但我能够解析它，否则我猜如果解组失败，我会出错…知道它可能是什么吗？谢谢1+，我的yaml是有效的，可能问题的副本更改了它，但我能够解析它，否则，我想我会得到和错误，如果解组将失败…你知道它可能是什么吗？是否更改了结构中的某些内容？如果未明确检查

yaml.Unmarshal

是否返回错误，则代码将以空

运行。我在我的代码中添加了这个，如果检查，确定你可以发送给我，我可以通过聊天或其他方式发送吗？让我们。
