我絕對(duì)沒有得到這個(gè)。這是給定的 yaml 文件items: - item1: one: "some" two: "some string" - item2: one: "some" two: "some string"和一個(gè)配置：type Item struct { one string two string}type conf struct { Items map[string]Item}func (c *conf) getConfig(filename string) *conf { yamlFile, err := ioutil.ReadFile(filename) if err != nil { log.Printf("yamlFile.Get err #%v ", err) } err = yaml.Unmarshal(yamlFile, &c) if err != nil { log.Fatalf("Unmarshal: %v", err) } //c.Items = make(map[string]Items) return c}我在用gopkg.in/yaml.v2出現(xiàn)此錯(cuò)誤：Unmarshal: yaml: unmarshal errors: line 6: cannot unmarshal !!seq into map[string]application.Item請(qǐng)幫助我理解我在這里做錯(cuò)了什么。我已經(jīng)到處搜索了。提前致謝。

首先，您需要將 YAML 更改為
items:
item1:
one: "some"
two: "some string"
item2:
one: "some"
two: "some string"
然后，在你的代碼中
type Config struct {
Items map[string]Item
}
type Item struct {
One string
Two string
}
然后與
fmt.Printf("%+v\n", c.Items)
你將會(huì)有
map[item1:{One:some Two:some string} item2:{One:some Two:some string}]

您的映射存在多個(gè)問題：
Item不導(dǎo)出結(jié)構(gòu)成員。您必須導(dǎo)出它們：
type Item struct {
One string `yaml:"one"`
Two string `yaml:"two"`
}
Items是Items的映射數(shù)組
type conf struct {
Items []map[string]Item `yaml:"items"`
}

我的場(chǎng)合是，我將 yaml 定義如下：
idl:
protobuf:
executable: protoc
version_min: v3.6.0
version_cmd: "protoc --version | awk '{ print $2 }'"
install_cmd: ""
fallback: "please install protoc first, see: https://github.com/protocolbuffers/protobuf"
flatbuffers:
executable: flatc
version_min: 2.0.0
version_cmd: "flatc --version | awk '{ print $3 }'"
install_cmd: ""
fallback: "please install flatc first, see: https://google.github.io/flatbuffers/flatbuffers_guide_building.html"
我想將yaml轉(zhuǎn)換為Config類型，定義為：
type Dependency struct {
Executable string `yaml:"executable"`
VersionMin string `yaml:"version_min"`
VersionCmd string `yaml:"version_cmd"`
InstallCmd string `yaml:"install_cmd"`
Fallback string `yaml:"fallback"`
}
type Config struct {
IDL map[string]*Dependency `yaml:"idl"`
...
}
它報(bào)告一個(gè)錯(cuò)誤：yaml: unmarshal errors: line 5: cannot unmarshal !!seq into map[string]*config.Dependency。
我搜索了相關(guān)問題和yaml教程，我認(rèn)為我的yaml文件是可以的。我真的很困惑。
