How to unmarshal YAML in Go
问题
我在Go语言中很难解析这段YAML代码。我得到的错误是“无法将!!seq解组为map[string][]map[string][]string”。我尝试了各种类型的映射，但都没有成功（例如map[string]string；[]map[string]string等）。
import ("gopkg.in/yaml.v1""io/ioutil")type AppYAML struct {Runtime string `yaml:"runtime,omitempty"`Handlers map[string][]map[string][]string `yaml:"handlers,omitempty"`Env_Variables map[string]string `yaml:"env_variables,omitempty"`}func main() {s := `runtime: gohandlers:- url: /.*runtime: _go_appsecure: alwaysenv_variables:something: 'test'`var a AppYAMLif err = yaml.Unmarshal([]byte(s), &a); err != nil {log.Error(err)return}}

I have a hard time to unmarshal this piece of YAML in Go. The error I'm getting is cannot unmarshal !!seq into map[string][]map[string][]string . I've tried all kind of maps with no success (map[string]string ; []map[string]string and so on)
import ("gopkg.in/yaml.v1""io/ioutil")type AppYAML struct {Runtime string `yaml:"runtime,omitempty"`Handlers map[string][]map[string][]string `yaml:"handlers,omitempty"`Env_Variables map[string]string `yaml:"env_variables,omitempty"`}func main() {s := `runtime: gohandlers:- url: /.*runtime: _go_appsecure: alwaysenv_variables:something: 'test'`var a AppYAMLif err = yaml.Unmarshal([]byte(s), &a); err != nil {log.Error(err)return}}

将类型声明更改为以下内容：
type AppYAML struct {Runtime string `yaml:"runtime,omitempty"`Handlers []map[string]string `yaml:"handlers,omitempty"`Env_Variables map[string]string `yaml:"env_variables,omitempty"`}
请注意，我已经将引号从yaml:"..."更改为yaml:"..."，以使其符合Go语言的语法要求。
英文:
Change type declaration to this:
type AppYAML struct {Runtime string `yaml:"runtime,omitempty"`Handlers []map[string]string `yaml:"handlers,omitempty"`Env_Variables map[string]string `yaml:"env_variables,omitempty"`}
