您提供的Yaml令牌中包含错误。在此处验证代码中使用的Yaml https://prebeautify.org/yaml-
validator/cbaabb32
之后，创建结构类型的变量结果而不是数组。因为您使用的Yaml正在使用Runners数组和api_version创建一个结构。
这个
var runners []Result
应该
var runners Result
因为因为struct不是切片。为yaml中使用的功能名称获取命令列表。您需要遍历runners数组以查找函数名称并获取该函数的命令值。下面是工作代码：
package mainimport ( "fmt" "log" "gopkg.in/yaml.v2")var runContent = []byte(`api_ver: 1runners: - name: function1 type: - command: spawn child process - command: build - command: gulp - name: function2 type: - command: run function 1 - name: function3 type: - command: ruby build - name: function4 type: - command: go build`)type Result struct { Version string `yaml:"api_ver"` Runners []Runners `yaml:"runners"`}type Runners struct { Name string `yaml:"name"` Type []Command `yaml:"type"`}type Command struct { Command string `yaml:"command"`}func main() { var runners Result // parse mta yaml err := yaml.Unmarshal(runContent, &runners) if err != nil { log.Fatalf("Error : %v", err) } commandList := getCommandList("function1", runners.Runners) fmt.Printf("%+v", commandList)}func getCommandList(name string, runners []Runners) []Command { var commandList []Command for _, value := range runners { if value.Name == name { commandList = value.Type } } return commandList}操场上的例子
