如何在 Go 模板中访问范围内的范围？

模板：

{{range .Resume.Skills}}    
    {{.Name}}
    {{.Level}}
    {{range $item, $key := .Keywords}}
            {{$key}}
            {{$item}}
    {{end}}
{{end}}

结构：

type SkillsInfo struct {
    Name     string
    Level    string
    Keywords []KeywordsInfo
}

type KeywordsInfo struct {
    Keyword string
}

我可以看到的结果是 {}。如何访问模板中的嵌套对象？

- -更新 - ：

type ResumeJson struct {
    Basics       BasicsInfo
    Work         []WorkInfo
    Volunteer    []VolunteerInfo
    Education    []EducationInfo
    Awards       []AwardsInfo
    Publications []PublicationsInfo
    Skills       []SkillsInfo
    Languages    []LaunguagesInfo
    Interests    []InterestsInfo
    References   []ReferencesInfo
}

现在看到的结果：

Web 开发大师 {} 0 {} 1 {} 2

我解析的 ans JSON：

我正在尝试使用Docker API和Docker Go库(https://github.com/docker/engine-api/)构建Docker镜像.代码示例:

package main
import (
    "fmt"
    "github.com/docker/engine-api/client"
    "github.com/docker/engine-api/types"
    "golang.org/x/net/context"
)
func main() {
    defaultHeaders := map[string]string{"User-Agent": "engine-api-cli-1.0"}
    cli, err := client.NewClient("unix:///var/run/docker.sock", "v1.22", nil, defaultHeaders)
    if err != nil {
        panic(err)
    }
    fmt.Print(cli.ClientVersion())
    opt := types.ImageBuildOptions{
        CPUSetCPUs:   "2",
        CPUSetMems:   "12",
        CPUShares:    20,
        CPUQuota:     10,
        CPUPeriod:    30,
        Memory:       256,
        MemorySwap:   512,
        ShmSize:      10,
        CgroupParent: "cgroup_parent",
        Dockerfile:   "dockerSrc/docker-debug-container/Dockerfile",
    }
    _, err = cli.ImageBuild(context.Background(), nil, opt)
    if err == nil || err.Error() != "Error response from daemon: Server error" { …
