如何在 Go 中安全地將 YAML 轉換為 JSON，而不遺失資料完整性？

import (
    "fmt"
    "log"

    "github.com/go-yaml/yaml"
    "encoding/json"
)

func convert(i interface{}) interface{} {
    switch x := i.(type) {
    case map[interface{}]interface{}:
        m2 := map[string]interface{}{}
        for k, v := range x {
            m2[k.(string)] = convert(v)
        }
        return m2
    case []interface{}:
        for i, v := range x {
            x[i] = convert(v)
        }
    }
    return i
}

func main() {
    // Define the YAML string
    const s = `Services:
    -   Orders: 
        -   ID: $save ID1
            SupplierOrderCode: $SupplierOrderCode
        -   ID: $save ID2
            SupplierOrderCode: 111111
    `

    // Unmarshal the YAML string into an empty interface
    var body interface{}
    if err := yaml.Unmarshal([]byte(s), &body); err != nil {
        log.Fatal(err)
    }

    // Recursively convert the interface to a map[string]interface{}
    body = convert(body)

    // Marshal the converted interface into a JSON string
    if b, err := json.Marshal(body); err != nil {
        log.Fatal(err)
    } else {
        fmt.Println("Converted JSON:", string(b))
    }
}

Converted JSON: {"Services":[{"Orders":[
    {"ID":"$save ID1","SupplierOrderCode":"$SupplierOrderCode"},
    {"ID":"$save ID2","SupplierOrderCode":111111}]}]}
