在golang中关闭会话的Softlayer API？

import (
    "fmt"
    "github.com/softlayer/softlayer-go/session"
    "github.com/softlayer/softlayer-go/services"
)

sess := session.New(username, apiKey)

serviceClient := services.GetAccountService(sess)

_, err := serviceClient.Logout()
if err != nil {
    fmt.Println("关闭会话失败：", err)
    return
}
fmt.Println("会话已成功关闭")

package main

import (
    "fmt"
    "github.com/softlayer/softlayer-go/session"
    "github.com/softlayer/softlayer-go/services"
)

func main() {
    username := "your_username"
    apiKey := "your_api_key"

    sess := session.New(username, apiKey)
    serviceClient := services.GetAccountService(sess)

    _, err := serviceClient.Logout()
    if err != nil {
        fmt.Println("关闭会话失败：", err)
        return
    }
    fmt.Println("会话已成功关闭")
}
