是否可以将输出更改为实际的字符串？

Question

我创建了这个函数来输出跨区域的 aws 账户的所有账户 ID，但我得到的输出非常难以理解尝试像 c++ 中那样取消引用package mainimport (    "fmt"    //"github.com/aws/aws-lambda-go/lambda"   // "github.com/aws/aws-sdk-go/aws"    "github.com/aws/aws-sdk-go/aws/awserr"    //"github.com/aws/aws-sdk-go/aws/credentials/stscreds"    "github.com/aws/aws-sdk-go/aws/session"    "github.com/aws/aws-sdk-go/service/organizations")func main()  {    listAccounts()}func listAccounts() {    sess := session.Must(session.NewSession())    svc := organizations.New(sess)    input := &organizations.ListAccountsInput{}    result, err := svc.ListAccounts(input)    if err != nil {        if aerr, ok := err.(awserr.Error); ok {            switch aerr.Code() {            case organizations.ErrCodeAccessDeniedException:                fmt.Println(organizations.ErrCodeAccessDeniedException, aerr.Error())            case organizations.ErrCodeAWSOrganizationsNotInUseException:                fmt.Println(organizations.ErrCodeAWSOrganizationsNotInUseException, aerr.Error())            case organizations.ErrCodeInvalidInputException:                fmt.Println(organizations.ErrCodeInvalidInputException, aerr.Error())            case organizations.ErrCodeServiceException:                fmt.Println(organizations.ErrCodeServiceException, aerr.Error())            case organizations.ErrCodeTooManyRequestsException:                fmt.Println(organizations.ErrCodeTooManyRequestsException, aerr.Error())            default:                fmt.Println(aerr.Error())            }        } else {        // Print the error, cast err to awserr.Error to get the Code and        // Message from an error.        fmt.Println(err.Error())        }    return}    // fmt.Println(result.Accounts)    var accountList []*string    for _, accountId := range result.Accounts {        accountList = append(accountList, accountId.Id)    }    fmt.Println(accountList)}

*string当你真正只需要s 时，你却在服用s string。这是一个简单的更改，可以取消引用从 AWS SDK 返回的指针（它对所有内容都使用指针以实现可空性）：

var accountList []string

for _, accountId := range result.Accounts {

    accountList = append(accountList, *accountId.Id)

}

fmt.Println(accountList)
