Question

将Golang与AWS开发工具包Cloudformation一起使用到CreateChangeSet（）并难以确定此ValidationError的原因：

error on CreateChangeSet: ValidationError:
StackName must be specified if ChangeSetName is not specified as an ARN.
        status code: 400

有人知道执行变更集时如何克服此验证错误吗？


    changesetName := `some_unique_value_<timestamp>`
    stackARN := `arn:aws:cloudformation:us-west-2:<accountID>:stack/sample-stack1/<GUID>`
    changesetName := instance.GetChangeSetName() // example:
    CreateChangeSetInput := &cloudformation.CreateChangeSetInput{
        StackName:     aws.String(stackARN),          // required field.
        ChangeSetName: aws.String(changesetName), // must be a unique value
        ChangeSetType: aws.String("UPDATE"),  // stack exists. using UPDATE
        TemplateBody:  aws.String(templateBody), // cfn template
        Parameters:    params}  // cfn paramaters

    // Issue AWS CreateChangeSet API call
    log.Println("Issuing AWS CreateChangeSet() API call")
    _, err = svc.CreateChangeSet(CreateChangeSetInput)
    if err != nil {
        return fmt.Errorf("Got error on CreateChangeSet: %v", err.Error())
    }

    ExecuteChangeSetInput := &cloudformation.ExecuteChangeSetInput{
        ChangeSetName: aws.String(changesetName)}

    // Issue AWS CreateChangeSet API call
    log.Println("Issuing AWS CreateChangeSet() API call")
    _, err = svc.ExecuteChangeSet(ExecuteChangeSetInput)
    if err != nil {
        return fmt.Errorf("Got error on CreateChangeSet: %v", err.Error())
    }

发布后仅几分钟，我意识到该错误实际上是来自第二个api调用。在ExecuteChangeSet调用中提供相同的StackName可解决验证错误：

ExecuteChangeSetInput := &cloudformation.ExecuteChangeSetInput{
        ChangeSetName: aws.String(changesetName),
        StackName:     aws.String(stackARN)}

如果未将ChangeSetName指定为ARN，则必须指定AWS开发工具包CreateChangeSet ValidationError StackName
