问题描述

func getKeyNameFromDeploymentAndSubnet(subnetType SubnetType, deploymentType DeploymentType, keyNameMap map[SubnetType]string) string {
    if (deploymentType == NoDeployment || deploymentType == PDBAWindows || deploymentType == AgentDeployment) {
        return keyNameMap[subnetType]
    }
    else if (deploymentType == AnsibleDeployment) {
        return "bar"
    }
    return "foo"
}

在第一个if语句中,在函数错误结束时出现缺少返回的错误.如果删除else if语句,则不会出现此错误.我要去哪里错了?

In the first if statement, I get an error of missing return at end of function error. I don't get this error if I remove the else if statement. Where am I going wrong?

推荐答案

您会收到此错误,因为else语句必须与第一个条件的结尾}在同一行.

You get this error because else statement must be on the same line as the closing } of the first condition.

func getKeyNameFromDeploymentAndSubnet(subnetType SubnetType, deploymentType DeploymentType, keyNameMap map[SubnetType]string) string {
    if deploymentType == NoDeployment || deploymentType == PDBAWindows || deploymentType == AgentDeployment {
        return keyNameMap[subnetType]
    } else if deploymentType == AnsibleDeployment {
        return "bar"
    }
    return "foo"
}
