类型Any没有下标成员Swift 3.0 [英] Type Any has no subscript members Swift 3.0

问题描述

尝试转换功能使其与Swift 3.0兼容.必须将参数json从AnyObject更改为Any:

Trying to convert a function to make it Swift 3.0 compatible. Had to change the parameter json from AnyObject to Any:

fileprivate func checkForAuthorizationFailure(_ json: Any) -> Bool {

        let responseMessage = json["response"]! as? String
        if responseMessage == "Unauthorized. Invalid token or email." {
            return true
        }

        return false
    }

但是在以下行:let responseMessage = json["response"]! as? String我现在收到错误: "Type Any没有下标成员" .我在这里做错什么了?

However at the line: let responseMessage = json["response"]! as? String I am now getting the error: "Type Any has no subscript members". What am I doing wrong here?

推荐答案

在使用下标之前，您必须将Any强制转换为AnyObject.

You have to cast Any to AnyObject before using subscript.

fileprivate func checkForAuthorizationFailure(_ json: Any) -> Bool {

    let responseMessage = (json as AnyObject)["response"]! as? String
    if responseMessage == "Unauthorized. Invalid token or email." {
        return true
    }

    return false
}
