Alamofire 4.0.0：[String：String]不能转换为[String：Any]＆amp;没有更多上下文，请求是模糊的

Question

我正在将Alamofire更新为4.0.0 Beta 1，将XCode 8更新为Beta 6.首先，此代码出现[String:String] is not convertible to [String : Any]错误

let parameter = [
        "scope":"\(scope)",
        "client": "\(clientId)"
    ]
Alamofire.request(link, withMethod: .POST, parameters: parameter, encoding: .json).responseJSON

在我将[String：Any]添加到参数后，错误消失了，但创建了新错误：Expression type 'Request' is ambiguous without more context

let parameter:[String:Any] = [
        "scope":"\(scope)",
        "client": "\(clientId)"
    ]

将.JSON替换为.JSONEncoding.default
