ios - if 条件在 swift ios 的 json 响应中

Question

如果服务器响应是(结果=“帐户存在”)，那么我可以做一些事情。但是当我比较结果时，它给出一个错误:“二元运算符‘==’不能应用于‘Any’和‘String’类型的操作数”。

let dataTask = session.dataTask(with: url!, completionHandler: { (data, response, error) -> Void in

        do
        {
            let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! NSDictionary

            print("JSON : \(json)")

            if let dataDic = json.value(forKey: "data")
           {
            print("dataDic: \(dataDic)")

            if let Result = (dataDic as AnyObject).value(forKey: "Result")
            {
            print("Result: \(Result)")

                if (Result ("Account Exists")) == 0
                {
                    //... DO Something
                }
            }
            }
        }
        catch
        {
            print("Catch exception")
        }
    })
    dataTask.resume()
}

以纯粹快捷的方式..您的“数据”是一个数组，顶级 json 是字典

   do
    {
       let json = try JSONSerialization.jsonObject(with: data!, options: []) as! [String:Any]

       if let data = json["data"] as? [[String:String]] {
           if let resultString = data.first?["Result"] as? String{
               if resultString == "Account Exists"{
                   //... DO Something
               }
               else if resultString == "Unauthorized Access" {
                   //... DO Something
               }
           }
       }
    }
    catch{
        print("Catch exception")
    }
