【问题描述】：

谁能告诉我如何从这个 JSON 中获取数据？

这是我的代码，后面是 JSON

let URL = "URL"
Alamofire.request(URL).responseJSON
 response in
print("HereBegins: = \(response)")
let result = response.result.value as? [String:Any]

返回的 json 是...

【问题讨论】：

为什么这被否决了？最好解释一下显而易见的事情并说......“我到处寻找，其他人的解决方案对我不起作用！请有人帮忙。”出于某种原因，我无法从此 JSON 访问任何内容。当我打印“结果”时，我可以得到一些东西，但我什至做不到结果！[“项目”]但我可以走得更远。

我没有投反对票，但 JSON（顺便说一下不是 JSON）是一团糟。我们鼓励您正确格式化您的代码。

感谢您的信息。我从沃尔玛得到了 JSON 或其他任何东西，哈哈，他们称它为 JSON，所以我不知道它是什么。

想通了。

                    if let resData = result["items"].arrayObject 
                        arrRes = resData as! [[String:AnyObject]]
                        for element in arrRes[0]
                        
                            print(element)
                        
                        print(arrRes[0]["name"])
