Question

我一直在尝试解析这个JSON数据，但由于某些原因无法解决。我的代码和JSON如下。我希望它在页面中显示每个页面并将其打印到控制台。代码有效，它只是在if let pages = JSON []之后实际上没有处理任何东西（或者看起来如此），因为它不会在页面中打印我的for循环或页面。代码和JSON如下。

这是我正在尝试解析的JSON数据：

                    //println(json)

                    if let pages = json["pages"] as? [[String : AnyObject]] {


                        println("stat summary working")


                        for page in pages {

                            println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n")

                            println(page)

URL只是显示我在代码上方发布的JSON数据的URL。

Answer 1

您没有正确访问json，我的意思是您在json["pages"]中提供的路径不是有效路径。仔细看看数据; {"43993167":{"summonerId":43993167,"pages"

你有一个对象，其中第一个是另一个名为/ key“43993167”的对象，其下面有pages。因此，您需要json["43993167"]["pages"]才能访问您尝试访问的数据。

话虽这么说，我只能假设你正在处理一个召唤者对象字典，其中关键是召唤者，然后你试图查看他们的符文页面数据...更好的设计将是反序列化为反映该结构的东西（如召唤器对象的字典）然后迭代该字典。最终你有这样的事情;

rootLevelDictionary[]
    summoner
        summonerId
        pages[]
           id
           name
           current
           slots[]
              runeObject
                 runeSlotId
                 runeId

这是你的json的基本结构。如果我有时间，我会把它变成一个有效的json模式，但希望这足以让你畅通无阻。

Answer 2

因为json["pages"]不存在，所以它嵌套在内部＆＃34; 43993167＆＃34;。

您需要

json["43993167"]["pages"]

Answer 3

终于开始工作了。不得不稍微改变一下代码。以下是它现在的样子：

let task = session.dataTaskWithURL(url) { data, response, error in

        if let httpResponse = response as? NSHTTPURLResponse {

            switch httpResponse.statusCode {

            case 200..<300:

                if let json = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary, let include = json.objectForKey("\(self.idNumber)") as? NSDictionary {

                    println("json working")

                    //println(json)

                    if let pages = include["pages"] as? [[String : AnyObject]] {


                        println("stat summary working")


                        for page in pages {

                            println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n")

                            println(page)


                        }
                    }
                }


            default: println("Not Ok")

            }
        }
    }

    task.resume()
