Question

我试图从嵌套字典数组中获取数据，这是JSON响应的结果。

func fetchData() {
    let urlString = "https://global.api.pvp.net/api/lol/static-data/na/v1.2/champion?api_key=\(self.apiKey)"
    let url = URL(string: urlString)

    URLSession.shared.dataTask(with:url!) { (data, response, error) in
        if error != nil {
            print(error ?? "ERROR!")
        } else {
            do {

                let parsedData = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! [String:Any]
                print(parsedData)
                print(parsedData["type"] ?? "")
                print(parsedData["version"] ?? "")

                print(type(of: parsedData))
                print(type(of: parsedData["data"]!))


                //ERROR HERE.
                //"Cannot subscript a value of type '[String, Any]' with an index of type '(String, (String, Any).Type)'
                let innerItem = parsedData["Aatrox", (String, Any)]





            } catch let error as NSError {
                print(error)
            }
        }

    }.resume()

以下是印刷品：

["type": champion, "version": 7.4.3, "data": {
Aatrox =     {
    id = 266;
    key = Aatrox;
    name = Aatrox;
    title = "the Darkin Blade";
};
Ahri =     {
    id = 103;
    key = Ahri;
    name = Ahri;
    title = "the Nine-Tailed Fox";
};
Akali =     {
    id = 84;
    key = Akali;
    name = Akali;
    title = "the Fist of Shadow";
};
Alistar =     {
    id = 12;
    key = Alistar;
    name = Alistar;
    title = "the Minotaur";
};
}]

champion
7.4.3

Dictionary<String, Any>
__NSDictionaryI

我正在努力获得＆＃34; id＆＃34;为＆＃34; Aatrox＆＃34;。

我将如何做到这一点？
是因为parsedData的类型[＆＃34;数据＆＃34;]！是__NSDictionaryI ??

感谢您的帮助。

Answer 1

首先，您需要提取data词典，然后访问其他词典。

do {
    let parsedData = try JSONSerialization.jsonObject(with: data!, options: []) as! [String:Any]
    if let passDic = parsedData["data"] as? [String:Any],
       let innerItem = passDic["Aatrox"] as? [String: Any] {
          print(innerItem)
    }

} catch  {
     print(error)
}

Answer 2

似乎应该是let innerItem: [String: Any] = parsedData["Aatrox"]

Answer 3

int seconds = 5;
final short[] data = new short[samples * seconds];
recorder.readSamples(data, 0, data.length);

这件事对我有用..
