Question

以下是JSON数据的 abridge 列表：

let json = JSON(data: response.result.value!).dictionary
self?.processData(json: json!)
...
...
func processData(json:[String:Any]) {
        let myList = json["list"]
...
}

<小时/> 我怎么能破译这个？
该列表显示它是'SwiftJSON.Type.array'（见上文）
但以下说它不是：

(lldb) po type(of:myList)
Swift.Optional<Any>

它看起来像一组字典。所以我试图这样做：

(lldb) po myList as [[String:String]]
error: Execution was interrupted, reason: signal SIGABRT.
The process has been returned to the state before expression evaluation.

怎么能得到这个对象的元素？
...或正确地将其转换为字符串字典数组以进行解密？

<小时/> 跟进：

if let myList = json["list"] as? [[String:Any]] {
            print("Do Something")
}

'if'语句失败。

Answer 1

您的myList确定字典数组，但您需要将其投放到[[String:Any]]而非[[String:String]]，因为其Dictionary包含number和{{1}两者都是一个值，所以简单地将它转换为string适用于你的。

[[String:Any]]

Answer 2

根据建议，我打印出数据：

func getData(str:String) {
        Alamofire.request(MashapeRouter.getDefinition(str))
            .responseData { response in
                let json = JSON(data: response.result.value!).dictionary
                print("\n-------------\n")
                print(json!)
                return;
        }
}

我得到以下内容：

 -------------

["result_type": exact, "sounds": [
  "http:\/\/media.urbandictionary.com\/sound\/turkey-7377.mp3",
  "http:\/\/wav.urbandictionary.com\/turkey-21188.wav",

    "thumbs_up" : 1160,
    "word" : "turkey",
    "permalink" : "http:\/\/turkey.urbanup.com\/1528701",
    "current_vote" : ""
  },…
], 

"tags": [
  "thanksgiving",
  "chicken",
  "sex",
  "turkish",
  "turk",
  "food",
  "gobble",
  "duck",
  "ham",
  "sandwich"
]]

基于此输出，我尝试了以下内容：

po json!["list"]?[0]["example"].string! 
▿ Optional<String>
  - some : "If through some crazy events Asia and Europe went to war, they\'d both bomb Turkey."

所以我越来越近了：

  if let myString = json!["list"]?[0]["example"].string {
                    print("myString= \(myString)")
                }

......我从中得到以下内容：

myString= If through some crazy events Asia and Europe went to war, they'd both bomb Turkey.
(lldb)

......所以我显然需要做的就是清理这一切;避免'厄运金字塔'： - 多个可选的展开。

如何将可选<any>解密为字典数组？
