我将如何与没有钥匙的JSON合作：使用urlsession在Swift中的价值对？

我正在尝试在返回的JSON中访问每个标题。这是JSON

[
    "Hyouka",
    "Youjo Senki",
    "Bungou Stray Dogs 2nd Season",
    "Fullmetal Alchemist: Brotherhood",
    "Tokyo Ghoul √A",
    "Mahouka Koukou no Rettousei",
    "Boku wa Tomodachi ga Sukunai NEXT",
    "Joker Game",
    "Avatar: The Last Airbender",
    "Charlotte"
]

，这只是一堆值，我没有钥匙来构建我的模型对象。这就是我打算这样做的方式，

struct AllNames {
    
    let name: String   
}

但是没有关键名称可以访问。您将如何访问此数据将每个名称打印到Swift中的控制台？

原文

I am trying to access each title in a returned json. This is the JSON

[
    "Hyouka",
    "Youjo Senki",
    "Bungou Stray Dogs 2nd Season",
    "Fullmetal Alchemist: Brotherhood",
    "Tokyo Ghoul √A",
    "Mahouka Koukou no Rettousei",
    "Boku wa Tomodachi ga Sukunai NEXT",
    "Joker Game",
    "Avatar: The Last Airbender",
    "Charlotte"
]

It's just a bunch of values and no key for me to construct my model object. This is how I would plan to do it

struct AllNames {
    
    let name: String   
}

But there's no key name for me to access. How would you go about accessing this data to print each name to the console in Swift?

您的JSON是一系列字符串，因此没有模型，您只需要

do {
    let arr = try JSONDecoder().decode([String].self, from: jsonData)
    print(arr)
 }
 catch {
    print(error)
 }

Your json is an array of strings , so no model is here and you only need

do {
    let arr = try JSONDecoder().decode([String].self, from: jsonData)
    print(arr)
 }
 catch {
    print(error)
 }

将JSON字符串转换为数组：

    func getArrayFromJSONString(jsonStr: String) -> Array<Any> {
        
        let jsonData: Data = jsonStr.data(using: .utf8)!
     
        let arr = try? JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers)
        
        if arr != nil {
            return arr as! Array<Any>
        }
        
        return []
    }

测试案例：

    let jsonStr = """
    [
        \"Hyouka\",
        \"Youjo Senki\",
        \"Bungou Stray Dogs 2nd Season\",
        \"Fullmetal Alchemist: Brotherhood\",
        \"Tokyo Ghoul √A\",
        \"Mahouka Koukou no Rettousei\",
        \"Boku wa Tomodachi ga Sukunai NEXT\",
        \"Joker Game\",
        \"Avatar: The Last Airbender\",
        \"Charlotte\"
    ]
    """
    
    let arr = getArrayFromJSONString(jsonStr: jsonStr)
    
    print(arr)

打印日志：

[Hyouka, Youjo Senki, Bungou Stray Dogs 2nd Season, Fullmetal Alchemist: Brotherhood, Tokyo Ghoul √A, Mahouka Koukou no Rettousei, Boku wa Tomodachi ga Sukunai NEXT, Joker Game, Avatar: The Last Airbender, Charlotte]

Convert JSON string to array:

    func getArrayFromJSONString(jsonStr: String) -> Array<Any> {
        
        let jsonData: Data = jsonStr.data(using: .utf8)!
     
        let arr = try? JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers)
        
        if arr != nil {
            return arr as! Array<Any>
        }
        
        return []
    }

Test case:

    let jsonStr = """
    [
        \"Hyouka\",
        \"Youjo Senki\",
        \"Bungou Stray Dogs 2nd Season\",
        \"Fullmetal Alchemist: Brotherhood\",
        \"Tokyo Ghoul √A\",
        \"Mahouka Koukou no Rettousei\",
        \"Boku wa Tomodachi ga Sukunai NEXT\",
        \"Joker Game\",
        \"Avatar: The Last Airbender\",
        \"Charlotte\"
    ]
    """
    
    let arr = getArrayFromJSONString(jsonStr: jsonStr)
    
    print(arr)

Print log:

[Hyouka, Youjo Senki, Bungou Stray Dogs 2nd Season, Fullmetal Alchemist: Brotherhood, Tokyo Ghoul √A, Mahouka Koukou no Rettousei, Boku wa Tomodachi ga Sukunai NEXT, Joker Game, Avatar: The Last Airbender, Charlotte]
