   ("Global_Data"): {
       Created = 574049501;
       Domain = "";
       Expires = "2019-03-19 02:11:40 +0000";
       Name = "Data";
       Path = "/";
       Value = "%7B%22countryISO%22%3A%22US%22%2C%22cultureCode%22%3A%22en-GB%22%2C%22currencyCode%22%3A%22USD%22%2C%22apiVersion%22%3A%222.1.4%22%7D;
       Version = 1;
    }

在从 web 视图中获取 Cookie 数据时，我将 Value => 作为字符串有些字符知道这些字符代表特殊字符或字母。如何将其转换为 JSON 格式。谢谢

"%7B%22countryISO%22%3A%22US%22%2C%22cultureCode%22%3A%22en-GB%22%2C%22currencyCode%22%3A%22USD%22%2C%22apiVersion%22%3A %222.1.4%22%7D"

【解决方案1】：

您的字符串已经是一个 JSON 字符串，您只需从中删除百分比编码，创建一个符合 Decodable 的自定义结构，然后一切就绪：

struct Root: Decodable {
    let countryISO, cultureCode, currencyCode, apiVersion: String
}

let string = "%7B%22countryISO%22%3A%22US%22%2C%22cultureCode%22%3A%22en-GB%22%2C%22currencyCode%22%3A%22USD%22%2C%22apiVersion%22%3A%222.1.4%22%7D"

let json = string.removingPercentEncoding ?? ""

"{"countryISO":"US","cultureCode":"en-GB","currencyCode":"USD","apiVersion":"2.1.4"}"

do {
    let root = try JSONDecoder().decode(Root.self, from: Data(json.utf8))
    print(root.countryISO)    // "US"
    print(root.cultureCode)   // "en-GB"
    print(root.currencyCode)  // "USD"
    print(root.apiVersion)    // "2.1.4"
} catch {
    print(error) 
}
