将麻烦的JSON字符串转换为Swift中的对象

我有一个无法转换为JSON的字符串。在搜索的前几页中，我尝试了JSONDecode、JSONSerialization和所有其他建议。我还试着把它解码成可编码的结构

我认为数据中包含换行符（“\r\n”）这一事实可能会有问题，所以我也尝试删除这些换行符，并删除空白（有很多，我想让一些讨厌的、不可打印的东西不在其中）。绳子在这里，它很长

var rawData: String = "{\r\n    \"contacts\": [\r\n        {\r\n                \"id\": \"c200\",\r\n                \"name\": \"Ravi Tamada\",\r\n                \"email\": \"ravi@gmail.com\",\r\n                \"address\": \"xx-xx-xxxx,x -

字符串只是来自的演示数据

---

任何想法、想法或工作样本都会很好。我知道这是一个听起来很常见的问题，但尝试了几乎所有方法后，我仍然无法让它正常工作。

JSONDecoder

不关心空格或换行符，只要它是格式良好的JSON。想一想你的模型应该是什么样子，而不是担心新行字符

通过快速查看JSON，我创建了以下模型结构：

struct Phone : Codable {
    let mobile: String
    let home: String
    let office: String
}

struct Contact : Codable {
    let id: String
    let name: String
    let email: String
    let address: String
    let gender: String
    let phone: Phone
}

struct Contacts : Codable {
    let contacts: [Contact]
}

您只需解码一个

联系人

对象，如下所示：

let json = try! Data.init(contentsOf: URL(string: "https://api.androidhive.info/contacts/")!)
let decoder = JSONDecoder()
let contacts = try! decoder.decode(Contacts.self, from: json)

无法解码的一个可能原因可能是复制JSON字符串并使其成为单行时出错。正如您在这里看到的，我使用

Data.init（contentsOf:）

来获取数据。这比自己复制和粘贴字符串要可靠得多

还请注意，Swift中有多行字符串文字：

let jsonString = """
your multiline JSON can go here...
"""

我不明白，做

让rawDataData=rawData.data（使用：.utf8）；让json=试试？JSONSerialization.jsonObject（带有：rawDataData！，选项：[]）

对我来说很有用（有一本字典）。那么你目前的问题是什么？最后你想要什么？你能展示一下你的结构/最终对象吗？这很有效。对不起，这个愚蠢的问题，我以前试过这个方法，结果是零。我一定是打错了。如果你将此作为答复，我将接受。非常感谢。如果这起作用，Codable也应该如此。关于JSON序列化有很多问题，所以请找到一个重复的问题，并将其标记为相同的问题，或者删除它，因为问题太多，您可能已经输入了错误。注释中的答案是有效的，但这就是我想这样做的，当我尝试时，由于一些奇怪的原因，它不起作用。我确实把绳子做成了一行。很好的建议。
