swift php json解析,JSON解析swift 4

我试图解析一些JSON数据,但遇到了一些问题。这是JSON:

{

"result": {

"artist": {

"name": "The Beatles"

},

"track": {

"name": "Yesterday",

"text": "[Verse 1]\nYesterday\nAll my troubles seemed so far away\nNow it looks as though they're here to stay\nOh, I believe in yesterday\n\n[Verse 2]\nSuddenly\nI'm not half the man I used to be\nThere's a shadow hanging over me\nOh, yesterday came suddenly\n\n[Chorus]\nWhy she had to go\nI don't know, she wouldn't say\nI said something wrong\nNow I long for yesterday\n\n[Verse 3]\nYesterday\nLove was such an easy game to play\nNow I need a place to hide away\nOh, I believe in yesterday\n\n[Chorus]\nWhy she had to go\nI don't know, she wouldn't say\nI said something wrong\nNow I long for yesterday\n\n[Verse 4]\nYesterday\nLove was such an easy game to play\nNow I need a place to hide away\nOh, I believe in yesterday",

"lang": {

"code": "en",

"name": "English"

}

},

"copyright": {

"notice": "Yesterday lyrics are property and copyright of their owners. Commercial use is not allowed.",

"artist": "Copyright The Beatles",

"text": "All lyrics provided for educational purposes and personal use only."

},

"probability": "75.00",

"similarity": 1

}

}

到目前为止,我的代码是:

guard let url = URL(string: "https://orion.apiseeds.com/api/music/lyric/Beatles\Yesterday?apikey=xxx") else { return }

URLSession.shared.dataTask(with: url) { (data, response, error) in

if error != nil {

print(error!)

}

guard let data = data else { return }

do {

let data = try JSONDecoder().decode(Result.self, from: data)

print(data)

} catch let jsonError {

print(jsonError)

}

}.resume()

struct Result: Codable {

let artist: [Artist]

}

struct Artist: Codable {

let name: String

}

当我尝试运行它时得到的错误是:

keynotfound(编码键(stringvalue:“artist”,intvalue:nil),

swift.decodingError.context(编码路径:[],debugDescription:“否”

与键编码键关联的值(StringValue:\“artist\”,

intvalue:nil)(“艺术家\”)“,underlyingError:nil)

我只想从歌曲中得到歌词。

请有人看看这个,因为我正在努力很多。
