Swift 4可解码的json数组

坚吉子

所以我目前正在唤醒一个程序，以解析链接在底部的JSON Api

运行代码时，我得到一些输出，但不是全部控制台输出的图像

主要用于可选类型的Anime，这很好，因为它表明它可以工作，但我也想访问名称，发行日期和语言，但是我不知道如何在Swift 4中使用像这样的JSON数组。我将附加我的当前代码如下。

import UIKit

struct AnimeJsonStuff: Decodable {
    let data: [AnimeDataArray]
}

struct AnimeDataArray: Decodable {
    let type: String?
}

class OsuHomeController: UICollectionViewController, UICollectionViewDelegateFlowLayout {
    func jsonDecoding() {
        let jsonUrlString = "https://kitsu.io/api/edge/anime"

        guard let url = URL(string: jsonUrlString) else {return} //
        URLSession.shared.dataTask(with: url) { (data, response, err) in

            guard let data = data else {return}

            do {
                let animeJsonStuff =  try JSONDecoder().decode(AnimeJsonStuff.self, from: data)
                print(animeJsonStuff.data)

                let animeDataArray = try JSONDecoder().decode(AnimeDataArray.self, from: data)
                print(animeDataArray.type as Any)
            } catch let jsonErr {
                print("Error serializing json", jsonErr)
            }
        }.resume()
    }
}

在那之后，我还有更多代码，但这仅用于设置自定义collectionViewCells。

这也是指向api的链接

请在下面检查：

我没有为所有键添加。我在中添加了一些attributes。

struct AnimeJsonStuff: Decodable {
    let data: [AnimeDataArray]
}

struct AnimeLinks: Codable {
    var selfStr   : String?

    private enum CodingKeys : String, CodingKey {
        case selfStr     = "self"
    }
}
struct AnimeAttributes: Codable {
    var createdAt   : String?

    private enum CodingKeys : String, CodingKey {
        case createdAt     = "createdAt"
    }
}
struct AnimeRelationships: Codable {
    var links   : AnimeRelationshipsLinks?

    private enum CodingKeys : String, CodingKey {
        case links     = "links"
    }
}

struct AnimeRelationshipsLinks: Codable {
    var selfStr   : String?
    var related   : String?

    private enum CodingKeys : String, CodingKey {
        case selfStr     = "self"
        case related     = "related"
    }
}

struct AnimeDataArray: Codable {
    let id: String?
    let type: String?
    let links: AnimeLinks?
    let attributes: AnimeAttributes?
    let relationships: [String: AnimeRelationships]?

    private enum CodingKeys: String, CodingKey {
        case id = "id"
        case type = "type"
        case links = "links"
        case attributes = "attributes"
        case relationships = "relationships"
    }
}

Json解析：

func jsonDecoding() {
    let jsonUrlString = "https://kitsu.io/api/edge/anime"

    guard let url = URL(string: jsonUrlString) else {return} //
    URLSession.shared.dataTask(with: url) { (data, response, err) in
        guard let data = data else {return}
        do {
            let animeJsonStuff =  try JSONDecoder().decode(AnimeJsonStuff.self, from: data)
            for anime in animeJsonStuff.data {
                print(anime.id)
                print(anime.type)
                print(anime.links?.selfStr)
                print(anime.attributes?.createdAt)
                for (key, value) in anime.relationships! {
                    print(key)
                    print(value.links?.selfStr)
                    print(value.links?.related)
                }
            }
        } catch let jsonErr {
            print("Error serializing json", jsonErr)
        }
    }.resume()
}
