通过 data.nba.net 访问 API 时遇到问题

Question

我将 URL 保存在 info.plist 中，如下所示： BASE_URL 字符串 $(BASE_URL)

在我的项目的构建设置中，我添加了一个用户定义的设置，如下所示： BASE_URL http://data.nba.net

设置后，当我尝试将网站放入 url 变量时，该变量返回“”。在调试问题时，我看不到存储在该变量下的网站。

我是 Swift 的新手，还在学习，所以我设置结构的过程中的任何 cmets 都会受到赞赏。

import UIKit

struct sports_content: Decodable {
    let sports_meta_expanded: sports_meta
    let teams_expanded: teams
}

struct sports_meta: Decodable {
    let date_time: String?
    let season_meta_list: season_meta
}

struct season_meta: Decodable {
    let calendar_date: Date
    let season_year: Int?
    let stats_season_year: Int?
    let stats_season_id: Int?
    let stats_season_stage: Int?
    let roster_season_year: Int?
    let schedule_season_year: Int?
    let standings_season_year: Int?
    let season_id: Int?
    let display_year: String
    let display_season: String
    let season_stage: Int?
}

struct next: Decodable {
    let url: String
}

struct teams: Decodable {
    let season_year: year
    let team_data: [team]
}

struct year: Decodable {
    let season_year: Int?
}

struct team: Decodable {
    let is_nba_team: Bool
    let team_name: String
    let team_nickname: String
    let team_code: String
    let team_abbrev: String
    let city: String
    let state: String
    let team_short_name: String
    let team_id: Int?
    let conference: String
    let division_id: String
}

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        let url = Bundle.main.infoDictionary?["BASE_URL"] as? String ?? ""

        guard let convertedURL = URL(string: url) else {
            return
        }

        URLSession.shared.dataTask(with: convertedURL) { (data, response, error) in
        guard let data = data else {
            return
        }
        do{
            let dataSet = try JSONDecoder().decode(sports_content.self, from: data)
            print(dataSet)
        } catch {
            print("JSONSerialization error:", error)
        }
        }.resume()
    }


}

构建设置在构建/编译时使用，不一定在运行时使用。

要将您的 URL 放入 infoDictionary，您需要将其添加到 Info.plist 文件中。双击 Info.plist 以在 Xcode 中打开视图，然后单击 Editor 菜单下的“Add Value”，然后您可以添加 BASE_URL 作为键和您的 URL 作为值。

尝试使用 $(BASE_URL) 作为 Info.plist 中的值，看看是否在构建时添加了构建设置。 :)
