【问题描述】：
我正在尝试将数据从 API 映射到我的自定义类，但我在控制台中收到此错误“typeMismatch(Swift.Array, Swift.DecodingError.Context(codingPath: [], debugDescription: "Expected解码数组，但找到了字典。”，基础错误：无）。不知道为什么它在那里显示这个数组；我该如何解决这个问题。错误
struct News: Codable {
var status: String?
var totalResults: Int?
var articles: [Article]?
enum CodingKeys: String, CodingKey {
case status = "status"
case totalResults = "totalResults"
case articles = "articles"
}
}
// MARK: - Article
struct Article: Codable {
var source: Source?
var author: String?
var title: String?
var articleDescription: String?
var url: String?
var urlToImage: String?
var publishedAt: String?
var content: String?
enum CodingKeys: String, CodingKey {
case source = "source"
case author = "author"
case title = "title"
case articleDescription = "description"
case url = "url"
case urlToImage = "urlToImage"
case publishedAt = "publishedAt"
case content = "content"
}
}
func getAllCountryNameFrom() {
AF.request(self.baseURL + self.apiKeyPathCompononent, method: .get, parameters: nil, encoding: URLEncoding.default, headers: nil, interceptor: nil).response { (responseData) in
guard let data = responseData.data else {return}
do {
let news = try self.jsonDecoder.decode(News.self, from: data)
print(news)
} catch {
print(error)
}
}
}

将您的
data附加为.utf8字符串。
