Swift 5 Alamofire字典解析错误

Question

我想在 Swift 5 中用 Alamofire 解析 json 但我没有在下面得到我的代码数组。

我的 json 文件

[{"type":"success","data":[{"id":"1","sectionId":"1","title":"test title","detail":"detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text detail test text ","image":"test.jpg","view":"0","status":"1"}]}]

我的swift5个代码

if let json = response.result.value {
                    print(json)
                         if let dictionaryArray = json as? Dictionary<String, AnyObject?> {
                             print(dictionaryArray)
                             let json = dictionaryArray
                             if let type = json["type"] as? String,
                                let results = json["data"] as? Array<Dictionary<String, AnyObject?>> {
                                print(type)
                            for i in 0..<results.count{
                                    let json = results[i]
                                    if let id = json["id"] as? String, let jokeString = json["title"] as? String{
                                        self.items.append(Item(id: id, sectionId : "0", title: jokeString, detail:"", image: "", view : "0", status : "0"))
                                        print(json)

                                }
                            }
                        }
                    }
                }
        }

有什么想法吗？我哪里做错了？

根是一个数组，所以它 [[String:Any]]

 if let dictionaryArray = json as? [[String:Any]] {

顺便说一下，最好使用 Codable

Alamofire.request(url, method: .get, parameters: [:], encoding: JSONEncoding.default, headers: [:]).responseData { res in
    guard let data = res.data else { return } 

      do {
         let res = try JSONDecoder().decode([Root].self, from:data)
         print(res)
      } 
      catch {
         print(error)
     }
}

struct Root: Codable {
    let type: String
    let data: [Datum]
}

// MARK: - Datum
struct Datum: Codable {
    let id, sectionID, title, detail: String
    let image, view, status: String

    enum CodingKeys: String, CodingKey {
        case id
        case sectionID = "sectionId"
        case title, detail, image, view, status
    }
}

编辑：

if let dictionaryArray = json as? [[String:Any?]] {
    for item in dictionaryArray {
        if let type = item["type"] as? String,let results = item["data"] as?  [[String:Any?]] {
            print(type)
            for json in results {
                 if let id = json["id"] as? String, let jokeString = json["title"] as? String {
                    self.items.append(Item(id: id, sectionId : "0", title: jokeString, detail:"", image: "", view : "0", status : "0"))
                    print(json)
                }
            }
        }
    }
}
