我如何使用 swift3 解析这个 JSON 数据。我正在尝试将其转换为 [String: Any] 字典。

我正在使用 JSONSerialization 来解析此数据，但无法正确解析。这些数据有嵌套的字典，我该如何解析？谁能帮我解决这个问题？

很难从您在评论中发布的内容中辨别出来，但这里用于解析 imdb_id：

super.httpRequest(params: requestDict) { (responseData) in 
    guard let data = responseData else { return } 
    do { 
         let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] 

           if let info = json["info"] as? [String: Any] {
                let id = info["imdb_id"] as? String 
                print("The imdb_id is \(id)")
           }
       } catch let error as NSError { 
              print(error) 
    } 
}

你看到打印出来的是什么？
