ios - 使用 youtube api 通过 swift 3 获取视频列表

Question

我想取回 channel 视频的标题和 ID，但我在 JSON 级别进行了阻止。它的效果是，当我尝试制作 MYJSONARRAY ["items"] [0] 时，没有任何显示:/感谢您的帮助:)

let url = URL(string: "https://www.googleapis.com/youtube/v3/search?key=**************Q&channelId=UCFNHx0ppCqm4EgPzEcOc29Q&part=snippet,id&order=date&maxResults=50")
    let task = URLSession.shared.dataTask(with: url!) { (data, reponse, error) in

        if error != nil {
            print("ERROR")
        }else{
            if let content = data {
                do{
                    let myJsonArray = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
                    print(myJsonArray["items"][0]) //NOT WORKING
                    //let test1 = myJsonArray["items"]
                    //print(myJsonArray)
                    print("\n \n --------------------- \n \n")
                    if let items = myJsonArray["items"] as? NSDictionary{
                        print(items) // NOT WORKING
                    }

                }catch{

                }
            }
        }

    }
    task.resume()

您没有正确转换，AnyObject 不适合转换为 JSON 响应，它通常是一个字典项数组。

改变这一行..

let myJsonArray = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject

到

if let myJsonArray = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as? [String:Any] {

//Now it's working

   if let items = myJsonArray["items"] as? [[String:Any]] {
       for item in items {
           print(item)
       }  
   }
}
