Question

我正在使用YouTube API为我的YouTube频道创建应用。我通过以下方式使用Alamofire从播放列表中获取视频：

catch

我一直在寻找，我找不到一个简单的方法来做到这一点。我找到了这样一个答案：How to get number of video views with YouTube API?但是，我正在使用Swift。有没有人有任何想法？

工作解决方案。我使用Decodable而不是原始JSON，但我按照您的代码进行了上一次请求。

let apiKey = "API_KEY"
let playlistId = "PLAYLIST_ID"
let url = URL(string: "https://www.googleapis.com/youtube/v3/playlistItems?playlistId=\(playlistId)&maxResults=25&part=snippet%2CcontentDetails&key=\(apiKey)")!

// Get videos
Alamofire.request(url).responseJSON { (response) in

    guard let JSON = response.result.value,
        let dictionary = JSON as? [String: Any],
        let items = dictionary["items"] as? [AnyObject]
        else { return }

    let videos: [Video] = items.map {
        let videoObj = Video()
        videoObj.videoID = $0.value(forKeyPath: "snippet.resourceId.videoId") as! String
        videoObj.videoTitle = $0.value(forKeyPath: "snippet.title") as! String
        videoObj.videoDescription = $0.value(forKeyPath: "snippet.description") as! String
        videoObj.videoThumbnailUrl = $0.value(forKeyPath: "snippet.thumbnails.default.url") as! String
        return videoObj
    }

    let videoIds = videos.map({ $0.videoID }).joined(separator: ",")
    let statsUrl = URL(string: "https://www.googleapis.com/youtube/v3/videos?part=statistics&id=\(videoIds)&key=\(apiKey)")!

    // Get view count for all videos
    Alamofire.request(statsUrl).responseJSON { (response) in

        guard let JSON = response.result.value,
            let dictionary = JSON as? [String: Any],
            let items = dictionary["items"] as? [AnyObject]
            else { return }

        for i in 0..<items.count {
            let views = items[i].value(forKeyPath: "statistics.viewCount") as! String
            videos[i].viewCount = Int(views)!
        }

        print(videos)
    }
}
