Question

我正在尝试弄清楚如何在我的iOS应用中使用新的YouTube API（第3版），但我不知道该怎么做。我做了很多关于它的研究，但我发现的是旧API的所有示例和代码，因此它们无效。现在我明白了，为了使用新的API，您必须在Google Developer Console中创建一个项目（我做到了）...但是他们会将您发送到一个包含一些代码的页面，但我真的不明白如何使用它。 link to google api page 我需要知道的是如何从YouTube视频的给定URL中检索一些信息，我需要的信息是“喜欢”的总数和“视图”的总数...使用API 2这很简单它...但现在我真的不知道从哪里开始...... 是否有人可以通过一些示例和一些代码解释如何实现这一目标？我很确定很多人会从中受益。

Answer 1

您不必使用Google提供的iOS客户端来提出这类请求。

导航至API Console并为您的iOS应用程序生成新的Simple API Access密钥。请务必在提供的窗口中输入应用程序的包标识符。或者，您可以创建一个服务器API密钥，以便使用命令行中的基本请求和卷曲进行测试。
根据您的需求查找相关端点。要查找有关视频的信息，您需要使用Videos.list方法。

首先，设置你的URL。我将使用此网址作为示例：https://www.youtube.com/watch?v=AKiiekaEHhI

您将要为part参数指定值。从您的问题来看，您似乎想要传递snippet，contentDetails和statistics值（尽管对于喜欢和观看，您实际上只需要{{ 1}}值）。

然后传入视频的statistics（在这种情况下为id，您最多可以添加50个以逗号分隔的ID）和您的API密钥。您的网址应如下所示：

AKiiekaEHhI

您也可以在API Explorer。

快速实施：

https://www.googleapis.com/youtube/v3/videos?part=contentDetails%2C+snippet%2C+statistics&id=AKiiekaEHhI&key={YOUR_API_KEY}

Objective-C实施：

（此帖子已经过编辑以支持// Set up your URL let youtubeApi = "https://www.googleapis.com/youtube/v3/videos?part=contentDetails%2C+snippet%2C+statistics&id=AKiiekaEHhI&key={YOUR_API_KEY}" let url = NSURL(string: youtubeApi) // Create your request let task = NSURLSession.sharedSession().dataTaskWithURL(url!, completionHandler: { (data, response, error) -> Void in do { if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments) as? [String : AnyObject] { print("Response from YouTube: \(jsonResult)") } } catch { print("json error: \(error)") } }) // Start the request task.resume()。对于使用NSURLSession的实施，请查看修改历史记录）

NSURLConnection

您的日志将如下所示：

// Set up your URL
NSString *youtubeApi = @"https://www.googleapis.com/youtube/v3/videos?part=contentDetails%2C+snippet%2C+statistics&id=AKiiekaEHhI&key={YOUR_API_KEY}";
NSURL *url = [[NSURL alloc] initWithString:youtubeApi];

// Create your request
NSURLRequest *request = [NSURLRequest requestWithURL:url];

// Send the request asynchronously
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *connectionError) {

    // Callback, parse the data and check for errors
    if (data && !connectionError) {
        NSError *jsonError;
        NSDictionary *jsonResult = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&jsonError];

        if (!jsonError) {
            NSLog(@"Response from YouTube: %@", jsonResult);
        }
    }
}] resume];

Response from YouTube: { etag = "\"NO6QTeg0-3ShswIeqLchQ_mzWJs/AAjIATmVK_8ySsAWwEuNfdZdjW4\""; items = ( { contentDetails = { caption = false; definition = hd; dimension = 2d; duration = PT17M30S; licensedContent = 1; }; etag = "\"NO6QTeg0-3ShswIeqLchQ_mzWJs/8v8ee5uPZQa1-ucVdjBdAVXzcZk\""; id = AKiiekaEHhI; kind = "youtube#video"; snippet = { categoryId = 20; channelId = UCkvdZX3SVgfDW8ghtP1L2Ug; channelTitle = "Swordless Link"; description = "Follow me on Twitter! http://twitter.com/swordlesslink\n\nFollow me on TwitchTV for live video game streaming! http://twitch.tv/swordlesslink"; liveBroadcastContent = none; localized = { description = "Follow me on Twitter! http://twitter.com/swordlesslink\n\nFollow me on TwitchTV for live video game streaming! http://twitch.tv/swordlesslink"; title = "The Legend of Zelda: Majora's Mask With Glitches - Part 17: Going Against the Flow"; }; publishedAt = "2015-05-04T10:01:43.000Z"; thumbnails = { default = { height = 90; url = "https://i.ytimg.com/vi/AKiiekaEHhI/default.jpg"; width = 120; }; high = { height = 360; url = "https://i.ytimg.com/vi/AKiiekaEHhI/hqdefault.jpg"; width = 480; }; medium = { height = 180; url = "https://i.ytimg.com/vi/AKiiekaEHhI/mqdefault.jpg"; width = 320; }; standard = { height = 480; url = "https://i.ytimg.com/vi/AKiiekaEHhI/sddefault.jpg"; width = 640; }; }; title = "The Legend of Zelda: Majora's Mask With Glitches - Part 17: Going Against the Flow"; }; statistics = { commentCount = 54; dislikeCount = 3; favoriteCount = 0; likeCount = 265; viewCount = 6356; }; } ); kind = "youtube#videoListResponse"; pageInfo = { resultsPerPage = 1; totalResults = 1; }; } with error: nil键的对象将是您传递给请求的每个视频ID的信息数组。

通过深入了解此响应，您将能够获得所需的信息。例如：

items

将为您提供视频统计信息的字典（您可以在其中获取喜欢的数量和观看次数）。

if let items = jsonResult["items"] as? [AnyObject]? {
    println(items?[0]["statistics"])
}

这种方法可用于直播活动。

    // can use any text

它非常简单易用。您可以在javascript中使用它，npmjs中有一个简单的模块：https://www.npmjs.com/package/youtube-api-es6
