如何获取YouTube上“活动”标签下列出的视频？

尝试使用以下内容获取：

Answer 1

要搜索直播活动，您需要将live设置为eventType密钥的值，将video设置为type的值键。

您的请求将如下所示：

HTTP GET: https://www.googleapis.com/youtube/v3/search?eventType=live&part=id%2C+snippet&type=video&key={YOUR_API_KEY}

目标-C：

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

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

// Send the request asynchronously
[NSURLConnection sendAsynchronousRequest:request queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response, NSData *data, 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: %@", jsonResult);
        }
    }
}];

夫特：

// Set up your URL
let youtubeApi: String = "https://www.googleapis.com/youtube/v3/search?eventType=live&part=id%2C+snippet&type=video&key={YOUR_API_KEY}"
var url: NSURL = NSURL(string: youtubeApi)!

// Create your request
var request: NSURLRequest = NSURLRequest(URL: url)
let queue:NSOperationQueue = NSOperationQueue()

// Send the request asynchronously
NSURLConnection.sendAsynchronousRequest(request, queue: queue, completionHandler:{ (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in

    // Callback, parse the data and check for errors
    if data != nil && error == nil {
        var err: NSError?
        if let jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary {
            println("Response: \(jsonResult)")
        }
    } else {
        println("Error: \(error)")
    }
})
