使用Youtube API V3,我可以从用户的活动源中提取视频的缩略图(使用api中的activities列表)。
我想要实现的是,当用户点击视频时,应该播放视频。我看过iframe。然而,api上的活动列表没有显示如何获取视频的URL,但是Videos资源显示了一个不同的播放器,然后我很困惑,如何将它集成到我的代码中。
var activityId, nextPageToken, prevPageToken, videoSnippet;
// Once the api loads call a function to get the uploads playlist id.
function handleAPILoaded() {
requestUserUploadsactivityId();
}
//Retrieve the uploads playlist id.
function requestUserUploadsactivityId() {
// https://developers.google.com/youtube/v3/docs/channels/list
var request = gapi.client.youtube.activities.list({
// mine: '' indicates that we want to retrieve the channel for the authenticated user.
home: 'true',
part: 'snippet'
});
request.execute(function(response) {
//structure of content.details
//https://developers.google.com/youtube/v3/docs/channels#resource
console.log(response);
activityId = response.items[0].id;
requestVideoPlaylist(activityId);
});
}
// Retrieve a playist of videos.
function requestVideoPlaylist(home, pageToken) {
$('#video-container').html('');
var requestOptions = {
home: 'true',
part: 'snippet',
maxResults: 12
};
if (pageToken) {
requestOptions.pageToken = pageToken;
}
var request = gapi.client.youtube.activities.list(requestOptions);
request.execute(function(response) {
var activityItems = response.result.items;
if (activityItems) {
// For each result lets show a thumbnail.
jQuery.each(activityItems, function(index, item) {
createDisplayThumbnail(item.snippet);
});
} else {
$('#video-container').html('Sorry you have no activities on your feed');
}
});
}
// Create a thumbnail for a video snippet.
function createDisplayThumbnail(videoSnippet) {
var titleEl = $('<h4>');
titleEl.addClass('video-title');
$(titleEl).html(videoSnippet.title);
var thumbnailUrl = videoSnippet.thumbnails.default.url;
console.log(videoSnippet);
var div = $('<div>');
div.addClass('video-content');
div.css('backgroundImage', 'url("' + thumbnailUrl + '")');
div.append(titleEl);
$('#video-container').append(div);
}

活动列表包括几种活动类型:
上传,喜欢,评论,评论,播放列表,推荐,公告,社交..
并且只有某种活动与视频相关。然后,当活动类型与视频相关时,您只能从contentDetails中检索videoId。您可以使用videoId显示视频。
https://developers.google.com/youtube/v3/docs/activities
你在“YouTube主题资源管理器”中有一个很好的例子。在此应用程序中,您可以检索社交活动并从此类活动中检索videoId
https://code.google.com/p/yt-topic-explorer/source/browse/app/scripts/controllers/logged-in.js
$scope.social = function() {
$rootScope.topicResults = [];
$rootScope.spinner.spin($('#spinner')[0]);
youtube({
method: 'GET',
service: 'activities',
params: {
part: 'id,snippet,contentDetails',
home: true,
maxResults: constants.YOUTUBE_API_MAX_RESULTS
},
callback: function(response) {
if ('items' in response) {
$scope.videoIds = [];
$scope.personalizedTopics = [];
angular.forEach(response.items, function(activity) {
if ((activity.snippet.type == constants.SOCIAL_TYPE)&&(activity.contentDetails.social.resourceId.videoId)){
$scope.videoIds.push(activity.contentDetails.social.resourceId.videoId);
}
});
}
getTopicsForVideoIds();
}
});
}
您有一个如何显示视频的示例:
https://code.google.com/p/yt-topic-explorer/source/browse/app/scripts/controllers/main.js
function playVideo(container, videoId) {
var width = container.offsetWidth;
var height = container.offsetHeight;
new YT.Player(container, {
videoId: videoId,
width: width,
height: height,
playerVars: {
autoplay: 1,
controls: 2,
modestbranding: 1,
rel: 0,
showInfo: 0
}
});
