使用 Zend GData Picasa API 更新 Picasa 视频缩略图

发布于 2024-10-05 10:06:56 字数 1416 浏览 3 评论 0原文

我想使用 API 更新 picasa 网络相册中视频的缩略图。 我有 照片 PHP 示例代码 用于运行照片数据 API。

文档称我可以“提供您自己的视频缩略图”通过更新照片。

我尝试过以下功能,但没有任何反应。请帮忙!

/**
 * Updates photo (for changing video thumbs
 *
 * @param  Zend_Http_Client $client  The authenticated client
 * @param  string           $user    The user's account name
 * @param  integer          $albumId The album's id
 * @param  integer          $photoId The photo's id
 * @param  array            $photo   The uploaded photo
 * @return void
 */
function updatePhoto($client, $user, $albumId, $photoId, $photo)
{
        $photos = new Zend_Gdata_Photos($client);

        $photoQuery = new Zend_Gdata_Photos_PhotoQuery;
        $photoQuery->setUser($user);
        $photoQuery->setAlbumId($albumId);
        $photoQuery->setPhotoId($photoId);
        $photoQuery->setType('entry');

        $entry = $photos->getPhotoEntry($photoQuery);

        $fd = $photos->newMediaFileSource($photo["tmp_name"]);
        $fd->setContentType($photo["type"]);
        $entry->setMediaSource($fd);

        $entry->save();

        outputPhotoFeed($client, $user, $albumId, $photoId);        
}

I want to update the thumbnail of my video in picasa web albums using the API.
I've got the Photos PHP sample code for the Photos data API running.

The documentation says that I can "Provide your own video thumbnail" by updating the photo.

I've tried the following function but nothing happens. Please help!

/**
 * Updates photo (for changing video thumbs
 *
 * @param  Zend_Http_Client $client  The authenticated client
 * @param  string           $user    The user's account name
 * @param  integer          $albumId The album's id
 * @param  integer          $photoId The photo's id
 * @param  array            $photo   The uploaded photo
 * @return void
 */
function updatePhoto($client, $user, $albumId, $photoId, $photo)
{
        $photos = new Zend_Gdata_Photos($client);

        $photoQuery = new Zend_Gdata_Photos_PhotoQuery;
        $photoQuery->setUser($user);
        $photoQuery->setAlbumId($albumId);
        $photoQuery->setPhotoId($photoId);
        $photoQuery->setType('entry');

        $entry = $photos->getPhotoEntry($photoQuery);

        $fd = $photos->newMediaFileSource($photo["tmp_name"]);
        $fd->setContentType($photo["type"]);
        $entry->setMediaSource($fd);

        $entry->save();

        outputPhotoFeed($client, $user, $albumId, $photoId);        
}

我几乎是对的,更新后的代码可以工作...

    /**
     * Updates photo (for changing video thumbs
     *
     * @param  Zend_Http_Client $client  The authenticated client
     * @param  string           $user    The user's account name
     * @param  integer          $albumId The album's id
     * @param  integer          $photoId The photo's id
     * @param  array            $photo   The uploaded photo
     * @return void
     */
    function updatePhoto($client, $user, $albumId, $photoId, $photo)
    {
            $photos = new Zend_Gdata_Photos($client);

            $photoQuery = new Zend_Gdata_Photos_PhotoQuery;
            $photoQuery->setUser($user);
            $photoQuery->setAlbumId($albumId);
            $photoQuery->setPhotoId($photoId);
            $photoQuery->setType('entry');

            $entry = $photos->getPhotoEntry($photoQuery);
            $uri = $entry->getLink("edit-media")->href;             

            $fd = $photos->newMediaFileSource($photo["tmp_name"]);
            $fd->setContentType($photo["type"]);
            $entry->setMediaSource($fd);

        $result = $entry->save($uri);
            if ($result) {
                outputPhotoFeed($client, $user, $albumId, $photoId);        
            } else {
                echo "There was an issue with upating this photo.";
            }
    }

i was nearly right, updated code that works...

    /**

     * @param  array            $photo   The uploaded photo
     * @return void
     */
    function updatePhoto($client, $user, $albumId, $photoId, $photo)
    {
            $photos = new Zend_Gdata_Photos($client);

            $photoQuery = new Zend_Gdata_Photos_PhotoQuery;
            $photoQuery->setUser($user);
            $photoQuery->setAlbumId($albumId);
            $photoQuery->setPhotoId($photoId);
            $photoQuery->setType('entry');

            $entry = $photos->getPhotoEntry($photoQuery);
            $uri = $entry->getLink("edit-media")->href;             

            $fd = $photos->newMediaFileSource($photo["tmp_name"]);
            $fd->setContentType($photo["type"]);
            $entry->setMediaSource($fd);

        $result = $entry->save($uri);
            if ($result) {
                outputPhotoFeed($client, $user, $albumId, $photoId);        
            } else {
                echo "There was an issue with upating this photo.";
            }
    }
