我正在尝试使用API v3将视频上传到Youtube。
我正在使用服务帐户方案(https://developers.google.com/accounts/docs/OAuth2?hl=es&csw=1#scenarios),我解决了google-api-php-client库中的一些问题(要阅读p12文件并避免使用isAccessTokenExpired总是返回false)。
<?php
/** Config */
$private_key_password = 'notasecret';
$private_key_file = 'xxxxxxxx-privatekey.p12';
$applicationName = 'xxxxx-youtube';
$client_secret = 'CLIENT_SECRET';
$client_id = 'xxxxxxxxxxxxx.apps.googleusercontent.com';
$service_mail = 'xxxxxxxxxxx@developer.gserviceaccount.com';
$public_key = 'xxxxxxxxxxx';
/** Constants */
$scope = 'https://www.googleapis.com/auth/youtube';
$url_youtube_token = 'https://accounts.google.com/o/oauth2/token';
/** Create and sign JWT */
$jwt = new Google_AssertionCredentials($service_mail, $scope, $private_key_file, $private_key_password, $url_youtube_token);
$jwt_assertion = $jwt->generateAssertion();
/** Use JWT to request token */
$data = array(
'grant_type' => 'urn:ietf:params:oauth:grant-type:jwt-bearer',
'assertion' => $jwt_assertion,
);
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url_youtube_token, false, $context);
此时我在json响应中获得了访问令牌,如下所示:
{
"access_token" : "1/8xbJqaOZXSUZbHLl5EOtu1pxz3fmmetKx9W8CV4t79M",
"token_type" : "Bearer",
"expires_in" : 3600
}
没有“created”,“refresh_token”和“id_token”字段。所以我修复了 Google_OAuth2 类中的 setAccessToken 方法,如果没有设置,则将“created”字段设置为time()。否则 isAccessTokenExpired 总是返回false。
现在,让我们去上传文件。
try{
// Client init
$client = new Google_Client();
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setApplicationName($applicationName);
$client->setAccessToken($result);
if ($client->getAccessToken()) {
if($client->isAccessTokenExpired()) {
// @TODO Log error
echo 'Access Token Expired!!<br/>'; // Debug
}
$youtube = new Google_YoutubeService($client);
$videoPath = "./test.mp4";
// Create a snipet with title, description, tags and category id
$snippet = new Google_VideoSnippet();
$snippet->setTitle("fmgonzalez test " . time());
$snippet->setDescription("fmgonzalez test " . time() );
$snippet->setTags(array("tag1", "tag2"));
// Numeric video category. See
// https://developers.google.com/youtube/v3/docs/videoCategories/list
$snippet->setCategoryId("22");
// Create a video status with privacy status. Options are "public", "private" and "unlisted".
$status = new Google_VideoStatus();
$status->privacyStatus = "public";
// Create a YouTube video with snippet and status
$video = new Google_Video();
$video->setSnippet($snippet);
$video->setStatus($status);
// Size of each chunk of data in bytes. Setting it higher leads faster upload (less chunks,
// for reliable connections). Setting it lower leads better recovery (fine-grained chunks)
$chunkSizeBytes = 1 * 1024 * 1024;
// Create a MediaFileUpload with resumable uploads
$media = new Google_MediaFileUpload('video/*', null, true, $chunkSizeBytes);
$media->setFileSize(filesize($videoPath));
// Create a video insert request
$insertResponse = $youtube->videos->insert("status,snippet", $video,
array('mediaUpload' => $media));
$uploadStatus = false;
// Read file and upload chunk by chunk
$handle = fopen($videoPath, "rb");
$cont = 1;
while (!$uploadStatus && !feof($handle)) {
$chunk = fread($handle, $chunkSizeBytes);
$uploadStatus = $media->nextChunk($insertResponse, $chunk);
echo 'Chunk ' . $cont . ' uploaded <br/>';
$cont++;
}
fclose($handle);
echo '<br/>OK<br/>';
}else{
// @TODO Log error
echo 'Problems creating the client';
}
} catch(Google_ServiceException $e) {
print "Caught Google service Exception ".$e->getCode(). " message is ".$e->getMessage(). " <br>";
print "Stack trace is ".$e->getTraceAsString();
}catch (Exception $e) {
echo $e->getMessage();
}
但我收到“无法启动可恢复上传”消息。
调试, Google_MediaFileUpload 中的方法 getResumeUri 我有这个回应主体:
"error": {
"errors": [
{
"domain": "youtube.header",
"reason": "youtubeSignupRequired",
"message": "Unauthorized",
"locationType": "header",
"location": "Authorization"
}
],
"code": 401,
"message": "Unauthorized"
}
我找到了有关其他方案的示例,但没有找到关于此方案的示例。
如何最终上传视频文件?关于这种情况的任何例子?
提前致谢。

它可能看起来微不足道,但您是否在要将视频上传到的帐户中创建了至少一个频道。对于acceess_token我使用了几乎相同的解决方法然后遇到了同样的问题,直到我进入我的Youtube帐户上传部分并看到该消息在上传视频之前创建了至少一个频道。希望它有所帮助。

您获得的错误回复是设计使然。 Google不允许通过服务帐户访问Youtube API。
服务帐户不适用于YouTube Data API调用,因为 服务帐户需要关联的YouTube频道,而您却不能 将新的或现有的渠道与服务帐户相关联。 如果您使用的话 服务帐户调用YouTube Data API,API服务器返回 错误类型设置为未授权并设置原因的错误 的 youtubeSignupRequired 即可。
