对于我的最新项目,我需要从YouTube搜索的结果作为JSON字符串。我试图从这里修改官方样本的代码,使整个响应数组作为JSON返回,但JSON输出只包括一个结果,只有两个标签的结果
{"etag":""bvxF-DWHx1toJotsdJBeCm43SLs/Ti9GPWl-tTk2fzo_W4M7px11bPY ","eventId":空,"类型":"youtube # searchListResponse"、"nextPageToken":"CBkQAA"、"prevPageToken":空,"visitorId":零}
这就是我的代码:
<?php
header('Cache-Control: no-cache, must-revalidate');
header('Content-type: application/json');
if ($_GET['q'] && $_GET['maxResults']) {
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';
$DEVELOPER_KEY = 'not gonna reveal my key ;) ';
$client = new Google_Client();
$client->setDeveloperKey($DEVELOPER_KEY);
$youtube = new Google_Service_YouTube($client);
try
{
$searchResponse = $youtube->search->listSearch('id,snippet', array(
'q' => $_GET['q'],
'maxResults' => $_GET['maxResults'],
));
print_r(json_encode($searchResponse));
}
catch (Google_ServiceException $e) {
$htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',
htmlspecialchars($e->getMessage()));
}
catch (Google_Exception $e) {
$htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',
htmlspecialchars($e->getMessage()));
}
}
?>
最后我希望有这样的东西

问题是您正在尝试对使用php客户端库时收到的响应对象进行json编码。它不是Youtube API返回的原始JSON对象(以及您想要编码的对象)。
如果是var_dump($searchResponse);
就会看到Google_Service_YouTube_SearchListResponse Object
你想json_encode的"simpleObject",你通过调用toSimpleObject
的模型,如:
json_encode($searchResponse->toSimpleObject());
