Youtube API V3 PHP按关键字搜索代码示例不起作用

Youtube API V3 PHP按关键字搜索代码示例不起作用,php,youtube,youtube-api,Php,Youtube,Youtube Api,我试着运行Google在开发人员代码示例页()上提供给您的示例代码,但对我不起作用。我确保从GitHub下载了该库的最新版本,将其安装到我的PHP5/Apache2服务器上,更改了包含路径,并且由于某些原因,其中一个require_once项无法正常工作。下面是我已经修改过的代码(仅使用一些echo语句进行了修改)。我输入了我的开发者密钥,但出于明显的原因,我在这篇文章中删除了它 <?php $htmlBody = <<<END <form method="GET"

有趣的部分就在这里

    require_once ('Google/Service/YouTube.php');
    echo "echo 3";
    echo "<br/>";
第二个require_once语句导致页面在此之后停止运行,这是怎么回事?有一次,我在set_include_path()后面紧跟着一个echo语句,但它似乎工作正常,所以我删除了它

我通过手动添加所有依赖项解决了这个问题。在添加了所有必需的依赖项之后,这就是我最终得到的结果

require_once ('Google/Logger/Null.php');
require_once('Google/Client.php');
require_once ('Google/Config.php');
require_once ('Google/Model.php');
require_once ('Google/Collection.php');
require_once ('Google/Service.php');
require_once ('Google/Service/Resource.php');
require_once ('Google/Service/YouTube.php');

有些事情你可以试试:

  • 打开PHP的错误输出。如果发生错误,您将在生成的html中获得信息。您可以在中找到有关如何启用它的更多信息

  • 确保
    Google/Service/YouTube.php
    存在。导航到该文件夹并手动检查

  • 在包含
    YouTube.php
    之前先打印包含路径(我认为这可能不是问题,但谁知道…)


看起来您没有正确设置PHP的包含路径。如果您将此客户端库的src/文件添加到include路径中,它应该可以正常工作。

您可以添加

require_once 'include/Google/autoload.php';
在代码前面,删除所有其他要求,如:

//require_once 'include/Google/Client.php'; 
//require_once 'include/Google/Service/YouTube.php';

但是php版本应该大于5.3

检查错误日志。文件可能没有显示错误报告,我得到以下错误<代码>致命错误:在第32行的/home/pi/Google-api-php-client/src/Google/Service/YouTube.php中找不到类“Google\u-Service”,听起来好像缺少一些依赖项。我不这么认为,但是您对库源代码做了任何更改吗?我添加了
require_once('Google/Service.php')
错误更改为
致命错误:在第1332行的/home/pi/Google-api-php-client/src/Google/Service/YouTube.php中找不到类“Google\u-Service\u-Resource”
当我不断添加依赖项时,更多的内容会丢失。我是否缺少自动加载所需内容的内容,或者我必须继续手动搜索?我只是下载了库来重现问题,我也得到了它。要么我们俩都很傻,要么谷歌的代码中有一些奇怪的错误。
//require_once 'include/Google/Client.php'; 
//require_once 'include/Google/Service/YouTube.php';
