Soundcloud API、PHP 和 OAuth

发布于 2024-08-29 23:30:37 字数 639 浏览 10 评论 0原文

我正在构建一个网站，我需要从我的 soundcloud 帐户查询我的最后两个曲目并将它们显示在我的页面上。我已经阅读了 Soundcloud API 文档，但它似乎晦涩难懂并且远远超出了我的能力范围。我已经安装了用于使用 API 和 Oauth 的 PHP 库，并设置了 SoundCloud 应用程序来获取消费者密钥，但我无法启动 OAuth 会话。

我正在使用这个库。

我需要从我的 Soundcloud 帐户中检索最后 2 首曲目。在我需要库中的文件（soundcloud.php 和 oauth.php）后，我需要设置四个参数：$consumer_key、$consumer_secret、$callback_url、$tmp_path。

我已经有了我的密钥和可写缓存文件夹。我不知道我的回调网址是什么。另外，我必须说我找不到任何工作示例代码，所以我什至无法开始编写任何内容。就这样被堵住了！

有没有办法在不调用另一个窗口的情况下自动化 OAuth 过程，以便在我的 PHP 脚本中请求我的 OAuth 令牌？

我想知道您是否可以给我一些示例代码来执行此操作。那太好了！

这可能对你有用。登录后，它将我最喜欢的曲目嵌入到页面中。
您可以更改 $favs 来加载您自己的歌曲而不是您最喜欢的歌曲。

另请注意，我的 config.php 包括我的consumer_key、consumer_secret 和我的callback_url。

$callback_url = 'http://localhost/soundcloud';

您希望它等于您的 php 脚本所在的位置。

<?php
  require_once ('php-soundcloud/mptre-php-soundcloud-644bb0e/oauth.php');
  require_once ('php-soundcloud/mptre-php-soundcloud-644bb0e/soundcloud.php');
  require_once ('config.php');

session_start();

// Clear the session i.e delete all stored tokens.
if (isset($_GET['logout'])) {
    session_destroy();
}

// Variables used for verifying the status of the "OAuth dance".
$oauth_token = (isset($_GET['oauth_verifier']))
    ? $_GET['oauth_verifier']
    : ((isset($_SESSION['oauth_access_token'])) ? $_SESSION['oauth_access_token'] : NULL);
$oauth_request_token = (isset($_SESSION['oauth_request_token']))
    ? $_SESSION['oauth_request_token']
    : NULL;
$oauth_request_token_secret = (isset($_SESSION['oauth_request_token_secret']))
    ? $_SESSION['oauth_request_token_secret']
    : NULL;

if (isset($oauth_token) && isset($oauth_request_token) && isset($oauth_request_token_secret)) {
    // Retreive access tokens if missing.
    if (!isset($_SESSION['oauth_access_token']) && !isset($_SESSION['oauth_access_token_secret'])) {
        $soundcloud = new Soundcloud(
            $consumer_key,
            $consumer_secret,
            $_SESSION['oauth_request_token'],
            $_SESSION['oauth_request_token_secret']
        );
        $token = $soundcloud->get_access_token($oauth_token);
        $_SESSION['oauth_access_token'] = $token['oauth_token'];
        $_SESSION['oauth_access_token_secret'] = $token['oauth_token_secret'];
    }

    // Construct a fully authicated connection with SoundCloud.
    $soundcloud = new Soundcloud(
        $consumer_key,
        $consumer_secret,
        $_SESSION['oauth_access_token'],
        $_SESSION['oauth_access_token_secret']
    );

    // Get basic info about the authicated visitor.
    $me = $soundcloud->request('me');
    $me = new SimpleXMLElement($me);
    $me = get_object_vars($me);

    // Get some embedding code for favs
    $favs = $soundcloud->request('http://api.soundcloud.com/users/'.$me['id'].'/favorites/');
    $favs = new SimpleXMLElement($favs);

} else {
    // This is the first step in the "OAuth dance" where we ask the visitior to authicate himself.
    $soundcloud = new Soundcloud($consumer_key, $consumer_secret);
    $token = $soundcloud->get_request_token($callback_url);

    $_SESSION['oauth_request_token'] = $token['oauth_token'];
    $_SESSION['oauth_request_token_secret'] = $token['oauth_token_secret'];

    $login = $soundcloud->get_authorize_url($token['oauth_token']);
}
?>

另请注意，我是一名 php 菜鸟，第一次使用此 api...所以我的能力暂时无法超越此范围。其中大部分是从您正在使用的 php 包装库附带的演示中“借用”的。

希望它有帮助:)

ps。不确定是否有一种方法可以在不调用另一个窗口的情况下自动化 OAuth 过程。

This may be useful to you. After logging in, it embeds my favourite tracks into the page.
You could change $favs to loads your own songs instead of your favourites instead.

Also note, my config.php includes my consumer_key, consumer_secret and my callback_url.

$callback_url = 'http://localhost/soundcloud';

You want it to equal the place where your php script is.

        </div>
    </div>
</body>
</html>

Also note, that I'm a php noob, using this api for the first time... so my abilities don't stretch past this for the moment. Most of this was "borrowed" from the demo that comes with the php wrapper library you're using.

Hope it helps though :)

ps. Not sure if there is a way to automatize the OAuth process without invoking another window yet.
