【问题描述】：
我正在使用共享的 WordPress 服务器。我让他们安装 PHP OAuth 2.0 扩展，他们回答说，从 PHP 7 开始，这是其核心的一部分。
然而，由于某种原因，当我尝试我的代码连接到 beatport.com 的 AOuth 时，我收到以下错误：
致命错误：未捕获的错误：在中找不到类“OAuth” /var/sites/t/trancemusicevents.com/public_html/beatportapi/beatport_api.php:80 堆栈跟踪：#0 {main} 抛出 /var/sites/t/trancemusicevents.com/public_html/beatportapi/beatport_api.php 80号线
这是它引用的代码：

它取自 GitHub 上的开发人员。我不是编码专家，所以我不确定是我的代码造成了问题，还是因为我的服务器上没有安装 OAuth PHP 扩展，即使它应该安装。我的代码有什么错误，或者我的服务器上没有安装 OAuth PHP 扩展？
【问题讨论】：
-
OAuth类是PECL OAuth >= 0.99.1的一部分，因此它是一个PECL 模块。 php.net/OAuth -
所以 PECL OAuth 需要安装在我的服务器上？
-
是的，OAuth 不是当前任何 PHP 核心的一部分。
-
嗯很有趣，因为我的托管服务提供商一直说这是出于某种原因。感谢您的回复
-
那么他应该看看 PHP 手册页。它清楚地表明它是一个 PECL 模块。
