Linkedin PHP登录API调用

我正在使用Github上的类（Happyr\Linkedin）连接到Linkedin API并创建登录名。它工作得很好，没有任何问题，直到它不再工作，但没有做任何改变

这是我的电话号码：

$linkedIn=new Happyr\LinkedIn\LinkedIn('apikey', 'apisecret');

会话_start（）

我收到的是其中一个供应商包中的异常：

Fatal error: Uncaught Http\Client\Exception\NetworkException: Could not resolve host: www.linkedin.com in /var/www/html/vendor/php-http/curl-client/src/Client.php:134 Stack trace:

您知道如何解决此问题吗？

请更新composer.lock文件，然后重试。

您的网络配置似乎有问题。无论出于何种原因，脚本都无法找到主机

www.linkedin.com

@E_p I从服务器ping linkedin，看起来一切正常。网络配置中可能出现什么错误？唯一的活动是数字海洋水滴关闭了几个小时，由于付款，DO工作人员关闭了它。当液滴关闭时是否会发生影响网络配置的情况？首先，可能是代理和防火墙。您还需要查看php配置，一些功能/模块可以关闭。您还可以尝试将

CURLOPT\u DNS\u USE\u GLOBAL\u CACHE=>false

和

CURLOPT\u DNS\u CACHE\u TIMEOUT=>2

作为curl选项的一部分，这听起来更像是一个注释。
