Question

我想使用PHP访问用户联系人。

我有两个名为index.php＆amp;的文件。在/ var / www / oauth目录中的validate.php。重定向到validate.php后，它现在显示任何内容。它是在“curl init之前”打印echo而不是在“curl init之后”打印echo。请有人帮帮我。

Google帐户设置： -

Client ID:  *********
Email address:  *****
Client secret:  ******
Redirect URIs:  http://localhost/oauth/validate.php
JavaScript origins: http://localhost

这是我的PHP代码。

请检查php_curl扩展程序是否已启用，因此cURL功能将适用于您。

如果已经启用，则发布详细的错误消息，以便我可以在最后检查。
