PHP Guzzle 无法解析本地主机上的主机，但可以在服务器上运行

Question

我有这个 Zend 2 应用程序，我正在其中使用 this Azure AD library用于身份验证。几个月来一切都工作正常，但突然它在我的本地主机上停止工作。奇怪的是它在我们的服务器上仍然运行良好。我不认为这是库本身的问题，这就是我在这里寻求帮助的原因。

每当我尝试使用以下代码获取 oauth2 的提供程序时:
(这个Azure类只是League\OAuth2\Client\Provider的扩展)

private static function getAzureProvider(): Azure
{
  $provider = new Azure([
     'clientId' => self::$azure_client_id,
     'clientSecret' => self::$azure_client_secret,
     'redirectUri' => self::$post_login_redirect_uri,
     'tenant' => self::$azure_tenant_id,
     'defaultEndPointVersion' => Azure::ENDPOINT_VERSION_2_0
  ]);
  $baseGraphUri = $provider->getRootMicrosoftGraphUri(null); // <-- This is what triggers the 'Could not resolve' error
  $provider->scope = 'openid profile email offline_access ' . $baseGraphUri . '/User.Read';
  return $provider;
}

我收到以下错误:

Error while obtaining AzureProvider: 'cURL error 6: Could not resolve host: login.microsoftonline.com (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)'.

我已经在网上搜索了一整天，但似乎找不到任何具体的解决方案来解决这个问题。有人知道会发生什么吗？

如果我手动执行curl命令并转到https://login.microsoftonline.com，它似乎工作正常。 我在本地主机和服务器上的 cURL 版本都是 7.64.0，因此两者之间没有区别。如果我应该提供更多信息，请告诉我!

编辑:我的更多源代码如下:

    public static function isLoggedInWithAzure(?string $code = null, ?string $state = null): bool
    {
        return !empty(self::getAzureAccessToken($code, $state);
    }

    public static function doAzureLogin(?string $code = null, ?string $state = null)

        if (!self::isLoggedInWithAzure($code, $state)) {

            }
        } else if (!empty($oauth_session->access_token)) {
            /*
             * Else if access token is set in session, verify if still valid
             */

错误如下:

Could not resolve host: login.microsoftonline.com

正如您所说，应用程序几个月前运行良好，我认为如果您清除 Artisan 中的所有类型的缓存，它也会运行良好。同时运行以下命令，然后再次重新启动服务器。

php artisan route:clear
php artisan config:clear
php artisan cache:clear

尝试更改用于初始化 Azure AAD 的 oauth 提供程序的代码。以下代码片段展示了如何做到这一点。

$provider = new TheNetworg\OAuth2\Client\Provider\Azure([
'clientId' => 'c9e*****9ea',
'clientSecret' => 'AKX********',
'redirectUri' => 'http://localhost:90',
'tenant' => 'e2*******3d',
'urlAuthorize' => 'https://login.microsoftonline.com/e2*******3d/oauth2/v2.0/authorize',
'urlAccessToken' => 'https://login.microsoftonline.com/e2******3d/oauth2/v2.0/token',
'urlAPI' => 'b37*******b02',
'scope' => 'b37*******b02/.default'
]);
$provider->defaultEndPointVersion = TheNetworg\OAuth2\Client\Provider\Azure::ENDPOINT_VERSION_2_0;

现在您可以使用以下代码检索访问 token 。

$accessToken = $provider->getAccessToken('client_credentials', [
'scope'=> $provider->scope
]);

您应该阅读此Accessing AAD OAuth2 protected API from PHP文档以获取更多信息。
