用户身份验证失败：null
Authentication failed for user: null
我有一个 API "Vignette Collab" 在 Apache 堆栈上 运行 Java，我继承了一个遗留代码库，需要找到这个错误的来源显然，最后一位开发人员构建了一个无法正常工作的功能，这就是错误所在，但没有更多信息。它使用 Drupal 网络服务模块，发送调用的代码如下所示
$node = $variables['node'];
$service = wsclient_service_load('collab_folders');
if($node->field_oid1):
$param1 = $node->field_oid1['und'][0]['value'];
$params1 = array('user'=>'myUser','password'=>'myPass','oid'=>$param1);
$results1 = $service->getChildren($params1);
$variables['collabresults1'] = $results1;//
知道从哪里开始查找此错误或它可能意味着什么吗？

问题似乎出在这一行：$results1 = $service->getChildren($params1);。 UnsupportedOperationException 属于 Java 集合框架，这意味着您正在尝试对数组 $params2 执行一些 java api 不支持的操作。我首先要看的是 java 的版本 运行 和 Vignette Collab api 所需的 java 的版本。在我看来，可能需要比您当前使用的更高版本的 java。
您可能还想深入了解 api 以了解 getChildren() 的作用，并确保您传递的参数值正确。
