在MuleStudio中使用Drupal連接器時出錯

Question

我想在MuleStudio項目中使用Drupal連接器。但我已經測試過的所有操作（創建節點，索引節點，...），我得到了同樣的錯誤：

ERROR 2013-08-20 11:19:00,291 [[drupal-integration].connector.http.mule.default.receiver.02] org.mule.retry.notifiers.ConnectNotifier: Failed to connect/reconnect: Work Descriptor. Root Exception was: null. Type: class org.mule.api.ConnectionException

這是我的配置XML：

我已經成功安裝並配置了REST服務器。我正在使用新的Studio 3.5 Andes Runtime和新的連接器。

錯誤：org.mule.modules.drupal.client.DrupalRestClient.login（DrupalRestClient.java:125）

涉及扔在下面的try/catch

try { 
    r = this.client.resource(new URI("http", null, server, port, apiUrl 
     +"/"+DrupalCollection.User.getEndpoint() +"/" + LOGIN, null, null)); 
} catch (URISyntaxException e) { 
    throw new ConnectionException(ConnectionExceptionCode.UNKNOWN, 
    null, null); 
} 

因此，有構建URI的問題。嘗試在apiUrl：/ rest/api之前添加一個前導斜槓。

「/ rest/api」也是默認值，因此您可以完全刪除apiUrl屬性。

文檔不太清楚 - 但它需要apiUrl是絕對路徑，而另一個則是相對的。
