Alfresco媒體查看器web預覽可擴展性

Question

因此，我遵循Will Abson's指南和源代碼在Alfresco中擴展自定義媒體查看器。 雖然我有幾個問題。 我已經使用4.2+ Alfresco，因此不需要使用head.ftl作爲棄用，我使用第二個可擴展性模塊自動添加我自己的配置，但是：BOD： 我如何訪問我的web-preview.get.js中的jsNode？或者更好，有沒有辦法訪問正在顯示的節點的屬性值和方面？ 我知道服務器端和客戶端var jsNode = new Alfresco.util.Node(model.widgets[i].options.nodeRef)和var jsNode = AlfrescoUtil.getNodeDetails(model.widgets[i].options.nodeRef); 這是在另一個問題here中提到的，但它似乎像默認值，如mimeType，大小，nodeRef除外，我無法使用這些來從文件。 這些都是我的變化：

網絡preview.get.js在-config文件夾我的自定義媒體觀衆的

//<import resource="classpath:/alfresco/templates/org/alfresco/import/alfresco-util.js"> 
if (model.widgets) 
{ 
    for (var i = 0; i < model.widgets.length; i++) 
    { 
     var at = "test"; 
     //var jsNode = AlfrescoUtil.getNodeDetails(model.widgets[i].options.nodeRef); 
     //var author = jsNode.properties["cm:author"]; 
     var widget = model.widgets[i]; 
     if (widget.id == "WebPreview") 
     { 
     var conditions = []; 
     // Insert new pluginCondition(s) at start of the chain 
     conditions.push({ 
      attributes: { 
       mimeType: "application/pdf" 
      }, 
      plugins: [{ 
       name: "PDF", 
       attributes: { 
       } 
      }] 
     }); 
     var oldConditions = eval("(" + widget.options.pluginConditions + ")"); 
     // Add the other conditions back in 
     for (var j = 0; j < oldConditions.length; j++) 
     { 
      conditions.push(oldConditions[j]); 
     } 
     // Override the original conditions 
     model.pluginConditions = jsonUtils.toJSONString(conditions); 
     widget.options.pluginConditions = model.pluginConditions; 
     } 
    } 
}

，你可以通過註釋部分來查看我嘗試了不同的方法來訪問節點屬性/值，甚至是簡單的字符串，但我肯定缺少某些東西。 謝謝。

Answer 1

如果你看看源代碼，你會看到一個輔助方法是什麼都沒有比做到var url = '/slingshot/doclib2/node/' + nodeRef.replace('://', '/');

遠程調用所以來看看是什麼庫WebScript正在返回EN它匹配你需要的屬性。

我通常不使用這個，我知道肯定/api/metadatareturns的所有屬性。
