以程式設計方式與工作流程互動 interacting-with-workflows-programmatically
當 自訂和延伸您的工作流程 您可以訪問工作流對象:
使用工作流程Java API using-the-workflow-java-api
工作流程Java API包含 com.adobe.granite.workflow
包和幾個子包。 API最重要的成員是 com.adobe.granite.workflow.WorkflowSession
類別。 此 WorkflowSession
類提供了對設計時間和運行時工作流對象的訪問:
- 工作流程模型
- 工作項目
- 工作流程例項
- 工作流程資料
- 收件匣項目
類還提供了幾種干預工作流生命週期的方法。
下表提供與工作流程以程式設計方式互動時要使用的多個關鍵Java對象的參考文檔的連結。 下面的示例演示如何獲取和使用代碼中的類對象。
在ECMA指令碼中取得工作流程物件 obtaining-workflow-objects-in-ecma-scripts
如 找到指令碼, AEM(透過Apache Sling)提供執行伺服器端ECMA指令碼的ECMA指令碼引擎。 此 org.apache.sling.scripting.core.ScriptHelper
類別會立即供指令碼使用,因為 sling
變數。
此 ScriptHelper
類提供對 SlingHttpServletRequest
最終獲得 WorkflowSession
對象;例如:
var wfsession = sling.getRequest().getResource().getResourceResolver().adaptTo(Packages.com.adobe.granite.workflow.WorkflowSession);
使用工作流程REST API using-the-workflow-rest-api
工作流程主控台大量使用REST API;因此,本頁面說明工作流程的REST API。
REST API支援下列動作:
- 啟動或停止工作流服務
- 建立、更新或刪除工作流模型
- 啟動、暫停、繼續或終止工作流實例
- 完成或委派工作項目
POST
請求。在此頁面中,假設AEM在連接埠的localhost上執行 4502
而安裝環境是「 /
"(根)。 如果不是安裝的情況,則需要相應地調整HTTP請求所應用的URI。
支援的呈現 GET
要求為JSON呈現。 的URL GET
應該有 .json
