Alfresco 如何在工作流表单中获取工作流实例的id？

我有FreeMarker模板，它是用于显示有关业务流程的一些数据的自定义字段

比如说，

userdetails.ftl

：

<@link href="${url.context}/res/components/workflow/workflow-form.css" group="workflow"/>
<#include "/org/alfresco/components/form/controls/common/utils.inc.ftl" />

<div class="form-field">
   <div id="...">
      <table id="..." class="yui-dt">
         <tr>
            <th class="yui-dt-liner">Field_1</th>
            <th class="yui-dt-liner">Field_2</th>
            <th class="yui-dt-liner">Field_3</th>
            <th class="yui-dt-liner">Field_4</th>
            ...
            <th class="yui-dt-liner">Field_N</th>
         </tr>
         ...
      </table>
   </div>
</div>

<script>

// Here I want to call REST back-end and parse the JSON response

</script>

此模板包含一个表，我希望在其中显示将参与业务流程（已分配）的用户列表

Inside tags

我想调用一个嵌入的Alfresco WebScript（或者我自己的—在本例中并不重要），它会返回有关业务流程的所有必要信息：

http://localhost:8080/alfresco/api/-default-/public/workflow/versions/1/processes/26205/variables

，其中流程实例的

26205==id

我得到以下信息：

               "value":0
            }
         }
      ]
   }
}

除此之外，我还对这一部分感兴趣：

"entry":{
   "name":"bpm_assignees",
   "type":"cm:person",
   "value":[
      "first",
      "second"
   ]
}

以下是将参与业务流程的用户列表（在此特定实例中）

要获取所有这些信息，我需要知道流程实例的ID（

26205

）

我可以在我的

userdetails.ftl

模板中确定此标识符吗？

工作流ID确实是工作流中可用的变量之一，我建议您使用隐藏表单控件

hidden.ftl

将其添加到表单中，然后从您的JS代码段，使用dom按ID/名称访问隐藏的输入，并在您认为合适的逻辑中使用它

{“条目”：{“截止日期”：“2017-03-12T20:00:00.000+0000”‌​processDefinitionId“‌​:“合同批准：‌​116:26804‌​d:“26938”，“名称”：“R”‌​eview Task“，…}正如您所说，您可以从这里获取您的进程ID。通过此ID，您可以调用此url‌​/版本/1/processe‌​s/26938/variables是这样的。如果您从url获取id就可以了。如果您想获取特定用户的工作流实例id和任务id，那么也可以使用rest api.freemarker api，或者您也可以使用java类获取它。

"entry":{
   "name":"bpm_assignees",
   "type":"cm:person",
   "value":[
      "first",
      "second"
   ]
