我有FreeMarker模板，这是用于显示有关业务流程的一些数据的自定义字段。
让我们说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>
的相关部分share-config-custom.xml：
<config evaluator="task-type" condition="mswf:reviewTask">
<forms>
<form>
<field-visibility>
<show id="mswf:userDetails" />
</field-visibility>
<appearance>
<set id="userDetails" appearance="title" label="User Details" />
<field id="mswf:userDetails" set="userDetails" label="User Details">
<control template="/org/alfresco/components/form/controls/workflow/userdetails.ftl" />
</field>
<field id="transitions" set="response" />
</appearance>
</form>
</forms>
</config>
此模板包含一个表格，我想在其中显示将参与业务流程的用户列表（已分配的用户）。
在标签内部，<script></script>我想调用一个嵌入的 Alfresco WebScript（或我自己的 - 在这种情况下并不重要），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
，26205 == id流程实例所在的位置。
我得到以下信息：

除了我对这部分感兴趣的所有其他内容之外：
"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）。
要获得所有这些信息，我需要知道流程实例的 ID（26205在本例中）。
我可以在我的userdetails.ftl模板中确定这个标识符吗？
工作流 ID 确实是您的工作流中可用的变量之一，我建议您使用隐藏的表单控件将其添加到您的表单中hidden.ftl，然后，从您的 JS 片段中，使用 dom 通过 ID/名称访问该隐藏输入并使用它在你认为合适的逻辑中！
