Question

我正在使用Liferay 6.1.1 CE。

通过在xml文件（leaveapproval.xml）中编写定义并将其加载到服务器，我创建了一个多级kaleo工作流（即具有两个级别的批准）。它工作正常，因为我在博客中测试了这个工作流程。

现在，我希望在完成第二级审批后将工作流程的内容提交给Web服务。

我如何处理工作流程的内容？

有可能吗？

Answer 1

要在某个工作流程步骤中以编程方式运行任何内容，您通常只需要<script>标记，就像您正在更新状态一样。

因此，在您批准的<state>中，您可能希望添加另一个<action>标记，这个标记用于处理Web服务调用（并让其他操作保持原样））。

您用于脚本的语言取决于您的习惯。我使用groovy，因为它很好地处理普通的java代码，这就是我所知道的。

以下是它的外观（仅包含最后<state>代码）：

<state>
    <name>approved</name>
    <metadata>
        <![CDATA[
        {"xy":[380,51]}
        ]]> 
    </metadata>
    <actions>
        <action>
            <name>approve</name>
            <script>
                <![CDATA[
                Packages.com.liferay.portal.kernel.workflow.WorkflowStatusManagerUtil.updateStatus(
                    Packages.com.liferay.portal.kernel.workflow.WorkflowConstants.toStatus("approved"),
                    workflowContext);
                ]]>
            </script>
            <script-language>javascript</script-language>
            <execution-type>onEntry</execution-type>
        </action>
        <action>
            <name>submit-web-service</name>
            <script>
                <![CDATA[
                import java.io.*
                import java.net.*

                URL url = new URL(
                    "www.my-web-service.com/api/whatever?theParam=" +
                        ${theRelevantContextVariable});

                URLConnection urlConnection = url.openConnection();

                // if necessary to read response data:
                // BufferedReader bufferedReader = new BufferedReader(
                //    new InputStreamReader(urlConnection.getInputStream()));
                // String something = bufferedReader.readLine();
                // etc.
                ]]>
            </script>
            <script-language>groovy</script-language>
            <execution-type>onEntry</execution-type>
        </action>
    </actions>
</state>

您可能需要POST请求，在这种情况下，您将以不同方式实施Web服务调用。但无论如何，您都要在动作标签中编写Web服务代码。这样的事情应该有效。
