如何检索 Alfresco 工作流的内容？

Question

我有一个包含音频内容的工作流程。我需要在其他应用程序中访问此内容（使用 javascript）。我正在尝试对此 URL:

使用 GET 方法

http://localhost:8086/alfresco/service/cmis/s/SpacesStore/i/1a7be6f8-0c50-4995-a211-1736642db06a/children?alf_ticket=TICKET_f9906d69befbc49668b92ddf372d62532a29ce7d

（在此URL中，id“1a7be6f8-0c50-4995-a211-1736642db06a”为工作流任务包的标识。）

但是，响应是下一个XML：

<?xml version="1.0" encoding="UTF-8"?>

我不知道如何使用这个 XML 来达到我的目的。我需要在我的自定义应用程序中收听内容（mp3 音频文件）并修改其属性。

我也在尝试下一个 URL (GET):

http://localhost:8086/alfresco/service/api/node/content/workspace/SpacesStore/1a7be6f8-0c50-4995-a211-1736642db06a

但结果是：Web 脚本状态 404 - 未找到

如何检索工作流的内容？这有一些 RESTful URL ?

感谢您的帮助。

您好，巴勃罗

Answer 1

最后，我使用其他 RESTful URL 解决了我的问题。因此，检索工作流内容的步骤如下：

1.我得到工作流任务的包ID（这是一个文件夹节点）：

GET /alfresco/service/api/task-instances/activiti$taskID

{
   "data": 
      {
         "id": "activiti$taskID",
         "url": "api\/task-instances\/activiti$taskID",
         "name": "wf:taskName",
         "title": "Task for this",
         "description": "Hello World !",
         "state": "IN_PROGRESS",
         "path": "api\/workflow-paths\/activiti$workflowID",
         "isPooled": false,
         "isEditable": true,
         "isReassignable": true,
         "isClaimable": false,
         "isReleasable": false,
         "outcome": null,
         "owner":
         {
            "userName": "admin",
            "firstName": "Admin",
            "lastName": "istrator"
         },
         "properties":
         {
            "bpm_percentComplete": 0,
            "bpm_description": "Hello World !",
            "bpm_hiddenTransitions": [],
            "bpm_package":"workspace:\/\/SpacesStore\/1a7be6f8-0c50-4995-a211-1736642db06a",
       ...........................................................
}

所以，包 ID 是：1a7be6f8-0c50-4995-a211-1736642db06a

2。通过包 ID，我得到了我需要的这个包的内容：

获取/alfresco/service/slingshot/node/workspace/SpacesStore/1a7be6f8-0c50-4995-a211-1736642db06a

.............................................    
"children": [
      {
         "name": {
            "name": "{http:\/\/www.alfresco.org\/model\/content\/1.0}grabacion1.mp3",
            "prefixedName": "cm:grabacion1.mp3"
        },
         "nodeRef": "workspace://SpacesStore/9ed7905d-7017-40e9-9514-93244b0a9a6a",
         "type": {
            "name": "{http:\/\/www.alfresco.org\/model\/content\/1.0}content",
            "prefixedName": "cm:content"
        },
         "assocType": {
            "name": "{http:\/\/www.alfresco.org\/model\/bpm\/1.0}packageContains",
            "prefixedName": "bpm:packageContains"
        },
         "primary": false,
         "index": 0
      }
   ],
.............................................

因此，内容 ID 为：9ed7905d-7017-40e9-9514-93244b0a9a6a

3。最后，我得到了我需要的内容：

获取/alfresco/service/api/node/content/workspace/SpacesStore/9ed7905d-7017-40e9-9514-93244b0a9a6a

如果您需要访问内容的属性，您可以使用第二步的 URL 和内容 ID（在此示例中：9ed7905d-7017-40e9-9514-93244b0a9a6a）。

你好:)
