通过后端webscript在Alfresco中获取节点细节

Question

我想通过后端webscript获得节点细节，但我有一些问题。我试过两个webscript:

• alfresco/service/slingshot/doclib2/node/workspace/SpacesStore/a10a0777-40f4-42da-b236-8845eb26294e

• alfresco/service/slingshot/doclib/node/workspace/SpacesStore/a10a0777-40f4-42da-b236-8845eb26294e。

第一个给了我这样的回应:

{
"status" : 
{
"code" : 410,
"name" : "Gone",
"description" : "Resource is no longer available at the server and no forwarding address is known."
},  
"message" : "Location is 'null'. (No permission?)",  
"exception" : "",
"callstack" : 
[ 
],
"server" : "Enterprise v4.2.0 (r57217-b28) schema 6,034",
"time" : "Jun 10, 2014 10:28:15 AM"
}

和第二个:

{
        "status" : 
      {
        "code" : 500,
        "name" : "Internal Error",
        "description" : "An error inside the HTTP server which prevented it from fulfilling the request."
      },  
      "message" : "05100028 Wrapped Exception (with status template): 05100077 Failed to execute script 'classpath*:alfresco/templates/webscripts/org/alfresco/slingshot/documentlibrary/node.get.js': 05100076 Site container UploadComponent.java does not refer to a folder.",  
      "exception" : "org.springframework.extensions.webscripts.WebScriptException - 05100028 Wrapped Exception (with status template): 05100077 Failed to execute script 'classpath*:alfresco/templates/webscripts/org/alfresco/slingshot/documentlibrary/node.get.js': 05100076 Site container UploadComponent.java does not refer to a folder.",
      "callstack" : 
      [ 
          ""      ,"org.alfresco.repo.site.SiteServiceException: 05100076 Site container UploadComponent.java does not refer to a folder."
          ,"

更新:

你可以注意到，在第二个webscript的错误说，我的文件UploadComponent.java不引用一个文件夹。这个脚本是否接受cm:文件夹作为参数?如果有另一个web脚本返回节点的详细信息(属性:nodeRef, mimetype, size…)请拿给我看看。谢谢!

专业提示-您可以在http://localhost:8080/alfresco/service/index/uri/看到所有可用的web脚本

你应该在可能的地方使用CMIS web脚本，这也使得最简单的请求。

http://<MyAlfresco>/alfresco/service/cmis/i/8826b8f4-9f61-41a4-9f21-14ad5b6395ab

这将返回nodeRef workspace://SpacesStore/8826b8f4-9f61-41a4-9f21-14ad5b6395ab的完整属性集。

您将收到的一些XML是:

<cmis:properties>
    <cmis:propertyInteger propertyDefinitionId="cmis:contentStreamLength" displayName="Content Stream Length" queryName="cmis:contentStreamLength"><cmis:value>36864</cmis:value></cmis:propertyInteger>
    <cmis:propertyId propertyDefinitionId="cmis:objectTypeId" displayName="Object Type Id" queryName="cmis:objectTypeId"><cmis:value>cmis:document</cmis:value></cmis:propertyId>
    <cmis:propertyString propertyDefinitionId="cmis:versionSeriesCheckedOutBy" displayName="Version Series Checked Out By" queryName="cmis:versionSeriesCheckedOutBy"/>
    <cmis:propertyBoolean propertyDefinitionId="cmis:isPrivateWorkingCopy" displayName="Is private working copy" queryName="cmis:isPrivateWorkingCopy"/>
    <cmis:propertyId propertyDefinitionId="cmis:versionSeriesCheckedOutId" displayName="Version Series Checked Out Id" queryName="cmis:versionSeriesCheckedOutId"/>
    <cmis:propertyId propertyDefinitionId="cmis:versionSeriesId" displayName="Version series id" queryName="cmis:versionSeriesId"><cmis:value>workspace://SpacesStore/8826b8f4-9f61-41a4-9f21-14ad5b6395ab</cmis:value></cmis:propertyId>
    <cmis:propertyBoolean propertyDefinitionId="cmis:isLatestVersion" displayName="Is Latest Version" queryName="cmis:isLatestVersion"><cmis:value>true</cmis:value></cmis:propertyBoolean>
</cmis:properties>

我也检查了，这应该会给你任何节点的属性，不管它位于Alfresco实例的哪个位置。

你可以使用一些web脚本，比如CMIS的，但我认为最简单的可能是Slingshot文档库节点web脚本，ID为org/alfresco/slingshot/documentlibrary/node.get。你可以阅读http://localhost:8080/alfresco/service/script/org/alfresco/slingshot/documentlibrary/node.get

对于nodeef为workspace://SpacesStore/357b6dad-d434-4a46-a7e0-731df50e5e90的节点，URL为http://localhost:8080/alfresco/service/slingshot/doclib/node/workspace/SpacesStore/357b6dad-d434-4a46-a7e0-731df50e5e90，返回的JSON看起来像:

},
"permissions":
{
  "inherited": true,
  "roles":

     "ALLOWED;administrator;All;INHERITED",
     "ALLOWED;ROLE_OWNER;All;INHERITED"
  ],
  "userAccess":
  {
     "permissions": true,

     "cancel-checkout": false,

  }
},
"custom": {},
"actionLabels":
{
}
}
}

我相信这就是你想要的所有元数据和属性。这是一个共享使用的web脚本，所以应该经过很好的测试和使用。从位置部分可以看到，这是一个webscript，它可以同时用于基于站点和非站点的节点

(如果遇到问题，最好确保您运行的是企业版的最新服务包，或社区版的最新版本)
