Get node details in Alfresco via back-end webscript

Question

I want to get node details via Backend webscript but I have some issues. I've tried two webscripts:

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

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

The first one gave me this response :

{
"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"
}

and the second :

{
        "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."
          ,"

Updated :

You can notice that in the second webSript the error says that my file UploadComponent.java does not refer to a folder. Does this script take a cm:folder as an argument. If there is another web-script that returns the node details (properties: nodeRef, mimetype, size... ) from nodeRef please show it to me. thanks !

Pro tip - You can see all of the available web scripts at http://localhost:8080/alfresco/service/index/uri/

You're supposed to use the CMIS web scripts where possible, and this also makes for the simplest request.

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

This returns the full set of properties for the nodeRef workspace://SpacesStore/8826b8f4-9f61-41a4-9f21-14ad5b6395ab.

Some of the XML you will receive is:

<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>

I also checked and this should give you the properties for any node regardless of where it is situated in your Alfresco instance.

There are a few webscripts you can use, such as the CMIS ones, but I think the simplest is probably the Slingshot Document Library Node webscript, with ID org/alfresco/slingshot/documentlibrary/node.get. You can read about it at http://localhost:8080/alfresco/service/script/org/alfresco/slingshot/documentlibrary/node.get

For a node with noderef workspace://SpacesStore/357b6dad-d434-4a46-a7e0-731df50e5e90 the URL is http://localhost:8080/alfresco/service/slingshot/doclib/node/workspace/SpacesStore/357b6dad-d434-4a46-a7e0-731df50e5e90, and the JSON returned looks something like:

I believe that's all the metadata and properties you're after. It's a webscript used by Share, so ought to be well tested and used. As you can see from the location section, it's a webscript which works for both site-based and non-site nodes equally

(If you do hit problems with it, probably best to ensure you're running the latest service pack if on enterprise, or newest release for community)
