Upload documents to alfresco using REST Api

Upload documents to alfresco using REST Api:

Prerequisites:-----

Following jar files are required (httpcomponents-client-4.3.4):

commons-codec-1.6.jar

commons-logging-1.1.3.jar

commons-httpclient-3.1.jar

httpcore-4.1.3.jar
junit-4.12.0.jar

**************************************************************************
Alfresco's Login (POST) REST Api '/alfresco/service/api/login' return authentication ticket in response.

This is how authTicket will look like: <ticket>TICKET_4b36ecaxxxxx5cdc5d782xxxxxxxxxxxx</ticket>

In the response you will get the authentication ticket, this authentication ticket will be used in all subsequent requests in order to get authenticated with alfresco.

In the subsequent request (as example given below in Test class) i am trying to upload a file to alfresco using REST URI::

'/alfresco/service/api/upload?alf_ticket=TICKET_4b36ecaxxxxx5cdc5d782xxxxxxxxxxxx'

Here i am passing alf_ticket as a parameter with the 'authentication ticket' value which i got from '/alfresco/service/api/login' REST call.

For more details visit: http://docs.alfresco.com/5.0/references/RESTful-intro.html

     uploadDir));
  }

  System.out.println("Response of upload operation >>>: "+responseBody);
  assertEquals(true, responseBody.toString().contains("File uploaded successfully"));
 }
}

Further implementations:

If you want to upload a new version of already existing file, you just have to get the nodeRef of existing file and pass below given parts parameter to same Upload REST API call. See documentUpload method above, I have highlighted the parts parameter. You have to replace the parts parameter and upload the file.

// To upload the file as a new version once the file was uploaded, then send following parameters in
// parts array. Note that we have to remove the "override" parameter from the parts array and add
// "updateNodeRef" parameter.
//uploaddirectory can accept a folder name or a folder path. Do not include documentLibrary in the path

final Part[] partsUploadAsVersion = {
     new FilePart("filedata", docName, docFileObj, mimeType,null),
     new StringPart("filename", docName),
     new StringPart("siteid",siteID),
     new StringPart("containerid","documentLibrary"),
     new StringPart("uploaddirectory",uploadDir), //Optional Parameter
    new StringPart("updateNodeRef ", nodeRefOfExistingFile) 
  };

Note:- You will still need the old parts array to upload the file for the first time. Once file is uploaded then to upload new version of that file (node) you have to use above given option.

If you want to upload file to a target destination for example: 'Shared' folder in the alfresco repository, then you can use the destination parameter to pass the nodeRef and additionally pass the folder name inside the destination node.

Here is the sample:

final Part[] partsUploadAsVersion = {
     new FilePart("filedata", docName, docFileObj, mimeType,null),
     new StringPart("filename", docName),
     new StringPart("destination", destinationNodeRef), // nodeRef of 'Shared' folder i.e. workspace://SpacesStore/85d2a84d-271b-41b1-9449-02f5942893a0
     new StringPart("uploaddirectory",uploadDir), //Optional Parameter
    new StringPart("overwrite ", "true") 
  };

Here is the detailed description for upload api:

POST /alfresco/service/api/upload

HTML form data

filedata, (mandatory) HTML type file
You must specify one of:
- destination (the folder NodeRef where the node will be created)
- updateNodeRef (the NodeRef of an existing node that will be updated)
- siteid and containerid (the Site name and the container in that site where the document will be created)
uploaddirectory - name of the folder (either in the site container or the destination) where the document will be uploaded. This folder must already exist
description - Description for a version update (versionDescription)
contenttype - The content type that this document should be specialised to
majorversion
overwrite
thumbnails

Return content

nodeRef

Return status: STATUS_OK (200)

The web script description document specifies the following options:

Value	Description
`json`	The default response format
`user`	The authentication access
`required`	The transaction level
`any`	The format style

----------------------------------------------------------------------------------------------------------------------
If you want to download or delete a node/file then you can write a piece of code taking the reference of above code to download/delete the node/file.

REST API for download file/node is: (It should be HTTP Get request)

GET /alfresco/service/api/node/content/{store_type}/{store_id}/{id}?a=false&alf_ticket={TICKET}

Example:

http://127.0.0.1:8080/alfresco/service/api/node/content/workspace/SpacesStore/85d2a84d-271b-41b1-9449-02f5942893a0?a=false&alf_ticket=TICKET_5550fa5e9b87bead8f008e906185e023b7ce21ed

Where:
a: means attach. if true, force download of content as attachment. Possible values are true/false
store_type: workspace
store_id: SpacesStore
id: nodeRefId (UUID of the node)

A StoreRef is comprised of:

Store Protocol - that is, the type of store
Store Identifier - the id of the store

Example storeRefs are:

workspace://SpacesStore (store_type://store_id)
version://versionStore (store_type://store_id)
archive://SpacesStore (store_type://store_id)

For more on Download Services visit my another post here: Downloading Content From Alfresco

--------------------------------------------------------------------------------------------------------------------------------

REST API for delete file/node is: (It should be HTTP Delete request)

DELETE /alfresco/service/api/node/{store_type}/{store_id}/{id}?alf_ticket={TICKET}

Example:

http://127.0.0.1:8080/alfresco/service/api/node/workspace/SpacesStore/0a1b9c30-39a6-4249-8f2b-78c4e8b29b2c?alf_ticket=TICKET_5550fa5e9b87bead8f008e906185e023b7ce21ed

Note: You need to pass alf_ticket as a parameter for very REST call. You can see, i am adding alf_ticket parameter for upload, download and delete examples above.
