Alfr - Working with Content

Roy Wetherall

Introduction

Alfr allows you to work with content directly within the Alfresco repository.

Setup

First include the alfr library.

library(alfr)

In order to communicate with the Alfresco repository you must first establish a session connection. The location of the respository is required to do this, along with valid user credentials.

session <- alf_session("http://localhost:8080", "admin", "admin")

Uploading Content

All content is stored on a repository node so before we can upload binary content we must first create a node to store it within. In this example we are creating a node called myFile2.txt in the folder test. -root- is used to reference the root repository node.

my_file <- alf_node.new(session, "-root-", list(name="myFile2.txt", nodeType="cm:content", relativePath="test"))

Now content can be uploaded into the nodes content property where it will be stored in the Alfresco repository.

my_file <- my_file$content$update("resources/testuploaddoc.txt")

Reading Content

Get a reference to the node you want to read content from.

my_file <- alf_node.new(session, "-root-", relativePath="test/myFile2.txt")

Content stored in a repository node can then be read to the client by opening a connection and reading the contents.

con <- my_file$content$as.file("resources/download.txt") %>% file("r")
readLines(con)
close(con)

Deleting Content

With a reference to the node that you want to delete from the repository.

alf_node.delete(session, node$id)

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
