Can someone PLEASE provide just ONE example of an upload

dallinns — Wed, 01 Jun 2011 20:26:23 GMT

I am ripping my hair out trying to get the upload webscript (alfresco/service/api/upload) to work. It seems simple enough but I can't get it to work for the life of me. First of all, which parameters are necessary for NEW FILE UPLOAD (i.e. How can I possibly provide an updatenoderef if I'm not updat

I also tried to implement uploading file and ask lots of questions on the forum, but no one has answered this simple question. Somebody can answer?

Hi Guys,
This is a piece of curl code I found that uses curl to upload to alfresco.

In the end I could only get it to upload under the Sites directory for Alfresco Share. I think this is a limitation of the ${ALFRESCO_SERVER}/service/api/upload URL so in the end I wrote my own web script to handle uploads.

I hope this helps. Have a search around for key words like siteid and containerid for more info, although there isn't much that I could find.

P.S. you will need to modify the USERNAME and PASSWORD variables.

#!/bin/bash
#
# Alfresco upload script with CURL by LouiSe@louise.hu
#
# Usage: alfresco_uploader.sh
#
# ./alfresco_uploader.sh /tmp/some.pdf someSite documentLibrary someDir
#

ALFRESCO_SERVER=http://localhost:8080/alfresco
USERNAME="admin"
PASSWORD="admin"

#CURL_VERBOSE=-v
CURL_VERBOSE=-s
CURL_METHOD=POST
FILENAME=`basename $1`
MIMETYPE=`file –brief –mime-type $1`
UPLOAD_SERVICE_URL=${ALFRESCO_SERVER}/service/api/upload

echo "Uploading: ${FILENAME} ($MIMETYPE) to ${ALFRESCO_SERVER}"

    -F filedata=@$1 -F siteid="$2" -F containerid="$3" \
    -F uploaddirectory="$4" \ -F filename="${FILENAME}" \
    -F contenttype="${MIMETYPE}" "${UPLOAD_SERVICE_URL}" \
    | grep 'description' | cut -d ':' -f 2 | tr -d '\"'

In the Alfresco wiki I have updated the Upload Form example that now should work on the latest version of Alfresco:

Here is an example in Java. The method uploads a file using Commons http client and Alfresco RESTful API. It seems to me that site id, container id and upload directory, in addition to the file data itself, are the minimum parameters to upload a file. Assuming that you have a folder "abc" created in "Document Library" under site "demo", the parameters would be
siteId="demo"
containerId="documentlibrary"
uploadDirectory="/abc"

Note that the code uses alf_ticket for authentication when calling upload, which you can get from the login webscript. Hope this helps.

   public String upload(File file, String siteId, String containerId, String uploadDirectory) {

      String json = null;

      DefaultHttpClient httpclient = new DefaultHttpClient();

            HttpHost targetHost = new HttpHost("localhost", 8080, "http");

      try {
         HttpPost httppost = new HttpPost("/alfresco/service/api/upload?alf_ticket="
               + this.ticket);

         FileBody bin = new FileBody(file);
         StringBody siteid = new StringBody(siteId);
         StringBody containerid = new StringBody(containerId);
         StringBody uploaddirectory = new StringBody(uploadDirectory);

         MultipartEntity reqEntity = new MultipartEntity();
         reqEntity.addPart("filedata", bin);
         reqEntity.addPart("siteid", siteid);
         reqEntity.addPart("containerid", containerid);
         reqEntity.addPart("uploaddirectory", uploaddirectory);

         httppost.setEntity(reqEntity);

         log.debug("executing request:" + httppost.getRequestLine());

         HttpResponse response = httpclient.execute(targetHost, httppost);

         HttpEntity resEntity = response.getEntity();

         log.debug("response status:" + response.getStatusLine());

         if (resEntity != null) {
            log.debug("response content length:"
                  + resEntity.getContentLength());

            json = EntityUtils.toString(resEntity);
            log.debug("response content:" + json);
         }

         EntityUtils.consume(resEntity);
      } catch (Exception e) {
         throw new RuntimeException(e);
      } finally {
         httpclient.getConnectionManager().shutdown();
      }

      return json;
    }

Simple curl example, tested against Alfresco Community 4.0.d on Windows XP

curl -v -X POST -F filedata=@myUpload.doc -F siteid=mysite -F containerid=documentLibrary -F uploaddirectory=/uploads http://username:password@localhost:8080/alfresco/service/api/upload‍

This will upload into documentLibrary/uploads within the specific Share site (mysite). Note that the user performing the upload must be a member of that Share site (and presumably needs at least Contributor access?).

I'm unsure why the leading slash is needed for the uploaddirectory, since the script seems to remove it again. But omitting it causes the file to be saved into the parent folder i.e. documentLibrary!

The actual webscript is located in tomcat\webapps\alfresco\WEB-INF\classes\alfresco\templates\webscripts\org\alfresco\repository\upload - looking at the source is the best way to understand it as the online Alfresco documentation is not very detailed (http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Freferences%2FRESTful-UploadUploadPost.html)

thank you dnallsopp
you have give the easiest methode of uploading file in alf

this is how we do it in php for those who interest

<?php

$lien = 'http://userassword@localhost:8080/alfresco/service/api/upload';

//filedata=@myUpload.doc -F siteid=mysite -F containerid=documentLibrary -F uploaddirectory=/uploads

$fichier = 'fichier_a_uploader.txt';
$postfields = array(

   'filedata' =>'@' . realpath($fichier),
   'siteid' => 'mysite',
   'containerid' =>'documentLibrary',
   'uploaddirectory' =>'/UTILITAIRE'


);

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, $lien);
curl_setopt($curl, CURLOPT_COOKIESESSION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postfields);

$return = curl_exec($curl);
curl_close($curl);

if (!preg_match('#Username and password do not match#i', $return))
{
   echo 'Connexion ok. '.$return;
}
else

Can you guys help me with this? Have you done this already?

Thanks in Advance

Out-of-the-box web script example URL as follows - http://serverort/alfresco/s/api/node/workspace/SpacesStore/{nodeid}/content - should get the content for the given node. Change the server, port and nodeid in this URL as per your setup.

Hope this helps.
