I'm using a Java service that calls a Webscript and send to it the arguments (including a file) without problems…
May the problem be in the service you are using to upload the file? Can you post the code?

Got it working using apache lib. So definitely something wrong when I build the request using URLConnection.

Alfresco is working fine for me when I use GET- and PUT-type requests (haven't ventured into DELETE yet ). POST just isn't working though.

I have a similar problem to that described in the first post in this thread. In my web script the fields in the formdata are all empty. I think I have ruled out authentication problems (the web script is executing and sending back its own error code).

This is with Alfresco Community v3.2.0 and using C# code to generate the multipart form data.

Here is a run-down of what happens:

The post request is:


POST /alfresco/service/traqsAPI/testUpload?alf_ticket=TICKET_……………………ad61da HTTP/1.1
‍‍‍

The headers are:


Content-Type: multipart/form-data; boundary=BEACF86DE59B48bbB49F82CB55A3D009
Host: alfrescoserver:8080
Content-Length: 336
Expect: 100-continue
‍‍‍‍‍‍

Alfresco replies with "100 Continue" and a blank header block.

Now the content is sent:


–BEACF86DE59B48bbB49F82CB55A3D009
Content-Disposition: form-data; name="test"

This is a test value.
–BEACF86DE59B48bbB49F82CB55A3D009
Content-Disposition: form-data; name="filedata"; filename="filename.xml"
Content-Type: text/xml

<h3>Heading</h3><p>This is some text for the test.</p>
–BEACF86DE59B48bbB49F82CB55A3D009

‍‍‍‍‍‍‍‍‍‍‍‍‍

However, the content fields are not getting through; I know this because Alfresco replies with:


<response>
  <status>
    404
    <name>Not Found</name>
    <description>Requested resource is not available.</description>
  </status>
  <message>No content was supplied in the request. Field names found were ''</message>
  <exception></exception>
  <callstack>
  </callstack>
  <server>Alfresco Community v3.2.0 (2039) schema 2,019</server>
  <time>04-Nov-2009 22:16:30</time>
</response>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The <message> in the XML above is generated by my web script:


function main(){

   // Get values from form data.
    var filename = null;
    var content = null;
    var mimetype = null;
    var test = null;
   // Parse file attributes
   var fieldNames = "";
   for each (field in formdata.fields) {
      fieldNames = fieldNames + field.name + " ";
      switch (String(field.name).toLowerCase()) {
         case "filedata":
            if (field.isFile) {
               filename = field.filename;
               content = field.content;
               mimetype = field.mimetype;
            }
            break;

         case "test":
            test = field.value;
            break;
      }
   }
   
   if(content == null){
      status.code = 404;
      status.message = "No content was supplied in the request. Field names found were '" + fieldNames + "'";
      status.redirect = true;
      return;
   }


   …snipped…
}   

main();
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I've combed the forum and the web for examples and my multipart format seems to be right, but someone here may be able to see my mistake. Or possibly you'll tell me that I just have to use java :lol:.

Thank you.

Found the problem: I missed two hyphens from the last line of my form data content.

It should have been:


–BEACF86DE59B48bbB49F82CB55A3D009–
‍‍‍

instead of


–BEACF86DE59B48bbB49F82CB55A3D009
‍‍‍

It is working perfectly now.
