Hi folks,Happy holidays to all.I am trying to write a webscript that accepts formdata from a form.

try this out


//create HttpClient object
HttpClient client = new HttpClient();

//pre-authenticate with alfresco server
client.getParams().setAuthenticationPreemptive(true);

Credentials loginCreds = new UsernamePasswordCredentials("admin", "admin");

//Use AuthScope.ANY since the HttpClient connects to just one URL
client.getState().setCredentials(AuthScope.ANY , loginCreds);

PostMethod post= new PostMethod(url);

post.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
                                new DefaultHttpMethodRetryHandler(3, false));

//Alfresco only reads the POST parameters if they are in the body of the request, so we need to create a RequestEntity to populate the body.

Part[] parts = {new StringPart("email", authorEmail), new  StringPart("submit", "Post"), new StringPart("comment", comment)};

        MultipartRequestEntity entity = new MultipartRequestEntity(parts, post.getParams());

post.setRequestEntity(entity);

 try
        {
            //subimit the request and get the response code
            int statusCode = client.executeMethod(method);
            //Check for code 200
            if (statusCode != HttpStatus.SC_OK)
            {
                throw new HttpException("HTTP returned status code " + statusCode);
            }

            InputStream responseBody = post.getResponseBodyAsStream();
}

I removed the Content-Type property altogether and also added the preemptive authentication flag and it started working.

Thanks for the reply!

P.S. I'm having a problem using the createAssociation method in the ScriptNode API in a web script (no association is created, no error is thrown). I wonder if anyone else has this problem or it's a known issue.

I have run through the createAssociation test scripts and they execute ok. Which version of Alfresco are you using? Can you provide example of your code/model?

Thanks,

Kevin

Hi Kevin,

Upon revisiting this, I've found it to work now with no changes (I guess it worked before and something else had been wrong).
