Posting form data to a web script

[stiegld]

Hi folks,

Happy holidays to all.

I am trying to write a webscript that accepts formdata from a form. The webapp sending the form, however, uses a commons-httpclient proxy to do authentication and to separate the alfresco instance from the web application.

I can't seem to get the web script to accept any arguments. Here is an excerpt from the webscript code:

script: {var authorEmail = null;var content = null;var comment = null;for (arg in args){  logger.log(arg + "=" + args[arg]);}// log each argument (assuming one or more values have been provided for each)for (arg in argsM){  for each (val in argsM[arg])  {     logger.log(arg + "=" + val);  }}// locate file attributesfor each (field in formdata.fields){  if (logger.isLoggingEnabled()) {    logger.log("found field "+field.name+" with value "+field.value);  }  if (field.name == "email")  {    authorEmail = field.value;  }  else if (field.name == "comment")  {    content = field.value;  }}if (logger.isLoggingEnabled()) {//    logger.log("formdata is +"formdata.fields);   logger.log("email is "+authorEmail);   logger.log("content is "+content);}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

As you can see, this excerpt simply tries to display parameters submitted, and the only output is

email is null
content is null

The commons-http client excerpt is below:

         client.getHttpConnectionManager().getParams()            .setConnectionTimeout(5000);      client.getState().setCredentials(AuthScope.ANY,            new UsernamePasswordCredentials(username, password));      PostMethod post = new PostMethod(url);      post.setDoAuthentication(true);      post.setRequestHeader("Content-Type", "multipart/form-data");      Part[] parts = { new StringPart("email", authorEmail),            new StringPart("comment", comment) };      post.setRequestEntity(new MultipartRequestEntity(parts, post            .getParams()));      try {         int status = client.executeMethod(post);         System.out.println("received status " + status);         if (status > 299) { // there was an error               System.out.println(post.getResponseBodyAsString());         }      } finally {         post.releaseConnection();      }   }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I've also tried to send data using NameValuePairs and the setRequestBody () method, to no avail. I know that the Content-Type is set correctly because if I change it or remove it, the formdata object is never initialized in the script.

Any ideas?

try this out

//create HttpClient objectHttpClient client = new HttpClient();//pre-authenticate with alfresco serverclient.getParams().setAuthenticationPreemptive(true);Credentials loginCreds = new UsernamePasswordCredentials("admin", "admin");//Use AuthScope.ANY since the HttpClient connects to just one URLclient.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).
