Getting POST parameters for a JavaScript webscript

[patorjk]

For webscripts written in JavaScript, I'm able to get parameters in the query string via the "args" object. However, after looking over the object list in Chapter 9 of "Professional Alfresco", looking through the wiki, playing around a bit, and searching the web, I seem to be unable to find a way to get POST parameters (parameters passed in the HTTP message's body). Is there a way to access these parameters from a webscript?

As an example, here is how I'm passing the variables to the webscript from client side (this is for a Share dashlet that's talking to the repository):

var sUrl = Alfresco.constants.PROXY_URI + "folder-search";
var postData = "searchTxt=" + document.getElementById("jtf_text").value;
var request = YAHOO.util.Connect.asyncRequest('POST', sUrl, callback, postData);‍‍‍‍

Hi,

I know it's a bit late but… Have you tried using the requestBody object?

As in requestbody.content

Check this page http://wiki.alfresco.com/wiki/Web_Scripts#Request_Processing

Hope that helps.

In order to use args, you must post a formdata. This can be done either with a form or with:

function getXhr(){
   var xhr = null; 
   if(window.XMLHttpRequest)
      xhr = new XMLHttpRequest(); 
   else if(window.ActiveXObject){
      try {
         xhr = new ActiveXObject("Msxml2.XMLHTTP");
      } catch (e) {
         xhr = new ActiveXObject("Microsoft.XMLHTTP");
      }
   } else {
      alert("${message('templates.apmSearch.get.error.XMLHTTP')}"); 
      xhr = false; 
   } 
   return xhr;
}

var url = Alfresco.constants.PROXY_URI + "folder-search";
var xhr = getXhr();
xhr.open("POST",url,false);
var data = new FormData();
data.append("searchTxt", document.getElementById("jtf_text").value);
xhr.send(data);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

but formdata object is not supported by ie (don't remember which versions) so there are some more obscure ways:

Or you can POST that as a json. Ie. from Share (or wherever) use the YUI ajax request:

Alfresco.util.Ajax.request({
  url: webscriptUrl,
  method: POST,
  requestContentType: "application/json",
 … // other params
‍‍‍‍‍‍

Then you can get the json object in your webscript, like this:

var param1 = json.get("param1");‍
