Posting a file: .NET calling a WebScript:

eg — Thu, 21 Feb 2008 17:29:35 GMT

I am trying to post a file to alfresco by calling a web script from a .net application. I have tested the webscript by calling it from a html form that posts the file and it works fine. When I try it from the .net app the formdata.fields collection always contains 0 items. The main .net code is show

I'd suggest sniffing the request for both the html form submission and your programmatic submission. I suspect the programmatic one isn't correct.

Just to add to David's comment, you might find the free Microsoft tool Fiddler2 useful for sniffing the HTTP traffic.

Get it from http://www.fiddler2.com/

We got .net to successfully call the upload web script. We ended up using a combination of query string parameters to send the indexing values and a post for the file itself.

The code is shown below:

.NET Code

WebClient w = new WebClient();
w.Credentials = new NetworkCredential("admin", "admin");

w.QueryString.Add("occno", "556677");
w.QueryString.Add("docid", "321");
w.QueryString.Add("occdate", DateTime.Now.ToShortDateString());
w.QueryString.Add("docdate", DateTime.Now.ToShortDateString());
w.QueryString.Add("claimno", "1");
w.QueryString.Add("docname", "DocumentInventory.doc");
w.QueryString.Add("source", "TEST");
w.QueryString.Add("location", "G360 Backfile");

w.UploadFile("http://tw6-vm1:8080/alfresco/service/cdi/Upload", "POST", @"C:\DocumentInventory.doc");‍‍‍‍‍‍‍‍‍‍‍‍‍

The web script code:

function initRequest()
{

    var oRequest = new alfAddRequest();


   addItem(oRequest, 'occno');
   addItem(oRequest, 'claimno');
   addItem(oRequest, 'docname');
   addItem(oRequest, 'docdate');
   addItem(oRequest, 'docid');
   addItem(oRequest, 'source');
   addItem(oRequest, 'location');
   addItem(oRequest, 'occdate');
   
   addFile(oRequest);

   
     return oRequest;

}

function addItem(objDest, strItemName) {
   if(args[strItemName] != null) {
      eval('objDest.' + strItemName + ' = args[strItemName];');
   }
   else {
      for each(field in formdata.fields) {
         if(field.name == strItemName) {
            eval('objDest.' + strItemName + ' = field.value');
            break;
         }
      }
   }
}

function addFile(objDest) {
   //Only adds the first file found!
   //Could be modified to add multiple files

   for each (field in formdata.fields) {
      if(field.isFile) {
         objDest.filename = field.filename;
         objDest.content = field.content;
         break;
      }
   }
         
}
