How to upload a file on https site with cookies using new httpClient ?

Hello,

I have a script in Java to upload a file to a https site with cookie context. My question : is it possible to do the same instructions with the new object HttpClient in PB ? I have put in attachment the java script that works. Thanks for your help.

here is what i need equivalence in PB :

   private CloseableHttpClient httpClient = HttpClients.createDefault();

   private CookieStore cookieStore = new BasicCookieStore();//Will store the session cookie
   private HttpClientContext locContext = HttpClientContext.create();//Will contain the cookieStore

public int getConnection() throws ClientProtocolException, IOException {

        HttpPost httpPost = new HttpPost(getUrl().concat("/j_spring_security_check"));


   httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
   httpPost.setHeader("Connection", "keep-alive");
   List params = new ArrayList();
   params.add(new BasicNameValuePair("status", "A"));
   params.add(new BasicNameValuePair("j_username", "xxxxxxx"));
   params.add(new BasicNameValuePair("j_password", "yyyyyyy"));
   params.add(new BasicNameValuePair("enabled", "true"));
   httpPost.setEntity(new UrlEncodedFormEntity(params));

   locContext.setCookieStore(cookieStore);

   HttpResponse response = httpClient.execute(httpPost, locContext);

   return response.getStatusLine().getStatusCode();

public void uploadFile() throws ClientProtocolException, IOException {
   HttpPost uploadFile = new HttpPost(getUrl().concat("/protected/jwimportdeliveries/uploadDeliveries.do"));

   MultipartEntityBuilder builder = MultipartEntityBuilder.create();
   builder.addTextBody("location", "C:/local/", ContentType.TEXT_PLAIN);

   // File f = new File("C:\\Local\\Mozaik_JLB_20190124.xlsx");
//        Lire_Ini file_ini = new Lire_Ini();
        String file_Moza = file_ini.get_file("FILE_MOZAIK");
        File f = new File(file_Moza);
   builder.addBinaryBody("File", new FileInputStream(f), ContentType.APPLICATION_OCTET_STREAM, f.getName());

   HttpEntity multipart = builder.build();
   uploadFile.setEntity(multipart);

   HttpResponse response = httpClient.execute(uploadFile, locContext);

   String responseString = EntityUtils.toString(response.getEntity(), "UTF-8");

Hi Chris, this is a veeeery late comment, but just to point out: you can also use FileReadEx() to read "chunks" of data. The advantage it has, is that you can read BIG chunks, but small enough to get into trouble with the PBVM app storage. (Let's say 100MB chunks should be fine).

correction: "small enough to NOT get into trouble..."
