call my web script

[dmralfing]

I have implemented a web script that works OK. It works fine writting this in the browser:
    http://localhost:8080/alfresco/service/demo/readonly/prueba
But I want to call it from a java program. The program is:

import java.io.IOException;import java.io.InputStream;import java.net.HttpURLConnection;import java.net.URL;import java.util.ArrayList;import java.util.List;import org.apache.commons.io.IOUtils;import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.NameValuePair;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.CookieStore;import org.apache.http.client.ResponseHandler;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpGet;import org.apache.http.client.methods.HttpPost;import org.apache.http.entity.StringEntity;import org.apache.http.impl.client.BasicResponseHandler;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.message.BasicNameValuePair;import org.json.JSONArray;import org.json.JSONObject;   public static void test (String hostname, String port, String user, String password) throws Exception   {      try      {         URL_BASE="http://'+hostname+':'+port;         DefaultHttpClient client = new DefaultHttpClient();         HttpPost post = new HttpPost(URL_BASE+"/share/page/dologin");         List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);         nameValuePairs.add(new BasicNameValuePair("username", user));         nameValuePairs.add(new BasicNameValuePair("password", password));         post.setEntity(new UrlEncodedFormEntity(nameValuePairs));         client.execute(post);         setCookieStore(client.getCookieStore());         executeGET (client.getCookieStore(),"http://localhost:8080/alfresco/service/demo/readonly/prueba");      }      catch (Exception ex)      {         throw new Exception ("No se pudo realizar la conexión al servidor \""+hostname+ "\" por el puerto "+port+" con el usuario y password indicados.");      }         }//connectprivate static String executeGET (CookieStore cookieStore, String url) throws Exception     {            System.out.println(url);      if (cookieStore==null)            throw new Exception("ERR. Cookie Store NULO");      String result=null;        InputStream instream=null;        try        {            DefaultHttpClient client = new DefaultHttpClient();            client.setCookieStore(cookieStore);            HttpGet  httpget = new HttpGet(url);            HttpResponse  response = client.execute(httpget);            HttpEntity entity = response.getEntity();            if (entity==null) throw new Exception("ERROR. El objeto entity es nulo");                instream = entity.getContent();                result = IOUtils.toString(instream);                System.out.println(result);                        }//try         catch (ClientProtocolException ex){ex.printStackTrace();}         catch (IOException ex){ex.printStackTrace();}         catch (Exception ex){ex.printStackTrace();}         finally{ if (instream!=null) instream.close();}         return result;   }//execute‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Somebody knows what do I´m doing wrong?

What is your error?
Following is an example of call GetMethod you can refer to

      HttpClient client = new HttpClient();      client.getState().setCredentials(            new AuthScope("localhost", 8080, "Alfresco"),            new UsernamePasswordCredentials("admin", "admin"));      String uid = "1565a32e-7863-45af-a9fa-b68ad206b5e7";      String apiurl = "http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/'+uid+'/versions";      GetMethod get = new GetMethod(apiurl);      try {         get.setDoAuthentication(true);         get.setRequestHeader("Content-Type", "application/json");            int status = client.executeMethod(get);         if (status != HttpStatus.SC_OK) {            System.err.println("Method failed: " + get.getStatusLine());         }         String resultString = get.getResponseBodyAsString();         System.out.println(resultString);               } catch (Exception e) {         e.printStackTrace();      } finally {         get.releaseConnection();      }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Ok, it works fine doing it with your function. Do you know also how can I adapt the Web Script to let him be called through "/share/proxy"?,
For example: http://localhost:8080//share/proxy/…

[kaynezhang]

I'm sorry ,what do you mean by "adapt the Web Script to let him be called through "/share/proxy""? could you restate it?

[dmralfing]

For example, if I want to call my web script I have to do:
    "http://localhost:8080/alfresco/service/demo/readonly/prueba"
But I have seen in a lot of examples that you can call the same webscript doing something like this:
      "http://localhost:8080/share/proxy/alfresco/service/demo/readonly/prueba"
   I need it because I´m using a Web Script allocated in my Alfresco that I call since the Share, so if I don´t do it like that, the system force to authenticate again due to the connection to Alfresco since the Share, and I'd rather to avoid it. I guess that if I call the web script with "share/proxy" it won´t be necessary that authentication..

[kaynezhang]

If you are calling alfresco web script api  from share using script js , you can use remote object.
If you are calling alfresco web script api from share usring java ,you can use ScriptRemote

        ScriptRemote scriptRemote = serviceRegistry.getScriptRemote();        Response response = scriptRemote.connect().get(uri);‍‍‍‍

The problem is that I use Ajax in my Share to load data values in some combos.
Being queries, Alfresco repository must be acceses so  it makes me authenticate again,
and what I want is to avoid it.
Wathing my code you will understand better, it is:

var urlService3= window.location.protocol + '//' + window.location.host + '/alfresco/service/com/portales/intranet/combos/tipos/listado';      $.ajax({        type: "GET",        url: urlService3,        contentType: "application/json; charset=utf-8",        dataType: "json",        success: function(response3) {            var results3 = response3;                                               $( "select[name='prop_prtls_tipo_documento']" ).html("");            for(var i=0;i<results3.length;i++){                                                                                                                              $( "select[name='prop_prtls_tipo_documento']" ).append("<option value='"+results3.valor+"'>"+results3.valor+"</option>");                                               }                                                     },        error: function(xhr, status, error) {            var errorMessage = error.description != null ? error.description : error;                                                                                              $( "select[name='prop_prtls_tipo_documento']" ).html("<option value='"+errorMessage+"'>"+urlService3+"_"+errorMessage+"</option>");        }    });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

[kaynezhang]

You can call Alfresco webscript api using client-side javascript from share like below code :

Alfresco.util.Ajax.request({   url: Alfresco.constants.PROXY_URI + urlService3,   method: Alfresco.util.Ajax.GET (if you want to use post method ,please use  Alfresco.util.Ajax.POST)   dataObj:   {                   data1: "data1",                submitType: "json"   },   successCallback:   {      fn: this.success, // success callback method       scope: this   },   failureCallback:   {      fn: this.failure, // failure callback method       scope: this   }});‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Can you try making ajax call using Alfresco.util.Ajax.request? Also, if you are already logged into alfresco share and invoking repository webscripts then it should not again ask for authentication.
