org.apache.http.client.methods.HttpPost - creating a customized type

dmralfing — Wed, 22 Jan 2014 15:52:05 GMT

I´m trying to create a customized document instance of my model type "prs:mydocument" using the Alfresco Java API. I´m trying it with the library: org.apache.http.client.methods.HttpPostSomebody knows what´s exactly the script I need?. I was trying with the script "/share/proxy/alfresco/slingsho

I'm not very sure what you mean.
Do you mean to create a document node with type prs:mydocument" using webscript api ?
Then you can use


 POST  /api/node/{store_type}/{store_id}/{id}/children
 POST  /api/path/{store_type}/{store_id}/{nodepath}/children
‍‍‍‍

you can't use activity webscript api ,It will only create an activity with specified type.

Ok, but can I find somewhere in the web any example with real values - not descriptions - or at least the range of values that can have any parameter?. I´m trying, but I don´t get it!

Following is sample code I used to test custom type.


package com.kayne.cmis.webscript;

import java.io.File;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.UsernamePasswordCredentials;
import org.apache.commons.httpclient.auth.AuthScope;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.StringRequestEntity;
import org.apache.commons.io.FileUtils;
public class CMISTest {
   
   private void testAddNode(){
      HttpClient client = new HttpClient();
      client.getState().setCredentials(
            new AuthScope("localhost", 8080, "Alfresco"),
            new UsernamePasswordCredentials("admin", "admin"));

      String apiurl = "http://localhost:8080/alfresco/service/api/path/workspace/SpacesStore/Company%20Home/TESTFOLDER1/children?format=atomentry";
                                                          
      PostMethod post = new PostMethod(apiurl);
      try {
         String test = FileUtils.readFileToString(new File("E:\\KayneZhang\\test2.xml"));
         System.out.println(test);
         post.setDoAuthentication(true);
         post.setRequestHeader("Content-Type", "application/atom+xml");
         post.setRequestEntity(new StringRequestEntity(test,
               "application/json", "UTF-8"));

         int status = client.executeMethod(post);
         if (status != HttpStatus.SC_OK) {
            System.err.println("Method failed: " + post.getStatusLine());
         }
         String resultString = post.getResponseBodyAsString();
         System.out.println(resultString);
      } catch (Exception e) {
         e.printStackTrace();
      } finally {
         post.releaseConnection();
      }
   }
   public static void main(String[] args) {
      CMISTest test = new CMISTest();
      test.testAddNode();
   }
}

Ok, but where do you indicate that the content that you want to create is "prs:mydocument" and not "cm:content" neither "cm:folder"?. I´m not sure if is the right script, all that I want is so easy: to create a customized content type with a web script!. I have tried executing this webscript also
/share/proxy/alfresco/api/type/prs%3amydocument/formprocessor
…but is doesn´t work..
It must exist any webscript, I don´t know if it is the one you tell me..

The xml file you sent to webscript url "http://localhost:8080/alfresco/service/cmis/p/TESTFOLDER1/children?format=atomentry" contains all node information ,include node(document) type ,properties and so on.

In my example code test2.xml following section contains node type (my custom type is ca:customContent,for yours you should use prs:mydocument). 😧 means ca:customContent is subtype of cm:cotent.


         <cmis:propertyId propertyDefinitionId="cmis:objectTypeId">

            <cmis:value>D:ca:customContent</cmis:value>

         </cmis:propertyId>
‍‍‍‍‍‍‍

Following section contains sample code of a custom property named ca:anotherText2 that belong to custom type ca:customContent,in your case you should use your custom property instead.


         <cmis:propertyString propertyDefinitionId="ca:anotherText2" displayName="ca:anotherText2" queryName="ca:anotherText2">
            <cmis:value>another text</cmis:value>
         </cmis:propertyString>

Thank you Kaynezhand, you are right, but it doesn´t include any file in the code you have put. I could
create a customized type with a function like this:


public static synchronized void testPost (String strName,String strPath) throws Exception
{
    String url="http://localhost:8080/share/proxy/alfresco/api/type/prs%3amydocument/formprocessor";
    String param="{";
    param+="\"alf_destination\":\"workspace://SpacesStore/2198ff48-de64-4800-98c9-389136439153\",";
    param+=",\"prop_cm_name\":\"HELLO MY NEW DOCUMENT\"";
    param+=",\"prop_prs_department\":\"CORPORATIVE FINANCE\"";
    param+="}";
    org.apache.http.impl.client.DefaultHttpClient client = new org.apache.http.impl.client.DefaultHttpClient();
    client.setCookieStore(cookieStore);
    org.apache.http.client.methods.HttpPost post = new org.apache.http.client.methods.HttpPost(url);
    post.setHeader("Content-Type", "application/json");
    post.setEntity(new StringEntity(param,"UTF-8"));
   org.apache.http.client.ResponseHandler<String> responseHandler = new org.apache.http.impl.client.BasicResponseHandler();
    client.execute(post, responseHandler);
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I prefer it because it´s easier, but I don´t mind to do it with CMIS as you say if it exists any way
to upload also the file content. It should me something like this, but it doesn´t work..


   File f=new File ("D:/temp/mydocument.pdf");
   post.setEntity (new FileEntity (f, "application/pdf"));
‍‍‍‍

How I create my customized content including also the file?

Re: org.apache.http.client.methods.HttpPost - creating a customized type

kaynezhang — Fri, 24 Jan 2014 17:54:02 GMT

NO,I already include a txt file in my code .
Please check this section


<cmisra:content>
<cmisra:mediatype>text/plain</cmisra:mediatype>
<cmisra:base64>VGhlIHF1aWNrIGJyb3duIGZveCBqdW1wcyBvdmVyIHRoZSBsYXp5IGRvZy4=</cmisra:base64>
</cmisra:content>
‍‍‍‍‍‍

It is used to upload a file(content),in my case I upload a file whose format is a text/plain(indicated by <strong> cmisra:mediatype</strong> element) and whose content is The quick brown fox jumps over the lazy dog.(indicated by <strong> cmisra:base64</strong> element,base64 encoded of course).

In cmis atom binding if you want to upload a file ,it must be encoded using base64 encoder.

Dear Kaynezhang, can you please suggest a URL entry for upload to my.alfresco.com cloud site/documentLibrary

for on-premises storage as you told entry is:

http://localhost:8080/alfresco/service/api/path/workspace/SpacesStore/Company%20Home/TESTFOLDER1/children?format=atomentry‍

but for cloud this does not work. There should be company name, account name, and site name I'm guessing.

thanks,
