Plugin samples

Basics

Suggested code sample

First, you must create the webservice object:

OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

Then should login using the method "login". You can access the "login" method from webservice object "ws" as is shown below:

ws.login(user, password);

Once you are logged with the webservices the session is keep in the webservice Object. Then you can use the other API method

At this point you can use all the Plugin methods from "plugin" class as is shown below:

ws.plugin.executePluginPost("com.openkm.plugin.rest.TestRestPlugin", parameters, String.class, null);

Methods

executePluginPost

Description:

MethodReturn valuesDescription

executePluginPost(String className, Map<String, String> parameters, Class<?> clazz, InputStream is)

Object

Return the Object value of execution of a class which implements RestPlugin.
  • The "className" value must be the canonical class name of a class which implements RestPlugin interface.
  • The "parameters" map are values what will be used by class set in className.
  • The "clazz" value should be the Class class of the returned object. It's used by REST for unmarshalling the result of the query.
  • The "is" stream allow to uploading a document.

This method execute a REST call at POST.

Example:

package com.openkm;

import java.util.HashMap;
import java.util.Map;

import com.openkm.sdk4j.OKMWebservicesFactory;
import com.openkm.sdk4j.impl.OKMWebservices;

public class Test {

    public static void main(String[] args) {
        String host = "http://localhost:8080/openkm";
        String user = "okmAdmin";
        String password = "admin";
        OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

        try {
            ws.login(user, password);
            Map<String, String> parameters = new HashMap<>();
            parameters.put("param1", "value1");
            parameters.put("param2", "value2");
            String value = (String) ws.plugin.executePluginPost("com.openkm.plugin.rest.TestRestPlugin", parameters, String.class, null);
            System.out.println(value);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

executePostPluginReturnFile

Description:

MethodReturn valuesDescription

executePluginPostReturnFile(String className, Map<String, String> parameters, InputStream is)

InputStream

Return an InputStream of execution of a class which implements RestPlugin.
  • The "className" value must be the canonical class name of a class which implements RestPlugin interface.
  • The "parameters" map are values what will be used by class set in className.
  • The "is" stream allow to uploading a document.

This method execute a REST call at POST.

The RestPlugin must return a Response object. Take a look at the next sample implementation of the RestPlugin:

package com.openkm.plugin.rest;

import net.xeoh.plugins.base.annotations.PluginImplementation;

import java.io.InputStream;
import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.InputStreamResource;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;

import com.openkm.bean.Document;
import com.openkm.module.db.DbDocumentModule;
import com.openkm.plugin.BasePlugin;
import com.openkm.util.PathUtils;

/**

 */
@PluginImplementation
public class TestGetDocumentRestPlugin extends BasePlugin implements RestPlugin {

    private static Logger log = LoggerFactory.getLogger(TestGetDocumentRestPlugin.class);

    @Autowired
    private DbDocumentModule dbDocumentModule;

    @Autowired
    private PathUtils pathUtils;

    @Override
    public Object executePlugin(Map<String, String> parameters, InputStream is) throws Exception {
        log.debug("executePlugin({})", parameters);
        String docId = parameters.get("docId");
        boolean inline = parameters.containsKey("inline");
        Document doc = dbDocumentModule.getProperties(null, docId);
        String mimeType = doc.getMimeType();
        String fileName = pathUtils.getName(doc.getPath());
        InputStream isContent = dbDocumentModule.getContent(null, docId, false);

        HttpHeaders responseHeaders = new HttpHeaders();
        responseHeaders.add("Content-Type", mimeType);

        // inline true when you want to embedded the content into
        if (inline) {
            responseHeaders.add("Content-disposition", "inline; filename=\"" + fileName + "\"");
        } else {
            responseHeaders.add("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
        }

        responseHeaders.setContentLength(doc.getActualVersion().getSize());
        InputStreamResource inputStreamResource = new InputStreamResource(isContent);
        log.debug("TestGetDocumentRestPlugin: [BINARY]");
        return new ResponseEntity<>(inputStreamResource, responseHeaders, HttpStatus.OK);
    }
}

Example:

package com.openkm;

import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.HashMap;
import java.util.Map;

import org.apache.commons.io.IOUtils;

import com.openkm.sdk4j.OKMWebservicesFactory;

public class Test {

        String host = "http://localhost:8080/openkm";
        String user = "okmAdmin";
        String password = "admin";
        OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

        try {
            ws.login(user, password);
            Map<String, String> parameters = new HashMap<>();
            parameters.put("docId", "/okm:root/invoices/00000001_001_of_001.pdf");
            InputStream is = ws.plugin.executePluginPostReturnFile("com.openkm.plugin.rest.TestGetDocumentRestPlugin", parameters, null);
            OutputStream fos = new FileOutputStream("/home/user/Desktop/test.pdf");
            IOUtils.copy(is, fos);
            IOUtils.closeQuietly(is);
            IOUtils.closeQuietly(fos);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

            parameters.put("docId2", "/okm:root/invoices/00000001_001_of_001.pdf2");
            String value = (String) ws.plugin.executePluginGet("com.openkm.plugin.rest.TestRestPlugin", parameters, String.class);
            System.out.println(value);
        } catch (Exception e) {
