Liferay 6.1 jsonws example

Liferay Legend Postagens: 1399 Data de Entrada: 17/09/10 Postagens Recentes
In my blog post from last June, I gave 3 examples of using Liferay's built-in JSON web services to query and post new content to Liferay. It was based on 6.0, and a couple of you noticed that it doesn't work in 6.1, so I re-did the 3rd example to demonstrate how to achieve the same thing using 6.1's new jsonws services. Below you will find the addArticle() and removeArticle() from the 3rd example of my blog post, re-written to work with Liferay 6.1 GA1.



	private static void addArticle() throws Exception {
		HttpHost targetHost = new HttpHost("localhost", 8080, "http");
		DefaultHttpClient httpclient = new DefaultHttpClient();
		httpclient.getCredentialsProvider().setCredentials(
			new AuthScope(targetHost.getHostName(), targetHost.getPort()),
			new UsernamePasswordCredentials("bruno@7cogs.com", "bruno"));

		// Create AuthCache instance
		AuthCache authCache = new BasicAuthCache();
		// Generate BASIC scheme object and add it to the local
		// auth cache
		BasicScheme basicAuth = new BasicScheme();
		authCache.put(targetHost, basicAuth);

		// Add AuthCache to the execution context
		BasicHttpContext ctx = new BasicHttpContext();
		ctx.setAttribute(ClientContext.AUTH_CACHE, authCache);

		HttpPost post = new HttpPost("/api/secure/jsonws/journalarticle/add-article");
		Calendar yesterday = Calendar.getInstance();
		yesterday.add(Calendar.DAY_OF_YEAR, -1);
		Calendar nextWeek = Calendar.getInstance();
		nextWeek.add(Calendar.WEEK_OF_YEAR, 1);

You will notice a couple of changes:

  • The path to the jsonws resource has changed (no longer need tunnel-web). It is now /api/secure/jsonws/<service>/<method>. You can read more about these services in the official development documentation.
  • There are a couple of new parameters needed for addArticle(), and they are of type java.util.Map - these can be passed by forming a serialized representation of the map using json notation. e.g. {"en_US":"Some Title in US English"}
  • There are also new parameters for classNameID, classPK, and layoutId - all can be set to 0 when creating a new article. These new parameters are used for storing default values for content (see LPS-16960) and for setting the default display page (see LPS-15035).

Similar changes are needed to make the other 2 examples work, but they should be straightforward based on the example above.

Enjoy!

Hi James:
I have JSON services working in 6.1 but it's not secured. I can access my test service using url http://localhost:8080/DataSourceTest-portlet/api/secure/jsonws/training/get-my-training/myparam/myparamvalue

Only problem is I can not secure access using user id and pass. What does this mean when we have api/secure/jsonws in the url?

Thanks.

Check the following security patch.

Doesn't work with 6.1 EE

Pass value 0 to classNameId parameter.
I get the following exception
com.liferay.portal.NoSuchGroupException: No Group exists with the primary key 0
So I changed classNameId to a positive value.
The article gets added but is not being displayed in the liferay webcontent list.
I had to manually update the classNameId to 0 in JournalArticle table in the DB for the newly added article to appear in the web content list

Please reply

I'm getting the same Error with LR 6.1.1 CE GA2. I already tried to submit a serviceContext with the scopeGroupId, but it's still the same error. Is there no possible solution?

Hi Karthik, J W

I have debugged the code and following are my findings -

com.liferay.portal.NoSuchGroupException: No Group exists with the primary key 0


Above exception has nothing to do with classNameId parameter; Its because of following code in the JournalArticleWorkflowHandler class


ServiceContext serviceContext = (ServiceContext)workflowContext.get(
			"serviceContext");

		String articleURL = PortalUtil.getControlPanelFullURL(
			serviceContext.getScopeGroupId(), PortletKeys.JOURNAL, null);


Here serviceContext.getScopeGroupId() returns 0 that results in com.liferay.portal.NoSuchGroupException exception in PortalImpl class


	public String getControlPanelFullURL(
			long scopeGroupId, String ppid, Map<string, string[]> params)
		throws PortalException, SystemException {

		StringBundler sb = new StringBundler(6);

		Group group = GroupLocalServiceUtil.getGroup(scopeGroupId); // at this line
</string,>


When we pass classNameId parameter a value >0 then this flow is bypassed so we do not get this exceprion.


if (classNameId == 0) {
			WorkflowHandlerRegistryUtil.startWorkflowInstance(
				user.getCompanyId(), groupId, userId,
				JournalArticle.class.getName(), article.getId(), article,
				serviceContext);

			if (serviceContext.getWorkflowAction() !=
					WorkflowConstants.ACTION_PUBLISH) {

				// Indexer

				Indexer indexer = IndexerRegistryUtil.getIndexer(
					JournalArticle.class);

				indexer.reindex(article);
			}
		}
		else {
			updateStatus(
				userId, article, WorkflowConstants.STATUS_APPROVED, null,
				serviceContext);
		}

To get this fixed pass scopeGroupId within serviceContext -

 params.add(new BasicNameValuePair("serviceContext.scopeGroupId", "10180"));

Hi Haris,
where can I find scopeGroupId in lportal database?

I have the same problem with Liferay 6.2.

Hi

first of all thanks for your post,
I was try your sample 1) and after adapting is working fine. But I want to invoke a service (DLFileEntry or DLApp) and in both cases i get the same error:

I was able to create a DlFileEntry , with the following code: But it works only with empty “bytes” you get a record create but with a cero bytes, I try many diferents ways to convert the bytes into Json string, but any works I always get the error:

{"exception":"Unable to convert to type: [B\njodd.typeconverter.TypeConversionException: Unable to convert value: JVBERi0xLjQKJeLjz9MKNSAwIG9iago8


what is the correct way to fill up that param “bytes” in a /dlapp/add-file-entry

Here is the code I was trying :

	public static void main(String[] args) throws Exception {
		long folderId =  13713;
		long groupId = 10179;

		File file = new File("temp"+"sourceFileName");
		String url = "http://localhost:8080/pdfs/ACTANum126.pdf";
		System.err.println("URL A conectar" +  url);
		URLConnection conn;
		try {
			conn = new URL(url).openConnection();

		conn.connect();
		InputStream is = conn.getInputStream();
		byte[] bytes = IOUtils.toByteArray(is);


		Base64 base64 = new Base64();
		byte[] buffer = new byte[(int) file.length() + 100];
		int length = is.read(buffer);
		String sTRBytes = Base64.encodeBase64URLSafeString(bytes);
//		String sTRBytes = JsonWriter.objectToJson(bytes);
//		String sTRBytes = JsonWriter.toJson(bytes);

		is.close();
		addDLFileEntry(sTRgroupId, sTRfolderId , "titlessaasss", "description", sTRfileEntryTypeId , sTRfile, sTRis , sTRsize, sTRscopeGroupId, mimeType,sTRBytes );

public static void addDLFileEntry(String groupId, String folderId, String title, String description, String fileEntryTypeId, String file, String is, String size, String scopeGroupId, String mimeType,String sTRBytes) throws Exception {
	
	
	HttpHost targetHost = new HttpHost("localhost",8080,"http");

Finally I found the solution:

what the param need is just a list of values that represents the data by example : 23,34,35,12….
as String sTRBytes = JsonWriter.objectToJson(bytes); returns

{"@type":"B","@items”:[23,34,35,12…..]}

you just have to take off what is not need

sTRBytes = sTRBytes.substring(24,sTRBytes.length()-2);

(or any other way to get the content of a Byte[] as a string of a list of numbers)

then with :
params.add(new BasicNameValuePair("bytes", sTRBytes));
you will your data upload a attached to the DLFileEntry Row

Hi

I created a JSON Webservice in liferay without authentication.

I build a simple java client that access with that GET call:




    URLConnection conn = null;
   try {
      conn = url.openConnection ();
   } catch (IOException e) {
		e.printStackTrace();
   }
   BufferedReader rd = null;
   try {
	rd = new BufferedReader(new InputStreamReader(conn.getInputStream(),Charset.forName("UTF-8")));
   } catch (IOException e) {
	e.printStackTrace();
  }

    StringBuffer sb = new StringBuffer();
    String line;
     try {
		while ((line = rd.readLine()) != null) {sb.append(line);	}
    } catch (IOException e) {
               e.printStackTrace();
    }


Then I mount JSONObject with response obtained. It's a simple http get call.

My problem is encoding. By default I received with ISO-8859-1. I changed the InputStreamReader call , with charset UTF-8 but does not works. The special chars are broken by thuis way.

Any help please?

Hi James,

We are trying to create announcement through json service using httpClient in Liferay 6.1.

JSON URL: http://localhost:8080/api/secure/jsonws/announcements/add-entry We got below exception

has you send all the params that the JSON Service needs?

you can see in http://localhost:8080/api/jsonws?signature=/announcementsentry/add-entry-19-plid-classNameId-classPK-title-content-url-type-displayDateMonth-displayDateDay-displayDateYear-displayDateHour-displayDateMinute-expirationDateMonth-expirationDateDay-expirationDateYear-expirationDateHour-expirationDateMinute-priority-alert

If you don’t fill that params, then you get the error :

I have similar problem with /api/secure/jsonws/dlfileentry/add-file-entry and wasn’t able to resolve it even I was sending all the params, I was getting the same error:
finally I used /api/secure/jsonws/dlapp/add-file-entry and then it works,
I don’t know If exists equivalent for announcementsentry, I didn’t found,

Any way I don’t see any mistake in your code and after my case where I was double checking my params, and I was getting always the error , my conclusion is that the JSON service is wrong documented, in your case and also in my case, I hope that somebody from Liferay develoment team clarify this point.

Please If you finally found the solution post it here.

I had similar error messages and it was solved by using hints on the JSON calls, that helps the web-server to match the correct method

for example, the below JSON call is working,
using a hint = 10
(I am using "api/secure/jsonws/invoke ", Liferay 6.1 GA2)



    JSONObject _command = new JSONObject();
    	JSONObject serviceContext = new JSONObject();
JSONArray files = new JSONArray();

        try {

            JSONObject _params = new JSONObject();
            _params.put("groupId", GROUP_ID);
            _params.put("categoryId", CATEGORY_ID);
            _params.put("subject", "test 15");
            _params.put("body", "test 15");
            _params.put("format", "bbcode");
            _params.put("inputStreamOvPs", files);
            _params.put("anonymous", false);
            _params.put("priority", 0);
            _params.put("allowPingbacks", false);
            _params.put("serviceContext", serviceContext);
            _params.put("serviceContext.addGroupPermissions", true);
            _params.put("serviceContext.assetTagNames", "vegetables, water");
            _command.put("/mbmessage/add-message.10", _params);

Well, I figured out that exception. I didn't have my content wrapped in XML.

Now I am getting the following...any thoughts?

"No DDMStructure exists with the key {groupId=10197, classNameId=10109, structureKey=0}"

I am getting the same error. I am using the /api/jsonws/invoke

"No DDMStructure exists with the key {groupId=10197, classNameId=10109, structureKey=11680}"

Any help and pointers is greatly appreciated.
