Issue in creating blog using REST API

[pradeepsimha]

Hi,

I am trying to create blog post programmatically using REST API, the url is like below:

/alfresco/service/api/blog/site/{site}/{container}/posts‍

When I post the URL I am getting below exception:

{    "status": {        "code": 500,        "name": "Internal Error",        "description": "An error inside the HTTP server which prevented it from fulfilling the request."    },    "message": "04060020 Wrapped Exception (with status template): null",    "exception": "org.springframework.extensions.webscripts.WebScriptException - 04060020 Wrapped Exception (with status template): null",    "callstack": [        "",        "java.lang.NullPointerException",        "org.alfresco.repo.web.scripts.blogs.posts.BlogPostsPost.parsePostParams(BlogPostsPost.java:95)",        "org.alfresco.repo.web.scripts.blogs.posts.BlogPostsPost.executeImpl(BlogPostsPost.java:72)",        "org.alfresco.repo.web.scripts.blogs.AbstractBlogWebScript.executeImpl(AbstractBlogWebScript.java:294)",        "org.springframework.extensions.webscripts.DeclarativeWebScript.execute(DeclarativeWebScript.java:64)",        "org.alfresco.repo.web.scripts.RepositoryContainer$3.execute(RepositoryContainer.java:429)",        "org.alfresco.repo.transaction.RetryingTransactionHelper.doInTransaction(RetryingTransactionHelper.java:450)",        "org.alfresco.repo.web.scripts.RepositoryContainer.transactionedExecute(RepositoryContainer.java:491)",        "org.alfresco.repo.web.scripts.RepositoryContainer.transactionedExecuteAs(RepositoryContainer.java:529)",        "org.alfresco.repo.web.scripts.RepositoryContainer.executeScript(RepositoryContainer.java:341)",        "org.springframework.extensions.webscripts.AbstractRuntime.executeScript(AbstractRuntime.java:378)",        "org.springframework.extensions.webscripts.AbstractRuntime.executeScript(AbstractRuntime.java:209)",        "org.springframework.extensions.webscripts.servlet.WebScriptServlet.service(WebScriptServlet.java:132)",        "javax.servlet.http.HttpServlet.service(HttpServlet.java:727)",‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I tried to add parameters like title, content etc. But still I get the same error. My question is, what is the correct syntax for creating blog post using REST API? This URL: http://docs.alfresco.com/4.1/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Freferences%2FRESTful-i... doesn't explain in brief what all the parameters I need to pass. Can anyone kindly guide me in this?

Nearly all parameter is nullable ,but make sure set content type to application/json.

      HttpClient client = new HttpClient();      client.getState().setCredentials(            new AuthScope("localhost", 8080, "Alfresco"),            new UsernamePasswordCredentials("admin", "admin"));      String site = "kaynezhang";      String container = "blog";      String apiurl = "http://localhost:8080/alfresco/service/api/blog/site/'+ site + "/" + container + "/posts";      PostMethod post = new PostMethod(apiurl);      try {         JSONObject blog = new JSONObject();         blog.put("title", "title");         blog.put("content", "content");         JSONArray arr = new JSONArray();         arr.put("tag1");         arr.put("tag2");         blog.put("tags", arr);         blog.put("draft", false);         post.setDoAuthentication(true);         post.setRequestHeader("Content-Type", "application/json");// make sure set content type to application/json         post.setRequestEntity(new StringRequestEntity(blog.toString(),"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();      }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
