Error while calling wcm asset creation URI

[darklord]

Hi,

I am simply trying to call the wcm rest call to create a new asset under my sandbox. My code is throwing 500 ERROR and console is showing error that required parameter 'assest' is not defined. Below is the code and error I am seeing. Thanks for any help…

                         HttpClient client = new HttpClient();
         
         
         String asset = "'{ name:\"specialfile.txt\",type:\"file\",content:\"this is a sample text file\" }'";
         
         String URL = "http://localhost:8080/alfresco/service/api/wcm/webprojects/myproject/sandboxes/myproject--admin/asse...";
         
               PostMethod post = new PostMethod(URL);
         NameValuePair[] data = {new NameValuePair("asset", asset)};
            
         client.getState().setCredentials(
                   new AuthScope("localhost", 8080, null),
                   new UsernamePasswordCredentials("admin", "admin")
                   );
         post.setRequestBody(data);
         int statusCode1 = client.executeMethod(post);
         ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And this is the exception i see in the tomcat logs…

[mrogers]

A JSON property called "asset" is not required. 

That script just takes, properties called name, type and (optionally) content.

[darklord]

Hi Rogers,

Thanks for your reply. I was able to fix the issue with the following change:

asset need to be passed not in requestbody but requestheader. Also the content type need to be defined  as application/json as follows:

post.setRequestHeader("asset", asset);
post.setRequestHeader("Content-Type", "application/json");

But now I see another exception in the logs saying:

[darklord]

Considering your thought of not setting asset in request, do I need to set properties name, type and content in request ?

I believe the input should be in json format. Is this not the case?

Thanks.

[mrogers]

There should be a json object in the body of your request.

[darklord]

Yes. It worked out. Thanks.

Now I am trying to upload a file to the sandbox. Any idea how to achieve this. I will post if I found one.

[shmoula]

Hi, I'm getting the same problem, where am I wrong?

wget –post-data=’{"name":"example","type":"file"}’ –header="Content-Type: text/plain" –http-user=admin –http-password=adminadmin http://172.31.149.197:8080/alfresco/service/api/wcm/webprojects/hjd/sandboxes/hjd--admin/assets/

or

curl -i -H "Content-Type: application-json" -X POST –user admin:vyzkumpivorum -d "{\"name\":\"example\",\"type\":\"file\"}" http://172.31.149.197:8080/alfresco/service/api/wcm/webprojects/hjd/sandboxes/hjd--admin/assets/

Is there any documentation for these webscripts, or do I need to do it as usualy - checkout sourcecode and look inside?

[shmoula]

Content-type: application/json helped a little, but I'm still stucked:
