Hi,
\nIn one of my Grails project, i needed to ‘Like’ any Facebook wall post using facebook API. I searched about it and found a way to achieve this using Facebook Graph API<\/a> and thought it worth sharing.<\/p>\n

<\/pre>\n
To achieve it, we should have a valid facebook access_token, which can be obtained using steps described here<\/a>.<\/p>\n
<\/pre>\n
After obtaining a valid access_token, we can use graph API to like any Facebook Wall post.<\/p>\n
<\/pre>\n
We need to have the post_id<\/strong> of the facebook post, which we wants to ‘Like’.<\/p>\n
<\/pre>\n
Code to achieve this is as :-<\/p>\n
[java]
\nString access_token=ACCESS_TOKEN \/\/ access_token obtained from facebook.
\nString postId=POST_ID \/\/ id of the facebook wall post, which is to be ‘Liked’.<\/p>\n
 String feedUrl = "https:\/\/graph.facebook.com\/${postId}\/likes"
\n StringBuilder sb = new StringBuilder("access_token=");
\n sb.append(URLEncoder.encode(oAuthToken, "UTF-8"));
\n URL url = new URL(feedUrl);
\n HttpURLConnection connection
\n try {
\n connection = (HttpURLConnection) url.openConnection();
\n connection.setDoOutput(true);
\n connection.setRequestMethod("POST");
\n connection.setRequestProperty("Content-Type", "multipart\/form-data");
\n connection.setRequestProperty("Content-Length", "" + sb.toString().length());
\n OutputStreamWriter outputStreamWriter = new OutputStreamWriter(connection.getOutputStream());
\n outputStreamWriter.write(sb.toString());
\n outputStreamWriter.flush();
\n }
\n catch (Exception e) {
\n  e.printStackTrace()
\n }<\/p>\n
[\/java]<\/p>\n
<\/pre>\n
This issues a POST call for ‘Like’ that particular wall post on facebook.<\/p>\n
<\/pre>\n
This worked for me :).
\nHope it helps.<\/p>\n
<\/pre>\n
