Hi,
\nIn one of my Grails project, i needed to have Share<\/strong> feature on the messages\/post published by our application on facebook wall.
\nIn Facebook, if the message\/text published is simple text, then Share<\/strong> link appears on it, but if it contains any link\/URL attached to it, then Facebook do not provides Share button on it.<\/p>\n

\r\n<\/pre>\n
To implement it, i created my own Share<\/strong> button and thought it worth sharing.<\/p>\n
\r\n<\/pre>\n
Publishing to facebook wall post requires facebook access_token and we have to do a post call to publish it on facebook wall.
\nI am assuming that you already have the access_token, if not you can find how to get access_token from here<\/a><\/p>\n
\r\n<\/pre>\n
Basic URL to share somthing on facebook wall is as below<\/p>\n
[java]<\/p>\n
    private static final String SHARE_BUTTON_BASIC_URL = &quot;http:\/\/www.facebook.com\/sharer.php?u=&quot;
\n    private static final String BUTTON_NAME = &quot;Share This&quot; \/\/ name to appear on the Share button<\/p>\n
[\/java]<\/p>\n
To create our own ‘Share’ button, we have to oass the custom button parameters in ‘actions’ attribute of the post call.<\/p>\n
Code to publish message\/post which contains any link attachment is as :-<\/p>\n
[java]
\n      String message=  \/\/Message to be published on facebook wall
\n      String access_token= \/\/ facebook access token
\n      String attachmentImageUrl= \/\/ Url of the image to be published in the wall post
\n      String attachmentLink= \/\/ Link attached with the message<\/p>\n
       StringBuilder sb = new StringBuilder(&quot;access_token=&quot;);
\n        sb.append(URLEncoder.encode(access_token, &quot;UTF-8&quot;));
\n        sb.append(&quot;&amp;message=&quot;);
\n        sb.append(URLEncoder.encode(message, &quot;UTF-8&quot;));
\n        sb.append(&quot;&amp;picture=&quot;);
\n        sb.append(URLEncoder.encode(attachmentImageUrl, &quot;UTF-8&quot;));
\n        sb.append(&quot;&amp;link=&quot;);
\n        sb.append(URLEncoder.encode(attachmentLink, &quot;UTF-8&quot;));
\n        sb.append(&quot;&amp;actions=&quot;)
\n        sb.append(URLEncoder.encode(&quot;[{name: ‘${BUTTON_NAME}’, link: ‘${SHARE_BUTTON_BASIC_URL}${attachmentLink}’ }]&quot;, &quot;UTF-8&quot;));<\/p>\n
            URL url = new URL(‘https:\/\/graph.facebook.com\/feed’);
\n            HttpURLConnection connection
\n            connection = (HttpURLConnection) url.openConnection();
\n            connection.setRequestMethod(&quot;POST&quot;);
\n            connection.setRequestProperty(&quot;Content-Type&quot;, &quot;application\/x-www-form-urlencoded&quot;);
\n            connection.setRequestProperty(&quot;Content-Length&quot;, &quot;&quot; + sb.toString().length());
\n            OutputStreamWriter outputStreamWriter = new OutputStreamWriter(connection.getOutputStream());
\n            outputStreamWriter.write(sb.toString());
\n            outputStreamWriter.flush();
\n            connection?.disconnect()<\/p>\n
[\/java]<\/p>\n
So, whatever we provide in the ‘actions’ property of post call, will appear in the wall post with the defined action. Here we are using it as link to Share a facebook wall post.<\/p>\n
\r\n<\/pre>\n
Sample post with custom ‘Share This’ link on facebook Wall<\/strong><\/p>\n
\n<\/div>\n
\r\n<\/pre>\n
\r\n<\/pre>\n
This worked in my case.
\nHope it helps.<\/p>\n
Cheers!!!<\/p>\n
