此篇用來介紹Facebook API發文的三種方式，
分別是JavaScript SDK、PHP SDK以及Java SDK。
首先是JavaScript SDK，
下方程式碼使用FB.api來進行發文動作，
社團以及粉絲頁的動作幾乎一模一樣，
唯一的差別是粉絲頁需使用粉絲頁專用Token，
取得方式請看前一篇取得社團及粉絲頁資訊。

| /* 社團 */ | |
| FB.api( | |
| "/{page-id}/feed", | |
| "POST", | |
| { | |
| "message": "This is a test message", | |
| }, | |
| function (response) { | |
| if (response && !response.error) { | |
| /* handle the result */ | |
| } | |
| } | |
| ); | |
| /* 粉絲頁 */ | |
| FB.api( | |
| "/{page-id}/feed", | |
| "POST", | |
| { | |
| "message": "This is a test message", | |
| "access_token":accessTokenEpire | |
| /* accessTokenEpire是粉絲頁專用token */ | |
| }, | |
| function (response) { | |
| if (response && !response.error) { | |
| /* handle the result */ | |
| } | |
| } | |
| ); |
再來是PHP SDK，
PHP要先載入Facebook專用的SDK，
如需下載請參考第三篇淺談SDK種類及使用時機，
一樣要注意的是 access-token 有分一般級粉絲頁專用的token。

| /* PHP SDK v5.0.0 */ | |
| /* make the API call */ | |
| try { | |
| // Returns a `Facebook\FacebookResponse` object | |
| $response = $fb->post( | |
| '/{page-id}/feed', | |
| array ( | |
| 'message' => 'This is a test message', | |
| ), | |
| '{access-token}' | |
| ); | |
| } catch(Facebook\Exceptions\FacebookResponseException $e) { | |
| echo 'Graph returned an error: ' . $e->getMessage(); | |
| exit; | |
| } catch(Facebook\Exceptions\FacebookSDKException $e) { | |
| echo 'Facebook SDK returned an error: ' . $e->getMessage(); | |
| exit; | |
| } | |
| $graphNode = $response->getGraphNode(); | |
| /* handle the result */ |
最後是Java SDK，
跟PHP一樣要先載入專用的SDK，
我選的是 第三方SDK→Java→Mark Allen 開發的 RestFB。

| /* token 的使用需判斷是社團或粉絲頁*/ | |
| FacebookClient facebookClient = new DefaultFacebookClient(token,Version.LATEST); | |
| FacebookType publishMessageResponse = facebookClient.publish("/"+target_id+"/feed", FacebookType.class, Parameter.with("message", message)); | |
| /* target_id為社團或粉絲頁ID */ |
