Facebook應用程式開發-使用 PHP SDK

3.0之後的版本要把原有的權限判斷 "req_perms" 更改為 "scope"

Facebook api 權限控制

步驟一、下載PHP SDK

網址: https://github.com/facebook/php-sdk/
下載下來解壓縮後可以看到以下幾個資料夾，examples、src、tests

您可以直接修改範例裡頭的檔案，只要更改應用程式ID、API金匙
還有應用程式密匙，也就是上一篇建立完成後所產生的(不懂的話看上一篇)

在此不介紹範例的程式，筆者這裡有用過，一開始還正常，之後就發生了錯誤

 Uncaught OAuthException: Error validating access token. thrown

所以底下是我尋找各種方案後所找到比較可靠的範例。
出處(感謝各位作者):
http://thinkdiff.net/facebook/php-sdk-graph-api-base-facebook-connect-tutorial/
這位作者寫的很好~假如看不懂英文，底下是我中文說明，以及修改的程式

 步驟二、建立連線
程式碼如下，都有打上註解(複製貼上吧)

<?php

$fbconfig['appid'] = "";
$fbconfig['secret'] = "";
try {
    include_once "src/facebook.php";
} catch (Exception $o) {
    echo '<pre>';
    print_r($o);
    echo '</pre>';
}

function p($d) {
    echo '<pre>';
    print_r($d);
    echo '</pre>';
}

$facebook = new Facebook(array(
            'appId' => $fbconfig['appid'],
            'secret' => $fbconfig['secret']
        ));
$uid = $facebook->getUser();
$login_url = $facebook->getLoginUrl//登入連結以及要取得使用者哪些資訊
        (
        array
            (
            "scope" => "id,link,username,birthday,email,user_photos", //要取得的使用者資訊
            'next' => 'http://apps.facebook.com/wingnetgraphapi/', //按下完成後轉向網址
            'redirect_uri' => 'http://apps.facebook.com/wingnetgraphapi/', //下一頁轉向網址
            'fbconnect' => 1,
            'canvas' => 1, //Facebook內的畫布，沒有用到，為0
        )
);
if (!$uid) {
    echo "<script type='text/javascript'>top.location.href = '" . $login_url . "';</script>";
    exit;
}
?> 

步驟三、取得使用者資訊
增加FQL，取得使用者所加入的粉絲資訊、取得使用者所加入的粉絲資訊、應用程式留言的資訊
如下程式碼

<?php
include_once "fbinclude.php";
if ($uid) {
    $fbme = $facebook->api('/me');
    //使用SDK函式提供的方法(users.getinfo)取得使用者資訊
    try {
        $param = array(
            'method' => 'users.getinfo',
            'uids' => $uid,
            'fields' => 'name,current_location,profile_url',
            'callback' => ''
        );
        $userInfo = $facebook->api($param);
    } catch (Exception $o) {
        p($o);
    }
    //使用FQL取得使用者資訊
    try {
        //get user id
        $uid = $facebook->getUser();
        //or you can use $uid = $fbme['id'];

        $fql = "select uid,name,profile_url, hometown_location, sex, pic_square from user where uid=" . $uid;
        $param = array(
            'method' => 'fql.query',
            'query' => $fql,
            'callback' => ''
        );
        $fqlResult = $facebook->api($param);
    } catch (Exception $o) {
        p($o);
    }

    try {
        //get user id
        $uid = $facebook->getUser();
        //or you can use $uid = $fbme['id'];
        $fqlfans = "SELECT page_id, name, type,pic FROM page WHERE page_id IN (SELECT page_id FROM page_fan WHERE uid=" . $uid . ")";
        $fans = array(
            'method' => 'fql.query',
            'query' => $fqlfans,
            'callback' => ''
        );
        $fansResult = $facebook->api($fans);
    } catch (Exception $o) {
        p($o);
    }
    //判斷使用者是否有加入粉絲專頁
    try {
        //get user id
        $uid = $facebook->getUser();
        $pageID = '261910770463';
        //or you can use $uid = $fbme['id'];
        $fans = "SELECT target_id,target_type,source_id,is_following,updated_time,is_deleted FROM connection WHERE source_id = $uid AND target_id = $pageID";
        $fansteam = array(
            'method' => 'fql.query',
            'query' => $fans,
            'callback' => ''
        );
        $fansteamResult = $facebook->api($fansteam);
    } catch (Exception $o) {
        p($o);
    }
    //END 判斷使用者是否有加入粉絲專頁
    //取得在此應用程式留言的使用者(以官方的文件為例)
    try {
        $comment = "select fromid, object_id, text, time from comment where object_id in (select post_fbid from comment where object_id in (select comments_fbid from link_stat where url ='http://developers.facebook.com/docs/reference/fql/comment/'))";
        $comments = array(
            'method' => 'fql.query',
            'query' => $comment,
            'callback' => ''
        );
        $commentResult = $facebook->api($comments);
    } catch (Exception $o) {
        p($o);
    }
    //END 取得在此應用程式留言的使用者 

    /* try {
      //get user id
      $uid = $facebook->getUser();
      //or you can use $uid = $fbme['id'];
      //        $fqlphotos="SELECT pid,src_big,link FROM photo WHERE aid IN ( SELECT aid FROM album WHERE owner='20531316728' ) ORDER BY created DESC LIMIT 1,42";
      $fqlphotos = "SELECT aid, owner, name, object_id,link FROM album WHERE aid='100002637024906_12582'";//取得相簿 owner
      $photos = array(
      'method' => 'fql.query',
      'query' => $fqlphotos,
      'callback' => ''
      );
      $photosResult = $facebook->api($photos);
      } catch (Exception $o) {
      p($o);
      } */

 ※ 請到官方網站 重新下載新的 Facebook PHP SDK ※

還是看不懂嗎…….

懶人包直接 下載 ，改一下應用程式ID、金匙、應用程式密匙
