Drupal 集成 Question2Answer(用户整合)

Drupal 有客 566浏览 0评论

Question2Answer是一个开源的在线问答系统,支持评论、投票、积分和排行榜等功能。虽然 Drupal 也有各种问答的解决方案。但对于数据量比较大的问答网站,Question2Answer应该是一个更好的选择。如果能够与 Drupal集成,利用Drupl的一些特性,似乎更好。下面我就来介绍一下集成的方法:

其实Question2Answer本身就提供了与外部系统集成的接口,我们只要进行少量的编码,修改这个接口文件就可以实现与Drupal的同步注册、登录和退出等功能。

  1. 先安装Drupal。
  2. 下载 Question2Answer 1.5.2,并解压到Drupal的安装目录下,并将文件夹question2answer重命名为 qa。
  3. 将 qa 目录下的 qa-external-example 重命名为 qa-external。
  4. 用你喜欢的编辑器打开qa-external目录下的 qa-external-users.php。
  5. 添加登录的链接。查找:function qa_get_login_links($relative_url_prefix, $redirect_back_to_url)在这个函数中添加如下代码:
    return array(
                'login' => $relative_url_prefix.'../user?destination=qa',
                'register' =>  $relative_url_prefix.'../user/register',
                'logout' =>  $relative_url_prefix.'../user/logout',
            );
  6. 获取登录用户。查找 function qa_get_logged_in_user()。 在这个函数中添加如何代码:
    if ($_COOKIE) {
                     
                   // $uid = $GLOBALS['user']->uid;
                    foreach ($_COOKIE as $key => $value) {
                        if(substr_compare($key, 'SESS', 0)>0){
                             
                            $qa_db_connection=qa_db_connection();           
                $result=mysql_fetch_assoc(
                    mysql_query(
                        "SELECT uid, name, mail FROM users WHERE uid=".     //, admin_flag
                        "(SELECT uid FROM sessions WHERE sid='".mysql_real_escape_string($_COOKIE[$key], $qa_db_connection)."')",
                        $qa_db_connection
                    )
                );
                 
                if (is_array($result))
                    return array(
                        'userid' => $result['uid'],
                        'publicusername' => $result['name'],
                        'email' => $result['mail'],
                        'level' => $result['uid']==1 ? QA_USER_LEVEL_ADMIN : QA_USER_LEVEL_BASIC
                    );
                        }
                    }
                 
            }
         
            return null;
  7. 获取用户的Email地址。查找 function qa_get_user_email($userid)。 在这个函数中添加如何代码:
    $qa_db_connection=qa_db_connection();
         
        $result=mysql_fetch_assoc(
            mysql_query(
                "SELECT mail FROM users WHERE uid='".mysql_real_escape_string($userid, $qa_db_connection)."'",
                $qa_db_connection
            )
        );
         
        if (is_array($result))
            return $result['mail'];
         
        return null;

…. 还有些就不细说了,下面是全部代码:

    function qa_get_login_links($relative_url_prefix, $redirect_back_to_url)

    ===========================================================================
 
    You should return an array containing URLs for the login, register and logout pages on
    your site. These URLs will be used as appropriate within the Q2A site.
     
    You may return absolute or relative URLs for each page. If you do not want one of the links
    to show, omit it from the array, or use null or an empty string.
     
    If you use absolute URLs, then return an array with the URLs in full (see example 1 below).
 
    If you use relative URLs, the URLs should start with $relative_url_prefix, followed by the
    relative path from the root of the Q2A site to your login page. Like in example 2 below, if
    the Q2A site is in a subdirectory, $relative_url_prefix.'../' refers to your site root.
     
    Now, about $redirect_back_to_url. Let's say a user is viewing a page on the Q2A site, and
    clicks a link to the login URL that you returned from this function. After they log in using
    the form on your main site, they want to automatically go back to the page on the Q2A site
    where they came from. This can be done with an HTTP redirect, but how does your login page
    know where to redirect the user to? The solution is $redirect_back_to_url, which is the URL
    of the page on the Q2A site where you should send the user once they've successfully logged
    in. To implement this, you can add $redirect_back_to_url as a parameter to the login URL
    that you return from this function. Your login page can then read it in from this parameter,
    and redirect the user back to the page after they've logged in. The same applies for your
    register and logout pages. Note that the URL you are given in $redirect_back_to_url is
    relative to the root of the Q2A site, so you may need to add something.
