UCenter应用程序开发简单实例(双向同步).doc

测试环境：IIS5.1 + PHP5.2.12 + MySQL5.0.88本程序使用的是PDO，所以php.ini中的extension=php_pdo.dll和extension=php_pdo_mysql.dll必须打开。首先安装UCenter1.5，路径：http:/localhost/ucenter然后进入后台添加一个新的应用，安装方式选择“自定义安装”；应用名称：我的应用1；应用URL：http:/localhost/myapp1；应用IP：；通信密钥先不用管；应用类型：其他；同步登录：是；接收通知：是。添加成功之后返回应用列表，可以看到“我的应用1”通信失败，暂时不用管。在http:/localhost所在的目录下新建一个文件夹，命名为myapp1，拷贝一份UCenter的客户端(uc_client)到myapp1目录下。在http:/localhost/myapp1所在的目录下新建一个文件夹，命名为api，拷贝一份UCenter的api(uc.php)到api目录下，官方Example中10KB的那个文件(但还是有点问题)。在http:/localhost/myapp1所在的目录下新建一个文件夹，命名为include，拷贝一份Discuz的db_mysql.class.php和db_mysql_error.inc.php到include目录下。在http:/localhost/myapp1所在的目录下新建一个config.inc.php文件，这是本应用的配置文件。在数据库里建立本应用的数据表，一般都需要有自己的数据表。准备工作完成了，下面详细介绍各个模块的代码。本应用程序的配置文件：config.inc.phpquery(set names gbk);/*define(UC_CONNECT, mysql);define(UC_DBHOST, localhost);define(UC_DBUSER, yutiedun);define(UC_DBPW, 11111111);define(UC_DBNAME, discuz);define(UC_DBCHARSET, gbk);define(UC_DBTABLEPRE, discuz.uc_);define(UC_DBCONNECT, 0);define(UC_KEY, 4961DYjLak6oE0cJq9jNDbxNUzSalwMXq6qp1X0);define(UC_API, http:/localhost/ucenter);define(UC_CHARSET, gbk);define(UC_IP, );define(UC_APPID, 5); /根据具体情况设置define(UC_PPP, 20);/*?UCenter接口文件：uc.php 3600) exit(Authracation has expiried);if(empty($get) exit(Invalid Request);$action = $getaction;require_once DISCUZ_ROOT./uc_client/lib/xml.class.php;$post = xml_unserialize(file_get_contents(php:/input);if(in_array($getaction, array(test, deleteuser, renameuser, gettag, synlogin, synlogout, updatepw, updatebadwords, updatehosts, updateapps, updateclient, updatecredit, getcreditsettings, updatecreditsettings) require_once DISCUZ_ROOT./include/db_mysql.class.php;$GLOBALSdb = new dbstuff;$GLOBALSdb-connect($dbhost, $dbuser, $dbpw, $dbname, $pconnect, true, $dbcharset);$GLOBALStablepre = $tablepre;unset($dbhost, $dbuser, $dbpw, $dbname, $pconnect);$uc_note = new uc_note();exit($uc_note-$getaction($get, $post); else exit(API_RETURN_FAILED);/note include 通知方式 else require_once DISCUZ_ROOT./config.inc.php;require_once DISCUZ_ROOT./include/db_mysql.class.php;$GLOBALSdb = new dbstuff;$GLOBALSdb-connect($dbhost, $dbuser, $dbpw, $dbname, $pconnect, true, $dbcharset);$GLOBALStablepre = $tablepre;unset($dbhost, $dbuser, $dbpw, $dbname, $pconnect);class uc_note var $dbconfig = ;var $db = ;var $tablepre = ;var $appdir = ;function _serialize($arr, $htmlon = 0) if(!function_exists(xml_serialize) include_once DISCUZ_ROOT./uc_client/lib/xml.class.php;return xml_serialize($arr, $htmlon);function uc_note() $this-appdir = substr(dirname(_FILE_), 0, -3);$this-dbconfig = $this-appdir./config.inc.php;$this-db = $GLOBALSdb;$this-tablepre = $GLOBALStablepre;function test($get, $post) return API_RETURN_SUCCEED;function deleteuser($get, $post) $uids = $getids;!API_DELETEUSER & exit(API_RETURN_FORBIDDEN);return API_RETURN_SUCCEED;function renameuser($get, $post) $uid = $getuid;$usernameold = $getoldusername;$usernamenew = $getnewusername;if(!API_RENAMEUSER) return API_RETURN_FORBIDDEN;return API_RETURN_SUCCEED;function gettag($get, $post) $name = $getid;if(!API_GETTAG) return API_RETURN_FORBIDDEN;$return = array();return $this-_serialize($return, 1);function synlogin($get, $post) $uid = $getuid;$username = $getusername;if(!API_SYNLOGIN) return API_RETURN_FORBIDDEN;/note 同步登入 API 接口header(P3P: CP=CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR);_setcookie(loginstat, _authcode($uid.t.$username, ENCODE);function synlogout($get, $post) if(!API_SYNLOGOUT) return API_RETURN_FORBIDDEN;/note 同步登出 API 接口header(P3P: CP=CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR);_setcookie(loginstat, , -86400 * 365);function updatepw($get, $post) if(!API_UPDATEPW) return API_RETURN_FORBIDDEN;$username = $getusername;$password = $getpassword;return API_RETURN_SUCCEED;function updatebadwords($get, $post) if(!API_UPDATEBADWORDS) return API_RETURN_FORBIDDEN;$cachefile = $this-appdir./uc_client/data/cache/badwords.php;$fp = fopen($cachefile, w);$data = array();if(is_array($post) foreach($post as $k = $v) $datafindpattern$k = $vfindpattern;$datareplace$k = $vreplacement;$s = appdir./uc_client/data/cache/hosts.php;$fp = fopen($cachefile, w);$s = appdir./uc_client/data/cache/apps.php;$fp = fopen($cachefile, w);$s = appdir./config.inc.php) $configfile = trim(file_get_contents($this-appdir./config.inc.php);$configfile = substr($configfile, -2) = ?
