UCenter注册流程拆解

调用注册方法

$uid = uc_user_register($_POST['username'], $_POST['password'], $_POST['email']);

uc_client/client.php

...
L:22
define('UC_API_FUNC', UC_CONNECT == 'mysql' ? 'uc_api_mysql' : 'uc_api_post');
...
L:300
function uc_user_register($username, $password, $email, $questionid = '', $answer = '', $regip = '') {
    return call_user_func(UC_API_FUNC, 'user', 'register', array('username'=>$username, 'password'=>$password, 'email'=>$email, 'questionid'=>$questionid, 'answer'=>$answer, 'regip' => $regip));
}

所以也就是调用了方法

uc_api_mysql('user', 'register', array(...))

找到对应方法

L:90
function uc_api_mysql($model, $action, $args=array()) {
    global $uc_controls;
    if(empty($uc_controls[$model])) {
        include_once UC_ROOT.'./lib/db.class.php';
        include_once UC_ROOT.'./model/base.php';
        include_once UC_ROOT."./control/$model.php";  //引入了./control/user.php
        eval("\$uc_controls['$model'] = new {$model}control();");
    }
    if($action{0} != '_') {
        $args = uc_addslashes($args, 1, TRUE);
        $action = 'on'.$action; //调用的方法动作为 onregister
        $uc_controls[$model]->input = $args;
        return $uc_controls[$model]->$action($args);
    } else {
        return '';
    }
}

        $uid = $_ENV['user']->add_user($username, $password, $email, 0, $questionid, $answer, $regip); //方法在uc_client/model/user.php:129
        return $uid;
    }
