关于thinkphp6:ThinkPHP6通过Ucenter实现注册登录

在和ucenter通信胜利后，实现注册登录就非常简单了。简要记录如下。

1 新建一个controller用来继承Ucenter\Controller\UcController,并新建构造方法，用来实例化UcController

<?php
declare (strict_types = 1);

namespace app\controller;

use Ucenter\Controller\UcController;
class uc extends UcController
{
    /**
     * 构造方法，用于实例化 UcController
     */
    public function __construct(){
        $this->init();
    }
}

2 index controller增加uc类变量。
private $uc;

3 index办法中实例化uc控制器，对UCenter接口的操作通过$this->uc来实现。
$this->uc = new uc();

以上两步实现后，就能够在代码适合的中央调用ucenter接口进行注册登录了。以下是我我的项目中的代码片段，仅供参考。

4 注册时验证用户名是否曾经存在以及是否非法

                $username = $data['Content'];
                $result = $this->uc->uc_check_name($username);
                switch ($result) {
                    case -1:
                        $reason = "用户名不非法";
                        break;
                    case -2:
                        $reason = "蕴含不容许注册的词语";
                        break;
                    case -3:
                        $reason = "用户名曾经存在";
                        break;
                }
                if ($result != 1) {
                    $this->_resetStep();
                    return array(join("\n", array_merge(array('【注册】注册失败', $reason), $this->_guestActions()
                    )),
                        'text');
                } else {
                    $this->_setStep(self::STEP_REGISTER_PASSWORD);
                    Session::set('username', $data['Content']);

                    return array('【注册】请输出明码', 'text');
                }
            }

5 输出明码后调用ucenter进行注册，因为ucenter注册时必带username，password，email，所以须要为用户生成默认的email

            //注册->输出明码
            if ($this->_currentStep() == self::STEP_REGISTER_PASSWORD) {
                $this->_resetStep();
                Session::set('password', $data['Content']);
                //call ucenter to register user
                $username_valid = $this->uc->uc_check_name(Session::get('username'));
                Log::write('$username_valid' . $username_valid, 'debug');
                if ($username_valid == 1) {
                    //register
                    Log::write('start register ' . Session::get('username'), 'debug');
                    $email = "reg_" . substr(Session::getId(), 0, 3) . time() . substr(Session::getId(), 7, 4) .
                        "@null.null";
                    //$email = Session::get('username').'@'.Session::get('username').'.com';
                    $register_result = $this->uc->uc_register(Session::get('username'), Session::get('password'),
                        $email);
                    Log::write('register result is ' . $register_result, 'debug');
                    switch ($register_result) {
                        case -1:
                            $reason = "用户名不非法";
                            break;
                        case -2:
                            $reason = "蕴含不容许注册的词语";
                            break;
                        case -3:
                            $reason = "用户名曾经存在";
                            break;
                        case -4:
                            $reason = "Email格局有误";
                            break;
                        case -5:
                            $reason = "Email不容许注册";
                            break;
                        case -6:
                            $reason = "该Email曾经被注册";
                            break;
                    }
                    if ($register_result > 0) {
                        Log::write('Ucenter register successful' . Session::get('username'), 'debug');
                        return array(join("\n", array_merge(array('【注册】注册胜利'), $this->_guestActions())), 'text');
                    } else {
                        Log::write('Ucenter register failed' . $reason, 'debug');
                        $this->_resetSession();
                        return array(join("\n", array_merge(array('【注册】注册失败', $reason), $this->_guestActions()
                        )),
                            'text');
                    }
                }

            }

6 登录时传入用户输出的用户名和明码即可。登陆胜利后将用户名和明码写入session文件。

$result = $this->uc->uc_login(Session::get('username'), $data['Content']);
