一、新增數(shù)據(jù)庫字段

-- 添加用戶來源及第三方登錄字段
ALTER TABLE `wa_users`
ADD COLUMN `source` varchar(32) COLLATE utf8mb4_general_ci DEFAULT 'web' COMMENT '用戶來源(web/miniprogram/app)' AFTER `status`,
ADD COLUMN `openid` varchar(64) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '小程序openid' AFTER `source`,
ADD COLUMN `unionid` varchar(64) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '小程序unionid' AFTER `openid`,
ADD COLUMN `register_ip` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL COMMENT '注冊IP' AFTER `unionid`,
ADD COLUMN `register_time` datetime DEFAULT NULL COMMENT '注冊時間' AFTER `register_ip`;

-- 添加索引
ALTER TABLE `wa_users`
ADD INDEX `idx_source` (`source`),
ADD UNIQUE INDEX `idx_openid` (`openid`),
ADD INDEX `idx_register_time` (`register_time`);

二、后端實現(xiàn)（Webman Admin）

1. 控制器 app/admin/controller/Miniprogram.php
   因Webman Admin插件目錄app/admin不存在，所以在/www/wwwroot/webman/plugin/admin/app/controller新建了Miniprogram.php

   
   <?php
   namespace app\admin\controller;

use app\admin\model\WaUsers;
use support\Request;
use Respect\Validation\Validator as v;
use Webman\Redis;

class Miniprogram
{
/**

• 小程序用戶注冊
  */
  public function register(Request $request)
  {
  // 驗證請求數(shù)據(jù)
  $validator = v::key('username', v::stringType()->length(4, 20))
  ->key('password', v::stringType()->length(6, 32));

  try {
      $validator->assert($request->post());
  } catch (\Exception $e) {
      return json(['code' => 400, 'msg' => $e->getMessage()]);
  }
  
  $username = $request->post('username');
  $password = $request->post('password');
  $ip = $request->getRealIp();
  
  // 檢查用戶名是否已存在
  if (WaUsers::where('username', $username)->exists()) {
      return json(['code' => 400, 'msg' => '用戶名已存在']);
  }
  
  // 檢查IP注冊頻率（防批量注冊）
  $redisKey = "register:ip:{$ip}";
  $registerCount = Redis::get($redisKey) ?: 0;
  
  if ((int)$registerCount >= 5) {
      return json(['code' => 403, 'msg' => '注冊過于頻繁，請稍后再試']);
  }
  
  // 增加IP注冊計數(shù)（有效期1小時）
  Redis::incr($redisKey);
  Redis::expire($redisKey, 3600);
  
  try {
      // 創(chuàng)建用戶
      $user = WaUsers::create([
          'username' => $username,
          'password' => password_hash($password, PASSWORD_DEFAULT),
          'nickname' => $username,
          'source' => 'miniprogram',
          'register_ip' => $ip,
          'register_time' => date('Y-m-d H:i:s'),
          'join_time' => date('Y-m-d H:i:s'),
          'join_ip' => $ip,
          'status' => 1, // 啟用狀態(tài)
          'role' => 1,   // 普通用戶角色
          'created_at' => date('Y-m-d H:i:s'),
          'updated_at' => date('Y-m-d H:i:s')
      ]);
  
      return json([
          'code' => 200, 
          'msg' => '注冊成功',
          'data' => ['user_id' => $user->id]
      ]);
  } catch (\Exception $e) {
      return json(['code' => 500, 'msg' => '注冊失敗，請重試']);
  }

  }
  }

  
  2. 路由配置 app/admin/route/route.php
  因為app/admin下沒有route文件夾，route。php在/www/wwwroot/webman/plugin/admin/config目錄下，所以在/www/wwwroot/webman/plugin/admin/config/route.php添加了
  ```php
  use support\Route;

// 小程序接口
Route::group('/api/miniprogram', function () {
Route::post('/register', [\app\admin\controller\Miniprogram::class, 'register']);
});

### 完整內(nèi)容如下：
```php
<?php

use plugin\admin\app\controller\AccountController;
use plugin\admin\app\controller\DictController;
use Webman\Route;
use support\Request;
use support\Route;

// 小程序接口
Route::group('/api/miniprogram', function () {
    Route::post('/register', [\app\admin\controller\Miniprogram::class, 'register']);
});

Route::any('/app/admin/account/captcha/{type}', [AccountController::class, 'captcha']);

Route::any('/app/admin/dict/get/{name}', [DictController::class, 'get']);

Route::fallback(function (Request $request) {
    return response($request->uri() . ' not found' , 404);
}, 'admin');

到這一步，后臺就打不開了，給的步驟還沒執(zhí)行完
