开发环境配置与项目初始化

1. 使用Composer创建项目

# 创建ThinkPHP 6.x项目
composer create-project topthink/think cms-system

# 进入项目目录
cd cms-system

# 安装常用扩展
composer require topthink/think-multi-app
composer require topthink/think-migration

2. 多应用配置

// config/app.php
return [
    // 开启多应用
    'auto_multi_app'   => true,
    'app_express'      => true,
    
    // 默认应用
    'default_app'      => 'index',
    // 默认时区
    'default_timezone' => 'Asia/Shanghai',
];

3. 数据库配置

// config/database.php
return [
    // 默认数据连接标识
    'default' => 'mysql',
    
    // 数据库连接信息
    'connections' => [
        'mysql' => [
            'type' => 'mysql',
            'hostname' => '127.0.0.1',
            'database' => 'cms_system',
            'username' => 'root',
            'password' => '',
            'hostport' => '3306',
            'charset' => 'utf8mb4',
            'prefix' => 'cms_',
            'debug' => true,
        ],
    ],
];

数据库设计与模型构建

1. 数据表结构设计

// database/migrations/20231215001_create_cms_tables.php
<?php
use thinkmigrationMigrator;

class CreateCmsTables extends Migrator
{
    public function change()
    {
        // 用户表
        $table = $this->table('users', ['comment' => '用户表']);
        $table->addColumn('username', 'string', ['limit' => 50, 'comment' => '用户名'])
              ->addColumn('email', 'string', ['limit' => 100, 'comment' => '邮箱'])
              ->addColumn('password', 'string', ['limit' => 255, 'comment' => '密码'])
              ->addColumn('status', 'integer', ['default' => 1, 'comment' => '状态'])
              ->addTimestamps()
              ->addIndex(['username'], ['unique' => true])
              ->addIndex(['email'], ['unique' => true])
              ->create();
        
        // 文章表
        $table = $this->table('articles', ['comment' => '文章表']);
        $table->addColumn('title', 'string', ['limit' => 200, 'comment' => '标题'])
              ->addColumn('content', 'text', ['comment' => '内容'])
              ->addColumn('excerpt', 'string', ['limit' => 500, 'comment' => '摘要'])
              ->addColumn('user_id', 'integer', ['comment' => '作者ID'])
              ->addColumn('category_id', 'integer', ['comment' => '分类ID'])
              ->addColumn('status', 'integer', ['default' => 0, 'comment' => '状态'])
              ->addColumn('views', 'integer', ['default' => 0, 'comment' => '浏览量'])
              ->addTimestamps()
              ->addIndex(['user_id'])
              ->addIndex(['category_id'])
              ->addIndex(['status'])
              ->create();
        
        // 分类表
        $table = $this->table('categories', ['comment' => '分类表']);
        $table->addColumn('name', 'string', ['limit' => 50, 'comment' => '分类名称'])
              ->addColumn('parent_id', 'integer', ['default' => 0, 'comment' => '父级ID'])
              ->addColumn('sort', 'integer', ['default' => 0, 'comment' => '排序'])
              ->addTimestamps()
              ->create();
    }
}
?>

2. 模型定义与关联

// app/model/User.php
<?php
namespace appmodel;

use thinkModel;
use thinkmodelconcernSoftDelete;

class User extends Model
{
    use SoftDelete;
    
    protected $name = 'users';
    protected $pk = 'id';
    
    // 自动时间戳
    protected $autoWriteTimestamp = true;
    
    // 字段类型转换
    protected $type = [
        'status' => 'integer',
    ];
    
    // 密码自动加密
    public function setPasswordAttr($value)
    {
        return password_hash($value, PASSWORD_DEFAULT);
    }
    
    // 定义文章关联
    public function articles()
    {
        return $this->hasMany(Article::class, 'user_id');
    }
}
?>
// app/model/Article.php
<?php
namespace appmodel;

use thinkModel;

class Article extends Model
{
    protected $name = 'articles';
    protected $pk = 'id';
    
    protected $autoWriteTimestamp = true;
    
    protected $type = [
        'status' => 'integer',
        'views' => 'integer',
    ];
    
    // 自动写入摘要
    public function setExcerptAttr($value, $data)
    {
        if (empty($value) && isset($data['content'])) {
            return mb_substr(strip_tags($data['content']), 0, 200);
        }
        return $value;
    }
    
    // 定义作者关联
    public function author()
    {
        return $this->belongsTo(User::class, 'user_id');
    }
    
    // 定义分类关联
    public function category()
    {
        return $this->belongsTo(Category::class, 'category_id');
    }
    
    // 状态获取器
    public function getStatusTextAttr($value, $data)
    {
        $status = $data['status'] ?? 0;
        $statusMap = [0 => '草稿', 1 => '已发布', 2 => '已下线'];
        return $statusMap[$status] ?? '未知';
    }
}
?>

核心模块开发实战

1. 后台文章管理控制器

// app/admin/controller/Article.php
<?php
namespace appadmincontroller;

use appBaseController;
use appmodelArticle as ArticleModel;
use appmodelCategory;
use thinkfacadeView;
use thinkfacadeRequest;

class Article extends BaseController
{
    protected $middleware = [
        'auth' => ['except' => []]
    ];
    
    public function index()
    {
        $page = Request::param('page', 1);
        $limit = Request::param('limit', 15);
        $keyword = Request::param('keyword', '');
        
        $query = ArticleModel::with(['author', 'category'])
                           ->order('id', 'desc');
        
        if (!empty($keyword)) {
            $query->whereLike('title', "%{$keyword}%");
        }
        
        $list = $query->paginate([
            'list_rows' => $limit,
            'page' => $page
        ]);
        
        return View::fetch('index', [
            'list' => $list,
            'keyword' => $keyword
        ]);
    }
    
    public function create()
    {
        if (Request::isPost()) {
            $data = Request::post();
            
            try {
                $article = ArticleModel::create($data);
                return json(['code' => 1, 'msg' => '创建成功', 'data' => $article]);
            } catch (Exception $e) {
                return json(['code' => 0, 'msg' => '创建失败: ' . $e->getMessage()]);
            }
        }
        
        $categories = Category::select();
        return View::fetch('create', ['categories' => $categories]);
    }
    
    public function edit($id)
    {
        $article = ArticleModel::find($id);
        if (!$article) {
            $this->error('文章不存在');
        }
        
        if (Request::isPost()) {
            $data = Request::post();
            
            try {
                $article->save($data);
                return json(['code' => 1, 'msg' => '更新成功']);
            } catch (Exception $e) {
                return json(['code' => 0, 'msg' => '更新失败: ' . $e->getMessage()]);
            }
        }
        
        $categories = Category::select();
        return View::fetch('edit', [
            'article' => $article,
            'categories' => $categories
        ]);
    }
    
    public function delete($id)
    {
        $article = ArticleModel::find($id);
        if (!$article) {
            return json(['code' => 0, 'msg' => '文章不存在']);
        }
        
        try {
            $article->delete();
            return json(['code' => 1, 'msg' => '删除成功']);
        } catch (Exception $e) {
            return json(['code' => 0, 'msg' => '删除失败: ' . $e->getMessage()]);
        }
    }
}
?>

2. API接口控制器

// app/api/controller/Article.php
<?php
namespace appapicontroller;

use appBaseController;
use appmodelArticle as ArticleModel;
use appmodelCategory;
use thinkfacadeRequest;

class Article extends BaseController
{
    public function index()
    {
        $page = Request::param('page', 1);
        $limit = Request::param('limit', 10);
        $categoryId = Request::param('category_id', 0);
        
        $query = ArticleModel::with(['author', 'category'])
                           ->where('status', 1)
                           ->order('id', 'desc');
        
        if ($categoryId > 0) {
            $query->where('category_id', $categoryId);
        }
        
        $list = $query->paginate([
            'list_rows' => $limit,
            'page' => $page
        ]);
        
        return json([
            'code' => 1,
            'data' => $list->items(),
            'total' => $list->total(),
            'page' => $list->currentPage()
        ]);
    }
    
    public function read($id)
    {
        $article = ArticleModel::with(['author', 'category'])
                             ->where('status', 1)
                             ->find($id);
        
        if (!$article) {
            return json(['code' => 0, 'msg' => '文章不存在']);
        }
        
        // 增加浏览量
        $article->setInc('views');
        
        return json(['code' => 1, 'data' => $article]);
    }
}
?>

3. 自定义中间件:权限验证

// app/middleware/Auth.php
<?php
namespace appmiddleware;

use thinkfacadeRequest;
use thinkfacadeSession;

class Auth
{
    public function handle($request, Closure $next)
    {
        // 检查用户是否登录
        if (!Session::has('admin_user')) {
            if ($request->isAjax()) {
                return json(['code' => 401, 'msg' => '请先登录']);
            } else {
                return redirect('/admin/login');
            }
        }
        
        // 权限验证逻辑
        $user = Session::get('admin_user');
        $currentController = $request->controller();
        $currentAction = $request->action();
        
        // 这里可以添加更复杂的权限验证逻辑
        if (!$this->checkPermission($user, $currentController, $currentAction)) {
            if ($request->isAjax()) {
                return json(['code' => 403, 'msg' => '权限不足']);
            } else {
                return redirect('/admin/error/403');
            }
        }
        
        return $next($request);
    }
    
    private function checkPermission($user, $controller, $action)
    {
        // 简化版权限验证,实际项目中应该更复杂
        $superAdmin = [1]; // 超级管理员ID
        if (in_array($user['id'], $superAdmin)) {
            return true;
        }
        
        // 普通用户权限验证逻辑
        $allowedActions = [
            'Article' => ['index', 'create', 'edit'],
            // 更多控制器和动作的权限配置
        ];
        
        return isset($allowedActions[$controller]) && 
               in_array($action, $allowedActions[$controller]);
    }
}
?>

ThinkPHP高级特性应用

1. 服务层与依赖注入

// app/service/ArticleService.php
<?php
namespace appservice;

use appmodelArticle;
use thinkfacadeCache;

class ArticleService
{
    protected $articleModel;
    
    public function __construct(Article $article)
    {
        $this->articleModel = $article;
    }
    
    public function getHotArticles($limit = 10)
    {
        $cacheKey = 'hot_articles_' . $limit;
        
        return Cache::remember($cacheKey, function() use ($limit) {
            return $this->articleModel
                       ->where('status', 1)
                       ->order('views', 'desc')
                       ->limit($limit)
                       ->select();
        }, 3600); // 缓存1小时
    }
    
    public function createArticle($data)
    {
        // 数据验证
        $validate = new appvalidateArticle();
        if (!$validate->check($data)) {
            throw new Exception($validate->getError());
        }
        
        // 创建文章
        $article = $this->articleModel->create($data);
        
        // 清除相关缓存
        Cache::delete('hot_articles_10');
        Cache::delete('recent_articles_10');
        
        return $article;
    }
}
?>

2. 事件系统应用

// app/event/ArticleEvent.php
<?php
namespace appevent;

class ArticleEvent
{
    public function onCreated($article)
    {
        // 文章创建后的处理
        thinkfacadeLog::info('文章创建: ' . $article->title);
        
        // 发送通知等
        // $this->sendNotification($article);
    }
    
    public function onUpdated($article)
    {
        // 文章更新后的处理
        thinkfacadeLog::info('文章更新: ' . $article->title);
        
        // 清除缓存
        thinkfacadeCache::tag('article')->clear();
    }
}

// 在模型中使用事件
class Article extends Model
{
    protected static function init()
    {
        // 注册模型事件
        self::event('after_insert', function ($article) {
            event('ArticleCreated', $article);
        });
        
        self::event('after_update', function ($article) {
            event('ArticleUpdated', $article);
        });
    }
}
?>

3. 自定义验证器

// app/validate/Article.php
<?php
namespace appvalidate;

use thinkValidate;

class Article extends Validate
{
    protected $rule = [
        'title|标题' => 'require|max:200',
        'content|内容' => 'require|min:10',
        'category_id|分类' => 'require|number',
        'status|状态' => 'require|in:0,1,2',
    ];
    
    protected $message = [
        'title.require' => '标题不能为空',
        'title.max' => '标题长度不能超过200个字符',
        'content.require' => '内容不能为空',
        'content.min' => '内容长度不能少于10个字符',
        'category_id.require' => '请选择分类',
        'status.in' => '状态值不合法',
    ];
    
    protected $scene = [
        'create' => ['title', 'content', 'category_id', 'status'],
        'update' => ['title', 'content', 'category_id', 'status'],
    ];
}
?>

性能优化与生产部署

1. 路由优化配置

// route/app.php
<?php
use thinkfacadeRoute;

// 后台路由组
Route::group('admin', function () {
    Route::get('login', 'admin/Login/index');
    Route::post('login', 'admin/Login/doLogin');
    
    Route::group('', function () {
        Route::get('', 'admin/Index/index');
        Route::get('index', 'admin/Index/index');
        
        // 文章管理
        Route::get('articles', 'admin/Article/index');
        Route::get('articles/create', 'admin/Article/create');
        Route::post('articles/create', 'admin/Article/create');
        Route::get('articles/edit/:id', 'admin/Article/edit');
        Route::post('articles/edit/:id', 'admin/Article/edit');
        Route::post('articles/delete/:id', 'admin/Article/delete');
    })->middleware(appmiddlewareAuth::class);
});

// API路由组
Route::group('api', function () {
    Route::get('articles', 'api/Article/index');
    Route::get('articles/:id', 'api/Article/read');
})->allowCrossDomain();

2. 缓存配置优化

// config/cache.php
return [
    // 默认缓存驱动
    'default' => env('CACHE_DRIVER', 'redis'),
    
    // 缓存连接配置
    'stores' => [
        'file' => [
            'type' => 'File',
            'path' => '../runtime/cache/',
        ],
        'redis' => [
            'type' => 'redis',
            'host' => '127.0.0.1',
            'port' => 6379,
            'password' => '',
            'select' => 0,
            'timeout' => 0,
            'persistent' => false,
            'prefix' => 'cms:',
        ],
    ],
];

3. 生产环境配置

// .env.production
APP_DEBUG = false
APP_TRACE = false

# 数据库配置
DATABASE_HOSTNAME = 127.0.0.1
DATABASE_DATABASE = cms_production
DATABASE_USERNAME = production_user
DATABASE_PASSWORD = secure_password

# 缓存配置
CACHE_DRIVER = redis

# Session配置
SESSION_TYPE = redis

4. 部署脚本示例

#!/bin/bash
# deploy.sh

echo "开始部署CMS系统..."

# 拉取最新代码
git pull origin main

# 安装依赖
composer install --no-dev --optimize-autoloader

# 生成优化文件
php think optimize:route
php think optimize:schema

# 设置权限
chmod -R 755 runtime
chmod -R 755 public/uploads

# 重启服务
systemctl reload php-fpm

echo "部署完成!"
