ThinkPHP项目开发｜PHP网站开发全流程实战指南

// 控制器：app/controller/User.php
namespace appcontroller;
use thinkfacadeRequest;
class User {
    public function login() {
        $request = Request::param();
        // 表单验证
        $validate = new appvalidateUser();
        if (!$validate->scene('login')->check($request)) {
            return json(['code' => 400, 'msg' => $validate->getError()]);
        }
        // 调用模型处理登录
        $userModel = new appmodelUser();
        $result = $userModel->handleLogin($request['username'], $request['password']);
        return json($result);
    }
}

// 模型：app/model/Goods.php
namespace appmodel;
use thinkModel;
class Goods extends Model {
    // 自动时间戳
    protected $autoWriteTimestamp = true;
    // 关联查询：获取商品分类
    public function category() {
        return $this->belongsTo(Category::class, 'category_id');
    }
    // 业务方法：批量更新库存
    public function decreaseStock($ids, $amount) {
        return $this->where('id', 'in', $ids)
                   ->setDec('stock', $amount);
    }
}

{extend name="layout/base" /}
{block name="content"}
  

    
用户登录
    

      
      
      登录
    
  
{/block}

// 中间件：app/middleware/HandleException.php
namespace appmiddleware;
class HandleException {
    public function handle($request, Closure $next) {
        try {
            return $next($request);
        } catch (Exception $e) {
            // 记录详细日志
            thinkfacadeLog::error($e->getMessage(), [
                'file' => $e->getFile(),
                'line' => $e->getLine(),
                'trace' => $e->getTraceAsString()
            ]);
            // 返回统一格式
            return json([
                'code' => $e->getCode() ?: 500,
                'msg' => env('APP_DEBUG') ? $e->getMessage() : '系统异常，请稍后重试',
                'data' => []
            ]);
        }
    }
}

// ❌ 危险：直接拼接SQL
Db::query("SELECT  FROM users WHERE name = '".$_GET['name']."'");
// ✅ 安全：ThinkPHP自动参数化
Db::name('users')->where('name', input('get.name'))->find();

// 视图中生成令牌

// 控制器中验证（自动）
// 开启后所有POST请求需携带__token__参数，否则返回403

// 上传验证规则
$validate = new thinkvalidate([
  'file' => 'require|file|fileExt:jpg,png,gif|fileSize:2097152|fileMime:image/jpeg,image/png,image/gif'
]);
if (!$validate->check($request->file('file'))) {
    return json(['code' => 400, 'msg' => $validate->getError()]);
}

// 路由分组
Route::group('api/v1', function () {
    Route::post('login', 'api/v1/User/login');
    Route::get('products', 'api/v1/Product/index');
})->middleware(['auth', 'rateLimit']);
