我想实现一个用户跟踪系统，经过搜索我意识到我必须在中间件中做到这一点。我遇到的问题是我只能将值添加到中间件中答案中的响应标头。保存它们的信息后，在中间件响应中删除它们。请指导我如何将自定义数据添加到中间件响应中，谢谢
为此，我找到了 2 个在 json 模式下工作的示例，但如果我想将用户转移到路由，我必须使用标头。
json 响应示例代码：
return $response->json([
'status' => $status,
'code' => $code,
'errors' => [$errors],
], $status);
我在我的项目中做了完全相同的系统，但没有使用标头，请参阅下面的示例
例如： 我们计划为每个用户在软件中的表现创建一个跟踪系统，以便将其报告存储在系统中。
迁移：
Schema::create('user_trackings', function (Blueprint $table) {
$table->id();
$table->boolean('transaction')->default(1);
$table->string('event');
$table->string('class');
$table->longText('request_params')->nullable();
$table->string('request_method');
$table->string('request_ip');
$table->string('request_userAgent');
$table->longText('params')->nullable();
$table->foreignId('user_id')->constrained()->onUpdate('cascade')->onDelete('cascade');
$table->timestamps();
$table->softDeletes();
});
角色控制器：
use App\Traits\Response;
class RoleController extends Controller
{
use Response;
public function store(Request $request)
{
$Validator = Validator::make($request->all(), [
'display_name' => ['required', 'unique:roles,display_name', 'max:255'],
'name' => ['required', 'unique:roles,name', 'persian_not_accept', 'max:255'],
'permissions' => ['nullable', "array","min:1"],
'permissions.*' => ['nullable', 'exists:permissions,name'],
'parent' => [new ParentRule('roles,name')]
]);
if ($Validator->fails()) {
$this->Validation($Validator);
return back();
}
DB::beginTransaction();
try {
$Role = Role::create([
'name' => $request->name,
'display_name' => $request->display_name
]);
$Role->syncPermissions($request->permissions);
if($request->parent != 'no-parent'){
$RoleParent = Role::findByName($request->parent);
$Role->parent()->associate($RoleParent);
$Role->save();
}
DB::commit();
} catch (\Exception $e) {
DB::rollback();
$this->Error([
'Permission' => $Role,
'Exception' => $e->getMessage()
]);
}
return $this->Success([
'Permission' => $Role
], 'role.index');
}
}
响应特征：
trait Response {
use SweetAlert;
public function Success($Params = [], $Route = null , $RouteParams = [], $title = null, $message = null){
$title = is_null($title) ? __('message.response.title.Success') : $title;
$message = is_null($message) ? __('message.response.message.Success') : $message;
if($Route){
return (new RedirectResponse(route($Route, $RouteParams)))->bag(true, $Params);
}
return (new HttpResponse)->json(['status' => true, 'message' => $message])->bag(true, $Params);
}
public function Error($Params = [], $Route = null , $RouteParams = [], $title = null, $message = null){
$title = is_null($title) ? __('message.response.title.Error') : $title;
$message = is_null($message) ? __('message.response.message.Error') : $message;
if($Route){
$this->AlertError( $title , $message );
return (new RedirectResponse(route($Route, $RouteParams)))->bag(false, $Params);
}
return (new HttpResponse)->json(['status' => false, 'message' => $message])->bag(false, $Params);
}
}
提示： 在中间件响应中，您将收到 2 种类型的响应，它们由 2 个类组成（Illuminate\Http\Response、Illuminate\Http\RedirectResponse），因此我们必须为此创建 2 个自定义类并扩展这 2 个类。
创建自定义响应：
1- 第一级：
namespace App\Library\Response;
use Illuminate\Http\RedirectResponse as BaseRedirectResponse;
class RedirectResponse extends BaseRedirectResponse {
public $bag;
public function bag($Status = null, $Data = null){
$this->bag = (object) [
'Status' => $Status,
'Data' => $Data
];
return $this;
}
}
2- 第二类：
namespace App\Library\Response;
use Illuminate\Http\Response;
class HttpResponse extends Response {
public $bag;
public function bag($Status = null, $Data = null){
$this->bag = (object) [
'Status' => $Status,
'Data' => $Data
];
return $this;
}
}
我们创建用户跟踪存储特征
namespace App\Traits;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Log;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Route;
use App\Models\UserTracking as ModelUserTracking;
trait UserTracking{
public function Track($Transaction = true, $Params = []){
DB::beginTransaction();
try {
$UserTracking = new ModelUserTracking;
$UserTracking->transaction = $Transaction;
$UserTracking->event = Route::currentRouteName();
$UserTracking->class = Route::currentRouteAction();
$UserTracking->request_params = json_encode(request()->all());
$UserTracking->request_method = Route::current()->methods()[0];
$UserTracking->request_ip = request()->ip();
$UserTracking->request_userAgent = request()->userAgent();
if(!empty($Params)): $UserTracking->params = json_encode($Params); endif;
$UserTracking->User()->associate(Auth::user());
$UserTracking->save();
DB::commit();
} catch (\Exception $e) {
DB::rollback();
Log::error("Insert User Tracking Data Error", [
'UserTracking' => $UserTracking,
'Exception' => $e->getMessage()
]);
}
}
}
现在我们开始构建自定义中间件
自定义中间件：
namespace App\Http\Middleware;
use Closure;
use App\Traits\UserTracking as TraitUserTracking;
use Illuminate\Http\Request;
class UserTracking
{
use TraitUserTracking;
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure(\Illuminate\Http\Request): (\App\Library\Response\HttpResponse|\App\Library\Response\RedirectResponse) $next
* @return \App\Library\Response\HttpResponse|\App\Library\Response\RedirectResponse
*/
public function handle(Request $request, Closure $next)
{
$response = $next($request);
if(property_exists($response, 'bag'))
$this->Track($response->bag->Status, $response->bag->Data);
return $response;
}
}
本指南的要点是，您应该创建响应的自定义类，并从 (Illuminate\Http\Response, Illuminate\Http\RedirectResponse) 类扩展它。通过这个技巧，您可以发送和处理任何您喜欢的值。祝你好运
