根据记录的用户字段，在哪里切换到其他服务？
根据记录的用户字段，在哪里切换到其他服务？
提问于 2022-11-10 06:13:45
在laravel 9应用程序中，我尝试切换到不同的服务。
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* @return void
*/
public function register()
{
if ($this->app->environment('local')) {
$this->app->register(\Laravel\Telescope\TelescopeServiceProvider::class);
$this->app->register(TelescopeServiceProvider::class);
$this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
}
// Error pointing at this line
$loggedUser = Auth::user();
if( $loggedUser->membership_mark === 'G') { // G=>Gold Membership
$this->app->bind('App\Interfaces\PageMembershipMarkStrategyInterface',
'App\Implementations\PageGoldMemberStrategy');
}
}但我错了：
Target class [hash] does not exist. in...看起来，当我需要登录用户时，注册方法并不适合于app->bind。但我要把这个绑在哪里呢？在自定义服务提供商中？我是中间件？
修改块: --我使用命令创建了一个中间件：
php artisan make:middleware SetPageMembershipMarkService在app/Http/Kernel.php中，我添加了以下内容：
protected $routeMiddleware = [
'auth' => \App\Http\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
// I added this line :
\App\Http\Middleware\SetPageMembershipMarkService::class,
'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,但我错了：
Illuminate\Contracts\Container\BindingResolutionException: Target [App\Interfaces\PageMembershipMarkStrategyInterface] is not instantiable while building [App\Http\Controllers\InformOnPageInStockController]....我不确定必须在Kernel.php的哪个位置添加ref到PageMembershipMarkStrategyInterface？检查日志.我的SetPageMembershipMarkService似乎没有在出错前触发.
修改后的区块2:
在文件app/Http/Kernel.php中，我添加了中间件引用：
protected $routeMiddleware = [
'auth' => \App\Http\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
// I set it AFTER auth
'setPageMembership' =>\App\Http\Middleware\SetPageMembershipMarkService::class,
'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
'can' => \Illuminate\Auth\Middleware\Authorize::class,
'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
'password.confirm' => \Illuminate\Auth\Middleware\RequirePassword::class,
'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,
'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
'verified' => \Illuminat`enter code here`e\Auth\Middleware\EnsureEmailIsVerified::class,
];abd in routes/api.php：
Route::middleware('auth:api')->prefix('v1') /*->name('api.v1')*/ ->group(function () {
Route::get('/user', function (Request $request) {
return $request->user();
});
...
Route::middleware(['setPageMembership'])->group(function () {
Route::resource('/inform-on-page-in-stock', InformOnPageInStockController::class)->except(['edit', 'add']);
});我仍然有错误：
Illuminate\Contracts\Container\BindingResolutionException: Target [App\Interfaces\InformOnPageInStockStrategyInterface] is not instantiable while building [App\Http\Controllers\InformOnPageInStockController]. - 检查日志我找不到在SetPageMembershipMarkService中间件中设置的日志消息，因此看起来它没有在控制器之前设置.怎么了?
你提到的
- 使用RouteServiceProvider。哪个语法正确?
文件app/Http/Middleware/SetPageMembershipMarkService.php有以下几行：
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
use Auth;
class SetPageMembershipMarkService
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse) $next
* @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse
*/
public function handle(Request $request, Closure $next)
{
$loggedUser = Auth::user();
\Log::info(varDump($loggedUser, ' -1 SetPageMembershipMarkService $loggedUser::'));
$membershipMark = $loggedUser->membership_mark;
if( $membershipMark === 'S') { // G=>Silver Membership
app()->bind('App\Interfaces\InformOnPageInStockStrategyInterface',
'App\Implementations\HasNoInformOnPageInStockStrategy');
}
if( $membershipMark === 'G') { // G=>Gold Membership
app()->bind('App\Interfaces\InformOnPageInStockStrategyInterface',
'App\Implementations\InformOnPageInStockGoldMembersStrategy');
}
return $next($request);
}
}但是在日志文件中我没有看到在这个中间件中有任何日志消息..。
谢谢!

您将无法在Service中获取Auth:user()数据。因为服务提供者在Laravel设置Auth数据之前运行，所以您必须使用一些黑客方法来处理它。
我认为处理与auth相关的数据的更好方法应该是在中间件上，而不是在服务提供者中。
在这个问题上可以找到更多的解释，答案是Laravel - How to get current user in AppServiceProvider
修改块的编辑
您的中间件注册是错误的。
$routeMiddleware此数组用于注册自定义中间件，您将使用该中间件并手动定义
例如：
protected $routeMiddleware = [
.....
// I added this line :
'setPageMembership' => \App\Http\Middleware\SetPageMembershipMarkService::class,然后在路由组中使用这个中间件，如：
Route::middleware(['auth', 'setPageMembership'])->group(function () {
Route::get('test', [TestController::class, 'test']);
});如果您希望中间件为所有路由运行，最好将其添加到$middleware数组中，或者如果您希望在特定的路由组(web/api)中运行，则在$middlewareGroups单个web和api数组中添加它。
如果您希望每个路由都有中间件，那么在RouteServiceProvder中添加中间件也是有效的。
但是，对于用例，在绑定之前需要进行身份验证。因此，在执行这些绑定操作之前，需要先启动auth中间件。因此，将中间件添加到您的路由文件中，如我前面所示，对于您的用例来说就足够了。
