路由模型为租户前缀Route::resource()绑定多个参数

Question

我正在使用 Laravel 的 Resource Controllers 功能开发 API，并将 Orchestral Multi-tenant Database Schema Manager 用作单一数据库。

在我的控制方法中，我使用 Route Model Binding 将模型 ID 注入到路由或控制器操作中，经常查询以检索与该 ID 对应的模型。

我的 API 中的一些相关路由：

| POST      | api/v1/{tenant}/fornecedores                     | store  | App\Http\Controllers\Api\Fornecedor\FornecedorController@store  | api,tenant,jwt.auth |
| GET|HEAD  | api/v1/{tenant}/fornecedores                     | index  | App\Http\Controllers\Api\Fornecedor\FornecedorController@index  | api,tenant,jwt.auth |
| GET|HEAD  | api/v1/{tenant}/fornecedores/count               |        | App\Http\Controllers\Api\Fornecedor\FornecedorController@count  | api,tenant,jwt.auth |
| PUT|PATCH | api/v1/{tenant}/fornecedores/{fornecedor}        | update | App\Http\Controllers\Api\Fornecedor\FornecedorController@update | api,tenant,jwt.auth |
| GET|HEAD  | api/v1/{tenant}/fornecedores/{fornecedor}        | show   | App\Http\Controllers\Api\Fornecedor\FornecedorController@show   | api,tenant,jwt.auth |
| GET|HEAD  | api/v1/{tenant}/fornecedores/{fornecedor}/audits |        | App\Http\Controllers\Api\Fornecedor\FornecedorController@audits | api,tenant,jwt.auth |
...

我的 API 路由文件示例：

// API V1
Route::group(['prefix' => 'v1/{tenant}', 'middleware' => 'tenant'], function () {

    // Fornecedores
    Route::group(['prefix' => 'fornecedores'], function () {
        Route::get('count', 'Api\Fornecedor\FornecedorController@count');
        Route::get('{fornecedor}/audits', 'Api\Fornecedor\FornecedorController@audits');

        Route::resource('/', 'Api\Fornecedor\FornecedorController', [
            'parameters' => ['' => 'fornecedor'],
            'except' => ['create', 'edit', 'destroy']
        ]);
    });
});

这些是我的FornecedorController.php的一些方法：

public function index()
{
    return $this->fornecedorService->getFornecedoresPaginate();
}

// This is line 48 (throw below):
public function show(Fornecedor $fornecedor)
{
    return $fornecedor;
}

但是，当尝试访问使用路由模型绑定的 URL 时，我收到以下错误：

网址： /api/v1/1/fornecedores/1

FatalThrowableError in FornecedorController.php line 48:
Type error: Argument 1 passed to App\Http\Controllers\Api\Fornecedor\FornecedorController::show() must be an instance of App\Models\Fornecedor, string given

这是所有的痕迹：

in FornecedorController.php line 48
at FornecedorController->show('1', object(Fornecedor))
at call_user_func_array(array(object(FornecedorController), 'show'), array('tenant' => '1', 'fornecedor' => object(Fornecedor))) in  Controller.php line 55
at Controller->callAction('show', array('tenant' => '1', 'fornecedor' => object(Fornecedor))) in ControllerDispatcher.php line 44
at ControllerDispatcher->dispatch(object(Route), object(FornecedorController), 'show') in Route.php line 203
at Route->runController() in Route.php line 160
at Route->run() in Router.php line 559
at Router->Illuminate\Routing\{closure}(object(Request)) in Pipeline.php line 30
at Pipeline->Illuminate\Routing\{closure}(object(Request)) in GetUserFromToken.php line 46
at GetUserFromToken->handle(object(Request), object(Closure)) in
...

我可以验证在检索参数时显然存在混淆。检查路由参数时，结果如下：

public function show($fornecedor)
{
    dd(\Route::current()->parameters());
}

网址：/api/v1/1/fornecedores/18

结果：

array:2 [
  "tenant" => "1"
  "fornecedor" => "18"
]

当尝试检索提供者的路由时：

public function show($fornecedor)
{
    dd($fornecedor);
}

网址：/api/v1/1/fornecedores/18

结果：

"1"

即使使用绑定我得到的参数也不正确。并且其他不使用第二个参数的路由都可以。

谁能告诉我更好的方法？

谢谢！

第一个猜测是你试图隐式绑定 fornecedor 参数，而 Laravel 无法解析或识别它。

您可以在路由文件（routes/web.php 或 routes.php）的下方某处声明参数-模型关系

Route::model('fornecedor', \App\Models\ Fornecedor::class);

您的show 方法也不适合tenent 参数。该方法应如下所示：

public function show($tenant, Fornecedor $fornecedor){
    return $fornecedor;
}

或

public function show(Tenant $tenant, Fornecedor $fornecedor){
    return $fornecedor;
}
