Laravel API 仅适用于特定路由，其他会抛出 404 错误答案

【问题标题】：Laravel API only works on a specific route, others throw a 404 errorLaravel API 仅适用于特定路由，其他会抛出 404 错误

【问题描述】：

更新：运行php artisan route:clear 解决了这个问题，但只是部分解决了。在我运行命令并成功使用 API 后，我调用的路由再次从路由列表缓存中消失，它迫使我再次运行命令。我不知道为什么会这样。

我正在尝试使用我设置的 Laravel API，但由于某种原因我只能使用三个可用路由之一，另外两个丢弃 404。

Route::post('/login', 'API\UserController@login'); //this works

Route::group(['middleware' => ['auth:api']], function () {
    Route::post('/roles/all', 'API\RoleController@getAll'); //this doesn't work - error 404
    Route::post('/permissions/all', 'API\PermissionController@getAll'); //this doesn't work - error 404
});

路由指向正确的位置，函数存在，并且我通过 Postman 进行的调用具有正确的参数（url 示例：'http://localhost:8000/api/roles/all'、GET 调用、授权字段中的身份验证令牌）。

我将路由放在中间件内部还是外部也没关系（以防它与 oauth2 令牌或中间件本身有问题有关）。

这是我尝试调用的函数之一的示例：

public function getAll()
{
    $role = Role::all();
    return response()->json(['role' => $role], 200);
}

编辑：这是 php artisan route:list 的输出

【问题讨论】：

在终端运行php artisan route:list，查看可用路线列表
你能用命令的输出更新你的问题吗：php artisan route:list
完成，当登录出现时，输出中似乎缺少两条路由。
那你明白为什么它会返回 404。所有路由都在同一个路由文件中吗？另外，如果出现丢失的路由，请执行php artisan route:clear 并再次运行 list 命令
php artisan route:clear 成功了，它们现在出现在路线列表中，我可以使用它们！您能否将此作为答案发布，以便我进行验证？

标签： laravel api

【解决方案1】：

新路由丢失可能是因为 Laravel 正在为缓存的路由提供服务。验证这一点的一种快速方法是运行php artisan route:list。

如果路线不存在，则证实了该理论。解决方案是运行 php artisan route:clear 告诉 laravel 清除路由缓存，以便可以从路由文件中重新获取路由。

之后，再次运行php artisan route:list。丢失的路线现在应该会显示出来并且可以访问。

【讨论】：

好的，这可以解决问题，但发生了一些奇怪的事情。在使用 API 后，它从 route:list 中消失，我必须再次清除它才能显示并再次使用它，然后循环重复。为什么会这样？
这很奇怪。请问你用的是什么版本的laravel？我怀疑 laravel 望远镜包
除了缓存问题之外，最好将标头中的令牌作为授权密钥传递。
我使用的是 Laravel 6.13.1 版，是的，我在授权字段中传递了令牌。 OP上写错了，谢谢指出。
我不确定可能是什么问题。运行，php artisan route:clear，然后是php artisan route:cache。现在，如果两次都能正常工作，请尝试使用两次 API
