Lumen：在 routes.php 第 17 行：升级到 5.5 后调用未定义的方法 Laravel\Lumen\Application::post()。*

Question

我正在从事需要将 Lumer 版本从 5.1.* 升级到 7.* 的项目。

但我一直停留在5.4.* 和5.5.* 版本。在5.4.* 中运行内置php 服务器php -S localhost:8000 -t ./public 并访问URL http:\\localhost:8000 时，出现以下错误：

Call to undefined method ...\Application->welcome()

但我升级到下一个版本希望能解决这个问题，因为我没有更改vendor 文件夹之外的任何文件。

但是在我升级到 Lumen 5.5.* 版本之后，现在当我运行任何 php artisan 命令时，我收到以下错误：

In routes.php line 17:
  Call to undefined method Laravel\Lumen\Application::post()

谁能分享一下问题出在哪里以及如何解决上述两个错误？

这是项目的 composer.json 文件，以防万一：

//$app->group(['middleware' => 'FilterInput'], function($app) {

    $app->post('app_details', ['as' => 'app_details', 'uses' => 'App\Http\Controllers\Details@set_app_details']);
    $app->post('phone_details', ['as' => 'phone_details', 'uses' => 'App\Http\Controllers\Details@set_phone_details']);

    $app->post('survey', ['as' => 'survey', 'uses' => 'App\Http\Controllers\Survey@set_data']);


    //capture all routes regardless
    $app->get('{path:.*}', function() use ($app) {
        return $app->welcome();
    });

//});

bootstrap/app.php摘录：

...
...
require __DIR__.'/../app/Http/routes.php';

return $app;

如您所见，here $app 已不再使用，而是使用 $router。

$router->get('/', function () use ($router) {
    return $router->app->version();
});

以前的版本是this

通过将$app 替换为$router 来更新路由后； bootstrap/app.php变成了这样

$app->router->group(['namespace' => 'App\Http\Controllers'], function ($router) {
    require __DIR__ . '/../app/Http/routes.php';
});
