控制器

Question

当我尝试使用ImagesController定义我的路线时，我得到一个＆＃34;网站重定向了你太多次＆＃34;什么时候应该是索引时出错。我很难过。我是否过度疲劳而没有看到明显的东西？

web.php

Route::prefix('images')->group(function(){
    Route::post('add-tag', 'ImagesController@addTag');
    Route::get('test', 'ImagesController@index');
});

当我访问/images/test时，控制器会正确响应。当我将其定义为'' 或 /时，它会重定向太多。 我没有同时设置它们。

Route::prefix('images')->group(function(){
    Route::post('add-tag', 'ImagesController@addTag');
    // like this:
    Route::get('', 'ImagesController@index');
    // or like the following: 
    Route::get('/', 'ImagesController@index');
});

我甚至试图在前缀组之前定义/ images无济于事。 images/test在这种情况下很好。

Route::get('images', 'ImagesController@index');
Route::prefix('images')->group(function(){
    Route::post('add-tag', 'ImagesController@addTag');
    Route::get('test', 'ImagesController@index');
});

因为我有一个名为Images implicit binding的模型干扰了我为名为ImagesController的控制器定义的路由，并应用了前缀/images。将路由中的名称更改为image后，此问题就消失了。
