获取/发布 web.php 创建/存储路由返回 404

Question

我试图弄清楚为什么我的创建路由返回 404 错误，因为它只给了我一个 Failed to load resource: 服务器响应状态为 404（未找到）页。

显示、编辑和更新路由功能没有问题，并且视图与 create.blade.php 文件位于同一文件夹中。我的 web.php 似乎可以识别控制器中的 create 函数，并且控制器似乎至少可以从 vs code 的 Follow Link 系统中识别 create.blade.php 文件。我也试过清空刀片文件，只留下一个 div、扩展和部分，但仍然收到 404。

web.php

Route::get('/location/{location}', 'LocationController@show')->name('location.show');
Route::get('/location/create', 'LocationController@create');
Route::post('/location', 'LocationController@store');
Route::get('/location/{location}/edit', 'LocationController@edit')->name('location.edit');
Route::patch('/location/{location}', 'LocationController@update')->name('location.update');

位置.php

<?php

namespace App;
use Illuminate\Database\Eloquent\Model;

class Location extends Model
{

    public function casino() {
        return $this->belongsTo(Casino::class);
    }

    public function duties() {
        return $this->hasMany(Duty::class)->orderBy('title', 'ASC');
    }

}

LocationController.php

<?php

namespace App\Http\Controllers;
use App\Location;
use Illuminate\Http\Request;

class LocationController extends Controller
{
    public function create() {
        return view('locations.create');
    }

    public function store() {
        $data = request()->validate([
            'title' => 'required',
        ]);
        return redirect("/casino/" . location()->casino()->id);
    }

    public function edit(Location $location) {
        return view('locations.edit', compact('location'));
    }

    public function update( Request $request, Location $location) {

        $data = request()->validate([
            'title' => 'required'
        ]);

        $location->title = $request->get('title');
        $location->save();

        return redirect("/location/{$location->id}");
    }

    public function show(Location $location) {
        return view('locations.show', compact('location'));
    }

}

create.blade.php

Answer 1

您的路线顺序错误。

由于您的显示路线/location/{location} 位于顶部，它会捕获/location/create 并假设create 是您要查看的位置的路线参数，因此您永远不会到达create 操作而是 show 操作。

将create 路由放在show 路由上方应该可以解决问题：

Route::get('/location/create', 'LocationController@create');
Route::post('/location', 'LocationController@store');
Route::get('/location/{location}', 'LocationController@show')->name('location.show');
Route::get('/location/{location}/edit', 'LocationController@edit')->name('location.edit');
Route::patch('/location/{location}', 'LocationController@update')->name('location.update');

Answer 2

您没有为您的创建路线创建别名。应该是这个？

Route::get('/location/create', 'LocationController@create')->name('location.create');
Route::post('/location', 'LocationController@store')->name('location.store');
