找不到Laravel 404

我对“ 404 |未找到”有疑问。路线存在,但是我仍然有问题。

我已经尝试过:

php artisan route:list

这条路线确实存在。

web.php:

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/p/create', 'PostsController@create');
Route::get('/p/{post}', 'PostsController@show'); 
Route::post('/p', 'PostsController@store');

Route::get('/profile/{user}', 'ProfilesController@index')->name('profile.show');
Route::get('/profile/{user}/edit', 'ProfilesController@edit')->name('profile.edit'); //this shows the form of edit profile
Route::patch('/profile/{user}', 'ProfilesController@update')->name('profile.update'); //this will actually do the process of updating our profile

ProfilesController.php:

public function edit(User $user)
{
    return view('profiles.edit', compact('user'));
}

public function update(User $user){ //some validation
        $data =request()->validate([
            'title' => 'required',
            'description' => 'required',
            'url' => 'url', //require the http://
            'image' => '',
        ]);

        auth()->user()->profile->update($data); //auth() is a protection. Without this, an external user, for example in incognite, can edit the profile
    }

edit.blade.php:

@extends('layouts.app')

@section('content')
<div class="container">
<form action="/profile->{{ $user->id }}" enctype="multipart/form-data" method="POST">
        @csrf
        @method('PATCH') <!--it's not permitted write method = 'patch', by default it will be get-->
            <div class="row">
                    <div class="col-8 offset-2">

                        <div class="row">
                            <h2>Edit Profile</h2>
                        </div>
                        <div class="form-group row">
                            <label for="title" class="col-md-4 col-form-label">Title</label>
                                    <input id="title"
                                           type="text" 
                                           class="form-control @error('title') is-invalid @enderror"  
                                           name="title"
                                           value="{{ old('title') ?? $user->profile->title }}" 
                                           autocomplete="title" autofocus>

                                    @error('title')
                                        <span class="invalid-feedback" role="alert">
                                            <strong>{{ $message }}</strong>
                                        </span>
                                    @enderror
                            </div>

index.blade.php:

                <div class = "pr-5"><strong>212</strong> following</div>
            </div>  
        <div class = "pt-4 font-weight-bold">{{ $user->profile->title }}</div> 
        <div>{{ $user->profile->description }}</div> 
        <div><a href="#">{{ $user->profile->url }}</a></div>
        </div>
    </div>
    <div class="row pt-5">
        @foreach($user->posts as $post)
            <div class="col-4 pb-4">
            <a href="/p/{{ $post->id }}">
                <img src="/storage/{{ $post->image }}" class = "w-100">
            </a>
            </div>
        @endforeach
    </div>
</div>
@endsection

错误仅是“ 404 |未找到”。当我单击编辑按钮时,地址变为:“ http://localhost:8000/profile-> 1”,并且错误可能存在。

首先,问题在于您生成的网址无效。

#include <iostream> #include <string> #include <vector> using namespace std; void strTOvec(string x, vector<string> y) { for (int i = 0; i < strlen(x.c_str()); i++) { y.push_back(x[i]); } } void main() {} 将生成/profile->{{ $user->id }},但/profile->1不能是URL的一部分。通常,您可以通过执行->来解决此问题。

但是我建议您使用Laravel的URL生成器助手来生成URL。

例如:/profile/{{ $user->id }}应该是:

<form action="/profile->{{ $user->id }}"

提醒一下,这里有3个主要的路线助手:

<form action="{{ route('profile.update', [ 'user' => $user->id ])}}"

url('/relative/path'); // Will generate an absolute URL to your app based on a relative URL action('Controller@action'); // Will generate a URL which calls the specified controller route('route.name'); // Will generate a URL based on the named route 中的第二个参数将填写所需的路线参数。

问题是您尝试访问的网址! 根据您的路线web.php,您应该访问“ http://localhost:8000/profile/1”。
