【问题描述】：

我是 Laravel 的新手。我正面临 Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException 此路由不支持 POST 方法。支持的方法：GET、HEAD。 提交表单时出错。请帮我解决。

我的编码是……

student_edit.balde.php

    <!DOCTYPE html>
<html>
<head>
<title>Sample view</title>
<link rel="stylesheet" type="text/css" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
    <form action="images_update" method="post">
        {{ csrf_field() }}
    <div class="container">
        <div class="row">
            <div class="com-md-4">
            <div class="form-group">
                <input type="hidden" name="id" value="{{ $student['id'] }}">
                <label>Name:</label> 
                <input type="text" name="name" placeholder="Enter the name" class="form-control"
                value="{{ $student['name'] }}">
            </div>
            <div class="form-group">
                <label>Email:</label>
                <input type="email" name="email" placeholder="Enter the email" class="form-control"
                value="{{ $student['email'] }}">
            </div>
            <div class="form-group">  
                <label>Mobile:</label>
                <input type="text" name="mobile" placeholder="Enter the mobile number" class="form-control"
                value="{{ $student['mobile'] }}">
            </div>
            <div class="form-group"> 
                <input class="btn btn-success" type="submit" name="submit" value="Update">
            </div>
        </div>
    </div>
    </div>
    
</form>

*/

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

use App\Http\Controllers\TestController;

Route::get('/images', [TestController::class, 'index']);
Route::post('/images', [TestController::class, 'store']);
Route::get('/images/{id}', [TestController::class, 'show']);
Route::post('/images_update', [TestController::class, 'update']);

【问题讨论】：

尝试将action="images_update" 更改为action="/images_update"。
这能回答你的问题吗？ The POST method is not supported for this route. Supported methods: GET, HEAD. Laravel

【解决方案1】：

如上所述，尝试将表单操作行更改为以下内容：

<form action="/images_update" method="post">

还请注意，您可以在 Laravel 中使用 Named Routes（我在下面提供了它们的用法示例）。这些为您提供了对路由助手的访问，这将避免您手动输入每个页面的 URL。
