Laravel PUT 方法错误：路由不支持 PUT 方法

Question

当我尝试更新学生记录时，我的 Laravel 应用程序中的 PUT 方法遇到了问题。每当我尝试发出 PUT 请求来更新学生信息时，我都会收到以下错误消息：路线 Students/10/edit 不支持 PUT 方法。支持的方法：GET、HEAD。

这是（blade php）edit-comments.blade.php

    <div class="card-body">
                        <form method="POST" action="{{ route('students.edit', $student->id) }}">

学生控制器

public function edit($id)
    {
        $student = Student::findOrFail($id);
        return view('students.edit', compact('student'));
    }


public function update(Request $request, $id)
{
    $request->validate([
        'name' => 'required',
        'email' => 'required',
        'phone_number' => 'required',
        'address' => 'required',
        'age' => 'required',
    ]);
    $student = Student::findOrFail($id);
    $student->update([
        'name' => $request->input('name'),
        'email' => $request->input('email'),
        'phone_number' => $request->input('phone_number'),
            'address' => $request->input('address'),
        'age' => $request->input('age'),


    ]);
    return redirect()->back()->with('status', 'Student updated successfully');

}

使用的路由

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\StudentController;

Route::resource('students', StudentController::class);

和路线：列表

      POST            _ignition/execute-solution ............................................ ignition.executeSolution › Spatie\LaravelIgnition › ExecuteSolutionController
  GET|HEAD        _ignition/health-check ........................................................ ignition.healthCheck › Spatie\LaravelIgnition › HealthCheckController  
  POST            _ignition/update-config ..................................................... ignition.updateConfig › Spatie\LaravelIgnition › UpdateConfigController

  GET|HEAD        sanctum/csrf-cookie ............................................................... sanctum.csrf-cookie › Laravel\Sanctum › CsrfCookieController@show

  GET|HEAD        students/{student}/edit ...................................................................................... students.edit › StudentController@edit

Answer 1

问题出在表单动作上。由于您要更新学生记录，因此表单操作应指向 StudentController 中的更新方法，而不是编辑方法。表单的正确操作应该是students.update路线而不是students.edit。
