Laravel 此路由不支持GET方法。支持的方法：执行更新和删除时放置和删除

web.php中的代码

Route::group(['middleware'=>['auth','admin']], function(){
    Route::put('/role-register-update/{id}', 'Admin\DashboardController@registerupdate');
    Route::delete('/role-delete/{id}', 'Admin\DashboardController@registerdelete');
});

仪表板控制器中的代码

namespace App\Http\Controllers\Admin;

use App\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class DashboardController extends Controller
{

    public function registerupdate(Request $request, $id){
        $user = User::find($id);
        $user->name = $request->input('name');
        $user->phone = $request->input('phone');
        $user->email = $request->input('email');
        $user->userType = $request->input('userType');
        $user->update();
        return \redirect('/user_profile')->with('success', 'Your Data Is Updated');
    }

    public function registerdelete($id){
        $user = User::findOrfail($id);
        $user->delete();
        return \redirect('/user_profile')->with('success', 'Your Data Is Deleted');
    }
}

编辑表格代码

<form action="/role-register-update/{{ $user->id }}" method="POST">
                            {{ @csrf_field() }} {{ @method_field('PUT') }}
                            <div class="form-group">
                                <label for="name">Name</label>
                                <input type="text" class="form-control" name="name" id="name" placeholder="Full Name" value="{{ $user->name }}">
                            </div>
                            <div class="form-group">
                                <label for="phone">Phone</label>
                                <input type="number" class="form-control" name="phone" id="phone" placeholder="Phone Number" value="{{ $user->phone }}">
                            </div>
                            <div class="form-group">
                                <label for="email">Email</label>
                                <input type="email" class="form-control" name="email" id="email" aria-describedby="emailHelp" placeholder="Email Id" value="{{ $user->email }}">
                            </div>
                            <div class="form-group">
                                <label for="role">Role</label>
                                <select name="userType" class="form-control" id="userType">
                                    <option value="">--- Select ---</option>
                                    <option value="admin">Admin</option>
                                    <option value="user">Internal User</option>
                                </select>
                            </div>
                            <div class="form-group">
                                <div class="row">
                                    <div class="col-md-6">
                                        <button type="button" class="btn btn-outline-success">Submit</button>
                                    </div>
                                    <div class="col-md-6">
                                        <a href='../user_profile' class="btn btn-outline-warning">Cancel</a>
                                    </div>
                                </div>
                            </div>
                        </form>

删除表单数据的代码

<form method="POST" action="/role-delete/{{ $user->id }}">
                                        {{ csrf_field() }} {{ method_field('DELETE') }}
                                        <button type="button" class="btn btn-outline-danger">Danger</button>
                                    </form>

更新和删除操作未在Laravel 5.8中的本地主机上执行。 它会抛出更新失败的错误- 此路由不支持GET方法。支持的方法：PUT

&删除时出现相同错误 此路由不支持GET方法。支持的方法：删除

我没有得到解决方案，请帮助

以获得正确的表单功能，您的按钮应具有提交类型

即以表格形式更新

<button type="submit" class="btn btn-outline-success">Submit</button>

但同样，从编程和维护的角度来看，最好和正确的方法是使用命名路由

 <a href='{{ route('route.name.set.in.routes.web.file') }}' class="btn btn-outline-warning">Cancel</a>

---

改为设置type=submit。谢谢：它现在可以正常工作，更新和删除功能良好。你们可以接受并投票支持我留下的答案。我还提到了代码中的另一件事。

<a href='/user_profile' class="btn btn-outline-warning">Cancel</a>

 <a href='{{ route('route.name.set.in.routes.web.file') }}' class="btn btn-outline-warning">Cancel</a>
