【问题描述】：

在我的 Laravel-5.8 中，我要上传图片

Http\Controllers\HomeController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Models\Hr\HrEmployee;
use App\Http\Requests\Hr\Employee\UploadPictureRequest;

class HomeController extends Controller
{

public function update_picture(UploadPictureRequest $request, $id)
{
    DB::beginTransaction();         
    try{ 
    $employee = HrEmployee::find($id);
             if ($request->emp_image != "") {
                 $emp_image = $request->file('emp_image');
                 $new_name = rand() . '.' . $emp_image->getClientOriginalExtension();
                 $emp_image->move(public_path('storage/employees/image'), $new_name);
                 $employee->emp_image = $new_name;
            }        
    $employee->save();


    DB::commit();

            Session::flash('success', 'Picture Successfully Uploaded');
            return redirect()->route('dashboard');

    } 
    catch (Exception $exception) 
    {

    DB::rollback();
        Session::flash('error', 'Action failed!');
        return redirect()->back();   
    }                                                     
 }

}

表单是一个名为dashboard的视图中的模态表单

路线/网络

Route::get('/dashboard', 'HomeController@index')->name('dashboard');

    Route::post('update_picture/{id}', [
        'uses' => 'HomeController@update_picture',
        'as' => 'update_picture'
    ]);

当我提交表单时，我收到了这个错误：

错误：尝试上传图片时出现 403

然后当我做 php artisan route:list 时，我得到了：

|发布 |更新图片/{id} |更新图片 | App\Http\Controllers\HomeController@update_picture |网络，身份验证 |

我该如何解决？

谢谢。

【解决方案1】：

或者你可以试试这个

 Route::put('update_picture/{id}''HomeController@update_picture')->name('update_picture');

【讨论】：

当我这样做时，我得到了错误：405。不允许的方法
你在使用 ajax 吗？
您缺少 <form action="{{route('update_picture',['id'=>$employee->id])}}" method="post" id="update-picture-form" enctype="multipart/form-data"> 形式的 enctype="multipart/form-data"

【解决方案2】：

请在表单标签中添加此 enctype="multipart/form-data"

<form action="{{route('update_picture',['id'=>$employee->id])}}" method="post" id="update-picture-form" enctype="multipart/form-data">

并替换此行$new_name = rand() . '.' . $emp_image->getClientOriginalExtension();
用这条线$new_name = rand() . '.' . $request->emp_image->getClientOriginalExtension();
