Laravel POST令牌不匹配异常(文件上传)

Laravel POST Token missmatch exception (file upload)

本文关键字：文件 异常 POST 令牌 不匹配 Laravel | 更新日期: 2023-09-26

我有一个功能，创建一个有一点响应它(这是有效的)，我有这个html代码，这是我的弹出框(它使用jquery对话框来显示弹出但表单只是在我的其他html代码之间，由一个div包围，使其不可见):

<form id="logform" method="POST"> 
<select id='logoption'>  
<option value="0"> Select logtype </option>
<?php 
//SQL in laravel style to get log types from database
$logtypes = DB::table('time_log_types')->get();
foreach ($logtypes as $logtype)
{
echo ' <option value="'. $logtype->id . '">' . $logtype->logtype.'</option>';
}
?>
</select>
<div id="illness" style="display:none">
<p>End date: <input type="text" id="enddate"></p>
<p>Doctor's note: <input type="file" id="doctorsnote"></p>                                            
</div>                                           
<input type="button" value="submit" id="submitbutton" style="display:none" />
</form>

这个弹出框中的提交按钮是这样做的(使用jquery):

<script>
$(document).ready(function() {
    //File upload
$('#submitbutton').on('click', function() {
            var fd = new FormData(document.getElementById("logform"));
//fd.append("CustomField", "This is some extra data");
            $.ajax({
                url: ' ',
                type: 'POST',
                data: fd,                
                cache: false,
                contentType: false,
                processData: false
            });
        });
    });
</script>

我确保我的POST实际上是通过在我的routes.php中添加此路由到正确的地方(我知道我张贴到正确的地方，因为我在firefox中使用Inspect元素时检查了网络选项卡):

Route::post('calendar', 'LogController@upload');

最后这是我在LogController中的代码:

<?php namespace App'Http'Controllers;
use Input;
class LogController extends Controller {
    public function upload() {       
        $file = Input::file('doctorsnote');
        $destinationPath = 'C://xampp/htdocs/proofofconcept/savedImages';
        // If the uploads fail due to file system, you can try doing public_path().'/uploads' 
        $filename = str_random(12);
        //$filename = $file->getClientOriginalName();
        //$extension =$file->getClientOriginalExtension(); 
        $upload_success = $file->move($destinationPath, $filename);
        if( $upload_success ) {
           return Response::json('success', 200);
        } else {
           return Response::json('error', 400);
        }
    }
}

问题是当我点击提交按钮时，我得到一个500响应，我记录了这个错误消息，但我不知道该怎么处理它:

我完全不知道发生了什么，我根据周围的指导创建了这段代码，据我所知，这应该是工作的但我对这一切都是新手，我真的需要一些帮助来弄清楚

编辑:我添加了一个新的字段到我的表单，包括csrf令牌，像这样: 
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">

现在我得到了不同的堆栈跟踪:

编辑:我将我的端点上传到不同的控制器，它现在工作得很好，但是现在它抱怨我的Input::file('doctorsnote')是一个非对象:

[2015-05-15 11:35:20] local.ERROR: exception 'Symfony'Component'Debug'Exception'FatalErrorException' with message 'Call to a member function move() on a non-object' in C:'xampp'htdocs'proofofconcept'laravel'app'Http'Controllers'CalendarController.php:27
Stack trace:
#0 {main}

编辑:我现在有了这个表单但是它没有注册当我点击提交按钮时，POST没有被执行

<form id="logform" enctype="multipart/form-data" action="calendar"  method="POST"> 
<select id='logoption'>  
<option value="0"> Select logtype </option>
<?php 
//SQL in laravel style to get log types from database
$logtypes = DB::table('time_log_types')->get();    
foreach ($logtypes as $logtype)
{
echo ' <option value="'. $logtype->id . '">' . $logtype->logtype.'</option>';
}
?>
 </select>
<div id="illness" style="display:none">
<p>End date: <input type="text" id="enddate"></p>
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
<p>Doctor's note: <input type="file" name="doctorsnote" id="doctorsnote"/></p>                                            
                                            </div>                                            
<input type="button" value="submit" id="submitbutton" style="display:none" />
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
</form>

我刚刚上传了一个文件:D我是怎么做的:

第一步:像这样编辑我的表单:-添加了enctype，添加了一个动作到我的形式，添加了方法后增加了csrftoken的隐藏字段-删除所有javascript相关的提交我的表单(不需要这个ajax调用)

<form id="logform" enctype="multipart/form-data" action="calendar"  method="post"> 
<select id='logoption'>  
<option value="0"> Select logtype </option>
<?php 
//SQL in laravel style to get log types from database
$logtypes = DB::table('time_log_types')->get();
foreach ($logtypes as $logtype)
{
echo ' <option value="'. $logtype->id . '">' . $logtype->logtype.'</option>';
}
?>
</select>
<div id="illness" style="display:none">
<p>End date: <input type="text" name="enddate" id="enddate"></p>
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
<p>Doctor's note: <input type="file" name="doctorsnote" id="doctorsnote"/></p>                                            
</div>    
<input type="button" value="submit" id="submitbutton" style="display:none" onclick="submit()" />
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
</form>

步骤2:删除javascript

步骤3:将上传功能移动到我的calendarController中，并将路由更改为:

Route::post('calendar', 'CalendarController@upload');

我没有改变任何其他(除了删除整个javascript函数)

，它像一个魅力，花了我一整天的时间让它工作，但我想这对一个完全的新手来说是不错的:D

清空包括cookie在内的浏览器缓存。Ctrl+Refresh表单页面。请重试。

编辑:

只需在表单中包含此元素即可。

<input type="hidden" name="_token" value="{{ csrf_token() }}">
