Laravel 5.5 ajax call 419 (unknown status)
提问by Chris
I do an ajax call but I keep getting this error:
我做了一个ajax调用，但我一直收到这个错误：
419 (unknown status)
419（未知状态）
No idea what is causing this I saw on other posts it has to do something with csrf token but I have no form so I dont know how to fix this.
不知道是什么导致了这个我在其他帖子上看到它必须用 csrf 令牌做一些事情但我没有表格所以我不知道如何解决这个问题。
my call:
我的电话：
$('.company-selector li > a').click(function(e) {
e.preventDefault();
var companyId = $(this).data("company-id");
$.ajax({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
url: '/fetch-company/' + companyId,
dataType : 'json',
type: 'POST',
data: {},
contentType: false,
processData: false,
success:function(response) {
console.log(response);
}
});
});
My route:
我的路线：
Route::post('fetch-company/{companyId}', 'HomeController@fetchCompany');
My controller method
我的控制器方法
/**
* Fetches a company
*
* @param $companyId
*
* @return array
*/
public function fetchCompany($companyId)
{
$company = Company::where('id', $companyId)->first();
return response()->json($company);
}
The ultimate goal is to display something from the response in a html element.
最终目标是在 html 元素中显示响应中的某些内容。

Use this in the head section:
在 head 部分使用它：
<meta name="csrf-token" content="{{ csrf_token() }}">
and get the csrf token in ajax:
并在ajax中获取csrf令牌：
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
Please refer Laravel Documentation csrf_token
请参考 Laravel 文档csrf_token

Another way to resolve this is to use the _tokenfield in ajax data and set the value of {{csrf_token()}}in blade. Here is a working code that I just tried at my end.
解决此问题的另一种方法是使用_tokenajax 数据中的字段并设置{{csrf_token()}}刀片中的值。这是我刚刚尝试过的工作代码。
$.ajax({
type: "POST",
url: '/your_url',
data: { somefield: "Some field value", _token: '{{csrf_token()}}' },
success: function (data) {
console.log(data);
},
error: function (data, textStatus, errorThrown) {
console.log(data);
},
});

This is similar to Kannan's answer. However, this fixes an issue where the token should not be sent to cross-domain sites. This will only set the header if it is a local request.
这类似于 Kannan 的回答。但是，这解决了不应将令牌发送到跨域站点的问题。如果它是本地请求，这只会设置标头。

use this in your page
在您的页面中使用它
<meta name="csrf-token" content="{{ csrf_token() }}">
and in your ajax used it in data:
并在您的 ajax 数据中使用它：
_token: '{!! csrf_token() !!}',
that is:
那是：
$.ajax({
url: '/fetch-company/' + companyId,
dataType : 'json',
type: 'POST',
data: {
_token: '{!! csrf_token() !!}',
},
contentType: false,
processData: false,
success:function(response) {
console.log(response);
}
});
Thanks.
谢谢。

It's possible your session domain does not match your app URL and/or the host being used to access the application.
您的会话域可能与您的应用程序 URL 和/或用于访问应用程序的主机不匹配。
1.) Check your .env file:

就我而言，我忘记将 csrf_token 输入添加到提交的表单中。所以我做了这个 HTML：
<form class="form-material" id="myform">

if(!l_img) {

Even though you have a csrf_token, if you are authenticate your controller actions using Laravel Policiesyou can have 419 response as well. In that case you should add necessary policy functions in your Policyclass.
即使您有一个csrf_token，如果您使用 Laravel 验证您的控制器操作，Policies您也可以获得 419 响应。在这种情况下，您应该在Policy类中添加必要的策略函数。

If you are loading .js from a file you have to set a variable with the csrf_token in your "main" .blade.php file where you are importing the .js and use the variable in your ajax call.
如果您从文件加载 .js，则必须在“主”.blade.php 文件中使用 csrf_token 设置一个变量，您将在其中导入 .js 并在 ajax 调用中使用该变量。
index.blade.php
index.blade.php
...
...
<script src="{{ asset('js/anotherfile.js') }}"></script>
<script type="text/javascript">
var token = '{{ csrf_token() }}';
</script>
anotherfile.js
另一个文件.js
$.ajax({
url: 'yourUrl',
type: 'POST',
data: {
'_token': token
},
dataType: "json",
beforeSend:function(){
//do stuff
},
success: function(data) {
//do stuff
},
error: function(data) {
//do stuff
},
complete: function(){
//do stuff
}
});

just serialize the form data and get your problem solved.
只需序列化表单数据即可解决您的问题。
data: $('#form_id').serialize(),
