Laravel 419 post error is usually related with api.php and token authorization
Laravel 419 post 错误通常与 api.php 和 token 授权有关
Laravel automatically generates a CSRF "token" for each active user session managed by the application. This token is used to verify that the authenticated user is the one actually making the requests to the application.
Laravel 会为应用程序管理的每个活动用户会话自动生成一个 CSRF “令牌”。此令牌用于验证经过身份验证的用户是否是实际向应用程序发出请求的用户。
Add this to your ajax call
将此添加到您的 ajax 调用中
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
or you can exclude some URIs in VerifyCSRF token middleware
或者您可以在 VerifyCSRF 令牌中间件中排除一些 URI
protected $except = [
'stripe/*',
];

419 error happens when you don`t post csrf_token. in your post method you must add this token along other variables.
当您不发布 csrf_token 时会发生 419 错误。在您的 post 方法中，您必须将此标记与其他变量一起添加。

You don't have any data that you're submitting! Try adding this line to your ajax:
您没有要提交的任何数据！尝试将此行添加到您的 ajax：
data: $('form').serialize(),
Make sure you change the name to match!
确保更改名称以匹配！
Also your data should be submitted inside of a form submit function.
此外，您的数据应该在表单提交功能内提交。
Your code should look something like this:
您的代码应如下所示：
<script>
$(function () {
$('form').on('submit', function (e) {
e.preventDefault();
$.ajax({
type: 'post',
url: 'company.php',
data: $('form').serialize(),
success: function () {
alert('form was submitted');
}
});
});
});

I had the same issue, and it ended up being a problem with the php max post size. Increasing it solved the problem.

In laravel you can use view render. ex. $returnHTML = view('myview')->render(); myview.blade.php contains your blade code
在 Laravel 中，您可以使用视图渲染。前任。$returnHTML = view('myview')->render(); myview.blade.php 包含您的刀片代码

In your action you need first to load companies like so :
在您的操作中，您首先需要像这样加载公司：
$companies = App\Company::all();
return view('listing.company')->with('companies' => $companies)->render();
This will make the companies variable available in the view, and it should render the HTML correctly.
这将使公司变量在视图中可用，并且应该正确呈现 HTML。
Try to use postman chrome extension to debug your view.
尝试使用 postman chrome 扩展来调试您的视图。

You may also get that error when CSRF "token" for the active user session is out of date, even if the token was specified in ajax request.
当活动用户会话的 CSRF“令牌”过期时，您也可能会收到该错误，即使令牌是在 ajax 请求中指定的。
