使用laravel身份验证时，如何检查用户是否已在“反应”组件中“登录”？
[英]How do I check if user is 'logged in' in a react component when using laravel authentication?
问题描述
I have setup laravel authentication in my website. 
我在我的网站上设置了laravel身份验证。 It works very well but I want to know how I can check if a user is logged in when inside a react component and display his/her specific content. 它工作得很好，但我想知道如何检查用户是否在反应组件内部登录并显示他/她的特定内容。

One approach I have used to solve the problem with checking if the user is logged in is to attach it in your main blade file as 'global data'. 我用来检查用户是否已登录的问题的一种方法是将其作为“全局数据”附加到主刀片文件中。 First set up your controller. 首先设置你的控制器。
public function index()
{
return view('welcome')->with(["globalData" => collect([
'user' => Auth::user()
]);
}
Then in your root blade file 然后在您的根刀片文件中
<script>
let globalData = "{!! $globalData->toJson() !!}";
</script>
Then you can access a user property anywhere in your components by refering to globalData.user and thus test if user is an object or null/empty. 然后，您可以通过globalData.user来访问组件中任何位置的用户属性，从而测试user是对象还是null / empty。
Example from a React project with version 15.4.2 来自版本为15.4.2的React项目的示例
Controller 调节器
class GuiController extends Controller
{
public function __construct() {
$this->data = [
'projects' => $this->projects(),
'packs' => Pack::all(),
'stimpack_io_token' => env('STIMPACK_IO_TOKEN'),
'stimpack_data_url' => env('STIMPACK_DATA_URL'),
'manipulatorData' => ManipulatorController::attachStartupData()
];
}
public function index()
{
return view('welcome')->with(["data" => collect($this->data)]);
}
View 视图
<body>
<div id="main"></div>
<script>
let data = {!! $data->toJson() !!};
</script>
<script src="{{asset('js/app.js')}}" ></script>
</body>
Usage inside component 组件内部的用法
upload() {
var compiler = new Compiler(this.props.engine);
var compiled = compiler.compile();
$.ajax({
type: "POST",
beforeSend: function(request) {
request.setRequestHeader("stimpack-io-token", data.stimpack_io_token);
},
