Php dockerized laravel服务器拒绝POST请求

以下是REST API Laravel服务器的completely reproducible个docker镜像:

FROM php
RUN apt-get update
RUN apt-get install zip -y
COPY --from=composer:latest /usr/bin/composer /usr/local/bin/composer
RUN composer create-project laravel/laravel frontend
WORKDIR frontend
COPY web.php web.php
RUN mv web.php routes
EXPOSE 8000
CMD [ "php", "artisan", "serve", "--host", "0.0.0.0" ]

我唯一编辑的是一个端点(web.php):

<?php

use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return csrf_token();
});

Route::post('/', function (Request $request) {
    if ($request->hasFile('source'    )) { return ">> GOOD ! <<"; }
    if ($request->hasFile('input.json')) { return ">> GOOD ! <<"; }

    $x = count($_FILES);

    return "DD >> $x << DD";
});

我构建并运行docker映像，如下所示:

$ docker build --tag host.translator.php --file Dockerfile .
$ docker run -p 8008:8000 -d -t --name translator.php host.translator.php

然后就像相关文章说的(here，and here，and also here):

$ Set-Variable -Name X -Value (curl.exe -X GET -F "source=@input.json" http://127.0.0.1:8008/)
# X holds the token:
# echo $X
# U263lUv3dz9PH7ySm3GmgUUjHjjWm78cqofODUmh

但当我try 使用该令牌时，它不起作用:

$ curl.exe --header "X-CSRFToken:$X" -X POST -F "source=@input.json" http://127.0.0.1:8008/ | Select-String "<title>Page Expired"
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  6851    0  6609  100   242  80486   2947 --:--:-- --:--:-- --:--:-- 83548

        <title>Page Expired</title>

如有任何帮助，我们将不胜感激，谢谢！
