THINKPHP跨域报错的解决方案

<选修php
 
// 中央件配备
 
use think\middleware\AllowCrossDomain;
 
return [
    AllowCrossDomain::class
];
 

Access to XMLHttpRequest at from origin has been blocked by CORS policy: 
Request header field x-token is not allowed by 
Access-Control-Allow-Headers in preflight response.

<选修php
 
namespace app\middleware;
use think\middleware\AllowCrossDomain;
 
 
class AllowCrossDomainMiddleware extends AllowCrossDomain
{
    // 到场自界说乞求头参数 X-Token
    protected $header = [
        'Access-Control-Allow-Credentials' => 'true',
        'Access-Control-Max-Age'           => 1800,
        'Access-Control-Allow-Methods'     => 'GET, POST, PATCH, PUT, DELETE, OPTIONS',
        'Access-Control-Allow-Headers'     => 'Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-CSRF-TOKEN, X-Requested-With, X-Token',
    ];
}

<必修php
 
// 中央件部署
 
use think\middleware\AllowCrossDomain;
use app\middleware\AllowCrossDomainMiddleware;
 
return [
    // 没有利用默许的跨域中央件
    // AllowCrossDomain::class
 
    // 利用自界说跨域中央件
    AllowCrossDomainMiddleware::class
];
 

// 加添容许跨域乞求头
header("'Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-CSRF-TOKEN, X-Requested-With, X-Token");
header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS, PATCH');
 
// 处置 OPTIONS 恳求
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
    exit;
