php - Laravel 请求总是在没有引用者的情况下返回

Question

laravel 7.19.1 php 7.4 nginx 1.17.10(ubuntu)

我试图从 request() 或 $_SERVER 获取 HTTP_REFERER 总是在没有引用者的情况下返回

转储请求（）->标头：

Symfony\Component\HttpFoundation\HeaderBag {#49 ▼

#headers: array:12 [▼
   "cookie" => array:1 [▶]
   "accept-language" => array:1 [▶]
   "accept-encoding" => array:1 [▶]
   "accept" => array:1 [▶]
   "user-agent" => array:1 [▶]
   "upgrade-insecure-requests" => array:1 [▶]
   "dnt" => array:1 [▶]
   "cache-control" => array:1 [▶]
   "connection" => array:1 [▶]
   "host" => array:1 [▶]
   "content-length" => array:1 [▶]
   "content-type" => array:1 [▶]
 ]
 #cacheControl: array:1 [▶]
}

转储 $_SERVER：

"USER" => "www-data"
  "HOME" => "/var/www"
  "HTTP_COOKIE" => "XSRF-TOKEN=eyJpdiI6IjBSMHk0ak8zUHNCVGIrRHpncXQxMlE9PSIsInZhbHVlIjoiWXQxUWRFWjFqQ0QyY05OVHhUOWVMcVFIdmdtNUNSK0liZFdRVVZXOTE1aUhhbGkvMDQxU1d6cjR0S3RzQ1hzbyIsIm1hY ▶"

  "HTTP_UPGRADE_INSECURE_REQUESTS" => "1"
