這是我正在建立的伺服器系統。
- 原始網站.com
- 重複網站.com
- 不允許的重複網站.com
我將一些內容放在original-website.com 中。

This book is written by Zeal Vora. It's a good book. I am just writing filler content here.

現在，我造訪duplicate-website.com 和unallowed-duplicate-website.com 並複製其中的內容，並將圖片引用到original-website.com。

相同的內容被貼到unallowed-duplicate-website.com
現在，我將 IP 與網域映射新增至每個主機檔案。像這樣：
192.168.1.75 duplicate-website.com
192.168.1.76 original-website.com
192.168.1.74 unallowed-duplicate-website.com
然後，我去/etc/nginx/conf.d/original-website.conf
#original-website.conf
server{
listen 80;
server_name original-website.com;
location / {
root /usr/share/nginx/html/;
location ~* \.(jpg|png|gif|jfif)$ {
valid_referers none duplicate-website.com;
if ($invalid_referer) {
return 403;
}
}
}
}
現在，當我進入瀏覽器並輸入重複網站的 IP 位址時，我看不到該圖像。為什麼？
