我的目標是擁有一個可以 proxy_pass 到其他伺服器的 nginx。
Desired input
https://example.com/https://assets1.com/image.jpg?utm=whatever
Desired output
https://assets1.com/image.jpg?utm=whatever
這是我的位置區塊
server {
index index.html index.htm index.nginx-debian.html;
server_name example.com www.example.com;
location ~/(.*) {
if ($request_method = 'GET') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User->
}
proxy_pass https://$1$is_args$args/;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host "www.example.com";
}
listen 80;
listen [::]:442 ssl ipv6only=on;
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
我得到的錯誤是:
2021/09/21 09:27:32 [錯誤] 8475#8475: *16上游連接埠無效 “https://assets1.com/image.jpg?utm=whatever”,客戶端:[IP],伺服器:domain.com,請求:“GET /https://assets1.com/image.jpg?utm= whatever HTTP /1.1”,主機:“example.com”
答案1
您的原始請求 URL 包含協定前綴:https://example.com/https://assets1.com
。
你的location
塊捕獲了第一個之後的部分/
,所以$1
變成了https://assets1.com
。
在你的proxy_pass
語句中,你有,當變數擴展時https://$1$is_args$args
它就會變成。https://https://assets1.com
nginx 嘗試解析https://assets1.com
為網域:連接埠對,因此 URL 的網域部分是https
,連接埠是空字串。
為了解決這個問題,我建議如下配置:
location ~^/https://(.+)$ {
proxy_pass https://$1$is_args$args;
...
}
這樣我們就可以排除協定部分被捕獲到 $1 中,這樣我們就有了一個正確的 URL。我還添加了開始和結束錨點以使正則表達式更加健壯。
