Nginx proxy_redirect 与相对路径

Nginx proxy_redirect 与相对路径

我不是 nginx 管理方面的专家,我只是一名开发人员。我有两个后端在 docker 中运行。让我给它们命名

  • 后端1:8080
  • 后端2:8081

另外,我安装了 letsencrypt 证书,并公开了 443 端口的 Nginx。我的 Nginx 配置是(环境变量 FQDN 类似于 example.com)

upstream backend1 {
  server backend1:8080;
}

upstream backend2 {
  server backend2:8081;
}

server {
  listen 443 ssl;
  
  server_name ${FQDN} www.${FQDN};
  
  ssl_certificate /etc/letsencrypt/live/${FQDN}/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/${FQDN}/privkey.pem;
  ssl_session_cache shared:SSL:1m;
  ssl_session_timeout  5m;
  ssl_ciphers  HIGH:!aNULL:!MD5;
  ssl_prefer_server_ciphers   on;

  if ($server_port = 80) { set $https_redirect 1; }
  if ($host ~ '^www\.') { set $https_redirect 1; }
  if ($https_redirect = 1) { return 301 https://${FQDN}$request_uri; }
  
  location /path1/ {
    
    proxy_pass http://backend1/;

    proxy_redirect ~^/(.*) $scheme://$http_host/path1/$1;
    
    proxy_http_version 1.1;
    
    proxy_pass_header Set-Cookie;
    proxy_pass_header Cookie;
    proxy_pass_header X-Forwarded-For;

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forward-Proto http;
    proxy_set_header X-Nginx-Proxy true;
    add_header       X-Upstream      $upstream_addr;
  }
  
  location /path2/ {
    
    proxy_pass http://backend2/;

    proxy_redirect ~^/(.*) $scheme://$http_host/path2/$1;
    
    proxy_http_version 1.1;
    
    proxy_pass_header Set-Cookie;
    proxy_pass_header Cookie;
    proxy_pass_header X-Forwarded-For;

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forward-Proto http;
    proxy_set_header X-Nginx-Proxy true;
    add_header       X-Upstream      $upstream_addr;
  }
}

我希望如果我发出请求https://exapmle.com/path1/,Nginx 应该转到http://backend1:8080/该服务器并返回响应。问题是 backend1(以及 backend2)可以响应 302 并重定向到某个路径,例如。Nginx/login将我的浏览器重定向到,https://exapmle.com/login但我希望它将我重定向到https://exapmle.com/path1/login 您能否帮助我并指出我在配置中犯的错误。我已经查看了 SO 中所有类似的问题,但没有找到任何解决方案。我还浏览了 Nginx 文档,但也没有找到答案。

我有这条线路proxy_redirect ~^/(.*) $scheme://$http_host/path1/$1;,我想它一定能完成我想要的工作。

顺便说一句,我无法在 Nginx 配置中占用 / 位置(为根路径创建配置),因为它已保留给另一个后端服务器。提前致谢。

答案1

可能是因为您的配置中的 X-Forwarded-Headers 拼写错误。它应该是X-Forwarded-*而不是X-Forward-*

答案2

location /path1/ {

proxy_pass http://backend1/;

proxy_redirect default;
proxy_redirect / /path1/;
proxy_redirect  http://backend1/ https://exapmle.com/path1/;

proxy_http_version 1.1;

proxy_pass_header Set-Cookie;
proxy_pass_header Cookie;
proxy_pass_header X-Forwarded-For;

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forward-Proto http;
proxy_set_header X-Nginx-Proxy true;
add_header       X-Upstream      $upstream_addr;}

那没问题;
