Haproxy 重定向

Question

我有一个 Haproxy 可以从 https://sede.example.com.br to https://sede.example.pub 重定向。 Haproxy配置不跟随重定向的问题

如果我使用传递 -L 参数的 curl 命令进行测试（跟随重定向），它工作正常

curl -L https://sede.example.com.br

但我需要在没有 -L 选项的情况下工作，因为并且有一个 API 系统可以进行一些 Post 和 Get 操作并且不遵循重定向。所以我需要在 Haproxy 中这样做。

配置：

global
    log /dev/log    local0
    log /dev/log    local1 notice
    chroot /var/lib/haproxy
    stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners
    stats timeout 30s
    user haproxy
    group haproxy
    daemon

        acl sede_acl req.hdr(host) -i -m str sede.example.com.br
        redirect code 301 prefix https://sede.example.pub if sede_acl

我的配置有什么想法吗？

你可以试试下面的代码片段，它未经测试，但我希望你能理解

frontend http-in
    option httplog
    bind *:80
    bind *:443 ssl crt /usr/local/etc/haproxy/haproxy.cfg/certs/
    timeout http-request 60s
    timeout http-keep-alive 4s
    acl https ssl_fc
    http-request set-header         X-Forwarded-Proto http if !https
    http-request set-header         X-Forwarded-Proto https if https

    stats uri /haproxy?examplehaproxystats74581257445
    log-format %{+Q}o\ %{-Q}ci\ -\ -\ [%T]\ %r\ %ST\ %B\ \"\"\ \"\"\ %cp\ %ms\ %ft\ %b\ %s\ \%Tq\ $

    acl sede_acl req.hdr(host) -i -m str sede.example.com.br
    # redirect code 301 prefix https://sede.example.pub if sede_acl
    use_backend sede_acl if sede_acl
  
backend sede_acl
  http-request set-header Host sede.example.pub
  server sede-server sede.example.pub:443 sni sede.example.pub ssl
