Nginx 代理 - proxy_set_header - 来自 site.conf 的自定义 header(对于清漆缓存)

Nginx proxy - proxy_set_header - custom header from site.conf (For Varnish Cache)

是否可以在您的网站中发送 自定义 header,然后使用 proxy_set_header 将其转发到 Varnish?

信息

我稍微移动了文件夹位置 - 所有内容都正确包含并且可以使用。

我有 /etc/nginx/conf.d/params/proxy.params/proxy_params 个文件:

proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Port-Nginx $server_port;
proxy_set_header X-Forwarded-DocumentRoot $document_root;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Ssl-Offloaded $scheme;
proxy_set_header X-Forwarded-Custom-Location-Site 'Custom Site';   ### THIS IS THE HEADER I WANT TO BE DYNAMIC
fastcgi_param  HTTPS on;

然后在我的 https 服务器块中 sites-enabled/custom-site.conf:

server {
    listen 443 ssl default_server;
    server_tokens off;
    add_header 'Access-Control-Allow-Origin' '*';
    add_header 'Custom-Location-Site' 'mysite1';
    root /var/www/html;
    server_name nginx-glo 192.168.1.105 localhost:443;

    location / {
        access_log /var/log/nginx/access.log main;
        add_header 'Custom-Nginx-Server-Location-Root-Redirect' 'From /';   #### This header does not appear in varnishlog  (testing only)
        include /etc/nginx/conf.d/params/proxy.params/proxy_params_destination.conf;

相关proxy_params_destination.conf

server_tokens off;

proxy_redirect off;
include /etc/nginx/conf.d/params/proxy.params/proxy_params;
# Try not to add headers using add_header, this will reset all headers from other locations
# that are redirected here.
# Also do not log to file here, log in locations above.

proxy_headers_hash_bucket_size 356;
proxy_read_timeout 3600;
proxy_connect_timeout 60;
# Cannot use https:// for proxy calls - use http, outside connection is https
proxy_pass http://varnish-cache-magento2.3.5:6081;
#proxy_pass http://web-server-apache2-magento2.3.5:8080;

我想做的事情:

原因:

Varnish cache setup for multiple Magento 2 sites.

Link to sample multiple backends

示例中的相关部分:

sub vcl_recv {
    if (req.url ~ "^/java/") {
        set req.backend_hint = java;
    } else {
        set req.backend_hint = default;
    }
}

backend default {
    .host = "127.0.0.1";
    .port = "8080";
}
Now let’s add a new backend:

backend java {
    .host = "127.0.0.1";
    .port = "8000";
}

清漆日志

如此处所示:varnishlog 已经在 Docker 容器中收到我的自定义 header。我现在需要自定义 header 的值是动态的。

-   ReqHeader      X-Real-IP: 192.168.1.103
-   ReqHeader      X-Forwarded-For: 192.168.1.103
-   ReqHeader      X-Forwarded-Port-Nginx: 443
-   ReqHeader      X-Forwarded-DocumentRoot: /var/www/html
-   ReqHeader      X-Forwarded-Proto: https
-   ReqHeader      Ssl-Offloaded: https
-   ReqHeader      X-Forwarded-Custom-Location-Site: Custom Site

如果我没理解错的话,这就是你需要的:

proxy_set_header X-Forwarded-Custom-Location-Site $http_custom_location_site;

这使得 X-Forwarded-Custom-Location-site 动态,基于您配置 Custom-Location-Site header.

server

例如,如果 Custom-Location-Site 的值为 mysite1,则 X-Forwarded-Custom-Location-site 的值将如下所示:

X-Forwarded-Custom-Location-site: mysite1

根据 http://nginx.org/en/docs/http/ngx_http_core_module.html#var_http_,您可以将 $http_ 与任何 header 一起使用。您只需将值小写,并将破折号替换为下划线。
