从 nginx 代理服务器转发请求标头 [英] Forward request headers from nginx proxy server

问题描述

我使用 Nginx 作为代理来过滤对我的应用程序的请求.在http_geoip_module"的帮助下，我正在创建一个国家代码 http-header，我想使用headers-more-nginx-module"将它作为请求标头传递.这是 Nginx 配置中的 location 块:

I'm using Nginx as a proxy to filter requests to my application. With the help of the "http_geoip_module" I'm creating a country code http-header, and I want to pass it as a request header using "headers-more-nginx-module". This is the location block in the Nginx configuration:

location / {
    proxy_pass                      http://mysite.com;
    proxy_set_header                Host http://mysite.com;;
    proxy_pass_request_headers      on;
    more_set_headers 'HTTP_Country-Code: $geoip_country_code';
}

但这只会在响应中设置标题.我尝试使用more_set_input_headers"而不是more_set_headers"，但是标题甚至没有传递给响应.

But this only sets the header in the response. I tried using "more_set_input_headers" instead of "more_set_headers" but then the header isn't even passed to the response.

我在这里错过了什么?

推荐答案

如果要将变量传递给代理后端，则必须使用代理模块进行设置.

If you want to pass the variable to your proxy backend, you have to set it with the proxy module.

location / {
    proxy_pass                      http://example.com;
    proxy_set_header                Host example.com;
    proxy_set_header                HTTP_Country-Code $geoip_country_code;
    proxy_pass_request_headers      on;
}

现在它被传递到代理后端.

And now it's passed to the proxy backend.
