在 nginx 中添加和使用标头(HTTP) [英] Adding and using header (HTTP) in nginx

问题描述

我使用了两个系统(两个都是 Nginx 负载均衡器，一个用作备份).

I am using two system (both are Nginx load balancer and one act as backup).

我想添加和使用一些 HTTP 自定义标头.

I want to add and use few HTTP custom headers.

以下是我的代码；

upstream upstream0 {
    #list of upstream servers
    server backend:80;
    server backup_load_balancer:777 backup;
    #healthcheck
}

server {
    listen 80;
    #Add custom header about the port and protocol  (http or https)
    server_name _;

    location / {
        # is included since links are not allowed in the post
        proxy_pass "http://upstream0;"
    }
}

备份系统

server {
    listen 777;
    server_name _;
    #doing some other extra stuff
    #use port and protocol to direct
}

我怎样才能做到这一点?

How can I achieve that?

推荐答案

要添加标题，只需将以下代码添加到要添加标题的位置块:

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

显然，将 x-my-header 和 my-header-content 替换为您要添加的内容.仅此而已.

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.
