Nginx获取自定义头部header的值
Nginx读取自定义header在参考了资料:
http://stackoverflow.com/questions/8393772/how-to-get-non-standard-http-headers-on-nginx
http://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers
http://serverfault.com/questions/297225/nginx-passing-back-custom-header
https://easyengine.io/tutorials/nginx/forwarding-visitors-real-ip/
http://www.ttlsa.com/nginx/nginx-proxy_set_header/
后得到如下:
1、nginx是支持读取非nginx标准的用户自定义header的,但是需要在http或者server下开启header的下划线支持:
[*] underscores_in_headers on;
2、比如我们自定义header为X-Real-IP,通过第二个nginx获取该header时需要这样:
[*] $http_x_real_ip; (一律采用小写,而且前面多了个http_)
3、如果需要把自定义header传递到下一个nginx:
[*] 如果是在nginx中自定义采用proxy_set_header X_CUSTOM_HEADER $http_host;
[*] 如果是在用户请求时自定义的header,例如curl –head -H “X_CUSTOM_HEADER: foo” http://domain.com/api/test,则需要通过proxy_pass_header X_CUSTOM_HEADER来传递
示例:
http{ upstream myServer {
server 127.0.0.1:8082;
}
underscores_in_headers on;
server {
listen 80;
server_namelocalhost;
location/ {
proxy_set_header Some-Thing $http_x_custom_header;;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://myServer;
}
} }
