ruby-on-rails-使用Nginx Gzip Unicorn时缺少Content-Length标头

我不知道为什么在nginx中使用gzip时会错过http响应“ Content-Length header”,我真的被卡住了,请有人帮帮我,非常感谢！
这是我的配置文件,

nginx.conf

用户无人无人;
worker_processes 8;

events {
    worker_connections  1024;
    accept_mutex on; # "on" if nginx worker_processes > 1
    use epoll; # enable for Linux 2.6+
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    upstream backend-unicorn {
        server unix:/tmp/unicorn_app.sock fail_timeout=0;
        #server localhost:5000;
    }
    #access_log  logs/access.log  main;
    sendfile        on;
    keepalive_timeout  100;
    gzip on;
    gzip_static on;
    gzip_proxied any;
    gzip_http_version 1.1;
    gzip_comp_level 6;
    gzip_min_length  1100;
    gzip_buffers 16 8k;
    gzip_types text/plain application/zip text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript image$

    server {
        listen       8080;
        server_name  misago;
        access_log  /var/log/nginx/unicorn.access.log  main;
        client_max_body_size 64M;
        location /uploads/ {
            root /usr/local/rails_apps/me_management_tool/current/public/uploads;
            break;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }

}

I don’t know why http response is missed “Content-Length header” when I use gzip in nginx

因为在这种情况下,发送标头时内容的长度是未知的. Nginx无法知道内容压缩的程度.
