博客围绕nginx前后端分离使用场景展开，重点提及解决nginx proxy_pass反向代理时cookie、session丢失的问题。指出host、端口转换时cookie不会丢失，路径变化需设置路径转换，防止session丢失可在配置文件最后添加特定语句。

我在工作中主要用到的nginx功能就是前后端分离


#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


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"';

    #access_log  logs/access.log  main;
	

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
	
    server {
        listen       80 default_server;
        #listen       [::]:80 default_server;
        server_name  _;
        root         /usr/local/nginx/html;

        # Load configuration files for the default server block.
        include /usr/local/nginx/conf/default.d/*.conf;

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
    include vhost/*.conf;

}

http {
    
    server
	{
			listen 907;
			server_name localhost;

			root C:\Users\Administrator\Desktop\ccps_7_H-ui.admin.page_3.0;

			#error_page   404   /404.html;

			#access_log /data/logs/project/wallet-mobile-error.log main;

			location ~* \.(html|htm)$
			{
					add_header Cache-Control no-store;
			}


			location ~* \.(html|gif|jpg|png|ico|js|css|otf|eot|svg|ttf|woff|swf|xlsx)$
			{
					root C:\Users\Administrator\Desktop\ccps_7_H-ui.admin.page_3.0;
			}

			location = /
			{
					root C:\Users\Administrator\Desktop\ccps_7_H-ui.admin.page_3.0;
			}
			

			location /
			{
					proxy_pass http://127.0.0.1:8080/blogs/;
			}
	}
}

这是一个最简单的nginx前后端分离的使用场景。

注意点：

1.解决nginx proxy_pass反向代理cookie,session丢失的问题

host、端口转换，cookie不会丢失

location /project {
        proxy_pass   http://127.0.0.1:8080/project;
    }

路径也变化，则需要设置cookie的路径转换

location /proxy_path {
        proxy_pass   http://127.0.0.1:8080/project;
        proxy_cookie_path  /project /proxy_path;
    }

直接代理本地端口

location /proxy_path {
        proxy_pass   http://127.0.0.1:8080/;
        proxy_cookie_path  /project /proxy_path; # project 为你的项目名 也可用变量代替
    }

所以以上面的例子来说，为防止session丢失，那么只需要在配置文件的最后面加一句即可。

proxy_cookie_path /blogs/ /;
