Question

我第一次尝试设置nginx。我有以下问题我想解决。

我有两个版本的后端v1和v2。

用户被路由到“/ v2”（proxy_pass'127.0.0.1：3000;'）

Traffic tru“/”（javascript +套接字）已路由到同一服务器'127.0.0.1:3000;'通过查看cookie。

继承我的问题，cookie不存在，因此将返回404

有什么建议吗？

map $cookie_version $site_version {
    default     "";
    "v1"  "version=v1;Domain=localhost;Path=/";
    "v2"  "version=v2;Domain=localhost;Path=/";
}

server {    
  listen 8081;
  server_name localhost;

location / {
    if ($cookie_version ~* "v1") {
        proxy_pass http://127.0.0.1:8080;
    }       
    if ($cookie_version ~* "v2") {
        proxy_pass http://127.0.0.1:3000;
    }   
}

location /v1 {
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;
    proxy_http_version 1.1;

    set $cookie_version "v1";
    add_header Set-Cookie $site_version;

    rewrite ^/v1(.*) /$1 break;

    proxy_pass http://127.0.0.1:8080;
}
location /v2 {
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;
    proxy_http_version 1.1;

    set $cookie_version "v2";
    add_header Set-Cookie $site_version;

    rewrite ^/v2(.*) /$1 break;

    proxy_pass http://127.0.0.1:3000;
 }
}

首先，阅读为什么如果是邪恶http://wiki.nginx.org/IfIsEvil。请改用map。我的建议是：

map $cookie_version $mybackend {
  default "127.0.0.1:3000";
  "v1" "127.0.0.1:8080";
  "v2" "127.0.0.1:3000";
}
...
location / {
  proxy_pass http://$mybackend;
}
...
location ~ ^/(?<cver>v[12])/ {
  ...
  add_header Set-Cookie "version=$cver;Domain=localhost;Path=/";
  rewrite ^/v[12]/(.*)$ /$1 redirect;
}

使用Cookie Nginx路由流量
