node.js - 同一域名下不同端口cookie共享问题

Answer 1

Now that the front and back ends are separated, the stateless model should be accepted. Try other ways to solve the state saving problem.

For example: User information can be returned in the login interface and processed by the front end.

Answer 2

Use nginx as a reverse proxy and map services on different ports to a unified port to achieve cookie sharing

nginx configuration file example:

server {
    listen       8080;
    server_name  example.com;

    # 将/api路径映射到3000端口
    location ~ ^/(api)/ {
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }
    
    # 静态资源直接由nginx负责
    location / {
        root       /some/path;
        index      index.html index.htm;
    }
}

After

, access http://example.com:8080/ as a static resource and http://example.com:8080/api/* as an interface
