登录依赖cookie，且cookie是跨域不共享的，如果是前后台分离开发，肯定存在跨域的情况，有时需要在服务器上同时启动前后台服务，然后使用nginx服务器配置反向代理来解决前后台跨域问题
参考：https://www.runoob.com/linux/nginx-install-setup.html
步骤
- 下载：https://nginx.org/en/download.html （下载速度很快，压缩包）
- 解压到指定位置，比如C盘根目录，并重命名为nginx
- 使用vscode打开 windows:C:\nginx\conf\nginx.conf
- 参数：
worker_processes 1; （cpu是几核的，负载均衡）
listen 9090; （监听端口）
proxy_pass http://localhost:9001; （前台服务端口）
proxy_pass http://localhost:9000; （后台服务端口） - 可以做多服务跨域处理
#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;
}

# HTTPS server

# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {

# index index.html index.htm;
# }

}
- 保存测试
用vscode或者win+R cmd 打开windows:C:\nginx
输入：start nginx
然后：nginx -t 检测是否成功启动，出现以下字样，代表nginx启动成功
nginx: the configuration file C:\nginx/conf/nginx.conf syntax is ok
nginx: configuration file C:\nginx/conf/nginx.conf test is successful - 跨域测试
浏览器输入：http://localhost:9090/index.html （此端口是监听端口，非前后端服务端口）
打开页面后，前端服务可以正常访问接口，证明nginx跨域代理成功 - nginx 常用命令
启动：start nginx 或者 nginx
重启：nginx -s reload
停止：nginx -s stop
检测是否成功：nginx -t
