一、本地开发必备

1. nginx（本人用的是win nginx-1.16.1版本的） ；
2. 配置nginx:

#user  nobody;
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    client_header_timeout 15;
    client_body_timeout 15;
    send_timeout 25;
	client_max_body_size 500m;
  	add_header Access-Control-Allow-Origin *;
  	add_header Access-Control-Allow-Headers X-Requested-With;
  	add_header Access-Control-Allow-Methods GET,POST,OPTIONS;

	server {
    	listen 80;
    	server_name localhost;
    	root  html;
	
		location /api/ {
			proxy_pass http://你的后台服务ip或者域名:8680/api/;
		}
	
		location ^~ /static-web-1/ {
	  	proxy_pass http://127.0.0.1:8082/static-web-1/;       
		}
		
		location ^~ /static-web-2/ {
	  		proxy_pass http://127.0.0.1:8081/static-web-2/;       
		}

		location ^~ /admin-static-web/ {
			proxy_pass http://127.0.0.1:8080/admin-static-web/;    
		}
		
		#可以用这种方式代理本地的开发，nginx支持vue多项目代理
    	location / {
        	proxy_pass http://127.0.0.1:8080/;       
    	}     						
  	}   
}

4. 配置host（C:\Windows\System32\drivers\etc）

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost
127.0.0.1       ljq.imflea.com

6. 全部web都使用xby.imflea.com这个域名登陆即可 ；

二、图搞懂cookie多网站共享原理

说白了就是统一一个父域名，其他的都在这个域名下代理完成即可。
