Note：如果项目打不开,请检查部分依赖包是否已经正确安装,各依赖间版本是否对等匹配

react-router-dom路由

Redirect, Route, Switch,Link,withRouter

不采用nginx在前台项目的packagejson中需设置代理："proxy": "http://localhost:3002"

#开发环境的项目打包后不能使用代理 解决方法：1.开启nginx服务器集群：设置如下：

1. 打开nginx.conf配置文件

所有请求(不与下面匹配的请求(表示任意路由路径))都转发给前台应用 location / { proxy_pass http://localhost:3000; }
所有以/api开头的请求都转发给后台服务器应用 location ~ /api/ { proxy_pass http://localhost:3002; } 当访问nginx服务器时会根据路径跳转到前台或后台

2. 解决方法2：打包好的项目文件直接放在后台public目录下面作为静态文件使用，访问的端口号为后台端口，前后台一致
