配置好以后，链接将会变成 http://url/childFolder/xxx 的形式

1.修改 router/index.js文件 增加mode:’history’,base:’childFolder’

export default new Router({
  mode: 'history',
  base:'childFolder',
  routes: [...]

2.后端也要配置下，这里以nginx为例

找到：location / {...}

另起一行写入：

location /childFolder {
    try_files $uri /childFolder/index.html;
}

附上完整的nginx配置

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;

    #access_log  logs/host.access.log  main;
    root   /usr/local/nginx/html;
    location / {
        index  index.html index.htm;
    }
    location /childFolder {
        try_files $uri /childFolder/index.html;
    }
}
