nginx配置

  location / {
        root /usr/share/nginx/html;
        index  index.html index.htm;
        try_files $uri $uri/ /groupMobile/index.html;  //一定要写上项目的基础路径。除非直接是没有项目基础路径的，把项目里面的文件都直接放到html下的
    }

nginx存放项目的路径 groupMobile是的uniapp项目
/usr/share/nginx/html/groupMobile

nginx的try_files+manifest.json h5.router.mode等于history 就可以解决刷新404
