问题

在部署完项目后 刷新页面，页面进入了404

分析

• 加载单页应用后路由改变均由浏览器处理，而刷新时将会请求当前的链接，而Nginx无法找到对应的页面
  关键代码try_files,剩下俩如果其他地方配置了则可以省略。
  在这里解释一下try_files的意思，顾名思义try files 尝试获取文件。
  如果一个地址是localhost:8899/login
  那么uri指的是login地址,uri/指的是login文件夹

解决

添加一行代码：

   location / {
        root /www/wwwroot/phm/phmweb;
        index  index.html index.htm;
        try_files  $uri $uri/ /index.html;
    }

这段代码的意思是，如果访问一个地址首先会尝试读取第一个地址的页面文件，第一个地址无法访问的话会访问同名文件夹，如果文件夹也不存在那么就返回默认的index.html文件，这样配置好之后再刷新就能正常显示了

附上我的 nginx.conf 文件
