javascript - 初学angularJS+express，路由路径中/转换成%2F，导致路径失效，求原因？
页面打开如下
点击电脑链接，显示url路径如下
点击后
期望的效果如下：
我的代码如下 app.js，用的是"express": "^4.15.2"
var express = require('express');
var path = require('path');
var app = express();
//使用静态文件服务器中间件
app.use(express.static(path.join(__dirname,'app/public')));
app.listen(8080);test.html
<html ng-app="routingDemoApp">
<head>
<meta charset="utf-8">
