我是express的新手。我有一个运行在express上的Vue应用程序。我有一些API路由，我可以通过浏览器使用axios访问。为了使用postman访问这些路由，我必须要有以下头部：
accept: application/javascript
为了让API返回实际结果，我需要使用这个头部信息。如果不使用这个头部信息，我会从webpack得到生成的index.html。我需要重复使用其中一个路由来返回基于参数的Excel/PDF，并通过页面上的链接进行访问。
这是我的server.js - 基于https://github.com/southerncross/vue-express-dev-boilerplate

export default app以下是 api.js 的一小部分代码：
const {Router} = require ('express')
const router = Router()
router.get('/whome', function(req, res){
logger.info('whome', req.user)
return res.json(req.user)
})
router.get ('/hello', auth.isAuthenticated, async (req, res) => {
res.json ({text:'hello'})
})
module.exports = router我可以在Postman中使用accept:application/javascript标头调用http://localhost/api/hello，然后得到以下结果：
{
"text": "hello"
}
预料之中。但是如果我从浏览器调用同样的URL（且没有发送该标头），我会得到创建的捆绑索引文件index.html。如何从浏览器访问这些路由？
