Question

在我的快递应用中，我想要以下路线。

/regions

/regions/europe

/regions/europe/france

/regions/europe/france/paris

我目前正在使用以下设置但是想知道是否有更简洁的方法？例如，您可以在一台服务器中处理这一切吗？

目前，如果我只有最后一部分/regions/:region/:country/:city并转到/regions/europe/france，我会找不到404页？

server.get('/regions/:region/', (req, res) => {
  const actualPage = '/regions'
  const queryParams = {
    region: req.params.region
  }
  app.render(req, res, actualPage, queryParams)
})

server.get('/regions/:region/:country', (req, res) => {
  const actualPage = '/regions'
  const queryParams = {
    region: req.params.region,
    country: req.params.country
  }
  app.render(req, res, actualPage, queryParams)
})

server.get('/regions/:region/:country/:city', (req, res) => {
  const actualPage = '/regions'
  const queryParams = {
    region: req.params.region,
    country: req.params.country,
    city: req.params.country
  }
  app.render(req, res, actualPage, queryParams)
})

Answer 1

这应该是非常相同的：

const handleRegion = (req, res) => {
  app.render(req, res, '/regions', req.params)
}

server.get('/regions/:region/', handleRegion)
server.get('/regions/:region/:country', handleRegion)
server.get('/regions/:region/:country/:city', handleRegion)

Answer 2

您可以将一系列路由传递给get方法，这是一个示例：

server.get([
    '/regions/:region',
    '/regions/:region/:country',
    '/regions/:region/:country/:city'
], (req, res) => {

    const actualPage = '/regions'

    const queryParams = req.params

    res.render(req, res, actualPage, queryParams)
})

表达处理多级req参数
