Description

构建API时，我们必须允许用户与我们沟通他们希望从我们的服务中获得什么。例如，如果客户端请求有关存储在数据库中的用户的信息，他们需要一种方法让我们知道他们感兴趣的用户。实现此结果的一种可能方法是使用路由参数。路由参数是URL的命名段，由斜杠（/）分隔。每个段捕获URL的与其位置匹配的部分的值。捕获的值可以在req.params对象中找到。

route_path: '/user/:userId/book/:bookId'
actual_request_URL: '/user/546/book/6754'
req.params: {userId: '546', bookId: '6754'}

Instructions

构建一个安装在路径GET /:word/echo的回显服务器。使用结构{echo: word}响应JSON对象。您可以在req.params.word找到要重复的req.params.word 。您可以从浏览器的地址栏测试您的路线，访问一些匹配的路线，例如 your-app-rootpath/freecodecamp/echo

Tests

tests:
  - text: '测试1：您的echo服务器应该正确重复单词'
    testString: 'getUserInput => $.get(getUserInput(''url'') + ''/eChOtEsT/echo'').then(data => { assert.equal(data.echo, ''eChOtEsT'', ''Test 1: the echo server is not working as expected'') }, xhr => { throw new Error(xhr.responseText); })'
  - text: '测试2：您的echo服务器应该正确重复单词'
    testString: 'getUserInput => $.get(getUserInput(''url'') + ''/ech0-t3st/echo'').then(data => { assert.equal(data.echo, ''ech0-t3st'', ''Test 2: the echo server is not working as expected'') }, xhr => { throw new Error(xhr.responseText); })'
