* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

587d7fb0367417b2b2512bee 啓動一個 Express 服務 2 301519 start-a-working-express-server

--description--

myApp.js 文件的前兩行中,你可以看到創建一個 Express 應用對象很簡單。 這個對象有幾種方法,在後面的挑戰中將學習到其中的許多部分。 一個基礎的方法是 app.listen(port)。 它處於運行狀態時告訴服務器監聽指定的端口。 出於測試的原因,需要應用在後臺運行,所以在 server.js 中已經添加了這個方法。

讓我們在服務端輸出第一個字符串! 在 Express 中,路由採用這種結構:app.METHOD(PATH, HANDLER) METHOD 是 http 請求方法的小寫形式, PATH 是服務器上的相對路徑(它可以是一個字符串,甚至可以是正則表達式), HANDLER 是匹配路由時 Express 調用的函數, 處理函數採用這種形式:function(req, res) {...},其中 req 是請求對象res 是響應對象, 例如:

function(req, res) {
  res.send('Response String');
}

將會響應一個字符串“Response String”。

--instructions--

當 GET 請求 /(根路由 )時,使用 app.get() 方法響應一個“Hello Express”字符串。 通過查看日誌確保代碼正常運行,如果使用 Replit 可以在預覽中查看結果。

注意: 這些課程的所有代碼應該放在開始給出的幾行代碼之間。

--hints--

應用應該返回字符串“Hello Express”

(getUserInput) =>
  $.get(getUserInput('url')).then(
    (data) => {
      assert.equal(
        data,
        'Hello Express',
        'Your app does not serve the text "Hello Express"'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
