javascript - 从服务器中的搜索栏访问值？

我想从server.js页面的html页面的搜索表单中获取用户输入的值，但不知道如何输入。我知道名称/值对将是cityCode = something，但不知道从那里开始做什么？

HTML：

      <form class="form-inline my-2 my-lg-0" id="form" action="/hotels" method="GET">
        <!-- location search bar -->
        <input
          class="form-control mr-sm-2"
          type="text"
          placeholder="Search Location"
          aria-label="Search"
          id="searchbar"
          name="cityCode"
        >
        <!-- end of location search bar-->

        <!-- start of location search button -->
        <button class="btn btn-outline-success my-2 my-sm-0" type="submit" id="searchbutton">
          Search
        </button>
        <!-- end of location search button-->
      </form>

server.js：

var express = require('express');
var app = express();
app.use(express.static('public'));
var Amadeus = require('amadeus');

app.set('view engine', 'ejs');
app.listen(8080);

app.get('/hotels', function(req, res){
    amadeus.shopping.hotelOffers.get({
    //'PAR' to be replaced by user input
        cityCode: 'PAR'
    }).then(function(response){
    var jsonData = JSON.parse(response.body);

    res.render('pages/onestar', {jsonData: JSON.stringify(jsonData.data[1].type)});

    }).catch(function(error){
      console.log(error.response); //=> The response object with (un)parsed data
      //console.log(error.response.request); //=> The details of the request made
      console.log(error.code); //=> A unique error code to identify the type of error
    });
});

最佳答案

由于您的表单使用的是方法GET，因此您的提交将发送cityCode作为查询参数。要在Express中访问它，请使用req.query：

app.get('/hotels', async function(req, res, next) {
  try {
    const response = await amadeus.shopping.hotelOffers.get({
      cityCode: req.query.cityCode
    });
    const jsonData = JSON.parse(response.body);
    res.render('pages/onestar', {jsonData: JSON.stringify(jsonData.data[1].type)});
  } catch (error) {
    console.log(error.response); //=> The response object with (un)parsed data
    //console.log(error.response.request); //=> The details of the request made
    console.log(error.code); //=> A unique error code to identify the type of error
    next(error);
  }
});
