如何检查nodejs中的标题？

Question

这是运行良好的实际代码，但我想检查我的标头是否很好地传输到我的 api：

var request = require('request');
var express = require('express');
var router = express.Router();

/* GET data by sportId */
router.get('/:locale/:sportId/:federationId/:date', function(req, res) {
    var date = req.params.date;
    var locale = req.params.locale;
    var sportId = req.params.sportId;
    var federationId = req.params.federationId;

   request(getEventsOptions(sportId, federationId, date, locale), function(error, response, body) {
    res.send(body);
   });
});

// get options for request
function getEventsOptions(sportId, federationId, date, locale)
{
    return {
        url: `http://myapi.com/event/sport/${sportId}/date-from/${date}`,
       headers: {
         'accept': 'application/json',
         'dateTo': date,
         'federationIds': federationId,
         'X-Application-ID': 'sporter',
         'Accept-Language': locale,
     }
   };
}

所以我的问题很笼统，我如何在 node js 应用程序中检查我的调用标头？

Answer 1

有三种方法可以做到这一点：

首先，使用 req.get 函数：

req.get('headerName');

二、使用req.header函数：

req.header('headerName');

三、使用req.headers实际对象：

req.headers['headerName'];

我希望它能帮助你。

Answer 2

根据文档，您需要req.get函数。您还可以将 req.headers 对象与所​​有发送的标头一起使用。

代码示例：

const request = require('request');
const express = require('express');
const router = express.Router();

router.get('/:locale/:sportId/:federationId/:date', (req, res) => {
  // destructuring assignment for better readability
  const { date, locale, sportId, federationId } = req.params;

  // header example with get
  const authHeader = req.get('Authorization');
  console.log(authHeader);
  // example with headers object
  console.log(req.headers);


  request(getEventsOptions(sportId, federationId, date, locale), (error, response, body) => {
    res.send(body);
  });
});

function getEventsOptions(sportId, federationId, date, locale) {
  return {
    url: `http://myapi.com/event/sport/${sportId}/date-from/${date}`,
    headers: {
      'accept': 'application/json',
      'dateTo': date,
      'federationIds': federationId,
      'X-Application-ID': 'sporter',
      'Accept-Language': locale,
    }
  };
}
