如何在nodejs中获取响应头的值

Question

const URL = 'https://www.imdb.com/title/tt0816222/? 
ref_ = fn_al_tt_2 ';

(async() => {

    const response = await request({
      uri: URL,
      headers: {
        'Connection': 'keep-alive',
        'User-Agent': 'Mozilla/0.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36'

      },

    });

I need help from this code. How can I get the response header values in console of visual studio code for the following site.

Answer 1

Just handle the Promise from request library

  request({
    uri: 'https://www.imdb.com/title/tt0816222/?',
    headers: /*your headers*/ 
    })
    .then(function(response){
       console.log(response.headers)
    })

Answer 2

您将在 response.headers 中获得响应标头

Answer 3

像这样打印

console.log(response.headers)

Answer 4

This code prints headers:

const URL = 'https://www.imdb.com/title/tt0816222/?ref_ = fn_al_tt_2';
const request = require('request');

(async () => {

  const response = await request({
    uri: URL,
    headers: {
      'Connection': 'keep-alive',
      'User-Agent': 'Mozilla/0.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36'

    },

  });
  console.log(response.headers);
})();

Answer 5

Because you are just fetching the body of response from request npm.

add resolveWithFullResponse: true in request options.

 const URL = 'https://www.imdb.com/title/tt0816222/? ref_ = fn_al_tt_2 '; (async() => { const response = await request({ uri: URL, headers: { 'Connection': 'keep-alive', 'User-Agent': 'Mozilla/0.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36' }, resolveWithFullResponse: true });

if you need to only headers

 const URL = 'https://www.imdb.com/title/tt0816222/? ref_ = fn_al_tt_2 '; (async() => { const {headers} = await request({ uri: URL, headers: { 'Connection': 'keep-alive', 'User-Agent': 'Mozilla/0.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36' }, resolveWithFullResponse: true }); console.log(headers)
