如何使用 Node JS 中的請求單擊網站上的按鈕

Question

我想在這個頁面點擊測試產品： https://biscuit-bird.myshopify.com/collections/all

我正在嘗試 go 完全基於請求，而不是使用像 puppeteer 或僵屍這樣的無頭瀏覽器，因為我已經這樣做了。

請通過發送請求讓我知道如何執行此操作。

我假設你正在使用這個庫？ https://github.com/request/request

If so, inside a callback function that provides body of the page, you can use some lib to parse HTML content, find your link to a test product with CSS selector, and then open the URL stored in href .

這個剪斷對我有用：

const request = require('request');
var HTMLParser = require('node-html-parser');


request({
  url:'https://biscuit-bird.myshopify.com/collections/all',
  headers: {
    'User-Agent':'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1'
  }
}, function (error, response, body) {

  // parse method returns a root of the generated DOM
  const root = HTMLParser.parse(body)
  
  // similarly to the browser's DOM, you can lookup DOM elements by their selector using method querySelectorAll  
  const links = root.querySelectorAll("a.grid-link")

  const href = links[0].getAttribute('href');

  // @TODO: send another request to the URL defined in `href`
});
