await using (var browser = await Puppeteer.LaunchAsync(new LaunchOptions ))Īwait using (var page = await browser.NewPageAsync()) Once I had that particular response, I had to attach headers and cookies for the remote server to send the downloadable data in the response. In essence, before the button click, I had to process multiple responses and handle a single response with the download.
I needed both Headers and Cookies set before the download would start. child.jsĬonsole.log("CHILD: url received from parent process", url) Īwait page._nd('Page.I had a more difficult variation of this, using Puppeteer Sharp. For every URL a replacement child thread is going to be initiated. During this file we initiate our child processes and send the URL of the pictures we would like to download. We have two files during this solution, the primary one is main.js. const puppeteer = require('puppeteer') Ĭonst downloadPath = path.resolve('./download') Īwait page._nd('tDownloadBehavior', `) Let’s update our script to line the trail. We can avoid the default download path by explicitly specifying the trail in our script. Finally, we are using the click() function to simulate the button click. Then we are opening up a replacement tab with the given URL. We are creating a replacement instance of Puppeteer. This may allow us to watch the automation in real-time. The headless option is about to be false. We can use the subsequent script to automate the download process Finally, we’ll click on the download button. Then we’ll find the download button on the page. we’ll open up a URL during a new browser tab. In the first example, we’ll take a glance at an easy scenario where we automate a button click to download a picture. Downloading a picture by simulating button click We’ll undergo several practical examples and take a deep dive into Puppeteer’s APIs used for file download. That’s why this text is there to share a number of the ideas and tricks which will be used while working with Puppeteer. Unfortunately, these use cases aren’t well documented. You perhaps have to explicitly specify a download location, download multiple files at an equivalent time, and so on. In this article, we’ll discuss the way to efficiently download files with Puppeteer.
