Var cookieContainer = BuildCookieContainer(pageCookies) Īwait DownloadFileRequiringHeadersAndCookies(getUrl, fullPath, cookieContainer, cancellationToken) Īwait page.ClickAsync("button") Var pageCookies = await page.GetCookiesAsync() Add the cookies to a container for the upcoming Download GET request If (contentType.Contains("application/vnd.ms-excel")) Handle the response with the Excel download Page.Response += async (sender, responseCreatedEventArgs) => Handle multiple responses and process the Download 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. Puppeteer creates its own browser user profile which it cleans up on every run.I had a more difficult variation of this, using Puppeteer Sharp. This article describes some differences for Linux users. See this article for a description of the differences between Chromium and Chrome. See Puppeteer.launch() for more information. You can also use Puppeteer with Firefox Nightly (experimental support). const puppeteer = require ( 'puppeteer' ) Ĭonst browser = await puppeteer. You create an instance of Browser, open pages, and then manipulate them with Puppeteer's API.Įxample: navigating to and saving a screenshot as example.png: Puppeteer will be familiar to people using other browser testing frameworks. All examples below use async/await which is only supported in Node v7.6.0 or greater. Starting from v3.0.0 Puppeteer starts to rely on Node 10.18.1+. Prior to v1.18.1, Puppeteer required at least Node v6.4.0.
