Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. Var cookieContainer = new CookieContainer() ĬookieContainer.Add(new Cookie(cookie.Name, cookie.Value, cookie.Path, cookie.Domain)) Populate the Cookie Container like this: private CookieContainer BuildCookieContainer(IEnumerable cookies) NEED THIS TIMEOUT TO KEEP THE BROWSER OPEN WHILE THE FILE IS DOWNLOADING!Īwait page.WaitForTimeoutAsync(1000 * configs.DownloadDurationEstimateInSeconds) 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 We’ll go from CLIs to scrapping tools, among others. This blog post is part of a a blog post series where we use Deno to build different applications. If (contentType.Contains("application/vnd.ms-excel")) learning as we go Using Puppeteer with Deno. 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.
