If your needs to download a file are more simplistic, you can probably use the other methods mentioned on this thread, or the linked thread. The details of DownloadFileRequiringHeadersAndCookies are here. 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() The following workspace dependencies were updated dependencies puppeteer-core bumped from 20.1.0 to 20.1.1 puppeteer/browsers bumped from 1.0.0 to 1.0. Add the cookies to a container for the upcoming Download GET request rename PUPPETEERDOWNLOADHOST to PUPPETEERDOWNLOADBASEURL Dependencies. 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. We then navigate to that URL using the page.goto() function.I had a more difficult variation of this, using Puppeteer Sharp. We then get the url of the page we want to download the image from the user and stored it in a variable named baseURL. We can now heedlessly control this page from our code. Think of this page as the new page you get after launching your chrome browser. In that function, we created an instance of a browser page using puppeteer and stored it in the page constant. First, we created an async function called extractImageLinks. Now let me explain what is happening here. Enter fullscreen mode Exit fullscreen mode
