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. It allows you to simulate user interaction with a browser through a simple API. It’s a piece of open-source software developed and supported by Google’s developer tools team. Var cookieContainer = new CookieContainer() ĬookieContainer.Add(new Cookie(cookie.Name, cookie.Value, cookie.Path, cookie.Domain)) What is Puppeteer Simply put, Puppeteer is a software for controlling a (headless) browser. 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 When installed, it downloads a version of Chrome, which it then drives using puppeteer-core. If (contentType.Contains("application/vnd.ms-excel")) puppeteer is a product for browser automation. 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()) The page size can be customized with tViewport(). 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. Puppeteer sets an initial page size to 800×600px, which defines the screenshot size. In essence, before the button click, I had to process multiple responses and handle a single response with the download. Puppeteer: Download Chromium for different platforms javascript node. The browser is downloaded to the HOME/.cache/puppeteer folder by default. I needed both Headers and Cookies set before the download would start. GitHub - puppeteer/examples: Use case-driven examples for using Puppeteer and headless chrome puppeteer / examples Public Notifications Fork 308 2. Puppeteer is a Node.js library which provides a high-level API to control. Here we generate a CSV file and have the browser download it await page.I had a more difficult variation of this, using Puppeteer Sharp.
