![]() 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) Being an end-user product, puppeteer automates several workflows using reasonable defaults that can be customized. ![]() When installed, it downloads a version of Chrome, which it then drives using puppeteer-core. NEED THIS TIMEOUT TO KEEP THE BROWSER OPEN WHILE THE FILE IS DOWNLOADING!Īwait page.WaitForTimeoutAsync(1000 * configs.DownloadDurationEstimateInSeconds) puppeteer is a product for browser automation. Var cookieContainer = BuildCookieContainer(pageCookies) Īwait DownloadFileRequiringHeadersAndCookies(getUrl, fullPath, cookieContainer, cancellationToken) Īwait page.ClickAsync("button") Be sure that the version of puppeteer-core you install is compatible with the browser you intend to connect to. Var pageCookies = await page.GetCookiesAsync() puppeteer-core is intended to be a lightweight version of Puppeteer for launching an existing browser installation or for connecting to a remote one. 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) => puppeteer-core is a library to help drive anything that supports DevTools protocol. Handle multiple responses and process the Download When installed, it downloads a version of Chrome, which it then drives using puppeteer-core. 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. I had a more difficult variation of this, using Puppeteer Sharp. Puppeteer is a headless Node library that provides a high level API for controlling Chromium or Chrome over the DevTools protocol.
