This will set the default download directory for files before the process starts. _directory = path.resolve(_dirname, './downloads') įs.writeFileSync(customChrome+'/Default/Preferences', JSON.stringify(obj)) Īrgs: _directory = path.resolve(_dirname, './downloads') Let prefs = fs.readFileSync(customChrome+'/Default/Preferences') I was able to set the download location using the following code, let customChrome = path.resolve(_dirname, './customChrome') 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.I realize this is an old thread, but this thread popped up first for me when looking for how to set Puppeteer default download location. 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() 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. I had a more difficult variation of this, using Puppeteer Sharp.
