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. Install Puppeteer Core ( puppetter-core) package.I had a more difficult variation of this, using Puppeteer Sharp. I will create the script that use puppeteer-core to show my Google Chrome version. I don't know what current version of Google Chrome installed. I am using Ubuntu 19.10 eoan and I already have Google Chrome installed and now I want to try puppeteer-core. We will show this later on the source code. Technically we have to define executablePath option that contains the Chrome or Chromium browser path. The difference between puppeteer and puppeteer-core in the term of launch settings is we have to define the Chrome or Chromium browser executable path.
I am sure for general use case it will work. And again according to documentation said below.īe sure that the version of puppeteer-core you install is compatible with the browser you intend to connect to. What does it means? It means you can use existing Chrome or Chromium browser for browsing automation with Puppeteer. It available since Puppeteer version 1.7.0.
Today we will try to use Puppeteer Core (package name puppeteer-core), a version of Puppeteer that doesn't download Chromium by default. Note: When you install Puppeteer, it downloads a recent version of Chromium (~170MB Mac, ~282MB Linux, ~280MB Win) that is guaranteed to work with the API. So it's quite big download size and usually takes long time during installation. If you used to play with Puppetter, you must be already know that when installing Puppeteer (with npm i puppeteer) it will install recent version of Chromium browser.
