How to set download behaviour in PuppeteerSharp?

I want to set download behaviour of browser for testing needs

I had tried solution from this topic: puppeteer - how to set download location

var browser = await StartNewChromeAsync(); //starting new chrome without extensions
var pages = await browser.PagesAsync();
var firstPage = pages[0];
var cdp = await firstPage.Target.CreateCDPSessionAsync();
await cdp.SendAsync("Page.setDownloadBehavior", new
                {
                    behavior = "allow",
                    downloadPath = Path.GetAbsolutePath("./testing_downloads")
                });
await cdp.DetachAsync();

I expecting, that files will be downloaded in ./testing_downloads, but it downloadings in default path. What am i doing wrong?

Solution

  • I found no way to do this in modern versions of Chrome because Page.setDownloadBehavior is removed from CDP v1.3 https://chromedevtools.github.io/devtools-protocol/1-3.
