Keyword argument style options (more pythonic, isn't it?): browser = await launch ( headless = True ) Element selector method names Open web page and take a screenshot: import asyncio from pyppeteer import launch async def main (): browser = await launch () page = await browser. Puppeteer's documentation and its troubleshooting guide are also great resources for pyppeteer users. One way to do this is to run pyppeteer-install command before prior to using this library.įull documentation can be found here. If you don't prefer this behavior, ensure that a suitable Chrome binary is installed.

If (atag & atag.textContent = '在文件夹中显示'), // polling? yes.Note: this is a continuation of the pyppeteer project. if finish than return true if fail clickĬonst dm = document.querySelector('downloads-manager').shadowRootĬonst firstItem = dm.querySelector('#frb0')Ĭonst thatArea = ('.controls') monitoring the state of the first download item
But you can easily adapt it to 'infinite threads' by iterating through all download items ( #frb0~ #frbn) in that page, well, take care of your network:) dmPage = await browser.newPage()Īwait your_download_button.click() // start downloadĪwait dmPage.bringToFront() // this is necessary This example is 'single thread' currently, because it's only monitoring the first item appear in the download manager page. This solution can be very easily to auto restart a failed download using chrome's own feature My solution is to use chrome's own chrome://downloads/ page to managing download files. It also has 'smarter' locator, which examine selectors every time before click() Use Playwright to get away from this mass.
