[HELP] JsFunction and download process

[wislem]

Hello,

Great job on the package, works like a charm!

My issue has to do more than usage rather than a bug report.

I have managed to go through the log in and navigation process in my DFP account and am now trying to download a CSV file from in there.

The download is triggered through a button that sends a POST request and the actual path of the file is returned in the response of that request. Then a new tab opens and the download dialog opens.

I would love to download the file in the disk, meaning, continue using puppeteer on the newly opened tab and download it. For now I just tried to get the response. Any advice on the download process would be greatly appreciated!

    $page = $this->login(true);

    // Navigation, working just fine!
    $page->click('.sidebar-options .section:nth-child(7) a.section-title');
    $page->click('a[href="#admin/policy-center"]');
    $page->click('a[href="#admin/policy-download"]');
    $page->click('dropdown-button._ngcontent-ADMIN-3._nghost-ADMIN-4');
    $page->click('dropdown-button._ngcontent-ADMIN-3._nghost-ADMIN-4');
    $page->click('.options-wrapper > div[group] > material-select-dropdown-item:nth-child(2)');
    $page->click('div.download');
    // Here is where the POST request occurs

    $page->waitFor(2*1000);

    // How wrong is this? :)
    $response = $page->on('response', ['pageResponse' => JsFunction::create('pageResponse', "
        if ('xhr' !== response.request().resourceType()){
            return ;
        }
        response.text().then(function (textBody) {
            return textBody;
        })
    ")]);

    dd($response);

I am getting the error below:

Nesk\Rialto\Exceptions\Node\FatalException: The "listener" argument must be of type Function in file D:\workspace\laragon\www\ocmbots\vendor\nesk\rialto\src\ProcessSupervisor.php on line 230

Screenshot of the post request and response when the download button is clicked:

Environment (please complete the following information):

• OS: Windows 10
• Node version: 9.2.0
• PHP version 7.2.2

My Node package manager is:
NPM 6.1.0

Your a bit out of luck here… 😕

First, it seems like Puppeteer itself doesn't really support file downloads for the moment.

Second, it's not currently possible for PuPHPeteer to retrieve a value from an event, this is partially due to the lack of concurrency in PHP. This could be solved by implementing some kind of “value retriever” in Rialto, but I have to think properly about this before writing anything. If I find a good solution, I will notify you. 🙂

I'm closing the issue since this mainly concerns Rialto instead of PuPHPeteer, but feel free to answer.

Is there any update on this?

I've created an issue about this a few days ago, to present a potential solution and track the progress. But I didn't start to write any code and I will probably not start working on this until v2 is out.
