How to catch data from the post request

[cpamaster]

Hello. One page make a post request and receive json data. How to get this data by chrome-php?

You didn't specify how the data is received but you can intercept any request using the event method:Network.requestIntercepted. See #73 (comment) for an example.

Data is coming by xhr request.
I found one solution to catch all ajax results:

(function() {
    var open = XMLHttpRequest.prototype.open;
    XMLHttpRequest.prototype.open = function(method, url, async, user, password) {
        if (async) {
            this.onreadystatechange = function() {
                if (this.readyState == 4) {
                   // this.responseText - ajax result
                }
            }
        }
        return open.apply(this, arguments);
    }
})();

@cpamaster that would only catch XHR's.
Simplifying the example @enricodias linked to and created by @ethaniel , try

$page->getSession()->on('method:Network.requestIntercepted', function (array $params) use($page): void {
    // here you will get all info about the request :)
    var_dump($params);
    //
    $page->getSession()->sendMessage(
        new \HeadlessChromium\Communication\Message('Network.continueInterceptedRequest', [
            'interceptionId' => $params["interceptionId"]
        ])
    );
});
// Intercept all requests
$page->getSession()->sendMessage(
    new \HeadlessChromium\Communication\Message('Network.setRequestInterception', [
        'patterns' => [['urlPattern' => '*']]
    ])
);
