PHP客户端，用于Chrome Devtools Protocol。

安装

composer require fyrts/chrome-devtools-protocol

基本用法

// context creates deadline for operations
$ctx = Context::withTimeout(Context::background(), 30 /* seconds */);

// launcher starts chrome process ($instance)
$launcher = new Launcher();
$instance = $launcher->launch($ctx);

try {
	// work with new tab
	$tab = $instance->open($ctx);
	$tab->activate($ctx);

	$devtools = $tab->devtools();
	try {
		$devtools->page()->enable($ctx);
		$devtools->page()->navigate($ctx, NavigateRequest::builder()->setUrl("https://www.google.com/")->build());
		$devtools->page()->awaitLoadEventFired($ctx);

		// ... work with page ...
		// e.g.
		// - print to PDF: $devtools->page()->printToPDF($ctx, PrintToPDFRequest::make());
		// - capture screenshot: $devtools->page()->captureScreenshot($ctx, CaptureScreenshotRequest::builder()->setFormat("jpg")->setQuality(95)->build());

	} finally {
		// devtools client needs to be closed
		$devtools->close();
	}

} finally {
	// process needs to be killed
	$instance->close();
}

无头Chrome的独立上下文

无头Chrome支持一个名为browser contexts的功能——它们类似于隐身窗口——cookie、本地存储等不被共享。在browser context被销毁后，在该上下文中创建的用户数据也会被销毁。

与隐身窗口不同，可以同时存在多个隔离的browser contexts。

$ctx = Context::withTimeout(Context::background(), 10);
$launcher = new Launcher();
$instance = $launcher->launch($ctx);
try {
	$session = $instance->createSession($ctx);
	try {

		// $session implements DevtoolsClientInterface, same as returned from Tab::devtools()

	} finally {
		$session->close();
	}
} finally {
	$instance->close();
}
