[PHP-] PhantomJS – 自动检测给定高度的页面高度

我喜欢设置宽度,并相应地自动检测每页的高度.由于我正在处理一系列URL,因此每个页面的高度都是动态的.

有人有运气吗？我当前的版本如下所示：

public function takeScreenshots($site,$newDir,$dimensions) {
    $urlHost = parse_url($site)["host"];
    $urlPath = isset(parse_url($site)['path']) ? parse_url($site)['path'] : '';
    $urlPathName = str_replace("/","",$urlPath);
    $filepath = $newDir . $urlHost . "_" . $urlPathName . ".jpg";

    $client = Client::getInstance();
    $client->getEngine()->setPath(base_path().'/bin/phantomjs');

    $width  = $dimensions["width"];
    $height = $dimensions["height"];
    $top    = 0;
    $left   = 0;

    $request = $client->getMessageFactory()->createCaptureRequest($site,'GET');
    $request->setOutputFile($filepath);
    $request->setViewportSize($width,$height);
    $request->setCaptureDimensions($width,$height,$top,$left);
    $response = $client->getMessageFactory()->createResponse();
    $client->send($request,$response);
}
