web-scraping - 通过 PHP-PhantomJS 将脚本传递给 PhantomJS 的正确方法？

Question

我正在学习 PhantomJS 和 PHP-PhantomJS。我想将脚本传递给 PhantomJS。

目前我正在尝试这个：

   $client->getEngine()->addOption('/Applications/myWebApp/js/phantomtest.js');
    $request = $client->getMessageFactory()->createRequest('http://www.jonnyw.me/', 'GET');

    $response = $client->getMessageFactory()->createResponse();
    $client->send($request, $response);
    if ($response->getStatus() === 200) {
        echo $response->getContent();
    }

$response在调用$client->send($request, $response).

Here's the contents of my test script ('phantomtest.js'):

var page = require('webpage').create();
page.open('http://www.jonnyw.me', function(status) {
  console.log("Status: " + status);
  if(status === "success") {
    page.render('example.png');
  }
  phantom.exit();
});

我认为这一定是文档中的相关页面：http: //jonnnnyw.github.io/php-phantomjs/4.0/4-custom-scripts/

这是有效的代码：

在 PHP 中：

    $location = '/Applications/myWebApp/js/';
    $serviceContainer = ServiceContainer::getInstance();

    $procedureLoader = $serviceContainer->get('procedure_loader_factory')
            ->createProcedureLoader($location);
    $client->getProcedureLoader()->addLoader($procedureLoader);

    $request = $client->getMessageFactory()->createRequest();
    $client->setProcedure('phantomJStest');

    $response = $client->getMessageFactory()->createResponse();

    $client->send($request, $response);

    if (($response->getStatus() === 200) || ($response->getStatus() == 'success')){
        // Dump the requested page content
        echo $response->getContent();
    }

在 proc 文件中phantomJStest.proc：

phantom.onError = function (msg, trace) {
    console.log(JSON.stringify({
      "status": msg
    }));
    phantom.exit(1);
};

var system = require('system');
var uri = "http://www.jonnyw.me";

var page = require('webpage').create();
page.open(uri, function (status) {
    console.log(JSON.stringify({
      "status": status
    }));

    if (status === "success") {
        page.render('example.png');
    }
    phantom.exit(1);
});
