问题
I have 3 different files in my project and the layout is
- phantomjs
- -->phantomjs.js
- -->phantomjs.exe
- index.php
index.php:
$phantom_script = dirname(__FILE__). '\phantomjs\phantomjs.js';
$response = exec ('\phantomjs\phantomjs.exe' . $phantom_script);
echo $response;
phantomjs\phantomjs.js
var webPage = require('webpage');
var page = webPage.create();
page.open('http://www.google.com', function(status) {
console.log(page.content);
phantom.exit();
});
回答1:
your usage oh phantomjs is correct according to the documentation. http://phantomjs.org/api/webpage/property/content.html
php exec method returns the last line only. Maybe that line is a white space. http://php.net/manual/fr/function.exec.php
You shall have a seond parameter &$output, sent by reference. It is an array containing the entire output.
A problem you may face later, the content could need be to evaluated before you try to read it s DOM document content. Using for example innerHTML of HTML tag, ie: $('html').html();
If the page does not have jquery, you may include it, see this example, https://github.com/ariya/phantomjs/blob/master/examples/phantomwebintro.js
Note also that google may actively desire to not let users scrap and save their search results. Not sure about that.
