javascript - 如何将 simple_html_dom 与 phantomjs 一起使用

Question

我试图让这两个库相互协作，我当前的代码如下所示:

phantomjs.js

var page = require('webpage').create();
var system = require('system');
var address = system.args[1]; 
page.open(address, function () {
    var content = page.content;
    console.log(content);
    phantom.exit();
 }); 

scraper.php

exec('phantomjs assets/phantomjs.js '.$page, $output);
$html2 = str_get_html($output);

我得到的返回是这样的:

返回错误的 simple_html_dom 函数:

// remove noise from html content
// save the noise in the $this->noise array.
protected function remove_noise($pattern, $remove_tag=false)
{
    global $debugObject;
    if (is_object($debugObject)) { $debugObject->debugLogEntry(1); }

    $count = preg_match_all($pattern, $this->doc, $matches, PREG_SET_ORDER|PREG_OFFSET_CAPTURE);

    for ($i=$count-1; $i>-1; --$i)
    {
        $key = '___noise___'.sprintf('% 5d', count($this->noise)+1000);
        if (is_object($debugObject)) { $debugObject->debugLog(2, 'key is: ' . $key); }
        $idx = ($remove_tag) ? 0 : 1;
        $this->noise[$key] = $matches[$i][$idx][0];
        $this->doc = substr_replace($this->doc, $key, $matches[$i][$idx][1], strlen($matches[$i][$idx][0]));
    }

    // reset the length of content
    $this->size = strlen($this->doc);
    if ($this->size>0)
    {
        $this->char = $this->doc[0];
    }
}

当我使用var_dump($output)时，我得到了网站的html，所以我知道该命令正在工作，但 simple_html_dom 似乎不接受它!

问题是这样的:$output 是数组，但 str_get_html 需要一个字符串作为参数。因此，请确保在解析 $output 之前将其转换为字符串。
