Rendering Javascript

Learn to scrape JavaScript-rendered pages using ScraperAPI in PHP. Enable headless browser rendering with render=true for dynamic content, SPAs, and JS-heavy sites.

If you are crawling a page that requires you to render the Javascript on the page to scrape the data you need, then we can fetch these pages using a headless browser.

To render Javascript, simply set render=true and we will use a headless Google Chrome instance to fetch the page. This feature is available on all plans.

Pass the JavaScript rendering parameter within the URL:

• API REQUEST

<?php $url =
"http://api.scraperapi.com?api_key=APIKEY&url=http://httpbin.org/ip&render=true"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER,
TRUE); curl_setopt($ch, CURLOPT_HEADER,
FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,
0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,
0); $response = curl_exec($ch); curl_close($ch); print_r($response);

• PROXY MODE

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://httpbin.org/ip");
curl_setopt($ch, CURLOPT_PROXY, "http://scraperapi.render=true:[email protected]:8001");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);

• SDK Method

# remember to install the library: composer require scraperapi/sdk
<?php
$client = new ScraperAPIClient("APIKEY");
$result = $client->get("http://httpbin.org/ip", ["render" => true])->raw_body;
print($result);

Pass the parameter in the headers:

• API REQUEST

<?php
$url = "https://api.scraperapi.com?url=https://httpbin.org/ip";
$ch = curl_init();

$headers = array(
    'x-sapi-render: true',
    'x-sapi-api_key: <YOUR_API_KEY>'
);

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

$response = curl_exec($ch);

curl_close($ch);

print_r($response);
?>

• PROXY MODE

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://httpbin.org/ip");
curl_setopt($ch, CURLOPT_PROXY, "http://scraperapi:<YOUR_API_KEY>@proxy-server.scraperapi.com:8001");
$headers = array('x-sapi-render: true');
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

$response = curl_exec($ch);

curl_close($ch);

print_r($response);
?>

• SDK Method

# remember to install the library: composer require scraperapi/sdk
<?php
$client = new ScraperAPIClient("APIKEY");
$result = $client->get("http://httpbin.org/ip", [
'headers' => ['x-sapi-render' => 'true']])->raw_body;
print($result);
?>
