Rendering Javascript

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.

• API REQUEST

import requests
payload = {'api_key': 'APIKEY', 'url':'https://httpbin.org/ip', 'render': 'true'}
r = requests.get('http://api.scraperapi.com', params=payload)
print(r.text)

# Scrapy users can simply replace the urls in their start_urls and parse function
# ...other scrapy setup code
start_urls = ['http://api.scraperapi.com?api_key=APIKEY&url=' + url + '&render=true']

def parse(self, response):
# ...your parsing logic here
yield scrapy.Request('http://api.scraperapi.com/?api_key=APIKEY&url=' + url + '&render=true', self.parse)

• PROXY MODE

import requests
proxies = {
  "http": "http://scraperapi.render=true:[e-mail]:8001"
}
r = requests.get('http://httpbin.org/ip', proxies=proxies, verify=False)
print(r.text)

# Scrapy users can likewise simply pass their API key in headers.
# NB: Scrapy skips SSL verification by default.
# ...other scrapy setup code
start_urls = ['http://httpbin.org/ip']
meta = {
  "proxy": "http://scraperapi.render=true:[e-mail]:8001"
}
def parse(self, response):
# ...your parsing logic here
yield scrapy.Request(url, callback=self.parse, headers=headers, meta=meta)

• SDK Method

from scraperapi_sdk import ScraperAPIClient
client = ScraperAPIClient('APIKEY')
result = client.get(url = 'http://httpbin.org/ip', render=true).text
print(result)

# Scrapy users can simply replace the urls in their start_urls and parse function
# Note for Scrapy, you should not use DOWNLOAD_DELAY and
# RANDOMIZE_DOWNLOAD_DELAY, these will lower your concurrency and are not
# needed with our API

# ...other scrapy setup code
start_urls =[client.scrapyGet(url = 'http://httpbin.org/ip', render=true)]
def parse(self, response):

# ...your parsing logic here
yield scrapy.Request(client.scrapyGet(url = 'http://httpbin.org/ip', render=true), self.parse)
