Sending custom cookies

from scrapingant_client import ScrapingAntClient
from scrapingant_client import Cookie

client = ScrapingAntClient(token='<YOUR-SCRAPINGANT-API-TOKEN>')

result = client.general_request(
    'https://httpbin.org/cookies',
    cookies=[
        Cookie(name='cookieName1', value='cookieVal1'),
        Cookie(name='cookieName2', value='cookieVal2'),
    ]
)
print(result.content)
# Response cookies is a list of Cookie objects
# They can be used in next requests
response_cookies = result.cookies 

Executing custom JS snippet

from scrapingant_client import ScrapingAntClient

client = ScrapingAntClient(token='<YOUR-SCRAPINGANT-API-TOKEN>')

customJsSnippet = """
var str = 'Hello, world!';
var htmlElement = document.getElementsByTagName('html')[0];
htmlElement.innerHTML = str;
"""
result = client.general_request(
    'https://example.com',
    js_snippet=customJsSnippet,
)
print(result.content)

Exception handling and retries

from scrapingant_client import ScrapingAntClient, ScrapingantClientException, ScrapingantInvalidInputException

client = ScrapingAntClient(token='<YOUR-SCRAPINGANT-API-TOKEN>')

RETRIES_COUNT = 3


def parse_html(html: str):
    ...  # Implement your data extraction here


parsed_data = None
for retry_number in range(RETRIES_COUNT):
    try:
        scrapingant_response = client.general_request(
            'https://example.com',
        )
    except ScrapingantInvalidInputException as e:
        print(f'Got invalid input exception: {{repr(e)}}')
        break  # We are not retrying if request params are not valid
    except ScrapingantClientException as e:
        print(f'Got ScrapingAnt exception {repr(e)}')
    except Exception as e:
        print(f'Got unexpected exception {repr(e)}')  # please report this kind of exceptions by creating a new issue
    else:
        try:
            parsed_data = parse_html(scrapingant_response.content)
            break  # Data is parsed successfully, so we dont need to retry
        except Exception as e:
            print(f'Got exception while parsing data {repr(e)}')

if parsed_data is None:
    print(f'Failed to retrieve and parse data after {RETRIES_COUNT} tries')
    # Can sleep and retry later, or stop the script execution, and research the reason 
else:
    print(f'Successfully parsed data: {parsed_data}')

Sending custom headers

from scrapingant_client import ScrapingAntClient

client = ScrapingAntClient(token='<YOUR-SCRAPINGANT-API-TOKEN>')

result = client.general_request(
    'https://httpbin.org/headers',
    headers={
        'test-header': 'test-value'
    }
)
print(result.content)

# Http basic auth example
result = client.general_request(
    'https://jigsaw.w3.org/HTTP/Basic/',
    headers={'Authorization': 'Basic Z3Vlc3Q6Z3Vlc3Q='}
)
print(result.content)

Simple async example

import asyncio

from scrapingant_client import ScrapingAntClient

client = ScrapingAntClient(token='<YOUR-SCRAPINGANT-API-TOKEN>')


async def main():
    # Scrape the example.com site.
