Python SDK

Python SDK gives you a handy abstraction to interact with Scrapfly API. It includes all of scrapfly features and many convenient shortcuts:

Automatic base64 encode of JS snippet
Error Handling
Body json encode if Content-Type: application/json
Body URL encode and set Content Type: application/x-www-form-urlencoded if no content type specified
Convert Binary response into a python ByteIO object

Step by Step Introduction

For a hands-on introduction see our Scrapfly SDK introduction page!

The Full python API specification is available here: https://scrapfly.github.io/python-scrapfly/docs/scrapfly

For more on Python SDK use with Scrapfly, select "Python SDK" option in Scrapfly docs top bar.

Installation

Source code of Python SDK is available on Github scrapfly-sdk package is available through PyPi.

pip install 'scrapfly-sdk'

You can also install extra package scrapfly[speedups] to get brotli compression and msgpack serialization benefits.

pip install 'scrapfly-sdk[speedups]'

Scrape

If you plan to scrape protected website - make sure to enable Anti Scraping Protection

from scrapfly import ScrapeConfig, ScrapflyClient, ScrapeApiResponse

scrapfly = ScrapflyClient(key='')

api_response:ScrapeApiResponse = scrapfly.scrape(scrape_config=ScrapeConfig(url='https://httpbin.dev/anything'))

# Automatic retry errors marked "retryable" and wait delay recommended before retrying
api_response:ScrapeApiResponse = scrapfly.resilient_scrape(scrape_config=ScrapeConfig(url='https://httpbin.dev/anything'))

# Automatic retry error based on status code
api_response:ScrapeApiResponse = scrapfly.resilient_scrape(scrape_config=ScrapeConfig(url='https://httpbin.dev/status/500'), retry_on_status_code=[500])

# scrape result, content, iframes, response headers, response cookies states, screenshots, ssl, dns etc
print(api_response.scrape_result)

# html content
print(api_response.scrape_result['content'])

# Context of scrape, session, webhook, asp, cache, debug
print(api_response.context)

# raw api result
print(api_response.content)

# True if the scrape respond with >= 200 < 300 http status
print(api_response.success)

# Api status code /!\ Not the api status code of the scrape!
print(api_response.status_code)

# Upstream website status code
print(api_response.upstream_status_code)

# Convert API Scrape Result into well known requests.Response object
print(api_response.upstream_result_into_response())

API response : https://scrapfly.github.io/python-scrapfly/scrapfly/api_response.html

Using Context

from scrapfly import ScrapeConfig, ScrapflyClient, ScrapeApiResponse

scrapfly = ScrapflyClient(key='')

with scrapfly as scraper:
    response: ScrapeApiResponse = scraper.scrape(ScrapeConfig(url='https://httpbin.dev/anything', country='fr'))

How to configure Scrape Query

You can check the ScrapeConfig implementation to check all available options available here.

All parameters listed in this documentation can be used when you construct the scrape config object.

Download Binary Response

from scrapfly import ScrapflyClient, ScrapeApiResponse

api_response:ScrapeApiResponse = scrapfly.scrape(scrape_config=ScrapeConfig(url='https://www.intel.com/content/www/us/en/ethernet-controllers/82599-10-gbe-controller-datasheet.html'))
scrapfly.sink(api_response) # you can specify path and name via named arguments

Error Handling

Error handling is a big part of scraper, so we design a system to reflect what happened when it's going bad to handle it properly from Scraper. Here a simple snippet to handle errors on your owns

from scrapfly import ScrapeConfig, ScrapflyClient, ScrapeApiResponse, UpstreamHttpClientError, \
ScrapflyScrapeError, UpstreamHttpServerError


scrapfly = ScrapflyClient(key='')

try:
    api_response:ScrapeApiResponse = scrapfly.scrape(scrape_config=ScrapeConfig(
        url='https://httpbin.dev/status/404',
    ))
except UpstreamHttpClientError as e: # HTTP 400 - 500
    print(e.api_response.scrape_result['error'])
    raise e
except UpstreamHttpServerError as e:  # HTTP >= 500
    print(e.api_response.scrape_result['error'])
    raise e
# UpstreamHttpError can be used to catch all related error regarding the upstream website
except ScrapflyScrapeError as e:
    print(e.message)
    print(e.code)
    raise e

Errors with related code and explanation are documented and available here, if you want to know more.

scrapfly.UpstreamHttpClientError Upstream website that you scrape response with http code >= 300 < 400
scrapfly.UpstreamHttpServerError Upstream website that you scrape response with http code >= 500 < 600
scrapfly.ApiHttpClientError Scrapfly API respond with >= 300 < 400
scrapfly.ApiHttpServerError Scrapfly API respond with >= 500 < 600
scrapfly.ScrapflyProxyError Error related to Proxy
scrapfly.ScrapflyThrottleError Error related to Throttle
scrapfly.ScrapflyAspError Error related to ASP
scrapfly.ScrapflyScheduleError Error related to Schedule
scrapfly.ScrapflyWebhookError Error related to Webhook
scrapfly.ScrapflySessionError Error related to Session
scrapfly.TooManyConcurrentRequest Maximum of concurrent request allowed by your plan reached
scrapfly.QuotaLimitReached Quota Limit of your plan or project reached

error.message              # Message
error.code                 # Error code of error
error.retry_delay         # Recommended time wait before retrying if retryable
error.retry_times         # Recommended retry times if retryable
error.resource            # Related resource, Proxy, ASP, Webhook, Spider
error.is_retryable        # True or False
error.documentation_url   # Documentation explaining the error in details
error.api_response        # Api Response object
error.http_status_code    # Http code

By default, if the upstream website that you scrape responds with bad HTTP code, the SDK will raise UpstreamHttpClientError or UpstreamHttpServerError regarding the HTTP status code. You can disable this behavior by setting the raise_on_upstream_error attribute to false. ScrapeConfig(raise_on_upstream_error=False)

If you want to report to your app for monitoring / tracking purpose on your side, checkout reporter feature.

Account

You can retrieve account information

from scrapfly import ScrapflyClient

scrapfly = ScrapflyClient(key='')
print(scrapfly.client.account())

Keep Alive HTTP Session

Take benefits of Keep-Alive Connection

from scrapfly import ScrapeConfig, ScrapflyClient, ScrapeApiResponse

scrapfly = ScrapflyClient(key='')

with scrapfly as client:
    api_response:ScrapeApiResponse = scrapfly.scrape(scrape_config=ScrapeConfig(
        url='https://news.ycombinator.com/',
        render_js=True,
        screenshots={
            'main': 'fullpage'
        }
    ))
    # more scrape calls

Concurrency out of the box

You can run scrape concurrently out of the box. We use asyncio for that.

In python, there are many ways to achieve concurrency. You can also check:

First of all, ensure you have installed concurrency module

pip install 'scrapfly-sdk[concurrency]'

import asyncio

import logging as logger
from sys import stdout

scrapfly_logger = logger.getLogger('scrapfly')
scrapfly_logger.setLevel(logger.DEBUG)
logger.StreamHandler(stdout)

from scrapfly import ScrapeConfig, ScrapflyClient, ScrapeApiResponse

scrapfly = ScrapflyClient(key='', max_concurrency=2)

async def main():
    targets = [
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True),
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True),
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True),
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True),
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True),
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True),
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True),
        ScrapeConfig(url='https://httpbin.dev/anything', render_js=True)
    ]
    async for result in scrapfly.concurrent_scrape(scrape_configs=targets):
        print(result)

asyncio.run(main())
