Usage
Plain text scraping
import asyncio
import json

from aioscrapy import Client, WebTextClient, SingleSessionPool, Dispatcher, SimpleWorker

class CustomClient(Client[str, dict]):
def __init__(self, client: WebTextClient):
self._client = client

async def fetch(self, key: str) -> dict:
data = await self._client.fetch(key)
return json.loads(data)

async def main():
pool = SingleSessionPool()
dispatcher = Dispatcher(['https://httpbin.org/get'])
client = CustomClient(WebTextClient(pool))
worker = SimpleWorker(dispatcher, client)

result = await worker.run()
return result

loop = asyncio.get_event_loop()
print(loop.run_until_complete(main()))

Byte content downloading
import asyncio

from aioscrapy import Client, WebByteClient, SingleSessionPool, Dispatcher, SimpleWorker

class CustomClient(Client[str, bytes]):
def __init__(self, client: WebByteClient):
self._client = client

async def fetch(self, key: str) -> bytes:
data = await self._client.fetch(key)
return data

async def main():
pool = SingleSessionPool()
dispatcher = Dispatcher(['https://httpbin.org/image'])
client = CustomClient(WebByteClient(pool))
worker = SimpleWorker(dispatcher, client)

result = await worker.run()
return result

loop = asyncio.get_event_loop()
data: dict = loop.run_until_complete(main())
for url, byte_content in data.items():
print(url + ": " + str(len(byte_content)) + " bytes")
