Installing

• [Windows] Install Chrome-Browser
• pip install cdp-socket

CDPSocket

from cdp_socket.utils.utils import launch_chrome, random_port
from cdp_socket.socket import CDPSocket

import os
import asyncio


def on_detached(params):
    print("Detached with: ", params)


async def main():
    PORT = random_port()
    process = launch_chrome(PORT)
    
    async with CDPSocket(PORT) as base_socket:
        targets = await base_socket.targets
        sock1 = await base_socket.get_socket(targets[0])
        targets = await sock1.exec("Target.getTargets")
        print(targets)
    os.kill(process.pid, 15)


asyncio.run(main())

Single socket

from cdp_socket.utils.utils import launch_chrome, random_port
from cdp_socket.utils.conn import get_websock_url

from cdp_socket.socket import SingleCDPSocket

import os
import asyncio


async def main():
    PORT = random_port()
    process = launch_chrome(PORT)

    websock_url = await get_websock_url(PORT, timeout=5)
    async with SingleCDPSocket(websock_url, timeout=5) as sock:
        targets = await sock.exec("Target.getTargets")
        print(targets)

    os.kill(process.pid, 15)


asyncio.run(main())

on_closed callback

from cdp_socket.socket import SingleCDPSocket

def on_closed(code, reason):
    print("Closed with: ", code, reason)

async with SingleCDPSocket(websock_url, timeout=5) as sock:
    sock.on_closed.append(on_closed)
    # close window for dispatching this event
    targets = await sock.exec("Target.getTargets")
    print(targets)

add event listener

from cdp_socket.socket import SingleCDPSocket
import asyncio

def on_detached(params):
    print("Detached with: ", params)
    
async with SingleCDPSocket(websock_url, timeout=5) as sock:
        # close window for dispatching this event
        sock.add_listener('Inspector.detached', on_detached)
        await asyncio.sleep(1000)

iterate over event

from cdp_socket.socket import SingleCDPSocket

async with SingleCDPSocket(websock_url, timeout=5) as sock:
    async for i in sock.method_iterator('Inspector.detached'):
        print(i)
        break

wait for event

from cdp_socket.socket import SingleCDPSocket

async with SingleCDPSocket(websock_url, timeout=5) as sock:
    res = await sock.wait_for('Inspector.detached')
    print(res)
