Documenting the `selenium-wire` "Wire Mode" REPLACEMENT

Documenting the selenium-wire "Wire Mode" REPLACEMENT.

There was previously a selenium-wire integration via SeleniumBase Wire Mode, (was removed).

There were two main issues with it:

Here's the good news: selenium-wire features are included in the new SeleniumBase CDP Mode.

Here's an example of that, (SeleniumBase/examples/cdp_mode/raw_res_sb.py), where network requests and responses are captured and displayed:

python
"""Using CDP.network.RequestWillBeSent and CDP.network.ResponseReceived."""
import colorama
import mycdp
import sys
from seleniumbase import SB

c1 = colorama.Fore.BLUE + colorama.Back.LIGHTYELLOW_EX
c2 = colorama.Fore.BLUE + colorama.Back.LIGHTGREEN_EX
cr = colorama.Style.RESET_ALL
if "linux" in sys.platform:
    c1 = c2 = cr = ""

async def send_handler(event: mycdp.network.RequestWillBeSent):
    r = event.request
    s = f"{r.method} {r.url}"
    for k, v in r.headers.items():
        s += f"\n\t{k} : {v}"
    print(c1 + "*** ==> RequestWillBeSent <== ***" + cr)
    print(s)

async def receive_handler(event: mycdp.network.ResponseReceived):
    print(c2 + "*** ==> ResponseReceived <== ***" + cr)
    print(event.response)

with SB(uc=True, test=True, locale="en") as sb:
    sb.activate_cdp_mode("about:blank")
    sb.add_handler(mycdp.network.RequestWillBeSent, send_handler)
    sb.add_handler(mycdp.network.ResponseReceived, receive_handler)
    url = "https://seleniumbase.io/apps/calculator"
    sb.goto(url)
    sb.sleep(1)

Usage is different from regular Selenium-Wire, but it can do all the same things (and more) with better flexibility/control.

Here's another example, (SeleniumBase/examples/cdp_mode/raw_req_sb.py), where specific requests were filtered out (intercepted and blocked), to prevent images from loading:

python
"""Using CDP.fetch.RequestPaused to filter content in real-time."""
import colorama
import mycdp
import sys
from seleniumbase import SB

c1 = colorama.Fore.RED + colorama.Back.LIGHTYELLOW_EX
c2 = colorama.Fore.BLUE + colorama.Back.LIGHTCYAN_EX
cr = colorama.Style.RESET_ALL
if "linux" in sys.platform:
    c1 = c2 = cr = ""

async def request_paused_handler(event, tab):
    r = event.request
    is_image = ".png" in r.url or ".jpg" in r.url or ".gif" in r.url
    if not is_image:  # Let the data through
        tab.feed_cdp(mycdp.fetch.continue_request(request_id=event.request_id))
    else:  # Block the data (images)
        TIMED_OUT = mycdp.network.ErrorReason.TIMED_OUT
        s = f"{c1}BLOCKING{cr} | {c2}{r.method}{cr} | {r.url}"
        print(f" >>> ------------\n{s}")
        tab.feed_cdp(mycdp.fetch.fail_request(event.request_id, TIMED_OUT))

with SB(uc=True, test=True, locale="en") as sb:
    sb.activate_cdp_mode("about:blank")
    sb.add_handler(mycdp.fetch.RequestPaused, request_paused_handler)
    url = "https://gettyimages.com/photos/firefly-2003-nathan"
    sb.goto(url)
    sb.sleep(4)

For more examples of intercepting and modifying requests & responses, see the CDP Mode folder.
