Blocking network urls in uc mode

[iohansson]

I'm blocking some urls with execute_cdp_cmd and it seems that it doesn't work. I suspect that this is because of the reconnect. Network.setBlockedURLs and Network.enable approach works with undetected_chromedriver but not seleniumbase.
What would be a proper way of blocking resources? The goal is to save traffic when using a proxy.

The methods like uc_open_with_tab(url) and uc_open_with_reconnect(url, reconnect_time) open URLs in a new tab. However, execute_cdp_cmd() only affects the current tab. You can get around that by using uc_open(url) after you've called execute_cdp_cmd() (or if you refresh the page).

Hmm, that was my first thought to try that :) And it didn't help, could you check if it works for you currently?

from seleniumbase import BaseCase
BaseCase.main(__name__, __file__, "--uc")


class TestGeolocation(BaseCase):
    def tearDown(self):
        self.save_teardown_screenshot()  # If test fails, or if "--screenshot"
        if self.is_chromium() and not self._multithreaded:
            # Reset Permissions and GeolocationOverride
            try:
                self.open("about:blank")
                self.execute_cdp_cmd("Emulation.setGeolocationOverride", {})
                self.execute_cdp_cmd("Browser.resetPermissions", {})
            except Exception:
                pass
        super().tearDown()

    def test_geolocation(self):
        self.open("about:blank")
        if self._multithreaded:
            self.skip("Skipping test in multi-threaded mode.")
        if not self.is_chromium():
            print("\n* execute_cdp_cmd() is only for Chromium browsers")
            self.skip("execute_cdp_cmd() is only for Chromium browsers")
        self.driver.uc_open("https://www.openstreetmap.org/")
        self.execute_cdp_cmd(
            "Browser.grantPermissions",
            {
                "origin": "https://www.openstreetmap.org/",
                "permissions": ["geolocation"],
            },
        )
        self.execute_cdp_cmd(
            "Emulation.setGeolocationOverride",
            {
                "latitude": 48.87645,
                "longitude": 2.26340,
                "accuracy": 100,
            },
        )
        self.refresh()
        self.click("span.geolocate")
        self.assert_url_contains("48.87645/2.26340")
        self.save_screenshot_to_logs()
        if self.headed:
            self.sleep(2.5)

Thanks! I wasn't using the BaseCase, just the driver, do I have to? Is self.execute_cdp_cmd just a proxy for the same method on the driver or not?

The BaseCase methods can also be reached from the SB() / sb format. Eg:

from seleniumbase import SB

with SB() as sb:
    sb.open("seleniumbase.io/simple/login")
    sb.type("#username", "demo_user")
    sb.type("#password", "secret_pass")
    sb.click('a:contains("Sign in")')
    sb.assert_exact_text("Welcome!", "h1")
    sb.assert_element("img#image1")
    sb.highlight("#image1")
    sb.click_link("Sign out")
    sb.assert_text("signed out", "#top_message")

The SB() methods are more advanced than the Driver() methods. (The Driver() methods are basically what comes with Selenium, with a few extra methods added in for simplification.) You can also reach the Driver() methods from the SB() format by calling sb.driver. For some methods that can be found in both formats, the SB() version is often more powerful than the Driver() version.

ok, I'll give it a shot, thank you!
