webdriver error "urllib3.exceptions.ProxySchemeUnknown: Proxy URL had no scheme, should start w-CodePudding

I'm new to python, when I want to run following simple code I got error:

from selenium import webdriver

browser = webdriver.Firefox()
browser.get("http://www.whatsmyip.org")

error:

Traceback (most recent call last):

    raise ProxySchemeUnknown(proxy.scheme)
urllib3.exceptions.ProxySchemeUnknown: Proxy URL had no scheme, should start with http:// or https://

Thank you in advance for your guidance.

CodePudding user response：

This error appears when your client code (your test) attempts to send a command to a WebDriver service. Since it is REST (over http) Selenium takes the proxy that is defined in environment variable for corresponding protocol:

def _get_proxy_url(self):
    if self._url.startswith('https://'):
        return os.environ.get('https_proxy', os.environ.get('HTTPS_PROXY'))
    elif self._url.startswith('http://'):
        return os.environ.get('http_proxy', os.environ.get('HTTP_PROXY'))

Looks like the value that is assigned to one of (or both) those vars is not a proper URL.

The solution would be:

either to fix the URL
or to toggle ignore_local_proxy_environment_variables in FirefoxOptions
