The python script sets the IE agent through the registry. After verification, it cannot open or close at the same time

Question

see code.I want to open the proxy and then close the proxy. in fact, i find it is normal to turn on proxy and turn off proxy, but they cannot be used at the same time. I haven't found a solution yet. Please help me. Thank you

import ctypes
import winreg
import time
import requests

xpath = "Software\Microsoft\Windows\CurrentVersion\Internet Settings"
internet_set_option = ctypes.windll.Wininet.InternetSetOptionW
def setProxy(enable, proxy):
    try:
        key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, xpath, 0, winreg.KEY_WRITE)
        winreg.SetValueEx(key, "ProxyEnable", 0, winreg.REG_DWORD, enable)
        winreg.SetValueEx(key, "ProxyServer", 0, winreg.REG_SZ, proxy)
        # 关闭自动配置脚本
        winreg.SetValueEx(key, "AutoConfigURL", 0, winreg.REG_SZ, "")
        # 设置刷新
        INTERNET_OPTION_REFRESH = 37
        INTERNET_OPTION_SETTINGS_CHANGED = 39
        internet_set_option(0, INTERNET_OPTION_REFRESH, 0, 0)
        internet_set_option(0,INTERNET_OPTION_SETTINGS_CHANGED, 0, 0)
    except Exception as e:
        print("ERROR: " + str(e))
    finally:
        None


def enableProxy(proxy):
    print(" Setting proxy")
    setProxy(1, proxy)
    print(" Setting success")

#关闭清空代理
def disableProxy():
    print(" Empty proxy")
    setProxy(0, "")
    print(" Empty success")

if __name__ == '__main__':
    enableProxy('42.51.13.68:16819')
    print(requests.get("http://dev.kdlapi.com/testproxy").text)
    time.sleep(1)
    disableProxy()
    print(requests.get("http://dev.kdlapi.com/testproxy").text)

Answer 1

After setting the IE options and registry, you have to press F5 key to refresh the IE browser or restart the IE browser. More detail information, you could check this link.

Edit:

Besides,we could also use the DefaultConnectionSettings registry key to set the IE browser proxy, please refer to the following steps and this thread:

1. Open Registry Editor
2. Navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections"
3. Check the "DefaultConnectionSettings" key value, it logs the proxy setting.

Answer 2

The reason is that in terms of refresh, both setting agent and closing agent need to be refreshed before they can take effect, and they need to be refreshed after they are closed before they can take effect

            _, reg_type = winreg.QueryValueEx(internet_setting, name)
            winreg.SetValueEx(internet_setting, name, 0, reg_type, value)

        return func(_set_key, internet_set_option, proxy_ip, ignore_ip)

    return __wrapper


def system_proxy_status():

    h_key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, SETTING_PATH, 0, winreg.KEY_READ)
    ret_val = winreg.QueryValueEx(h_key, "ProxyEnable")
    try:

    except Exception as e:

    return ret_val[0], ret_ser[0]


@_system_proxy
def open_system_proxy(_set_key, internet_set_option, proxy_ip=u"", ignore_ip=u""):
    """开启系统代理"""
    _set_key('ProxyEnable', 1)  # 启用
    if ignore_ip:
        _set_key('ProxyOverride', ignore_ip)  # 忽略的地址
    if proxy_ip:
        _set_key('ProxyServer', proxy_ip)  # 代理IP及端口
    internet_set_option(0, 37, 0, 0)
    internet_set_option(0, 39, 0, 0)
    return False if system_proxy_status()[0] == 0 else system_proxy_status()[1] == proxy_ip


@_system_proxy
def close_system_proxy(_set_key, internet_set_option, proxy_ip="", ignore_ip=""):
    """关闭系统代理"""
    internet_set_option(0, 37, 0, 0)
    internet_set_option(0, 39, 0, 0)
    _set_key('ProxyEnable', 0)  # 停用
    return False if system_proxy_status()[0] == 0 else system_proxy_status()[1] == proxy_ip

However, it is not feasible to set it twice in a row.

def main():
    open_system_proxy(proxy_ip="114.231.105.223:22322")
    print(system_proxy_status())
    open_system_proxy(proxy_ip="101.22.195.128:22619")
    print(system_proxy_status())

if __name__ == '__main__':
    main()

The result shows that the IP set twice is the same, although I give different proxy.I'm still looking for a reason

(1, '')
(1, '114.231.105.223:22322')
(1, '114.231.105.223:22322')
