1、前端页面调用showProxySettings() {chrome.send("showProxySettings")}
2、c++ 响应代码如下 chrome\browser\ui\webui\settings\system_handler.ccvoid SystemHandler::RegisterMessages() {web_ui()->RegisterMessageCallback("showProxySettings",base::BindRepeating(&SystemHandler::HandleShowProxySettings,base::Unretained(this)));
}void SystemHandler::HandleShowProxySettings(const base::Value::List& args) {base::RecordAction(base::UserMetricsAction("Options_ShowProxySettings"));settings_utils::ShowNetworkProxySettings(web_ui()->GetWebContents());
}3、chrome\browser\ui\webui\settings\settings_utils_win.cc// Connections tab selected.
void OpenConnectionDialogCallback() {// Using rundll32 seems better than LaunchConnectionDialog which causes a// new dialog to be made for each call.  rundll32 uses the same global// dialog and it seems to share with the shortcut in control panel.base::FilePath rundll32;base::PathService::Get(base::DIR_SYSTEM, &rundll32);rundll32 = rundll32.AppendASCII("rundll32.exe");base::FilePath shell32dll;base::PathService::Get(base::DIR_SYSTEM, &shell32dll);shell32dll = shell32dll.AppendASCII("shell32.dll");base::FilePath inetcpl;base::PathService::Get(base::DIR_SYSTEM, &inetcpl);inetcpl = inetcpl.AppendASCII("inetcpl.cpl,,4");std::wstring args(shell32dll.value());args.append(L",Control_RunDLL ");args.append(inetcpl.value());//通过shell方式启动系统代理设置//win10以下打开IE代理ShellExecute(NULL, L"open", rundll32.value().c_str(), args.c_str(), NULL,SW_SHOWNORMAL);
}void ShowNetworkProxySettings(content::WebContents* web_contents) {if (base::win::GetVersion() >= base::win::Version::WIN10) {// See启动的是SystemSettings.exe 代理// https://docs.microsoft.com/en-us/windows/uwp/launch-resume/launch-settings-app#network--internetplatform_util::OpenExternal(Profile::FromBrowserContext(web_contents->GetBrowserContext()),GURL("ms-settings:network-proxy"));} else {base::ThreadPool::PostTask(FROM_HERE, {base::TaskPriority::USER_VISIBLE, base::MayBlock()},base::BindOnce(&OpenConnectionDialogCallback));}
}

win10效果:
