C version selenium operation chrome full screen mode display (F11)

Recently developed a classroom intelligent control software , It mainly realizes the control of all electrical equipment in the classroom on the podium , It is mainly based on MQTT Realized , Its control interface uses WEB Page implementation .

The main control computer on the podium starts up and enters Windows Behind the desktop , Automatically run the browser and enter the control page . Because there is no user authentication on the control interface , So you need to hide the address of the control interface , Therefore, verification information is added to the entry address , Then go to the real interface . In order to see the startup more like desktop software , Therefore, the browser is also required to display in full screen （ namely ： Auto press F11 Enter full screen mode ）.

Method 1 ： By creating a Chrome Shortcut to , And add --kiosk Take realizable , As shown in the figure below ：

Then add it to Windows In the startup item of .

The only drawback of this method is ： You can't really hide the entry address of the control interface , People who know a little about computers can easily get the address . Use other devices to access this address to operate the device , This is what we don't want to see .

Method 2 ： Use automated testing tools Selenium Realize to Chrome Browser control . download Selenium Related to the class library , And download the installed with the local computer Chrome Browser version consistent ChromeDriver.exe. Download address is ：http://chromedriver.storage.googleapis.com/index.html 

The way to control the full screen of the browser is right ChromeOptions Set the properties of . Many people post on the Internet to maximize the browser and write the full screen of the browser , In fact, this is very wrong . The right way to do it is as follows ：

  ha-ha , I can't see the above picture clearly , I attach the code ：

        #region  Start browsing page 
        private void StartWebBroswer()
        {
            try
            {
                var option = new ChromeOptions();
                // Whether to hide the browser 
                // If commented out , Then it will open Google browser at startup , You can see the operation of filling in the form on the page , If you cancel , Only cmd window , Google browser runs silently  
                //option.AddArgument("headless");               // Headless mode （ That is, the browser runs hidden ）
                //option.AddArgument("window-size=1024,768");   // Specify browser size 
                if (this.ViewKiosk == "1")
                {
                    option.AddArgument("--kiosk");              // Full screen （ But press F11 Unable to exit full screen ）
                }
                else
                {
                    option.AddArgument("--start-fullscreen");   // All （ Press F11 You can exit the full screen ）
                }
                //option.AddArgument("--start-maximized");      // Browser maximization 
                option.AddExcludedArgument("enable-automation");// No display 【 Under the control of automatic test software 】 word 
                //option.AddAdditionalCapability("useAutomationExtension", false);    //
                // Set up cmd The window doesn't pop up 
                ChromeDriverService service = ChromeDriverService.CreateDefaultService(System.AppDomain.CurrentDomain.BaseDirectory.ToString());
                service.HideCommandPromptWindow = true;

                this.DriverObj = new ChromeDriver(service, option);
                this.DriverObj.Navigate().GoToUrl(this.ViewUrl);//https://www.baidu.com
                this.ExecutorObj = (IJavaScriptExecutor)DriverObj;
                this.ActionObj = new Actions(DriverObj);
            }
            catch (Exception xe)
            {
                this.WriteLogToFile(" Failed to start browser , reason ：" + xe.Message);
            }
        }
        #endregion

The code snippet above also includes headless mode to control the browser , Specify the size of the browser 、 Browser maximization 、 No display 【 Under the control of automatic test software 】 Words, etc , You can enjoy it . 

The following is a small tool developed in this project , stay Windows It is especially suitable for touch-screen devices , Support setting the starting address at will , Start up and run automatically 、 Kiosk mode and password protection , For your reference .
